What is it about?
Gas turbine and rocket engines operate under the Brayton Cycle. On the other hand, rotating detonation engines (RDEs) employ a continuous volume combustion process to achieve Pressure Gain Combustion (PGC). Recently, there has been an interest in improving different aspects of RDEs such as performance, combustion stability and new materials that are able to withstand the operating conditions of detonation engines. This study focuses on the inner body configuration of the RDE, investigating the effects of adding a hump on detonation stability and overall performance of the engine.

Why is it important?
We use a small scale RDE to analyze the effect of the variation of the inner body in the overall performance of the engine. This is important for better understand the performance of smaller engines and in order to understand how combustion stability is affected by changes in the geometry.
Perspectives
This article allowed me to better understand the RDE which is a very interesting technology that has been studied for many years. The detonation engines will be the technology implemented in the future since its performance surpass the Brayton cycle engines.
