An Investigation of the Stresses in a Wind Tunnel Corner Section

摘要

This Report describes how the stresses in a wind tunnel corner section were investigated by means of a 1/6 scale model. Both the brittle coating technique and elevated temperature strain gauges were employed. Two separate tests were performed in which it was attempted to simulate the thermal stresses and the pressure stresses respectively. Methods of overcoming some interesting experimental problems are fully reported and the significance of the results obtained is discussed.
