AI Technical Summary

Technical Problem

Existing load release systems for aerial delivery face issues such as instability and tipping due to 'opening shock' during parachute deployment, leading to potential detachment or improper landing of payloads, and existing mechanical solutions add mass, require complex assembly, and are costly.

Method used

An energy dissipation and alignment device comprising rigid straps and metal rings forming a rectangular structure, which guides suspension slings to converge towards the center of the load, absorbing and redistributing tension forces to maintain stability and control the deployment process.

Benefits of technology

The device stabilizes the load by evenly distributing tension forces, reducing uncontrolled oscillations and ensuring a smooth, controlled descent by channeling slings into a pyramidal cone, thus preventing instability and ensuring safe landing.

Abstract

The present invention relates to a system (1) for the air delivery of a load (2) comprising an article (4) fastened to a platform. The load is connected to a stabilizer (7) by suspension slings (6) which attach to the stabilizer at a connection point (15). An energy dissipation and alignment device (16) is provided to stabilize the load during dropping. This device comprises rigid straps (17) and metal rings (18) forming a rectangular structure. The device (16) slides along the slings between a first position on the article and a second position above the article. It makes it possible to guide the slings toward a throttle point (23) and to make them converge to form a suspension cone (24) toward the connection point (15) for the stabilizer (7). The stabilizer may be a cluster (8) of parachutes whose connection point (15) groups the slings together and connects them to the parachutes (9).
