The Concept of a Pneumatic Parachute Rescue System for Vertical Take-Off and Landing UAVs

This publication addresses the proposed structural solution for a system, of which the conceptual essence involves a rescue parachute being ejected from an accumulator using compressed carbon dioxide. The suggested rescue system is intended for unmanned multicopter aircraft. The article presents a developed digital solid model and the results of its simulation tests. The paper also contains results of basic calculations of the pneumatic supply system energy balance and the power balance of the electric control system. It also presents the results of first in-flight tests with a simulated emergency situation and the use of a technology demonstrator in operating conditions. Simulational and experimental methods were chosen to solve the research problem
