There are many types of drones on the market, and the scope of application is wider and wider. The drone capacity in the market is generally between 20 minutes and 30 minutes. The charging time is more than one hour, which limits the flight time of the drone. And flight distance. However, battery life has rarely improved. EVTank's research report pointed out that the current life cycle of consumer-grade drones is generally within one hour, mainly using lithium polymer batteries as the main driving force. There is still much room for development in the future of drone fast charging technology. Here are some recommended drones with a long battery life, focusing on the HYDrone-1800 drone, and the endurance ability makes Dajiang tremble. However, the longer the life of the drone, the better? Xiaobian also gave you an analysis for reference.
UAV with long battery life - Expedition No. 6 (early domestic)'Expedition No. 6' series of UAVs, "It can cover 150-6000 meters of near-Earth space, and it has the flexibility of UAV and the high sensitivity of superconducting magnetometer. It is the future exploration of underground mineral deposits in China. One of the core equipments.†Huang Xiaosong introduced that the development of the drone is the responsibility of the atmosphere, and the development of the core load superconducting magnetometer is the responsibility of Shanghai Microsystems. The wings are 8.1 meters wide and the body is 4.7 meters long. It can hold 4 fuel tanks at a time and fly for more than 30 hours. In the state of good aerodynamic design of fixed-wing aircraft, multi-loaded oil can fly for a long time. In this respect, our country should not be worse than others. In addition, in the HM, there are also two or three batteries that go out to fly electric gliders for one afternoon, and even DLG or free-flying ones do not use batteries in one afternoon.
It can carry 5 kg of weight, the speed reaches 120 km / h, the maximum flying height is 5000 m; the endurance is 90 minutes, vertical, vertical drop, redundancy technology and reconfigurable power system, the motor is half dead, and can fly, All-weather complex terrain autonomous flight, low Reynolds number small paddle propeller rotor: freely switch between hovering and leveling; side paddle and vector thrust technology, more efficient, pure power; carbon fiber aramid honeycomb core composite, more Stronger and lighter.
Long-life drone - HYDrone-1800 (emphasis)On April 10, 2016, the world's first productized hydrogen fuel multi-rotor industrial-grade drone, the HYDrone-1800, was launched in Shenzhen. The drone has a battery life of 273 minutes for power, petrochemical and security. , fire and other fields.
With 6-axis design and full carbon fiber molding, it can realize industrial three-proof (fireproof, rainproof and dustproof), with maximum load of 25KG and maximum flight radius of 100KM. It also has ultra-long-distance image transmission, over-the-horizon remote control and precise positioning navigation. And other functions. The HYDrone-1800 uses a hydrogen fuel cell. The stack portion of the fuel cell is provided to the partner, and back-end control and packaging and subsequent maintenance are performed by Corbett. According to Corbett, the endurance is divided into several levels depending on the cylinder: 5L is about 90min, 9L is about 180min, and 14L is about 270min.
There is a saying now: smart phones look at the iPhone, drones look at China, HYDrone-1800 attracts the attention of the local tyrants in the Middle East, life is just one of the selling points, and many other highlights
The drone uses a hydrogen fuel cell, and the hydrogen fuel cell is commonly used in the military industry, and the development in the consumer class is not smooth.
Produce electricity through a hydrogen cylinder and a hydrogen chemical reaction
Hydrogen is the lowest known gas in the world, and it has the disadvantage of large capacity, heavy weight and large power consumption of lithium batteries.
Hydrogen fuel cells can achieve long-term battery life, but there are also several problems: the source of hydrogen, the scarcity of metal platinum (metal platinum is used as a catalyst in the hydrogen fuel cell power generation process), and the safety of hydrogen.
First of all, the source of hydrogen, the content of hydrogen in the air is very small, and generally exists in the high altitude, so it is not easy to extract hydrogen. Usually, the method of producing hydrogen includes electrolyzing water or preparing from natural gas and water gas. Method, the cost will not be very low. Followed by metal platinum, platinum is a chemical element, its single substance is commonly known as platinum, its cost is very expensive, this can refer to the price of platinum ring. Finally, there is a safety issue. Hydrogen is the world's smallest known gas and is a flammable and explosive gas. That is to say, when you fly a drone, it is equivalent to playing a bomb. You don't know when it will happen. explosion.
To solve these problems means that the cost will be very high, so hydrogen fuel cells have been used in the military industry for many years, but in the consumer sector, the development is not smooth.
The hydrogen fuel cell used in the HYDrone-1800 is reported to have strong safety performance, and its fuel cell is 1/3 to 1/5 of the capacity of a lithium battery of the same capacity. Of course, the price of the battery is also very expensive, it is reported to be in the tens of thousands.
This hydrogen battery needs to be activated once every 5,000 flight hours, which can be thousands of flights.
Each hydrogen cylinder is about 80 yuan and can be inflated 5-8 times. For every 10 yuan, the comparison of lithium batteries is not too expensive, the more important the number of uses will affect performance.
The 5-liter cylinder is driven for 90 minutes, the 9-liter cylinder is 180 minutes, and the 14-liter cylinder is approximately 270 minutes.
The HYDrone-1800 is a 6-axis design with a wheelbase of approximately 1.8 meters, a maximum load of 25 kg and a maximum flight radius of 100 km.
Full carbon fiber molding, can achieve industrial grade three defense (fire, rain, dustproof)
The large six-axis drone is divided into three pieces, with a full carbon fiber design, the body weight is only equivalent to a large bottle of Coke, and supports quick release.
Even if the single paddle accident occurs, the built-in parachute can be safely lowered in 0.5 seconds.
In extreme cases, the parachute is automatically turned on to ensure an effective minimum height of 50 meters.
HYDrone-1800 realizes CM-level precise positioning navigation, over-the-horizon remote control and ultra-long-distance image transmission.
On the military side, it is possible to accurately target enemy targets and open up attacks.
The aircraft with a large load is too expensive. However, as a farm implement and a labor tool, the plant protection drone has a cost-effective problem. There is a close relationship between the load and the battery life.
Most of the loads are mostly oil-powered helicopters. The continuous operation of the oil machine has not been recognized by users. They all think that large-scale oil-powered helicopters are suitable for large-area farms and will be completed in 1-2 hours.
However, considering the agricultural operation environment in China, large-scale farms are concentrated in the northeast, Inner Mongolia, Xinjiang and other regions, while the southern hilly areas are more complicated, and they also have higher replenishment of their medicines and battery life while plant protection machines. The requirements are more applicable to power-driven drones.
Foreign companies have developed a number of companies that provide data analysis services. According to the statistics of Yuchen.com, in 2016, among the companies with large financing amounts in foreign-related UAV-related fields, companies with data analysis and services accounted for a large proportion. . However, domestic awareness of data collection and analysis seems to be weaker. At present, there are no large data providers and analysts. Naturally, this is related to the short development time of civil drones in China.
Therefore, in the field where civil drones are currently applied, in addition to logistics and plant protection, the balance between endurance and load is relatively high, and more UAV applications, such as aerial photography, power line inspection, scientific investigation, and forest fire prevention. Inspections, military reconnaissance, police use, etc., are not necessarily flying as long as possible. The purpose is to obtain different data, which may be image data, or analytical data obtained by carrying different pods. Therefore, it is useless to emphasize long life.
Xiao Bian recommended: China's civil drone ranking _ civilian drone which is strong?
