A Gradient Technique for Determining Improved Aircraft Trajectories for Reducing Aircraft Probility of Kill to Anti-Aircraft Gun Fire.

Abstract

The problem is to develop a technique for predicting improved aircraft flight paths that simultaneously reduce the probability of the aircraft being killed by anti-aircraft gun (AAA) fire, and fly the aircraft to certain specified position and velocity vectors, both in and out of gun range. This study develops and demonstrates a gradient minimization technique called OPTAAA for solving this problem. OPTAAA utilizes the SIMFIND1 AAA attrition model, written by the Institute for Defense Analyses, as a subroutine for computing the aircraft probability of kill. OPTAAA is applied to three problems. One of the problems utilizes two-dimensional aircraft trajectories and results in a 39.7 percent reduction in probability of kill. The second and third problems utilize three-dimensional aircraft trajectories and result in a 17.7 percent and a 41.5 percent reduction, respectively, in probability of kill. (Author)
