AFRC (Armstrong Flight Research Center) has a long history, and a lot of lessons learned, in testing hypersonic structures. This poster describes hypersonic structures, how to test them, and the methods used to develop the testing.
This paper describes the design and conduct of the strain gage load calibration ground test of the SubsoniC Research Aircraft Testbed, Gulfstream III aircraft, and the subsequent data analysis and its results. The goal of this effort was to create and validate multi-gage load equations for shear force, bending moment, and torque for two wing measurement stations. For some of the testing the aircraft was supported by three air bags in order to isolate the wing structure from extraneous load inputs through the main landing gear. Thirty-two strain gage bridges were installed on the left wing. Hydraulic loads were applied to the wing lower surface through a total of 16 load zones. Some dead weight load cases were applied to the upper wing surface using shot bags. Maximum applied loads reached 54,000 pounds.
This presentation provides the thermal testing panel discussion with an overview of the thermal test facilities at the Dryden Flight Research Center (DFRC) as well as highlights from the thermal test efforts of the past year. This presentation is a little more in-depth than the corresponding material in the center overview presentation.
