Full envelope six-degree of freedom simulation of tactical missile

Missile performance of alternative configurations can be evaluated using a variety of methods. These include analytical estimates, computer simulations, laboratory tests, and flight tests. Analytical techniques are the simplest and less costly, it provides estimations of missile performance characteristics, such as maximum speed, operational range and time of flight, but the detailed interactions of subsystems are difficult or impossible to predict accurately. Laboratory testing provides credible information, but more costly, and restricted mainly to subsystem evaluation. The most credible means is flight testing, but it is also the costliest and time consumed. So, there is a gap, between the extremes of low-cost, low-credibility analytical methods and high-cost, high-credibility flight testing methods. The gap is filled by computer simulation. This paper describes a brief and comprehensive methods of six-degree-of-freedom computer simulation of tactical missile that can be implemented by using modern programming languages, such as C#, C/C++, or others.
