- Abstract:
- Simple structure and high specific impulse liquid ramjet is the best engine concept of high dynamic vehicles near space. The vehicles with large flight velocity range and long flight distance near space require high performance ramjets that adopt adjustable geometric structure technology. The ramjet performance is calculated and compared with fixed and continuous adjustable structure intake and nozzle in this paper. The results show that the performance of a ramjet with continuous adjustable nozzle is much better than a ramjet with fixed structure. Improved ramjet performance from adjustable intake is much lower than improved performance from continuous adjustable nozzle.
