Abstract

The purpose of having dynamically adaptive load stand capability is to verify and monitor control section actuator performance under simulated free-flight aerodynamic load conditions in a Closed Loop Real Time HWIL environment. HWIL testing is a cost effective and risk reducing means of evaluating missile system prior to flight testing. This article develops methods of designing, analyzing, and testing of an extension spring driven load stand. Load stand spring natural and surging frequencies are evaluated. Nonlinear control section actuator anomalies are discussed in terms of load stand testing. Actuator time response data is examined under hinge moment and normal force loaded conditions. A design verification procedure was executed to provide a high degree of assurance that the load stand would perform as predicted by analytical methods.
