ABOUT PAI

Physics Applications, Inc. Since its creation in 1982 PAI s primary business has been the design and fabrication of ballistic research launchers, support equipment and instrumentation. Over the years we have produced numerous single-stage gas guns, solid propellant guns and two-stage light gas guns as well as enclosed ballistic ranges and instrumentation for both government and commercial concerns...

Ballistic Ranges

Protecting the surroundings of a research launcher is a primary concern of almost almost every ballistic research facility. Enclosed ranges contain blast, impact debris and stray projectiles as well as allow instrumentation to be used near the trajectory with minimal risk of damage. Enclosed ranges can be designed to allow evacuation to levels appropriate for conducting experiments that require a ...

Up/Down Counter

Producing trigger signals, synchronized with a projectile s arrival at location(s) downrange from the muzzle of a gun, is a frequent requirement for ballistic research experiments. PAI s model UDC-100 Up/Down Counter is ideal for providing such trigger signals at any user-selected location regardless of the actual projectile velocity. As its name implies, an up/down counter counts and stores the t...

Solid Propellant Guns

Bore Diameters: 0.17 inch (4.3 mm) and up Velocity Range: 500 to 8,900 ft/s (150 to 2,700 m/s) Solid propellant (powder) guns are the most common type of ballistic research launchers. Powder guns with rifled barrels are typically used for firing conventional ordnance while smooth-bore barrels are for launching chunky , long rod, and flat plate projectiles. Features/Options High-performance launch...

Firing Expendables

In addition to the propellant to drive them research launchers require a number of different consumable items to operate. All guns require a projectile, two stage light gas guns require a compression piston and petal valve, and single stage gas guns require a pair of burst diaphragms if they have a double diaphragm breech configuration. PROJECTILES Delivering a projectile to the target intact and ...
