Computational aerodynamic study of body-intake configurations

Aerodynamic study over body-intake configurations has been carried out using a CFD code, PARAS. Body -Twin Intake and Body-Cruciform Intake configurations were studied. The air-intakes are two-dimensional. Computations were carried out for Mach numbers 2.0 and 3.0, angle of incidence from -10° to +10° and roll angles 0° and 45°. Computations with and without flow through the intakes were carried out. The CFD results were compared with the experimental data and the agreement is found to be good. The effect of flow through intakes on normal force and pitching moment is not significant where the effect is significant on axial force.
