India’s scramjet success proves hypersonic strength, but turbine complexity keeps fighter engines a tough challenge.

NASA’s X-43A, a groundbreaking hypersonic scramjet vehicle, achieved an unprecedented speed of Mach 9.6, solidifying its status as the fastest atmospheric combustion-engine air vehicle in the world.

Supersonic combustion and scramjet engine dynamics represent a frontier in aerospace propulsion, offering a pathway to ultra‐high-speed flight through the efficient combustion of fuel in a supersonic ...
