Abstract

The utility model discloses an electric vertical take-off and landing manned aircraft which comprises an aluminum alloy rack and a vibration reduction assembly, one side of the aluminum alloy rack is connected with a right guardrail, the other side of the aluminum alloy rack is rotatably connected with a left guardrail through a winding shaft seat, and the vibration reduction assembly comprises a first carbon fiber tube and a vibration reduction seat sleeved on the first carbon fiber tube. An upper vibration reduction seat and a lower vibration reduction seat are fastened through bolts at the penetrating position of a first carbon fiber pipe and an aluminum alloy rack, a rubber vibration reduction pad absorbs high-frequency vibration energy through elastic deformation of the rubber vibration reduction pad, direct transmission of vibration to the rack is effectively blocked, and an axial anti-rolling support elastically clamps a sleeve through a rubber clamp, so that the vibration reduction effect is improved. The clamping force can be flexibly adjusted through the hardness of the rubber clamp, the vibration feeling of a cabin area is greatly reduced, the first carbon fiber tube and the second carbon fiber tube are both made of carbon fiber composite materials, the reflection capacity of the materials to sound waves is weak, and the transmission efficiency of aerodynamic noise of the propeller can be reduced.
