Influence of the guiding vanes on the direction of the flow behind the rotating detonation chamber.

What is it about?

It is desirable to be able to influence flow direction behind the combustion chamber in the jet engine, without any device being actually in this hot flow. In our work we focus on achieving this in so called Rotating Detonation Engine (RDE) that uses a new type of combustion chamber - detonation chamber.

Why is it important?

Being able to influence the direction of the flow downstream of the detonation chamber using a device position upstream of it has several advantages. One is the possibility to ged rid of the stator vanes of the first stage of the turbine. This in turn reduces the ovarall weight of the engine which is of the utmost importance in the filed of aircraft engines. Also, placing the device in the, so-called, colld stream allows the usage of ratating vanes to influence the flow direction even more. This leads to a better performance of the turbine and subsequently the whole engine.
