Re-Entry Module/Adapter Interconnect Fairing Aerodynamic Heating Wind Tunnel Tests AEDC Tunnel B
Abstract
Testing was conducted on three, 9 percent scale Gemini models and a 5.8-inch diameter hemisphere cylinder to obtain qualitative and semi-quantitative information on the local heat transfer rate induced on the Gemini afterbody by the module/adapter interconnect fairing. These models were cast using RTV 60 silicone rubber. A 0.3-inch minimum thickness of rubber was maintained over an aluminum core. The Gemini models were tested at 160, 165, and 170 deg angle of attack. The hemisphere cylinder was tested at 0 deg angle of attack. Testing was conducted at Mach 8 at Reynolds numbers per foot of 3.8, 3. 5, 3.0, 2.0, and 1.0 x 10 to the 6th power. Prior to each run, models were coated with paint. Color motion pictures were made during the test to obtain color change data, and still photographs of the models were taken after each run. Forty-seven runs were completed during Series 1 tests and 27 runs during Series 2 tests.
