Methods and a system for simulating a weapon system are provided. The weapon system may be modeled using a detailed-error-source description (DESD), with an error term for each error source in the weapon system. A target for the weapon system may be determined. For each simulated shot, each error term in the DESD may be perturbed using a Monte Carlo technique and an impact location of the simulated shot determined. The perturbation of each error term, additional system parameters, and the impact location of each simulated shot may be stored in a system-state data structure. A performance result of the weapon system may be determined. After firing all simulated shots, analysis of the system-state data structure may be performed. Performance results and/or an error-weighting function of the weapon system may be determined based on the analysis.

Method and apparatus for analysis of errors, accuracy, and precision of guns and direct and indirect fire control mechanisms

An isolation system for a sensitive component or apparatus affixed to a mortar tube comprising a barrel mount assembly which supports two parallel shafts. A plate parallel with each axis of the two shafts positions four bearing carrier blocks, two each containing a sleeve bearing which rides on each of the shafts to allow the plate assembly to slide freely along the length of the shafts and support an isolated cage. During firing, the travel vector is decoupled from the cage by the shafts as they move with the barrel through the bearings leaving the cage assembly in free space. The cage then accelerates under the force of gravity over the distance of the displaced travel of the shafts back to its rest position landing on steel springs or dampers, each on a shaft and seated against the lower flange end of the barrel mount assembly.

Pointing device inertial isolation and alignment mounting system

A system for precisely measuring muzzle exit velocity of a 'muzzle loaded' mortar projectile fired from a mortar tube using two back-biased Hall effect sensors for projectile gas ring channel detection. The system includes a back-biased Hall effect sensor block, a digital resolver electronic circuit and a computer software interface. The back-biased Hall effect sensors are located in a calibrated sensor block attached to a mortar tube. As the projectile metal casing passes a face of the sensors, the sensors trigger and release, providing two electronic pulses. The pulse edges are captured in the resolver electronics, containing a discriminator circuit for filtering all input pulses to distinguish between a projectile loading event and a projectile firing event. Once a valid firing event is detected, an output of precision timers is presented serially to a computer where it is processed and displayed by a computer software interface.
