![]() This phenomenon involves the incoming air ramming into the intake, where it is decelerated to subsonic speeds before entering the engine's combustion chambers. The air intake design plays a significant role in this.Īn air intake's primary function is to capture the air for the engine and slow it down from the flight speed to a velocity suitable for the engine combustion process, all the while avoiding shockwave-associated energy losses.ĭue to the nature of supersonic flow, a phenomenon known as 'ram effect' or ram compression can be leveraged. However, for a jet engine to be efficient at high speeds (including supersonic), understanding supersonic flow becomes crucial. The subsequent action propels the engine, and consequently, the aircraft forward. A jet engine intakes air, compresses it, ignites it with fuel to generate a forceful thrust with high-velocity hot exhaust gases. Jet engines work on the principle of Newton's third law of motion: for every action, there is an equal and opposite reaction. One of the most notable applications of supersonic flow principles is in the design and function of jet engines, especially for military aircraft and space exploration vehicles. Supersonic Flow Example: Jet Engines and Aircraft Design Various mathematical models and computer simulations can be employed to study these aspects, with a prevalent tool being Computational Fluid Dynamics (CFD).
