Abstract

The unique considerations associated with the application of aerothermoelastic scaling laws in the design, construction, and testing of flutter models for re-entry glide vehicles are discussed. A brief review
of the scaling laws is presented in order to re-emphasize the point that they cannot be completely satisfied for other than the case of full scale testing of flight type hardware. This is followed by a discussion of four structural concepts that have been devised to provide acceptable structures for use in the re-entry environment. These concepts are reviewed with respect to predicting the mechanism of potential aerothermoelastic problems, and establishing the possibility of relaxing some of the restrictions of the
aerothermoelastic scaling laws. It is concluded that the aerothermoelastic problem can generally be reduced to separate thermoelastic and aeroelastic problems for these structural concepts and that the testing of small scale "artificially reduced stiffness" aeroelastic models, in conjunction with "restricted purpose" heat transfer models, will yield meaningful and useful flutter data for re-entry vehicle structural approaches that presently appear feasible. The use of this type of approach in performing wind tunnel tests on a scaled model of the ASSET re-entry glide vehicle is described.
