Missile Design PC Trap: An Improved PC Trap for Tactical Missile Design

摘要

The Missile Design Personal Computer Trajectory Analysis Program (Missile DesignPCTRAP) is a simple and compact multi-purpose tactical missile simulation program that runs quickly on any IBM-compatible personal computer. It is an improved version of the USAF PC TRAP computer program, in that it adds guidance laws, simulates two extra intercept scenarios (surface-to-air and air-to-surface), and provides more simulation options, such as flight envelope generation and Monte Carlo simulations. Missile Design PC TRAP is proposed as a substitute for complex mainframe simulation models, such as TRAP for conceptual and preliminary missile design phases, tradeoff studies, academic purposes, and military operational applications. Missile Design PC TRAP can simulate the launch aircraft, the target and the missile in three-dimensions as point mass vehicles in air-to-air, surface-to-air, or air-to-surface intercept scenarios. Real time graphics display of the vehicle trajectories is available. Seven tactical missile guidance laws are derived, detailed and implemented into the Missile Design PC TRAP algorithms. The missile aerodynamic, propulsion, and physical characteristics are estimated from a small amount of input data. The program can simulate one-on-one engagements, generate launch envelopes in two planes, and perform Monte Carlo simulations with random initiation of the selected target evasive maneuvers. Its computing time is generally less than real time on a 486 33Mhz personal computer chip.
