F/A-18 IFOSTP Fatigue Test Airbag Load Determination on the Vertical and Horizontal Tails.

Abstract

A simplistic method for determining discrete loads to approximate a distributed load is shown to have a number of deficiencies, both theoretically and in its practical results. A new method which utilizes Lagrange multipliers is derived and applied to an aerodynamic pressure distribution with improved results. The concept of weighting functions is introduced as a means of comparing the different methods in absolute terms. Weighting functions are also used to assess the effect of removing a load actuator from the standard configuration. (AN)
