Embodiment

[0022] Embodiment: When starting, open the valve, and the compressed air with very high pressure in the air storage tank will spray high-speed airflow from multiple air nozzles towards the flame cylinder through the air delivery pipe, and the air outside the air inlet will generate a strong air flow due to the high-speed airflow. The air is quickly sucked into the intake port by the suction effect, so the two airflows make the static engine fly at high speed; the high-speed airflow enters the combustion chamber from numerous small holes in the flame tube, mixes with the mist fuel sprayed from the fuel injector, and ignites The high-temperature gas is ignited and burned, and then ejected from the tail nozzle at high speed to generate recoil thrust; the air suction effect generated by the high-speed jet sucks the air around the tail nozzle into the tail nozzle through numerous small holes, thereby increasing the injection volume. ;As the aircraft continues to accelerate, the prop...

Abstract

The invention provides a ramjet started in a static state. The ramjet started in the static state comprises a ramjet body and a starting device. The ramjet body comprises a shell, an exhaust nozzle, a flame tube, an oil spray nozzle and an igniter. The starting device comprises a high pressure gas storage tank, a valve, a gas conveying tube and a gas spray nozzle. The ramjet started in the static state has the advantages of being capable of being started in the static state, stable in combustion and lower in cost, solving the problems existing in an existing ramjet, and better keeping the original advantages.

Description

technical field [0001] The invention belongs to a heat engine, in particular to a statically started ramjet. Background technique [0002] The ramjet engine has many advantages such as simple structure, low cost, light weight, large thrust-to-weight ratio, high speed, high efficiency, less failures, and long life. However, because it cannot be started when the ground is stationary, other engines are needed as boosters , it can work effectively only after it reaches a certain flight speed, so it cannot be used alone as a power plant for ordinary aircraft, which greatly limits the scope of application, and is now only used on missiles and target aircraft. Although its combination with a turbojet engine or a turbofan engine can be used as an aeroengine, the engine that cooperates with it only works when the aircraft takes off, lands and flies at low speed, but this combined power unit loses most of the advantages of the ramjet engine. Contents of the invention [0003] The p...
