External Store Airloads Prediction Technique. Volume 2. Detailed Data. Book 3. MER Carriage Side Force and Yawing Moment Predictions

The technique for predicting the airloads of a store carried on a multiple ejector rack (MER) is presented in this section. The approach consists of inserting the MER/store configuration into the flow-field of the base wing (45 sweep) as outlined in Subsection 2.3 to obtain an initial prediction for the side force, yawing moment, normal force, and pitching moment components for the two rack centerline stations (MER stations 1, 2). The MER shoulder stores are treated as increments to be added to the initial predictions made for MER stations 1 and 2 for these four components. The rolling moment and axial force components are predicted in a manner similar to that used for the single carriage predictions. See also Volume 2, Book 4, ADB019640.
