Drag and pressure recovery characteristics of auxiliary air inlets at subsonic speeds

86002 C-2003 发布历史

ESDU 86002 provides methods for estimating the drag and pressure recovery of intakes partially or wholly immersed in the boundary layer. The methods@ which are semi-empirical@ apply to circular@ semi-circular or rectangular scoop intakes@ with or without boundary layer diverter@ and flush rectangular intakes having a shallow entrance ramp of rectangular or NACA curved-divergent planform. The effect of throat just aft of the lip is derived from theoretical calculations taking account of the velocity profile. Empirical methods@ based on a limited database@ predicted spillage drag and@ for scoop intakes@ the contribution from profile drag.
