The Delhi startup, incubated at IIT Madras, is developing an engine that burns fuel through continuous detonation instead of a steady flame.
A jet engine works by burning fuel in a steady flame and pushing the hot gas out of the back.
A rotating detonation engine does something different.
Fuel is detonated rather than burned, and the detonation wave travels continuously around a ring-shaped chamber.
The approach promises more thrust from a smaller, mechanically simpler engine, and it has been studied for decades without reaching routine service anywhere.
