Butler Unmanned Parachute Systems, LLC. has the experience, the personnel and the facilities to design and manufacture a wide variety of vehicle recovery systems. BUPS designs these systems with all the necessary components and equipment to successfully recover unmanned air vehicles (UAVs), target drones, and other air vehicles. We have built systems ranging from 8 inch decelerators for small sub-munitions to solid cloth canopies up to 154 feet in diameter. These systems are designed for deployment at speeds near zero and as high as Mach 2.
The following is a list of some of the most recent systems BPS has produced:
MIT/Draper Technology (WASP)
BPS designed and produced a cruciform decelerator for an unmanned, 22 lb, 4 inch diameter, surveillance vehicle. This vehicle is launched from a cannon and reaches speeds of 1100 ft/s.
Aurora Flight Sciences (Theseus UAV)
BPS designed, built and delivered a complete recovery system in 67 days. This system included a rocket deployed 47' ringslot drogue canopy and 130' main canopy. Unfortunately, the system had not yet been installed in Theseus when the aircraft suffered an in-flight structural failure.
Freeing Aerial Robotics Corporation (Scorpion UAV)
BPS designed and built a rocket deployed recovery system for 320 lb./150 kt. UAV. The parachute is packaged in a complex conformal container to maximize the pack volume available within the engine compartment and firewall area.
General Atomics Aeronautical Systems Division (Predator UAV)
BPS designed, built and tested a recovery system for an 1,900 lb. unmanned air vehicle. The system utilizes a rocket extraction system with a pilot chute to provide positive main chute deployment until full line stretch is reached. The main chute is a 70.5 ft. nominal diameter, extended skirt tri-conical canopy with drive vents to provide a modest glide ratio with minimal oscillation. A completely new test vehicle with ground and aircraft handling equipment was designed and built by BPS specifically for this program. We have written a technical paper describing this project in detail. For a copy of AIAA 95-1573 click here.
General Atomics Aeronautical Systems Division (Gnat-XP & Altus UAVs)
BPS designed and built a common recovery system for these 1,300 to 1,800 lb. UAVs. Both aircraft utilize the same parachute components but have separate conformal canisters peculiar to each aircraft type. The recovery system utilizes a rocket extracted 15.5' ringslot drogue parachute and a 47' main parachute canopy.
Meteor CAE, Italy (Mirach 100/5 Air Target)
BPS designed, developed and tested a complete recovery system for the Mirach 100/5 target drone. This is a two stage system with an 8' reefed ribbon drogue parachute (Kevlar/Nylon) and a 37' main parachute canopy. The system is designed to recover 660 lb. at Mach 0.9 at up to 15,000' MSL. BPS tested and qualified the system at up to 468 KEAS at 695 lb.
North Carolina State University (17% F/A-18E/F RPV)
BPS designed and developed a very low-cost, lightweight rocket deployed parachute system as an emergency backup for NC State's powered model of the F/A-18E/F.
3-Sigma (Greece) (Iris Air Target)
BPS designed and produced a system to replaced an unsatisfactory existing unit. This 16' reefed main canopy is deployed by a pilot chute and was designed for 125 lb. at up to 185 KIAS. The BPS system has had an excellent service history.
