Fusée astraunotique

[Chatta]

Bonjour,

Je voudrais savoir quelle est-t-elle la pression maximale dans la chambre de combustion Dans le fusée spacial.

Merci bien

Salut ,

De 10 à 200 bars . Source Wiki : rocket engine

" Rocket engines produce thrust by the expulsion of an exhaust fluid that has been accelerated to high speed through a propelling nozzle. The fluid is usually a gas created by high pressure (150-to-2,900-pound-per-square-inch (10 to 200 bar)) combustion of solid or liquid propellants, consisting of fuel and oxidiser components, within a combustion chamber. As the gases expand through the nozzle, they are accelerated to very high (supersonic) speed, and the reaction to this pushes the engine in the opposite direction. Combustion is most frequently used for practical rockets, as high temperatures and pressures are desirable for the best performance. "
