RESULTS OF INVESTIGATIONS ON A 0.004-SCALE 140C MODIFIED CONFIGURATION SPACE SHUTTLE VEHICLE ORBITER MODEL (74-0) IN THE NASA/LANGLEY RESEARCH CENTER HYPERSONIC HELIUM TUNNEL (0A109)

摘要

This report documents data obtained during a wind tunnel test of a 0.004-scale 140C Modified Configuration SSV Orbiter in the NASA/Langley Research Center 22-inch Hypersonic Helium Tunnel. The test was conducted during August 1974 with 80 occupancy hours charged. All runs were con ducted at a nominal Mach number of 20 and at Reynolds numbers of 0.7, l.0, 1.8, and 1.1 × 106 based on body length.nThe complete -140C modified model was tested with various elevon settings at angles of attack from 10 to 50 degrees at zero yaw and from angles of sideslip of -10 to +10 at 35° angle of attack.nThe purpose of this test was to obtain high hypersonic longitudinal and lateral-directional stability and control characteristics of the up dated SSV configuration.
