Description

Technical Field

[0001] The present invention relates to the technical field of plasma-propelled aircraft, and in particular to a plasma-propelled ultra-quiet flying robot system and a power combination control method. Background Art

[0002] The China Aerospace Research Institute (CASI) published its 2019 "Electric Aircraft Development White Paper," emphasizing that electric aircraft, which use electricity as a propulsion system energy source, are a key initiative for the aviation industry to implement green aviation and address global environmental challenges. Compared to conventional aircraft, electric aircraft offer advantages in energy conservation, emission reduction, and noise reduction, and thus hold broad development prospects. Key technologies for electric aircraft include overall design, integrated energy management, and efficient, high-power-to-weight ratio electric propulsion. In terms of electric propulsion, the current mainstream implementation focuses on improving existing brushless DC motors and developing superconducting motors. Ultimately, direct propulsion still relies on the motor driving the propeller. While low-noise, high-efficiency propeller technology has been developed, the inherent noise generated by propeller rotation remains difficult to eliminate. This disadvantage limits their widespread use in densely populated areas such as cities and also hinders defense requirements for silent reconnaissance and strike capabilities.

For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; and direct or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of these terms in the present invention depending on the specific circumstances.
