Abstract:
For the hypersonic aircraft with ATR/ramjet parallel combined power, its overall performance parameters are calculated and analyzed according to a typical trajectory. The results show that the acceleration of the aircraft is good during the operating phase of ATR engine, especially in the range of Mach 2.0～3.5. The total flight range increases rapidly as the thrust-weight ratio increases, while the difference of flight time is very small, in which the proportion of ATR operating phase is significantly decreased. The total flight range and flight time increase significantly with the increase of lift-drag ratio, and a sharp increment turns up when Mach number reaches up to about 6.0. The above research further deepens the understanding of ATR engine from the view of aircraft system.
