Abstract:

Experimental data were obtained to aid in the prediction of aerodynamic loads and separation-trajectory characteristics on stores under the influence of an aircraft flow field. Four types of data were obtained in the vicinity of a generalized aircraft model 1 flow field surveys, using a 40-deg cone probe, to determine the local velocity field, 2 force and moment data on four store models, 3 pressure distribution data on an ogive-cylinder model, and 4 captive-trajectory store separation data on one store model. The generalized aircraft model consisted of a swept-wingfuselage combination with rectangular, flow-through engine ducts.
