A Ventral Diverterless High Offset S-shaped Inlet at Transonic Speeds

An investigation on the ventral diverterless high offset S-shaped inlet is carried out at Mach numbers from 0.600 to 1.534,angles of attack from -4° to 9.4°,and yaw angles from 0° to 8°.Results indicate:(1) a large region of low total pressure exists at the lower part of the inlet exit caused by the counter-rotating vortices in the S-shaped duct;(2) the performances of the inlet at Mach number 1.000roach almost the highest,so the propulsion system could work efficiently in terms of aerodynamics;(3) the total pressure recovery increases slowly at first and then remains unvaried as the Mach number rises from 0.6 to 1.0,however,it does in an opposite manner in the conventional diverter-equipped S-shaped inlet;(4) the performances of the inlet are generally insensitive to angles of attack from -4° to 9.4° and yaw angles from 0° to 8° at Mach number 0.850,and angles of attack from -2° to 6~ and yaw angles from 0° to 5° at Mach number 1.534.
