Raven On-Landing Parachute Release

Product Overview

The Raven On-Landing Parachute Release (ROPR) is a patent pending device that allows a parachute to be automatically released from a payload upon landing. This mitigates possible 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.

For people undergoing ASTM flight testing, the ROPR minimizes damage from multiple test flights where wind conditions can damage the drone being tested.

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.

How it Works

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 3 to 6 seconds, the hold timer rotates to allow for release only after the 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.

Maintenance

The ROPR is entirely mechanical and can be packed and stowed indefinitely with the parachute. Aside from keeping the ROPR clean, no maintenance is required.
