Problems solved by technology

[0003] The aviation hybrid power system has a compact structure, and generally uses a simple carburetor to adjust the air-fuel ratio at the engine end, but this compact carburetor mechanism does not have the function of automatically adjusting the fuel supply. The amount of air that can be inhaled by the aviation hybrid system gradually decreases, but at this time the oil supply of the carburetor has not been adjusted accordingly, resulting in a decrease in the output power of the hybrid system, which in turn affects the maneuverability of the UAV, and even causes the engine to fly high. Flame out, causing a safety accident
On the other hand, the non-adjustable fuel supply will inevitably lead to a reduction in fuel economy

Abstract

The invention relates to the technical field of high-altitude power compensation for aviation hybrid power systems, and specifically discloses a high-altitude power compensation adjustment control method for aviation hybrid power systems: measure and calculate the intake oxygen concentration of the hybrid power system according to atmospheric pressure and ambient temperature, and calculate the intake oxygen concentration according to real-time Oxygen concentration conditions, adjust the fuel supply of the carburetor, and realize the real-time online variable adjustment of the air-fuel ratio. It is to make the aviation hybrid system work in the best efficiency mode at low altitudes; at high altitudes, to compensate for the aviation hybrid system. Power output to make it work in the best power zone. On the one hand, the invention increases the fuel economy of the aviation hybrid power system, thereby improving the endurance time; on the other hand, it compensates the power output and increases the allowable flying height of the drone.

Description

technical field [0001] The invention relates to the technical field of high-altitude power compensation of aviation hybrid power systems, and is also suitable for high-altitude power compensation of aviation piston engines. Background technique [0002] Due to its long battery life and strong load capacity, the micro-miniature aviation hybrid power system is a commonly used power system solution for industrial drones. The core components of the micro-miniature aviation hybrid power system for industrial drones are high-speed two-stroke small-displacement piston engines and high-speed permanent magnet synchronous motors. The motors are driven by the engines to generate electricity, and the output power is used by drones. The flying altitude of the UAV is affected by the region, ranging from 0m to 4000m above sea level. As the altitude increases, the atmospheric pressure and oxygen concentration decrease significantly. Therefore, the working environment of the aviation hybrid ...
