Air-driven ducted fan jet propulsion power system

Abstract

The invention discloses an air-driven ducted fan jet propulsion power system, comprising a core turbine, a ducted fan connected to the core turbine through an air induction pipe, and a blade tip turbine coaxially installed with the ducted fan, the core turbine exhausts gas It is transmitted to the blade tip turbine, and the blade tip turbine works on the expansion of the gas, driving the bypass fan to rotate and inhale the air to generate thrust, which breaks through the design limitation of conventional turbofan engines with large bypass ratio, greatly increases the bypass ratio of the engine, and further exerts its large capacity. The basic principle of bypass ratio turbofan engine to improve propulsion efficiency, lower fuel consumption and higher power output, and the function of the induction pipe connected between the energy source core turbine and the bypass fan is only the airflow channel without complicated machinery The connection can be arranged inside the fuselage and wings according to the design needs of the aircraft, giving the aircraft a more flexible layout.

Description

technical field [0001] The invention relates to the technical field of aircraft power, in particular to an air-driven ducted fan jet propulsion power system. Background technique [0002] Straight take-off and landing technology is a technology that has emerged since the 1950s and 1960s. This technology can help fixed-wing aircraft reduce or basically get rid of their dependence on runways, and only need a small flat ground to achieve fast and safe take-off and landing. Therefore, aircraft with vertical take-off and landing capabilities do not require special airports and runways, and are highly adaptable to terrain. They can be distributed or equipped on ships, which is convenient for flexible attacks, transfers, camouflage and concealment, and can complete other fixed operations such as hovering in the air. High-difficulty actions that cannot be completed by wing aircraft; with the innovation of foreign vertical take-off and landing aircraft concepts, the most important te...
