Butler Parachute Systems has the capability to test parachutes and recovery systems from sub-munitions size up to approximately 4,000 lb. at speeds up to 850 knots. We have established working relationships with several companies that provide aircraft support for various test program requirements. Available aircraft include Cessna 182, CASA 212, DeHavilland DHC-6 Twin Otter, Beech King Air B90, Lockheed T33, SAAB Draken, AerMacchi 326, F-4 Phantom II, and others. We normally use the drop zone facilities of various existing parachute centers, but on occasion make arrangements for other areas.
We occasionally drop test items from high altitudes and allow them to freefall before beginning the recovery process using timers or altitude sensors. In order to do this from unpressurized aircraft, we maintain oxygen equipment for aircrew and jumpmaster use for high-altitude drops (above 15,000 feet MSL). We also have qualified personnel available for flight crew.
