Pulse Detonation Engine: Parameters Affecting Performance

D Mahaboob Valli , DR. TK Jindal

Pulse detonation engine technology has recently emerged as a future aerospace propulsion technology. In this paper we studied various parameters affecting the performance of Pulse detonation engine (PDE) like pulse detonation engine Tube diameter (combustion tube), Pulse tube length for proper deflagration to detonation transition (DDT),Cell size, Equivalence ratio of fuel used . The Structural aspects like materials for fabrication of pulse detonation engine which can withstand very high pressures, temperature, yield stress and toughness is analysed. We discussed various techniques for reducing the length of pulse tube by using various DDT enhancing devices like Shchelkin spiral, grooved metal sleeves, slotted sleeves etc.
