An Inexpensive on-Line Analog Computer for a Wind Tunnel.

Abstract

An inexpensive analog computer has been developed which can be used for on-line data reduction of pitch and yaw strain-gage balance data during a wind tunnel test. This computer can be used with any size balance, the only restriction being that the multiplication constants of the computer must be tailored or adjusted to the calibration constants of the balance. The existing computer is constructed for any use with any balance having moment bridges for measuring pitch and side forces. The computer reduces the individual bridge signals to forces, transfers the moment to a selected moment center, and also computes the angular sting deflection due to the force and moment acting on the model.
