PULSE DETONATION COMBUSTION CHAMBER HAVING DETONATION GAS ENERGY DISTRIBUTION SMOOTH STRUCTURE

摘要

A pulse detonation combustion chamber (12) having a detonation gas energy distribution smooth structure. The pulse detonation combustion chamber comprises a combustion chamber air inlet channel (1), the pulse detonation combustion chamber (12), a pulse detonation fuel gas energy distribution adjusting device (15), and a transition section (17) which are sequentially communicated. An air inlet cone (2) is mounted in the combustion chamber air inlet channel (1); an atomized air channel (5), a fuel channel (6), and a conical swirl nozzle (11) are provided in the air inlet cone (2); the atomized air channel (5) is connected to a high-pressure atomized air inlet pipeline (3) extending into the air inlet cone (2) from the outside of the combustion chamber air inlet channel (1), and the fuel channel (6) is connected to a fuel supply pipeline (4) extending into the air inlet cone (2) from the outside of the combustion chamber air inlet channel (1); the conical swirl nozzle (11) is connected to the atomized air channel (5) and the fuel channel (6), and a pneumatic valve (8) is mounted at the tail end of the air inlet cone (2); a spark plug mounting base (14) is provided on the pulse detonation combustion chamber (12), and a spark plug (13) is mounted on the spark plug mounting base (14). The pulse detonation combustion chamber (12) solves the problems that pulse detonation combustion high-temperature gas energy flow density is concentrated, the detonation gas energy conversion and extraction efficiency of a turbine is low, and detonation combustion wave pressure is transmitted back.
