Tungsten alloy nozzle is tungsten alloy pipe used to increase the airflow rate. It is also an important part of rocket engine. It is the outlet of the gas in combustion chamber under high temperature and high pressure. It is an important component of energy conversion of rocket engine, which directly affects the performance of engine.
In the rocket engine, the flow of gas is controlled through the size of the throat area of the nozzle, so that the gas in the combustion chamber is kept at a predetermined pressure, and the charge is guaranteed to be burned normally. The propellant combustion product is accelerated through expansion of the nozzle, and its heat energy is fully converted into the kinetic energy of gas, so that the engine can obtain propulsion power-thrust. In the missile engine, the size and direction of thrust are adjusted and controlled through the nozzle.
