Detachable strut structure in combustion chamber of scramjet-oblique detonation engine

A detachable strut structure in a combustion chamber of a scramjet-oblique detonation engine, comprising:

• two strut components (2), disposed in the combustion chamber;
• wherein the combustion chamber (1) defines an inlet (41) and an outlet (42), a connection between the inlet (41) and the outlet (42) is a centerline, and the two strut components (2) are mirrored and arranged on two sides of the centerline respectively;
• wherein each of the two strut components (2) comprises:
• a first surface (21), a second surface (22), and a third surface (23);
• the first surface (21) is arranged parallel to the centerline, and the second surface (22) is arranged on a side of the first surface (21) close to the inlet (41);
• an angle α is defined between the second surface (22) and the first surface (21), and the angle α is arranged facing towards the outlet (42);
• the third surface (23) is arranged on a side of the first surface (21) close to the outlet (42), an angle β is defined between the third surface (23) and an extension line of the first surface (21), and the angle β is arranged facing towards the outlet (42);
• both the angle α and the angle β are acute angles, and the angle α is less than or equal to the angle β;
• two sets of hydraulic telescopic mechanisms (41), connected to side walls of the two strut components (2), respectively;
• wherein the two sets of hydraulic telescopic mechanisms (41) are configured to control the two strut components (2) to separate and merge in a vertical direction, when the two strut components (2) are merged, an oblique shock wave is generated at the angle α of each of the two strut components (2) as gas flows towards the combustion chamber (1);
• when the two strut components (2) are separated, the first surfaces (21) of the two strut components (2) are parallel to the gas flow entering the combustion chamber (1), generating shock waves without interfering with each other, and expansion waves are generated at the angle β of the two strut components (2).
