摘要
Abstract
Based on the multi-cycle air-breathing pulse detonation engine experiments,realtime pressure data from 9 positions along the detonation combustor axial have been obtained.After analysis of the data from time domain and frequency domain,curved surfaces of pressure with axial location and time of a cycle working in 6 frequencies have been fitted by using MATLAB software GRIDDATA function.Analyzing the fitted data from different perspectives,we find that using DDT initiation will generate a local high-pressure region before the detonation wave,after the detonation wave generation the average speed of detonation wave maintained at about 1000m/s,and its peak pressure and randomness increase.The experimental conclusions provide a foundation to study the structure and strength of the detonation combustor.关键词
