An investigation of the interference effects of a sting support system on the pressure distribution over a body of revolution

The pressure distribution over a body of revolution was measured, both with and without a sting, or sting and simulated sting-support structure, present. The investigation was carried out in a wind tunnel at a low speed. The results indicated that the changes in the pressure distribution over the body were small if the sting diameter was half the base diameter and the sting made reasonably long. The effects of the sting and sting-support structure were felt only over the aft 20 percent of the body and were such as to increase the pressure in all cases investigated.
