The Application Of Stamping Parts
Ramjet stamping parts refers to the ramjet engine.
Ramjet stamping parts engine is the airflow into the engine by means of a head after the slowdown, allowing the air to improve air static pressure of a jet engine. It usually consists of the inlet (or diffuser), the combustion chamber, promoting the nozzle 3 formed. Ramjet stamping parts no compressor (also do not need gas turbine), it is also known as non-air jet engine compressor.
First introduce the principle of stamping parts. This method of compressed air engine, is by aircraft flying at high speed, the relative airflow into the engine inlet in the slowdown, the kinetic energy into pressure energy (for example, the intake rate is 3 times the speed of sound, the theory of air pressure can increase 37-fold ). Ramjet stamping parts work, high-speed airflow to the engine blowing head, slowing expansion in the inlet, pressure and temperature of the fuel entered the combustion chamber (usually kerosene) mixed combustion, the temperature increased to 2000 or even a 2200 high temperature gas then accelerated by the forward nozzle expansion, the jet exhaust and high-speed thrust. Ramjet stamping parts thrust and the speed of the intake, such as the intake rate of 3 times the speed of sound, the static thrust in the ground can produce more than 200 kN.
Again introduce the stamping parts procedures. Ramjet stamping parts simple structure, light weight, thrust to weight ratio, and low cost. But no compressor can not start in the static condition, but not for normal aircraft power plant, but often used in conjunction with other engine, a modular power unit. Such as the ramjet and rocket engine combination ramjet stamping parts and turbojet engines or turbofan engines and combination. Combined aircraft power plant installation, start at the take-off rocket engines, turbojet or turbofan engine, the flight speed to be enough to punch the time the engine work, and then closed with the use ramjet stamping parts engine with the work; the landing stage When the aircraft's flight speed reduced to stamping parts when the engine is not working properly, then restart the engine with tie. If ramjet stamping parts power plant as a vehicle when used alone, then the vehicle must be carried by other aircraft in the air and have some speed, can be run after the engine start punching. Combined ramjet stamping parts or scramjet, or supersonic missiles and are generally used for subsonic drone on.
By application divided into subsonic ramjet stamping parts, supersonic, hypersonic three.NingBo YinZhou WeiSheng is the profession production in various stamping parts,deep drawn parts,welding parts,machining parts, and metal semi-processed goods and finished product etc..
Using diffusion-shaped subsonic ramjet stamping parts inlet and convergent nozzle to aviation kerosene as fuel. Flight pressure ratio less than 1.89, flight Mach number is less than 0.5 generally does not work. Subsonic ramjet stamping parts engine used in the subsonic aircraft, such as subsonic drone.
Supersonic ramjet stamping parts with supersonic inlet (entrance of subsonic combustion air) and convergent or convergent diffusion Nozzle, aviation kerosene or hydrocarbon fuel. Supersonic ramjet stamping parts propulsion to 6 times the speed of sound for the subsonic, supersonic target aircraft and surface to air missile used.
Hypersonic ramjet stamping parts in supersonic combustion was conducted using the hydrocarbon fuel or hydrogen fuel, the flight Mach number as high as 5 to 16, currently is in a hypersonic ramjet stamping parts engine in development. As the supersonic ramjet stamping parts combustor entrance subsonic airflow, also referred to as the former two types of subsonic ramjet stamping parts engine, which will be called the third supersonic ramjet stamping parts engine.
