Generic Wing, Pylon, and Moving Finned Store

Background 
A Computational Fluid Dynamics (CED) Proyam of the U. S. Air Force Laboratory (AFRL), formerly (AFATL), 
funded and supported this wind tunrwl test. data support the ongoing validation efforts for CPD uxies. A review at AEDC, 
completed Junc 12, 1996, determined the were unrestricted. 
The test met the objectives of providing preesure data from geometrically simple wing and store shapes under mutual 
interference conditions with the store both at its carriage position and at seleaed rx)ints along a realistic store separation 
trajectory. AFRL chose AEDC's 4-Foot Transonic Aerodynamic Wind Tunnel (4T) for the tÄt. AEDC's Captive Trajectory 
Support (CTS) system, a moving store-support mechanism, simulated the motion of thc store. Dr. L Liejewski, AFRL Eglin 
AFB, FL 32542, desiywd and executed the test. F. Rolland Heim, Sverdrup Tedlnolocy, MS 6001, Arnold AFB TN. 37388, an 
AEDC project conducted the experiment. 
A generic finned-store shape and a clipped delta wing with a 45-degree edge were the primary test articles. Store 
pressure data were acquired with a model with orifices al 10Gitions in 36, 10-degree intervals around the store and 
at 8 span-wise locations from 10 to 80 percent span on both surfaces of each fin. Wing upper and lower surface orifiæs at 
locations inboard, outboard, and in the plane Ofthc pylon also provided data The pylon had orifices well. These data 
requirements in mmbinalion with store sin required testing at locations on both the left and right sides of the wing 
model. However, the resultant data are from a virtual, single store releßed from the pilot's right wing. Thus, the virtual

model. fie rig was positioned such that the store model at carriage nairly touched the left or right pylons, as required to 
a trajectory, Fig 1 , Apmdix. The store fins were positioned at carriage in a rotated cruciform style and were 
such that Fin I is positioned 45 degrees ccw of the pylon looking upstream. Fin 2 is 90 degrees ccw of Fin I , and so on. 
Summary of Data
