Description

Technical Field

[0001] This invention relates to the field of aviation hybrid power technology, specifically to a high-power integrated heat dissipation vortex-electric engine with a front-mounted motor. Background Technology

[0002] A high-power motor is integrated into the front end of a turbine engine, and the eddy-electric hybrid propulsion device utilizes the engine's own system to achieve efficient heat dissipation. It is suitable for scenarios requiring high-power-density propulsion systems, such as UAVs and general aviation aircraft.

[0003] The aforementioned device lacks a coaxial direct drive, high speed, and high power-to-weight ratio structure during use. As a result, the mainstream structural solution for existing turbine hybrid electric propulsion engines is to place the motor behind the turbine and extract the turbine shaft power through an accessory gear transmission device. The gear transmission then drives the generator to rotate and generate electricity. This type of turbine hybrid electric propulsion engine with accessory gear transmission has a complex structure, large size and weight, and high overall operating cost. Based on the shortcomings of existing technology, this invention designs a high-power integrated heat dissipation vortex-electric engine with the motor positioned in front. Summary of the Invention

[0015] Compared with the prior art, the present invention has the following beneficial effects: This is a high-power integrated heat dissipation eddy current engine with a front-mounted motor. The generator mechanism is located before the compressor body. The gas generator body, consisting of a combustion chamber, a gas generator rotor, a turbine disk, and a turbine body, generates high-temperature and high-pressure gas. The motor spindle is coaxially arranged with the gas generator rotor via a spline sleeve and a spline head.
