Conceptual design of multi-cycle pulse detonation engines

The purpose of this study is to develop a method based on multi-cycle detonation results. Fully developed repetitive C-J detonation waves are produced successfully by pulse detonation engine (PDE) model with its diameter 50mm using gasoline as fuel and air as oxidizer. The structural parameters of PDE are determined, which are more similar to the actual situation. It is found that experience constant (K) is not a fixed value and it decreases with increasing of the frequency by some function. When the frequency increases to some extent, the experience constant (K) decreases flatly and tends to a fixed value of 3.90. According to the experimental function obtained, the experience constant (K) of single-cycle detonation equals to 5.35 by calculation.
