An IR source and method for generating IR radiation whereby a propellant is urned in a first chamber to produce a product gas which is exited through a critical exit, is accelerated to a supersonic velocity by expanding into a second chamber, is passed through a standing shock wave in the chamber to reduce the gas velocity to a subsonic level, is exited through radial orifices into a larger third chamber where the gas is mixed to obtain a substantial uniformity in temperature and specie, is accelerated by expansion to a chosen subsonic velocity, and is exhausted to the atmosphere.
