摘要
简要介绍脉冲爆轰技术的基本原理及其在能源、航空、航天等领域中的应用背景 ,分析了该技术中供料过程、起爆过程、防振防噪等技术难点 ,针对部分具体问题提出应在进料问题中考虑进料速度与混合效率和能量损失之间的统一性问题 ,分析了流动混合过程中起爆对缩短从爆燃到爆轰转变距离的有利和不利因素 ,指出振动和噪声等问题对脉冲爆轰技术带来的不利影响 .
The general principles and application background in energy usage, aerospace and aeronautics of pulse detonation technology are presented in this paper. Some of the technical difficulties related to the technology, such as fuel supply, ignition, vibration proof and noise proof, are discussed. The main points of view proposed by the author are as follows: 1. Speed of mixture filling up should be considered with the mixing efficiency and energy losses; 2. Ignition of detonation in flowing mixture is benefited from turbulence caused by flow, and DDT length will be increased due to the insufficient mixing; 3. Vibration and noise elimination would be vital for the application of pulse detonation technology.
