Abstract

The invention provides a metal powder fuel air-water cross-medium engine and a control method thereof. The engine has the capabilities of jumping water and air at multiple frequencies, flying at the speed of Ma0-4.0 and working at a high speed underwater. According to the metal powder fuel air-water cross-medium engine, an air turbine rocket engine mode, a subsonic combustion ramjet engine mode and a water ramjet engine mode are organically combined, the engine can work in water and air media through engine flow channel adjustment, the working modes can be automatically switched according to the external environment, and the engine has the wide speed range and high-performance working capacity.

Description

technical field [0001] The invention belongs to the field of air-water cross-medium engines, in particular to a metal powder fuel air-water cross-medium engine and a control method thereof. Background technique [0002] The ramjet engine is a kind of air jet engine that uses the deceleration and supercharging effect of high-speed air flow to complete the supercharged combustion and thus work. It usually consists of an intake port, a combustion chamber and a nozzle. During flight, the airflow decelerates while passing through the intake port, and the static pressure increases. The pressurized air enters the combustion chamber and mixes with fuel to organize combustion. The high-temperature gas generated expands and accelerates in the nozzle and is discharged to generate thrust. [0003] The fuel specific impulse of the ramjet engine is much higher than that of the existing turbojet engine and compression ignition ramjet engine, which can achieve higher flight speed and altitu...
