The Effects of Aircraft Dynamics and Pilot Performance on Tactical Weapon Delivery Accuracy,

Abstract

An adequate model of piloted weapon delivery is needed in order to relate pilot tracking performance, and the aircraft dynamics which limit that performance, to the overall accuracy of tactical weapon delivery. By modeling the entire pilot-aircraft system for the air-to-ground weapon delivery task, an understanding of the interaction and relative importance of the various elements of the system can be obtained. With this insight the designer is able to treat the correction or improvement of system deficiencies in a logical order of their importance to a specific measure of system performance. A complete model of the piloted weapon delivery task is now possible through the application of mathematical models of the human operator's performance characteristics to the dynamic description of the combined control-display-vehicle system. The approach taken is to derive a linear expression for projectile impact error in terms of the task variables which are directly under the pilot's control. A statistical model of the propagation of these pilot-induced errors into impact error is then developed by considering each of the pilot inputs to be a random variable. A method for including the effect of pilot compensation of an observed error in one of the variables with an intentional deviation in another is also introduced. An analytical model of the human pilot is used to estimate the tracking error from the controlled-element dynamics and the turbulence environment. (Author)
