AI Technical Summary

Technical Problem

Existing drones have limited power output in high-altitude and plateau environments. In particular, piston-engine and electric drones cannot fly for long periods of time, and turbojet engines have altitude limitations, making it impossible to take off and climb normally.

Method used

It adopts a power layout of piston engine and turbojet engine, one pulling and one pushing, and combines the power controller to coordinate the working state of the two. The ECU controls the speed, thrust and fuel injection of the piston engine and turbojet engine to achieve optimal power output.

Benefits of technology

It broadens the performance and service ceiling range of UAVs in high-altitude and high-velocity environments, maintains the economy of continuous flight, and enables UAVs to fly freely at altitudes of 5,000-8,000 meters.

Abstract

This invention provides a drone for high-altitude plateaus and a power control method. The drone includes a twin-boom fuselage and a power controller. A piston engine with a propeller is located at the front end of the fuselage, which generates a forward thrust by driving the propeller. A turbojet engine is located at the rear end of the fuselage, which generates a backward thrust to propel the fuselage forward. The thrust and pull are in the same direction. The power controller is located on the fuselage to control the rotational speed of the piston engine and the thrust of the turbojet engine. This invention, through the hybrid power layout of the piston engine and turbojet engine, expands the endurance economy and service ceiling range of low-cost drones, successfully breaking through the altitude barrier of 5,000 meters, enabling low-cost drones to freely fly at altitudes of 5,000 to 8,000 meters, and realizing high-altitude flight of low-cost drones in plateau regions.
