A Summary Report on Store Heating Technology

Abstract

One of the problem areas associated with the supersonic carriage of external stores is concerned with temperature restrictions on critical components. Theoretical calculations were used to guide a two-phase experimental program which included both flight and wind tunnel testing. Flight heat-transfer measurements were obtained on a pylon-mounted BDU-12 at flight conditions of 40,000 ft and Mach numbers up to 2.5. The wind tunnel tests of a 1/15-scale model included both pressure and heat transfer measurements on the flight test configuration plus several others. The results are discussed in three categories; wind tunnel, flight test, and correlation of wind tunnel and flight data. This work has clearly shown the flight capability for supersonic carriage of large stores and has demonstrated some of the available technology for defining thermal environments.
