Paper on rocket motors without nozzles



This article was posted at The Rocketry Planet. It is fascinating to see that rocket engines can work so well without a nozzle. Before learning about this about 2 years back, I had assumed that most of the ISP from a rocket motor came out of the converging, diverging nature of the nozzle. How can exhaust even be supersonic without a nozzle? It still blows my mind!
