Background
A turbo-based combined cycle engine (TBCC) is regarded as the most promising hypersonic aircraft power device at the present stage as an air-breathing engine with the performance advantages of wide flight range, conventional take-off and landing, reusability and the like. The low temperature of the incoming flow and the excessive local flow velocity inside the TBCC multi-mode combustion chamber cause the flow conditions of low temperature and excessive local flow velocity to bring difficulties for ignition and flame stabilization inside the multi-bypass combustion chamber due to the characteristic that the bypass ratio is greatly changed in the whole working range.
With the increase of the air flow velocity in the modern high-performance afterburner, in order to ensure the reliable ignition performance of the combustor, an on-duty flame stabilizer is generally adopted for soft ignition at the outer ring of the combustor, and a radial flame stabilizer is combined to improve the flame propagation capacity, so that a concave cavity/support plate combined flame stabilizer is formed. However, the radial flame stabilizer blocks the flow channel to increase the flow speed in the flame stabilizer on duty, and meanwhile, the low-speed backflow area formed behind the radial stabilizer can also absorb the flow in the flame stabilizer on duty and damage the flow form in the flame stabilizer on duty, thereby deteriorating the ignition performance on duty and the flame stabilization capability of the combustion chamber.
Meanwhile, the combined flame stabilizer is directly applied to the multi-duct combustion chamber, and the performance of the combined flame stabilizer is bound to the harsh flow conditions of the multi-duct combustion chamber. The requirements of low temperature and high speed conditions in the multi-duct combustion chamber on ignition and flame stabilization far exceed the technical level of the existing afterburner and sub-combustion ramjet combustion chamber. Therefore, the bowl/strut flame stabilizer needs to have wider lean ignition performance and lean extinction performance to meet the use requirement of the multi-bypass combustor with large variation of the incoming flow conditions in the whole working envelope.
