Cyclone air-breathing aero-engine and driving method thereof

Abstract

The invention discloses a cyclone air-breathing aircraft engine and a driving method thereof, and aims to improve the problems that a traditional aircraft engine is low in thrust-weight ratio, the weight of a high-thrust engine is heavy and the like. The aircraft engine comprises a turbojet engine, an air inlet pipe is connected with an air discharging port of the turbojet engine, a cylinder is connected at the other end of the air inlet pipe, a cylinder end port A is formed in one end surface of the cylinder, a cylinder end port B is formed in the other end surface of the cylinder, the diameter of the cylinder end port B is larger than that the cylinder end port A, an air inlet approaches to the cylinder end port A, the air inlet pipe is positioned on the tangent line of the cross sectionof the cylinder of the air inlet pipe, helical blades are fixedly connected on the inner wall of the cylinder, spiral grooves are formed among the helical blades and the inner walls of the cylinder,a plurality of oil spraying holes are formed in the inner wall of the cylinder of the spiral grooves, and an igniter is arranged in the cylinder.

Description

technical field [0001] The invention belongs to the field of engines, and in particular relates to a cyclone air-breathing aircraft engine and a driving method thereof. Background technique [0002] An aero engine is a highly complex and sophisticated thermomechanical engine that provides the power required for aircraft to fly. As the heart of an aircraft, it is known as the "Flower of Industry". It directly affects the performance, reliability and economy of an aircraft, and is an important manifestation of a country's technological and industrial strength. The thrust-to-weight ratio of the engine is an important parameter. Thrust-to-weight ratio, that is, the ratio of the thrust generated by the engine to the weight of the engine itself, the greater the ratio, the better the power of the engine. Therefore, the thrust-to-weight ratio is a measure of the actual performance of the engine. [0003] Existing aero-engines generally have the problem of low thrust-to-weight rat...
