The invention provides an efficient self-adaptation catalytic cracking device suitable for a regenerative cooling detonation combustion chamber. On the basis of the regeneration cooling scheme, the device comprises a bottom-layer heat exchange layer, a middle-layer catalytic cracking layer, a top-layer gas-liquid separation layer and a device fixing structure. By utilization of a radial fuel jetting port and an expansion outlet channel evenly distributed in the circumferential direction of the heat exchange layer in an interphase manner are utilized for achieving uniform heating and flowing speed reduction of fuel, and accordingly, a large amount of micromolecule gas-state fuel is generated in a middle-layer honeycomb-shaped catalytic cracking layer coated with an efficient catalyst, wherein the micromolecule gas-state fuel is excellent in detonation performance and narrow in component kind range. Through an adaptively-adjusted N-shaped baffle plate structure in the gas-liquid separation layer, fuel oil liquid drops unfavorable to detonation and combustion in products can be effectively separated and split. The device can achieve efficient fuel splitting, mixed gas-state fuel withhigh explosion performance is continuously obtained; and in addition, the device can sufficiently utilize physical and chemical heat sink of the fuel, and the cooling efficiency of the detonation combustion chamber is improved.
Description
technical field [0001] The invention relates to the field of detonation engines, in particular to a high-efficiency self-adaptive catalytic cracking device suitable for regenerative cooling of detonation combustion chambers Background technique [0002] The detonation engine is a new concept engine based on detonation combustion. In the combustion chamber, the detonation leading shock wave is directly used to compress the gas, so that the pressure and temperature of the detonable fuel rise rapidly, and then power is generated. Due to the detonation wave propagation speed It is extremely fast, making the whole combustion process close to constant volume combustion. Therefore, detonation propulsion has a higher cycle thermal efficiency than the propulsion system using traditional slow combustion combustion. In addition, detonation propulsion eliminates compressors, turbines and other components, and has the characteristics of simple structure, high thrust-to-weight ratio, and ...
