Abstract:
According to the structure of the rolling control engine, three exhaust pipe schemes were designed for engine test. In scheme 1, a clearance between engine pipe and exhaust pipe is kept. In scheme 2, the end of the engine pipe is put into the entrance of exhaust pipe which is followed by an elbow bend pipe. In scheme 3, the end of the engine pipe was put into the entrance of exhaust pipe. The effect of the three exhaust pipes was numerically simulated by means of a commercial software. The results indicate that structure of exhaust pipe in scheme 1 is simpler and easier to implement than other schemes, and can meet the condition of exhaust drainage; the exhaust pipe in scheme 2 can result in large axial force though it also can meet the requirement of exhaust drainage; the exhaust pipe in scheme 3 can meet the requirement of exhaust drainage, but it is difficult to control the clearance between engine pipe and exhaust pipe. According to the analysis, the result that the exhaust pipe scheme 1 is suitable for the rolling control engine was obtained.
