Ultrahigh-energy single-detonation ignition device with energy capable of being adjusted within wide range and control method thereof

Abstract

The invention provides an ultrahigh-energy single-detonation ignition device with the energy capable of being adjusted within a wide range and a control method thereof. The ultrahigh-energy single-detonation ignition device comprises an energy storage capacitor set, a direct-current stabilized power source, a protective resistor, a direct-current boosting module, a voltage monitoring module, an ignition relay, a discharging relay and an ignition module. After sufficient energy is stored in the energy storage capacitor set of the device, breakdown of gaps between interval-adjustable ignition needles is achieved by conducting transient discharge, and thus high-energy ignition and direct detonation of detonating combustion are achieved. Compared with a traditional high-energy ignition system, the ultrahigh-energy single-detonation ignition device is simple in structure and high in safety, the ignition energy adjustment range is wide, the highest ignition energy can reach hundreds of Joules, and the ultrahigh-energy single-detonation ignition device can be applied to the field of micro-scale and ordinary-scale detonation study.

Description

technical field [0001] The invention relates to the technical field of detonation combustion and pulse detonation engines, in particular to an ultra-high energy single detonation ignition device with adjustable energy in a wide range and a control method thereof. Background technique [0002] Pulse Detonation Engine (PDE) is a new concept engine that uses intermittent detonation waves to generate thrust. As a new type of power device, PDE has broad application prospects in both civil and military fields due to its potential advantages such as simple structure, high cycle efficiency, wide working range and high thrust-to-weight ratio. The initiation of the detonation wave is one of the keys in PDE research. [0003] At present, the initiation of the detonation wave can be achieved through direct detonation and Deflagration to Detonation Transition (DDT for short). DDT is widely used in detonation research because it can initiate a delayed combustion wave with relatively low...
