We are excited to announce the new Raven On-Landing Parachute Release (ROPR), a patent pending device that allows a parachute to be automatically released from a payload upon landing. This mitigates potential damage caused by wind that could otherwise drag a valuable payload after landing. Unlike other on-landing release devices, the Raven On-Landing Parachute Release is designed specifically for UAV and rocketry use and is lightweight, compact, and easy to use.
In order to work reliably, the ROPR has an internal hold timer that assures the parachute will not be released early after initial deployment due to opening bounce or other deployment shocks. The hold timer locks the device while the parachute is opening and unstable. After being under chute in steady descent for between 4 to 6 seconds, the hold timer rotates to allow for release only after landing - when the pull of the parachute unloads. Under no conditions can the parachute release early as long as the main parachute is open and the ROPR remains under load.
This type of device has many applications for situations where having the parachute detach after landing is a huge benefit, such as landing drones, rockets and other UAS. Additional uses include (but are not limited to) water drop payloads such as sonobuoys - where the payload needs to detach after splashdown - and airdrop cargo systems. For people undergoing ASTM flight testing, the ROPR can minimize damage from multiple test flights where wind conditions can damage the drone being tested.
“I’ve personally seen, after landing in windy conditions, valuable high-power rockets get dragged for miles and take on heavy damage,” said CEO Gene Engelgau. “One time, we had to drive to chase a rocket being dragged, and my son had to tackle the rocket to stop it. I designed the Raven device with the intention of helping others prevent this high-stress situation.” Gene also noted that rockets are more durable than drones and, regardless, take a lot of damage. Drones, being more expensive and fragile, would face even more damage. The Raven On-Landing Parachute Release can save a company’s valuable investments. We expect the Raven to find its way into many drone applications and other uses.
