Additive Manufacturing Rocket Nozzles with Cold Spray
Rocket nozzles are the propulsion nozzles (usually de Laval nozzles) in rocket engines. These nozzles increase the exit speed as well as the internal pressure of the combustion chambers and thus improve the thrust and the combustion process of the rocket engine.
As a result, rocket nozzles are exposed to severe demands. The conventional manufacture of the nozzles is tedious and costly.
With the help of the Impact Spray System, rocket nozzles can be produced in a very short time using cold spraying.
