The invention relates to the technical field of engines, and discloses a rotary
detonation combustion chamber capable of realizing observation of a flow field structure of an isolation section. The rotary
detonation combustion chamber mainly comprises a rotary
detonation combustion chamber body and an air inlet mixing module, and the air inlet mixing module is of a hollow interlayer structure andcomprises a radial
runway type air inlet section, a radial
runway type isolation section and a
fuel injection module; incoming air is accelerated by a
supersonic nozzle of the radial
runway type air inlet section to form supersonic
airflow, and the supersonic
airflow enters the radial runway type isolation section and is mixed with fuel to form
combustible gas; and the high-speed
combustible gas is detonated in the
combustion chamber body to form high-frequency high-pressure rotary detonation
waves, and the high-frequency high-pressure rotary detonation
waves disturb the incoming flow to forma
shock wave structure which is transmitted forwards to the radial runway type isolation section.
Optical glass is arranged on the two sides of a radial runway type isolation section runner, corresponding
optical observation equipment is arranged on the two sides of the
optical glass, an observation light path passes through an isolation section flow field through the
optical glass, and thereforeoptical observation of an isolation section flow field wave
system structure is achieved.
