UAV Catapult Launcher

Scorpion Launcher

Portable drone catapult launcher

ElevonX Scorpion drone launcher

The ElevonX Scorpion is an elastic-powered UAV launcher that can be transported and set up by a single operator. Designed from the ground up with safety, durability and ease of use in mind, the catapult provides redundant safety features and can undertake hundreds of launches with only minimal maintenance. All elastic is enclosed within the launcher tube to eliminate risk to operator or equipment in case of band failure.

The system has been constructed from industrial-grade CNC-machined aluminium and stainless-steel components, with a marine-grade pulley system as well as powder coating for increased protection. The carriage and foldable arms have been designed as standard to support our SkyEye modular UAV system, but we can modify the system to support your unmanned aircraft, even providing a custom-machined adapter to connect the UAV to the carriage.

Scorpion drone launcherThe Scorpion launcher is provided with a checklist, “remove before launch” tags and a comprehensive user guide. We can also deliver operation and maintenance training to give users all the knowledge they need to confidently operate the system.

Drone Parachute Systems

Guardian Parachutes

High-grade drone parachute system for safety and recovery 

The Guardian family of parachute systems has been specially designed both for UAV recovery and as a safety system that can be deployed under extreme flight conditions such as stalling, diving and inverted flight.

Hand-sewn from high-grade parachute materials, the parachutes feature a toroidal design that offers the best compromise between packed volume and parachute drag coefficient, providing a safe and low-impact landing for your drones and onboard payloads. The system has been thoroughly tested on our SkyEye WE 5.0 UAV prototype.

Each complete package consists of the following components:

  • ElevonX Guardian parachute (size depends on UAV maximum take-off weight)
  • Parachute deployment bag (customizable to suit your UAV parachute bay)
  • Large pilot chute for reliable deployment
  • Two-stage soft parachute opening system that minimizes stress on the UAV airframe
  • Shock chord
  • 4-point harness for stable descent and distributed load during the parachute deployment phase
  • Quick links
