AIRCRAFT PARACHUTE FLARE SIMULATION

Abstract

The report presents a computer program written in Fortran IV for the IBM 360 that is a simulation of the illumination on the ground during the descent of an aircraft parachute flare from ignition to burn out. The effect of air density on the velocity is taken into account by a numerical technique. The illumination on horizontal and vertical surfaces on the ground are considered. For the surface of interest the area consisting of those points having at least a certain value of illumination is computed. The program searches for the ignition altitude for which this area is maximized over the burn time, finds the ignition altitude for which the flare burns out at a chosen altitude, or simulates the descent with ignition at a chosen altitude. Atmospheric transmission is not considered in this report.
