Measurements of Transient Aerogasdynamic Forces and Moments
Abstract
The examples of realization in TSNIIMASH of measurements short duration aerogasdynamic forces and moments in piston gasdynamic units U-11 and U-7, shock tube U-I 2 and vacuum chambers U-22 and U-22M are given in the present paper. The characteristic run duration in these facilities is 0,01-0,2 5, and loading measurements are carried out without consideration of inertial forces. Some methodical approaches of measuring transient aerodynamic forces and moments acted on models, hinged on aerodynamic strain-gage balances and capable to accomplish free angular oscillation (in pitch or yaw) with the large frequency in a working flow of wind tunnel, are presented too.
