Hypersonic propulsion is a field of research that focuses on developing engines and propulsion systems capable of achieving speeds greater than Mach 5, or five times the speed of sound. This technology is of interest in aerospace engineering for applications such as military aircraft, space launch vehicles, and missiles, as it offers the potential for faster travel times and greater efficiency. Hypersonic propulsion typically involves utilizing advanced propulsion concepts such as scramjet engines, which rely on supersonic combustion of air to generate thrust. Researchers in this field are working to overcome challenges such as high temperatures, aerodynamic heating, and structural integrity at hypersonic speeds in order to make hypersonic flight a practical and reliable technology.
