Abstract

PURPOSE:To alleviate a vibrating load on a wind tunnel balance when a shock wave passes in starting a wind tunnel and to improve measuring accuracy, by attaching a stopper ring between a model under test, which is attached in a measuring drum, and a sting, which supports the model. CONSTITUTION:When a shock wave passes in starting a wind tunnel, a model under test 1 is fixed with a stopper ring 4. Namely, the inner diameter of the ring 4 has a coupling size with the diameter of a sting 3. The outer diameter has a coupling size with the inner diameter of the model 1. Thus, the ring 4 can be coupled into the rear end of the model 1, and the model 1 can be fixed. Therefore, a vibrating load, which is applied on a wind tunnel balance 2 can be alleviated. In the normal measurement after the shock wave is added, the ring 4 is pulled out of the model 1. Namely, the ring 4 is connected to, e.g., a wire 5. When the wire 5 is pulled from the outside, the ring 4 can be pulled out of the model 1. Therefore, it is not necessary to use a wind tunnel balance having a large capacity. The measuring accuracy can be improved.
