Planetary gear paddle fan combined engine device

Technical Field

The invention belongs to a navigation propeller, and particularly relates to a planetary gear and propeller fan combined engine device which can be used for aviation flight, water surface navigation propulsion and other fluid propulsion.

Background

The existing electric airplane power system generally adopts a propulsion mode that a motor directly drives a single group of propellers, and is similar to a single-engine single-propeller mode of a traditional piston engine or a turboprop engine, and the electric airplane adopting the structure mainly has two problems: first, the single propeller power system has the problems of low propulsion efficiency and high noise. The requirement for the motor to have large driving force and high rotating speed is high, when one winding of the double-winding motor in the prior art is damaged, if the remaining winding is required to work at full load, the heat is often very serious, which is a great defect of the prior double-winding motor and is limited by the energy density of a battery and the total weight of an airplane, and the efficiency of a power system is not high.

Secondly, the reverse torque generated by the acting of the motor influences the structural design and the flying operation of the airplane, the single-propeller electric airplane can generate torque opposite to the running direction of the propeller when sliding on the ground and flying in the air, in order to avoid the influence of the reverse torque on the flying, the structure of the airplane is generally changed and certain operation action is adopted to overcome the reverse torque, for example, in the design of the airplane, a mode of horizontally offsetting the engine from left to right and vertically and special structural compensation are carried out on an aileron and a rudder; at the same time, the pilot is also required to perform certain operations to overcome the counter moment during flight.
