Gasoline-electric hybrid VS electric VS oil-powered
I believe that many people will encounter this problem when buying a drone. Which plant protection drone should I choose?
Electric multi-rotor plant protection UAV:
a. The market for electric multi-rotor plant protection aircraft is between 30,000 and 150,000. At present, the threshold for multi-rotor plant protection aircraft is relatively low.
b. Load, endurance time and operating efficiency: The electric payload is generally 5L~10L, and the endurance time is generally 8~10 minutes. Every time you work, you need to change the battery while changing the dressing. Theoretically, the daily operating area is 300~500 mu.
c. Power cost: The life of the motor is a bottleneck that is difficult to break through. It can be used for about 50 times under the condition of fast charge and fast discharge. The manufacturer theoretically provides 300 times, but whether it can really achieve 300 times depends on your own practical experience. draw conclusions from the work.
d. Flight control operation, 80% of electric multi-rotor flight depends on flight control, 20% depends on pilot experience, light, flexible, easy to operate, low failure rate, low skill requirements for pilots, if the motor fails to input flight control Normally, the chance of multi-rotor bombing is very high. On the one hand, electric multi-rotors have a relatively advantage in the period when good operators are in short supply.
Oil plant protection UAV：
a. From the perspective of research and development, oil-powered drones need to develop engines, transmission mechanisms, and torque conversion mechanisms. Double the mechanical structure team or even more is required. What's more frightening is that because oil-driven drones will introduce additional vibrations, it is challenging for IMU design, which will greatly increase the cost of research and development.
b. From the perspective of life, oil-powered drones generally have a lifespan of 100 hours because of the large number of moving bearings, while electric drones have a lifespan of 1,000 hours or even more because there are only fixed bearings. high. In addition, the complex mechanical structure will greatly increase the training cost of maintenance personnel.
c. From the perspective of energy consumption, the efficiency of gasoline-powered drones is about 30%, and the efficiency of electric drones is about 70%. After a little calculation, we can know that the unit energy price of fuel is about three times that of electric drones. And because there are more mechanical parts, the load rate of oil-powered drones is lower. In general, if the maintenance cost is not considered, under the same plant protection effect, the cost of each voyage is about 4-5 times that of the electric. If maintenance is considered, it is about 10-20 times the order of magnitude.
Oil-electric hybrid plant protection UAV：
a. Strong endurance: Gasoline-powered UAVs typically have a longer endurance than electric UAVs, making them more suitable for long-duration missions.
b. Strong load capacity: Due to the use of internal combustion engines, oil-powered drones have a higher load capacity and can carry more payloads.
c. Relatively low price: Compared with electric drones, the manufacturing and maintenance costs of gas-powered drones are usually relatively low.
d. High speed: Oil-powered UAVs generally have higher speeds and are also easier to operate in adverse weather conditions.
In short, they all have their own advantages, and they all have bottlenecks that are difficult for users to accept. The so-called demand determines the market, and the future development depends on your needs.
