Abstract

The invention discloses a one-way priming device of a probing type rotation detonation engine. The one-way priming device comprises an installing base fixed to the outer wall of the rotation detonation engine, a pre-detonation pipe, a detonation pipe switching device, an installing base end cover and an elastic element, wherein the pre-detonation pipe penetrates through the installing base and is in sliding fit with the installing base, the detonation pipe switching device is used for connecting the pre-detonation pipe and an ignition pipe, the installing base end cover is arranged at the end of the installing base and limits the installing base in the sliding direction of the pre-detonation pipe, and the elastic element on the pre-detonation pipe exerts elastic force on the pre-detonation pipe in the sliding direction of the pre-detonation pipe. An opening for the pre-detonation pipe to stretch into is formed in an annular combustion chamber of the rotation detonation engine, and an opening communicated with the annular combustion chamber is formed in the side wall of the pre-detonation pipe. The rotation detonation wave engine can be detonated in one direction, and the rotating spreading situation of detonation waves in the combustion chamber in the normal working period of the engine is not affected. The restarting problem of the engine is solved, and all components are reasonable in design and high in reliability.

Description

technical field [0001] The invention belongs to the technical field of rotary detonation wave engines, in particular to a one-way detonation device for a penetrating rotary detonation engine. Background technique [0002] Nowadays, methods such as spark plugs, combustion wires, electric detonators, and installation of explosive blocks in passages or side walls are used to start rotary detonation engines. The ignition source causes wave formation with a rapid transition to a shock or detonation wave, which has a low success rate. For example, Kindracki et al. found that ignition of the methane and air mixture in the annular combustion chamber with a spark plug only had a 40% success rate. The main reason is that a detonation wave propagating in two directions is generated at the ignition point. After the two detonation waves intersect, since the front of the detonation wave is the combustion product that has just finished combustion, it cannot support the continuous propagat...
