Impulse Measurement Technology Development at the Arnold Engineering Development Center (AEDC)

Abstract

This paper discusses the development at the Arnold Engineering Development Center (AEDC) of a measurement technique to be used in continuous-flow wind tunnels to measure approximately 5-to 50-millisec-duration impulse loads on test articles. Accelerometers are used in conjunction with a cross-flexure balance to obtain force and moment measurements of impulse loads as short as approximately 5/1000-sec duration. A math model of the mechanism is developed and used to show the measurement concept is a valid scheme. Results from a laboratory demonstration of a two-component measurement system also indicate excellent agreement between impressed impulse loads and the measurements from the mechanism.
