Pneumatic UAV resque system

The design of an aerial vehicle requires careful attention to the issue of safety. Certainly, if possible, all systems should have redundancy and the aircraft should be able to land in case of component failure. However, this is not always possible and large drones require the installation of a rescue system. Often it is a parachute that is able to land the aircraft at a safe enough landing speed to keep the aircraft safe and secure an object close to where it is flying. Most of these systems are activated by an explosion, as it is a reliable and lightweight design. The specifics of some objects that drones fly around do not allow the deployment of such systems for security reasons.

We see the necessity of proposing a module for rescue system with pneumatic actuation. The main disadvantage of such system may be its heavy weight, however the proposed system is not heavier than analogues which use explosion.

The developed system is a module that is mounted on the aircraft with a parachute and a compressed air pool. In case of emergency, a specially designed valve pushes the parachute a considerable distance from the aircraft in a short period of time to prevent it from getting trapped in the elements of the aircraft.

Parachute system

Technical decription

Resque module

The system is designed for an aircraft weight up to 10 kg, and has an assembly weight of 500g. The parachute can unfold fully from a height of at least 6 meters, and provide a descent speed of 5 m/s. The parachute can be deployed at an airplane speed of no more than 180 km/h.
