TRANSONIC FLUTTER STOP DEVICE

摘要

PROBLEM TO BE SOLVED: To prevent a test model from being irregularly excited to prevent occurrence of degradation in test accuracy by providing a flutter stop device which will not generate drift and variation of air flow, in a wind tunnel system provided with a flutter stop function for automatically lowering the Mach number or dynamic pressure immediately after a flutter is generated. SOLUTION: A bored plate-like flutter stop plate is disposed at a position on the downstream side of the test model, and slidably installed from both walls of a measurement chamber. An end surface of a flutter stop member without having an opening is formed of a flat wall surface member, and the end surface is so formed as to be flush with a wall surface of a wind tunnel and so as not to have irregularity in a state where the flutter stop plate is housed in both the wall surfaces of the measurement chamber.
