【摘要】The Missile Design Personal Computer Trajectory Analysis Program (Missile Design PCTRAP) 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 main¬frame simulation models, such as TRAP for conceptual and preliminary missile design phases, trade¬off studies, academic purposes, and military operational applications.nMissile 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.
