Sensor accuracy requirements for the measurements of the forces and moments on nosetips
Abstract
The reentry vehicle aerodynamic perturbations which result from nosetip asymmetric ablation and blunting and the analytic modeling of these phenomena are reviewed. A nosetip force/moment balance system is described which has been successfully employed on several recent reentry system research and development programs to obtain in-flight measurements of the perturbing nosetip forces and moments. Also described is the use of the analytic models in conjunction with the vehicle performance and design requirements to establish the nosetip balance measurement range and accuracy levels. Based upon experience with this system, comments are offered regarding the design and use of future metric (instrumented) nosetip systems.
