Misalignment studies on space shuttle integrated vehicle (IA31FC)
The effects of test model element misalignments on test results were investigated. Transonic wind tunnel-573 was designed to study these misalignment effects in detail by purposely misaligning model elements a known amount. Misalignments in TWT-573 were achieved by use of special off-set spacers and mounting hardware to change, yaw, pitch and roll on various elements of a 0.004-Scale PRR Baseline space shuttle configuration model. By comparing the misalignment runs to the nominal configuration with no misalignment, relative effects of the misalignment could be seen. This data was obtained over a Mach range of .9 to 1.46 using an angle of attack sweep of minus 10 deg to plus 10 deg in 2 deg increments.
