A Methodology for Determining the Survivability of Fixed-Wing Aircraft Against Small Arms
Abstract
The purpose of this study was to develop an efficient and effective method of evaluating the survivability of a fixed-wing aircraft against small arms. A computer model was created to predict the probability an aircraft survives given an encounter with a small arms weapon, P(s/e), adn the expected number of hits it receives, E(hits). The model was a one-on-one deterministic duel of a small arms weapon and an aircraft. The aircraft was represented on a straight and level flight approaching the weapon at a given velocity, angle, distance, and altitude. The small arms weapon was located at a fixed position, firing at fixed point in front of the aircraft. The weapon orientation varied by normal distributions around the fixed aim point. The bullet trajectories and represented using an interactive technique. Bullet and aircraft intersections wer calculated using a sphere to represent the aircraft. All probability distributions were broken into discrete intervals providing the means to maintaining a deterministic model. The results of the model supplied a probability of survival and expected hits for a specific weapon and aircraft with a set velocity, distance away, altitude, and angle of approach. Theses.
