Drone Competition is Growing as a High Energy Sport

It was reported by the Wall Street Journal last year that the US billionaire, boss of the team Miami Dolphins , Stephen Ross has invested the Drone Racing League. He invested $1million through his investment company RSE Ventures. The industries of UAV have raised a question when the news came out: Is UAV contest a real sport? Nick Horbacezewski, CEO of the Drone Racing League said: "I think the game has the ability to let people resonate together because it has been not only a traditional racing game but also a game with new technology. Recently it has been reported that the drone competition is expected to become the next emerging sporting events. Unlike most racing sports such as car racing, horse racing or dog sledding there is no driver inside the drone. Drivers need to wear goggles, and they control it according to the video camera embedded in the front of the drone. Such manipulation is known as FPV (first person video). By combining FPV and UAV that participants and spectators could experience the speeds up to 90 miles / hour and give participants an immersive, high-speed flight experience of competition.

In the United States, the two-day U.S. National Drone Racing Championships held in California State Fair in 2005. It attracted 120 participants to participated in and the prize money is reaching a high of $ 25,000. It was reported that the game was expected to attract only 60 spectators, but the videos of UAVs hit on YouTube more than a million. Moreover in France, Australia and the United Kingdom the similar evevnts have been also organized.
In China in November 2015 the International Air Robot Contest (IARC) was held at the Beijing University of Aeronautics and Astronautics, the two play-offs multi-rotor UAV "Shepherd of Action" and "remote through" were added. And the competition rules was setting based on FPV model. Both playoffs game directly push the game to a climax and the applause, screams constantly which made the entire event completely a success.

With the growing popularity of the UAVs and virtual reality goggles equipment, consumer goods of science and technology are increasingly becoming affordable. Related associations, Unions strongly promote and integrate into the modern new technology with God's perspective of the world, the industry of UAV is bond to boil up and FPV drone competition will be growing as a high-energy movement.

Competition of UAVs is on the rise and development. it is a new industry and event planning and preparation will require a lot of time and manpower. The real development of drone competition takes time and it also faces many problems.such as the FPV battery flight time.

Currently, the UAVs on market mainly target lithium polymer battery as the main power. Endurance ability is typically between 20-30 minutes. There are some differences because of different technology but most of their flight time is less than 45 minutes while their charging time is more than one hour. The UAVs can not carry heavy battery with large capacity due to the need to minimize the weight of UAV. Most of the UAV just can maintain ten to twenty minutes in flight then it must be replaced by another battery or plug in the charging cable. So pilots often go out with three to four batteries which is regarded as a primary limits to the development of the UAV industry. To promote the development of the UAV marketing we should putting the problem how to prolong the flying time of UAV into the first place.

In September 2015 Tesla, a leader in the field of electric vehicles, announced a specific application of aerial UAV prototype. Company Tesla showed their scientificalness in rechargeable batteries. It was reported that the UAV was equipped with a 10000mAh battery and a single charge could promise a sustainable flight for 60 minutes and the charging time is only about 20 minutes. Tesla with unique skills has entered the UAV market and it is bound to have a tremendous impact on the domestic UAV battery. Everyone hope to have a kind of battery which charging time is shorter and flying time is longer. But this long-awaited product is still in the phase of conceptual designing.

The research on UAV battery has emerged in endlessly. Currently most of the new products are on the phase of research, and development of the UAVs battery can not be predicted. We hope these UAV battery can live up the expectations.

The application of drone in ecological protection

Due to the unique bird's-eye view, the drone can observe a wider range. The drone can offer you help no matter you are an agency selling real estate or you are a forest patrol.
In fact, drones, a cutting-edge technology, have been applied in ecological preservation areas, which would make the protection works easier. Let us see how it works.

In forest degeneration areas, the traditional plating method needs a large quantity of manual labors, which is time-wasting. In 2015, a new British company designed a drone, which can sow a special seed capsule into the soil. In practice, just like a bullet, the seed capsule would be shot and fixed into the soil. At the same time, the seed will rupture and can be exposed in the sunshine, then it will grow.

That drone can successfully sow ten seeds per minute, and it is estimated that a group of drone can sow 36,000 seeds for maximum every day.

However, the drone can be used before seeding. Scientists can take advantage of drones to make aerial photography towards the forest degeneration areas for the ground mapping. Moreover, the drone is able to supervise the illegal plant-cutting in the forest degeneration areas.

Supervise the habitats

The drones, with light weight and good performance, can shoot the detailed aerial photography, even converted into 3D model. Scientists can quickly identify the change of habitats when they use the drone to shoot systematically such as the periodic shooting for a certain area. The change of habitats can attribute to the the change of density of crown, erosion of river bed, quality and quantity of water, etc.

Drones can make aerial shooting for a large area in very short time. The scientists can analyze the change of the human activity, such as plantation destroy and expansion of the market around the particular habitats through image scaling.

fight against poacher

Drones can use with various tools, and one of them is thermal imaging camera. In some situations, this camera can transfer the video real-time to the researchers. Those two factors make the drones become the effective weapon to attack the poaching. Thermal imaging camera can shoot the human's appearance and shape through the trees and can track the campfire set by the poachers. Tracking poachers by drones is comparatively safe since the poachers often hold the weapons. Knowing the position of poachers contributes to the arrest, and stops the poachers from hiding.

tracking animals

The biologists in ecological preservation areas are using radio to track the displacement distance of animals and their habitat scales and judge whether the animals have entered the prohibited areas (non-preservation areas or human activity areas).

But the radio is regarded as an out-of-date method and time-consuming, because scientists have to go to the regular activity areas of animals in person, track the radio signal on foot and make record. In contrast, the drone can fly following the radio signal and collect the data and image more quickly, so that the scientists can track more animals and acquire more data.

Be against the forest fire

Thermal imaging cameras can also be used in investigating forest fires, avoiding the expansion of fires to cause the serious result. With the help of drones, people can make the quick reaction and control the fire easily.

But the drones can make more contributions to the forest fires. Till now, the firemen have always taken the planes or helicopters to observe the fires. Unfortunately, the firing areas are full of danger, such as the collision of several aircraft in a limited space. The drones can renew the the observation measure and guaranteed the safety of pilots and firemen.

Of course, if the drones are not the only equipment, the drones should cooperate with the aircraft very carefully and precisely.

Drones protect future

Undoubtedly, the drone has changed lots of fields, from estate selling to military activities. Recently, the drone has made contributions to ecological preservation areas and biological field. Now that the ecological protection has not made so much progress, the drone tech would definitely become a popular auxiliary.And also the UAVs flight time is a very popular industry, Gens ace &Tattu lipo battery has a few of reputation in the UAV field, if you interested, you can pay more attention to Gens ace 2s lipo battery and Tattu smart battery.

Battery Life Regarded as a Factor to Influence the Wind Direction of UAV

In recent years, with the rapid development of the UAV industry, A number of well-known enterprises such as Dji and Corbett Aviation emerged on the market and causes continued focus from capital and industry giants. However, the short flight time (general consumer drones only 20 minutes or so) still limit the application and development of the UAV. How to solve the problem of battery with short flight time? What role can IC products play in this area?

Flight time is less than 45 minutes but Charging over 1 hour

With the development of science and technology in recent years the application of UAV has expand from military to civilian areas, and it becomes more and more popular. According to the forecasts from research firm BI Intelligence, the next 10 years UAV will account for the UAV market share of 12%, valued at $ 98 billion. The current market size is 30 billion RMB in the UAV market. with the improvement of our airspace and UAV open regulatory policy, the next 10 years China's civilian UAV growth is expected to exceed 30%.
However, at the same time in the fast start of UAV market , the limited flight time and other constraints have gradually become prominent. Flight time has been a limit in the development of UAV technology. Currently, the UAV battery on market ofthen use lithium battery as the main driving force, and endurance is typically between 20-30 minutes. This is a major short board of the development of UAV, greatly limiting the overall potential of the UAV industry.
According to the reporter's investigation, the UAV on market including Dji and multi-rotor mostly use lithium batteries as an energy source currently. Because lithium batteries with mature technology are easy to purchase. But individual differences, incomplete balanced charge and discharge, and long charging time for high power battery make it more cumbersome to use. The biggest problem is flight time. Lithium battery with the weight of 300 grams theoretically allow UAV with 500 grams weight to flight 17 minutes, even taking into account the technical differences, as well as the body weight and other factors, the flight time of vast majority of UAVs are all within 45 minutes. But the charging time is more than one hour.
Therefore, it is a challenge for all UAV manufacturers must face: how to enhance UAV endurance and allowed them to meet consumer or even industrial market demand.

Power management chip technology plays a important role of UAVs on market

The biggest problem we are facing is the lithium battery of UAVs with short flight time. It is no breakthrough in the material of lithium battery.In that case, there are two ways to solve the problem: some manufacturers began to try new replacement materials for lithium battery ; Adopting technology of power management chip to achieve effective energy management. Prolong flight time of battery to the utmost extent and charge battery fast.

HUS company in Singapore developed the first multiaxial UAV HYCOPTER using hydrogen fuel cell in May 2015. It can fly continuously for four hours with no load, even under full load of 1 kg can still support 150 minutes. Currently, Dji, Corbett aviation and other manufacturers are also making use of hydrogen fuel cells attempt.
However, as the most common materials, lithium battery with solid power, mature technology, and the use of safety are still the most preferred electricity choice for consumer drones. For example, in September 2015, a leader in the field of electric vehicles, Tesla publicly announced a specific application of aerial UAV prototype. With its strength in battery and power management technology, a UAV from Tesla equipped 10000mAh battery. It can fly 60 minutes a single charge, and the charging time is only about 20 minutes.

In this case, the superior power management chip technology has become one of the key factors to affect the success or failure of the UAV market.

The key point is to find a balance charge

So how the current power management chip technology develop in the UAV market? According to reports, battery management chip is a kind of chip to perform condition monitoring, security management and charge management of battery of electronic device. It can control the voltage of charge current , promise the security of battery, and predict accurately on remaining capacity of battery. IC performance of battery management has a great impact on the operation and use of electronic security equipment

Power management chip has very broad applications, and it is widely used in smart phones, laptops, charging treasure, tablet PCs, smart wearable devices and other products. At the same time, as the quantity of electronic products increases using the power management chip to achieve fast charging has been in the leading place on market.

UAV is the most promising market to achieve fast charging. According to reports, from power management chip, there are similar solutions between smart phones and UAVs. However, charging the phone is subjected to the restriction of USB interface and battery. USB interface typically supplies at 5V . Currently, the highest voltage of mobile phone battery is generally 4.2V, and the high voltage of fast charge eventually drop itself to a voltage the phone battery can withstand and then increase the current to achieve fast charge. The Principle of UAV fast charge, although the same with mobile phone, need to increase their voltage or current, but the difference is, the battery may be made up of several lithium cells (such as three cells 3 * 4 = 12V, that is, to charge the battery at 12V). Because the realization of the tandem cell, we need to consider the balance charging problem to prevent the accidents caused by charge imbalance.

As for the future technological development, on one hand, fast charge technology of the mobile phone is trying to find a high voltage (such as 12V) for mobile phone into a high current. On the other, attention need to be paid to the phone adapter and communication protocols to prevent high voltage burning the phone . There are no restrictions in UAVs, and it is the fastest as long as each cell can withstand the maximum voltage and current. Therefore, there is great room for the development of the technology of UAV fast charge in the future.

Why my drone simple to crash?

As the drone more into people's lives, the crashing drone inevitably come to be to a scorching topic, since for being truthful, frying a machine is as well uncomplicated,while the worst knowledge a drone pilot can face is crashing or shedding your drone through flight. Plenty of new classmate don't have very good instruction, or lack of corresponding processing experience, they normally crashed of ignorance, the causes are various.the reason may be divided into two broad categories:

Prior to flight:

No calibration of GPS and also the compass;
No number of stars on GPS, weak star flight;
Didn't tighten the screw. Propeller should verify once again;
Didn't verify the electric amount of 22.2v Lipo battery. Many people will put together numerous batteries, at times,but they did not press the button to view if the energy enough once they very first fly;
Unfamiliar with the remote control , do not even know when they accidentally set to Japan's hand.

Throughout flight:

Bump a tree, developing, hit anything at all;

Lack of control skill bring about the disorder direction right after the drone fly over-the-horizon;

With the interference spot in the course of flight;

Ignored the sudden wind or windy weather;

From brake management bring about drone roll fell.
To assist you avoid this predicament, we're going to explain the biggest dangers to you and everything you can do to prevent them.

Know Your Drone Piloting Abilities

The biggest danger for your drone is oneself, in particular should you're a brand new pilot or doing work with unfamiliar products. The odds are if some thing goes incorrect throughout your flight, you triggered the issue!
Start out out lower and slow. We all know the best joys of flying a drone can come from soaring around higher up inside the sky, maybe even capturing some killer video, but you have to learn while flying 15-30 feet off the ground just before taking it any higher. For the duration of a worst-case scenario (heading to get a tree/building, operating from battery, losing handle, etc.) you have to get your drone back to the ground ASAP.
Treat New Equipment being a New Drone. If you include new equipment to your drone (like attaching a new camera on your Phantom), treat your flight as though it's a totally new drone you might want to master. Matters like dealing with and RC Lipo battery life might be impacted and could bring about some poor outcomes in case you treat it as though absolutely nothing has modified.

Steer clear of Obstacles

This goes along with flying inside of your limits, but one of the most typical causes of crashes are attributable to flying your drone into objects like trees and buildings. It's also one of the simplest methods to drop your drone acquiring it caught with the top of the 60 foot tree, or on leading of a building you don't have entry to (plus the owners may well not be so great).

Start off out by flying in an open field, away from any trees, buildings, bodies of water, or roadways. This is actually the safest method to make certain your drone comes dwelling with you.

Weather Can Kill Your Drone

An additional important threat for your drone is weather itself. Thankfully, it's very easy to prevent in case you just place within a little time researching climate reviews ahead of hand.
Check the climate report prior to you fly If there's a chance of rain, conserve your flying for a different day! Superior to get protected than have your drone come crashing to the earth resulting from technical malfunctions from having moist.
Know the wind gusts. Make sure you check out the current wind ailments on the weather app in advance of take-off. Most novice pilots can manage wind speeds of 5-10 MPH with out a lot problem. In case you see wind speeds at 15 MPH or over, you must reconsider flying near any obstacles or with a lot of altitude. You might uncover your drone caught in the wind gust that didn't exist at reduce altitudes, and it could carry your drone away or capsize it.

The Prohibited Areas Of UAV Flight

There are increasing people playing the drones. Although many countries do not have the complete monitor system, some countries have the law to confiscate your drones. As a pilot, the first thing you should know is that flying in some areas is prohibited. Tattu, specialized in the UAV battery, will introduce you some prohibited areas. Hope that help!

1.Airport

Once, the drones interfered the take-off of the plane, and the military helicopters are used to solve this problem. There is no bird in the airport, not to mention the drones. And China has clear law to clarify that the airport and its surroundings cannot have UAVs. The manufacturers have updated their product, which will stop the engine if the symbol of airport has been found.

2.Business district and the crowd

For others' safety, please choose the empty space to fly.

3.High-voltage wires

There is interruption around the high-voltage wires. Though the human cannot feel it, the UAVs cannot stand it. It is common to see the drones fix the wires, but those drones have been refit or custom-made.

4.Base station of mobile phone

Compared to the high-voltage wires, the base stations are often ignored, because they exist everywhere and hard to find. The base station can launch the radio, which undoubtedly interfere the drones. Furthermore, the base station interfere more the remote signal between the drones and the ground, especially the new built 4G base station. It has been proved that the 4G base station has evident interference to the 2.4G remote signal of Futaba, which shows the dramatically shortened remote distance. In cities, we should escape the roof of building where has established the base station. If you notice the dramatically shortened remote distance, please observe whether there has base station.

5.The indoor stadium without GPS

Please choose other suitable place, unless your drone has visual location system which support to fly indoor.

6. Under strong wind or bad weather

The common drones can bear the wind of Level 4-5. Do not challenge your drone in the 5th level of wind.

7. the metal facility.

It has strong interference.

8. military center and government

the restriction varies from country to country. We should pay attention to such information before flying. and also choose a better battery,such as Tattu 22.2v lipo battery,Gensace & Tattu hope everyone enjoys the UAV flight!

Can Gasoline Engines Replace UAV Batteries to extend UAV flight time?

Flight time has been a very vexing problem for most of UAV hobbyists. Generally speaking, the flight time for the high end consumer-level UAV is about 25mins; however, the flight time of UAVs for commercial use is not that long.

Many companies desire longer flight time for their own UAVs and are depressed by a constant replacement and charging for the batteries. Most UAVs are powered by the high-end lipo batteries, also regarded as the low energy density battery. That is to say, as to its voltage, the volume of this battery should not be that big. It is unrealistic get a longer flight time for the UAVs by just adding the batteries packs.

After the research and development, Pegasus has come out with a solution of using gasoline instead of using batteries. This company is now having a beta test for the GE-30RangeExtender system, which is a gas-electric hybrid that can be inserted in the battery terminals for most of the commercial- level UAVs. The flight time for the current UAVs is lengthened to 2 hours owing to this system, and it is possible that this system would be used for the bigger models in the future.

The gasoline can bring more energy than the battery according to energy density. A record from the American Institute of Physics shows that the energy of a car filled with gasoline equals to the energy that a thousand dynamite rods can make, and the energy density of the gasoline is 50 times higher than the UAV battery.

In essence, RangeExtender is the two-stroke internal combustion engine that fits for the UAVs though it is not as easy as it sounds. You can not just install the rotors on the grass trimmer to make it fly, or maybe someone has already done this before. Of course, you can make an UAV that looks like a grass trimmer, but that would be a different story.

RangeExtender is a system of gas-electric hybrid made from Pegasus, which can generate appropriate power to wheels, but it is not equipped with electric engine and gas engine as the hybrid electric. RangeExtender is not just mechanically integrated with the UAV but a micro edition of the power system used by large ships. It converts the energy powered by the gas engine into electric power and provides power for the electric motor to make the propellers work.

A good news is that RangeExtender can be purchased in this late summer. RangeExtender would be used by large commercial UAVs. Till now, Pegasus has not mentioned the price, but it has put forward by the MattMcRoberts that RangeExtender would cost far less than $12000 of an annual expense of the batteries for most of commercial UAV operators.
Pegasus is not the first company who's tried to solve the existing problems for the UAV battery. TopFlightTechnologie from Massachusetts has tried to use generator, powered by gas engine, to charge for the UAV batteries. The hydrogen fuel cell provided by the UK IntelligentEnergy can also extend 2 hours' flight time for the UAVs just as the Pegasus system.

Of course, nobody gets cheered by the gas-powered UAVS besides the operators who use commercial UAVs to survey the petrol pipeline or mine. According to the record of US Energy Information Administration, a gallon of petrol could produce nearly 20 pounds of carbon dioxide. The gasoline, maybe, can not replace the UAV batteries but it is a new step forward towards the UAV flight time issues. Grepow is now achieving great success in UAV batteries, and many UAV pilots are getting impressed by its new smart battery-Tattu battery. You may also take a look at the tattu batteries if you're interested in it.
