Sometimes losing all your expensive electronics on your UAV is not an option. Never a 100% failsafe option (due to the infinite number of possible failures) the implementation of a parachute recovery system is one way to save the airframe and onboard components if there is an in-flight emergency. We have designed two basic types for both active and passive deployment.
Aero Telemetry has provided several different types and styles of Parachute Recovery Systems that have been implemented on many different unmanned air vehicle projects.
RECOVERY PARACHUTE SYSTEMS
Aero Telemetry designs and manufactures flight termination and vehicle recovery parachute systems for many applications. The Cross-X Series™ of high-speed canopies are Commercial Off The Shelf stock items.
Round Canopy for Air Vehicle Recovery
Drogue Chute- Active/Passive
Ballistic Deployment Devices
Pyrotechnic Timing Devices Cross-X Series™ High Speed Flight Termination Parachute Systems
HIGH SPEED FLIGHT TERMINATION
THE CROSS-X SERIES™ PARACHUTES CAN SAVE A PLANE IF:
Onboard battery fails (fail safe mode fire)
Uplink Radio interference (fail safe mode fire)
Control surface mechanical failure
Engine failure away from field
Control surface servo failure
Control loss from stalls or spins
Can be deployed without the use of ballistics and at slow speed
Can be programmed into fail safe mode in case of control loss
Active drogue chute is spring loaded
Pyrotechnic timing devices available
Pyrotechnic cutting devices available

FLIGHT TERMINATION PARACHUTES
For payloads from 20 - 50 lbs. Assembled 10' main parachute, suspension lines, riser and soft pouch pack.
The Cross-X Series™ main canopy is constructed out o F-111 Nylon or "Zero-P" material. Other materials available upon request.
For payloads to 100 lbs. Assembled 12' main parachute, suspension lines, riser and soft pouch pack. Note: For maximum effort applications, where space is not as critical, the 16P+ offers the lowest "feet per second" descent rate when used with payloads less than 100 lbs.
The Cross-X Series™ canopy is constructed out of F-111 Nylon or "Zero-P" material. Other materials available upon request.
For payloads to 130 lbs. Zero-P and Kevlar reinforced. Assembled 16' Main Parachute, suspension lines, riser and soft pouch pack. Note: For maximum effort applications, the 16P+ offers the lowest "feet per second" descent rate when used with payloads less than 100 lbs.
The Cross-X Series™ main canopy is constructed out of F-111 Nylon or "Zero-P" material. Other materials available upon request.
For payloads to 200 lbs. Zero-P and Kevlar reinforced. Assembled 20' Main Parachute, suspension lines, riser and soft pouch pack.
The main canopy is constructed out of F-111 Nylon or "Zero-P" material.
SLOW SPEED VEHICLE
115 FOOT ROUND CANOPY RECOVERY PARACHUTE SYSTEM
Vehicle recovery, slow speed deployment, round canopy parachute. Assembled 15' Main Parachute, deployment bag, risers, french links, & drogue chute.
ACTIVE DROGUE CHUTE
Active Drogue Chute with riser and internal coil spring for fastest deployment.
PASSIVE DROGUE CHUTE
Drogue Chute performance is critical to main canopy deployment. Passive Drogue Chute, riser and french links are included as optional items on all of the main canopies listed in this catalog.
