The report covers an investigation of the possibility of using scale modeling to simulate environmental stresses on a space vehicle. General scaling laws were derived for simulating solar and planetary radiation, reaction jets impinging on a vehicle surface and mechanical vibration. Distortions in the simulated environment such as those produced by imperfect radiation sources, residual test chamber gas and the near presence of chamber walls were evaluated relative to induced measurement errors. Thermal simulation and mechanical vibration experiments are described which were designed to demonstrate the utility of the derived techniques. Author
