Investigation of the sting interference effect due to the TWG 15-degree, 25-degree and 45-degree rolling stings.

Kurzfassung

This report details a series of numerical experiments designed to provide an assessment of the acceptable sting length between the model and the sting holder required to minimise sting interference for the TWG 15-degree, 25-degree and 45-degree rolling stings. Calculations were undertaken for Mach numbers of 0.50, 0.90, 1.05 and 1.63, and for model attitudes between 0 and 55 degrees. These calculations indicated that the minimum spacing varied with the Mach number and angle of attack between 1 cm and 20 cm.
