The performance is presented, and a description is given, of a simple pressure-gain combustor, without moving parts, which has been shown, during laboratory trials, to produce a stagnation pressure-gain across the combustor in excess of 5 percent at a combustor stagnation temperature of 3:1. It is also shown that the concept of the device appears to lend itself to development in such a way that it should be possible to incorporate successfully combustors based on the prototype in many gas turbines.
