Demonstration of the Thermographic Phosphor Heat-Transfer Technique as Applied to Aerodynamic Heating of External Stores

Abstract

The purpose was to design and conduct a wind tunnel test which demonstrated the feasibility of applying wind tunnel techniques to the aerodynamic heating problems encountered in the supersonic carriage of external stores. The test incorporated the thermographic phosphor paint technique on an MK-84 store attached to the left inboard pylon of a 0.05-scale model of the F- 4C. The test was made at nominal free-stream Mach numbers of 1.49, 1.76, 2.00, and 2.50; at nominal free-stream unit Reynolds numbers between 3.67 and 4.64 million/ft; and at aircraft angles of attack of zero and +4 deg. Typical heat- transfer-rate distributions and thermographic Datacolor photographs are included.
