It generates high-temperature and high-pressure gas by compressing air and mixing fuel combustion to drive the turbine to rotate and backwardly inject to form thrust, thereby providing the required power for the aircraft to fly. In the technical evolution from the piston to the jet, the modern mainstream turbofan engine takes into account high efficiency and low noise characteristics with high bypass ratio design.

This allows the cylinder head to shake and impact with the cleaning fluid, enabling the cleaning fluid to dislodge carbon deposits in the holes on the cylinder head, thereby improving the cleaning effect. Furthermore, the second servo motor drives a turntable to rotate, which in turn causes the mesh frame and cylinder head to rotate laterally, further improving the contact effect between the cleaning fluid and the cylinder head, thus further enhancing the cleaning effect. When the first servo motor drives the first gear to rotate, it can drive the winding wheel to rotate, thereby winding up the pull rope on one side, which in turn drives the sliding block to move upward, thereby lifting the lifting plate and raising one side of the cylinder cover, allowing liquid to enter the underside of the cylinder cover. Then, when rotating to the other side, the other side of the cylinder cover can be raised, thus alternately raising the cylinder cover, which helps to improve the contact effect between the cleaning fluid and the bottom of the cylinder cover, thereby further improving the cleaning effect. The first servo motor drives the mesh frame to rotate reciprocally, and the second servo motor drives the mesh frame to rotate laterally. This allows the cleaning liquid on the cylinder cover to be thrown off when the material is lifted, thus helping to avoid dripping during transfer. Attached Figure Description
