Abstract:
In view of the design requirements for the air turbine-rocket and ramjet(ATRR)engines with Mach number from 1.5 to 4.5, a variable geometry scheme of curved symmetrical inlet with cowl translation is proposed as well as its new adjustment mechanism. The overall performances and flow characteristics are studied by numerical simulation. The results show that overall performances of the axisymmetric variable-geometric inlet with curved surface compression is high, especially the flow capture ability is good, which can meet requirements of the entire operating range. In addition, the new mechanism is simple and feasible, which is beneficial to the engineering realization.
