Analysis of Key Technologies and Propulsion Performance Research of TRRE Engine

The key technical difficulties and performance of the TRRE were studied. A brief introduction was conducted on the progress of the principle prototype from the Beijing Power Machinery Institute. The performance data from the flow channel design of the principle prototype and numerical simulations were utilized to assess the propulsion performance of the TRRE engine, which primitively validated its comprehensive advantages on the acceleration, cruising, mobility and other aspects. The results show that the TRRE engine can reconcile the demands of high thrust at lower Mach numbers and high specific impulse at a Mach number of 6.0 (pure scramjet mode). In a wide Mach number operating range, the TRRE engine provides the relatively wide, flexible and convenient adjustment ability in the thrust. It can satisfy the smooth relay between the high and low speed channels, illustrating the advantageous adaptability in the acceleration, maneuver flight and high Mach number cruising.
