Abstract

The invention discloses a design method for an aerodynamic self-separating fairing of a ramjet inlet, which includes the following steps: S1: design and block the inlet according to the body surface design upstream of the lip of the ramjet inlet of a super / hypersonic aircraft The fairing of the air passage, the fairing includes a bottom plate, a side wall and a blocking plate; the side walls are arranged on both sides of the bottom plate, and the blocking plate is arranged at the tail end of the bottom plate; S2: in the fairing Under the incoming flow conditions during separation, conduct numerical simulation analysis on the flow field of the super / hypersonic vehicle to obtain the data of the flow field; S3: Open pressure regulating holes on the side wall; S4: Design the motor mechanism of the fairing. The invention can greatly reduce the weight and design difficulty of the fairing system; in addition, when the fairing is separated, the opening and closing of the air inlet can be realized at the same time, without blocking fragments, and avoiding additional influence on the structure of the air inlet.

Description

technical field [0001] The invention relates to a design method of a ramjet fairing, in particular to a design method of a ramjet air inlet pneumatic self-separation fairing. Background technique [0002] At present, the intake port is an important part of the jet power plant, its function is to use the speed ramming of the oncoming flow, effectively convert the kinetic energy into potential energy, increase the pressure of the air flow, and provide the required air flow for this type of engine ; In addition, the ramjet cannot work at zero speed, and must rely on the booster to enter the cruise phase to fly. In the boost phase, the flight speed is also very high. At this time, if the intake port is opened, the airflow entering the combustion chamber will generate aerodynamic heating, which will affect the internal structure. Therefore, the air intake also plays a blocking role, opening it when it should work, and closing it when it shouldn't. The opening and closing of the...
