Investigation of the Flow Field Beneath the Wing of the F-4C Aircraft with Various External Stores at Mach Number 0.85
Abstract
Tests were conducted to measure the velocity vector components in the flow field beneath the wing of the F-4C aircraft at Mach number 0.85. A conical- tip pressure probe was used to measure the velocity vectors beneath the wing with configuration combinations of pylons, Triple Ejection Rack (TER), Multiple Ejection Rack (MER), M-117, MK-81, and MK-84 stores. Results of the test indicate that the severity of the upwash and sidewash flow increased with the addition of pylons, TER, MER, and stores. The M-117 stores on the TER and MER produced the most severe flow field distortions. Also, the longitudinal gradients o upwash and sidewash flow decreased with an increase in aircraft angle of attack.
