Embodiment Construction

[0029] The present invention will be described in further detail below through specific embodiments and in conjunction with the accompanying drawings.

[0030] The existing structure of the power installation of the electric aircraft pulled forward by the axis: such as figure 1 As shown, the motor 1 and the motor bracket 5 are connected by bolt I6; figure 2 As shown, the motor bracket 5 is then connected to the plate 8 through bolt II7; image 3 As shown, the motor 1, the motor bracket 5, the plate 8 and the fuselage 9 are assembled and connected; Figure 4 yes image 3 In the enlarged view of area A, the plate 8 is buckled or bonded to the fuselage 9 . The existing structure has the hidden danger of the motor falling off due to the loosening of the bolts, the disassembly and assembly of the motor is inconvenient, and problems such as heat dissipation, vibration reduction, and anti-collision are not considered.

[0031] In the first solution of the present invention, the ...

Abstract

The invention discloses a power installation structure for an electric aircraft with an axis pulled ahead and includes two technical schemes. One technical scheme includes that the power installation structure comprises an installation base and an elastic structure, one end of the installation base is connected with a motor through bolts, the other end of the installation base is connected with the elastic structure through threads, and the elastic structure is fixedly attached to an aircraft. The other technical scheme includes that the power installation structure comprises a modified motor and the elastic structure, and the motor is in threaded connection with the elastic structure fixed attached to the aircraft. When the motor runs, reaction torque of a rotor enables threaded connection between the elastic structure and the installation base in the first scheme or the motor in the second scheme to be self-locked. The power installation structure functions in heat dissipation, anticollision and vibration attenuation, improves motor disassembling and installing efficiency of the aircraft, eliminates hidden danger of falling off of the motor, and prolongs single operating time of the aircraft.

Description

technical field [0001] The invention discloses a power installation structure of an electric aircraft pulled forward by an axis, and belongs to the field of aviation electromechanical technology. Background technique [0002] The active power of the aircraft is generally provided by a heat engine or an electric motor. The noise of the motor is usually much smaller than that of the heat engine, which makes the electric aircraft more concealed, especially the small and medium-sized electric aircraft. This feature makes the electric aircraft have a higher survivability on the battlefield, and has less impact on the environment in civilian use. In addition, the fuel of a heat engine is usually flammable and explosive, so electric aircraft are relatively safer. [0003] The motor is the core component of the power system of an electric aircraft, and the installation method of the motor is even more related to the overall performance of the aircraft. The connection between the ...
