Lightweight Emergency Flotation System for the CH-46 Helicopter.

Abstract

Helicopters are subject to roll over and sinking within a minute of being force down in sea states of 2 or greater. Crew egress is difficult and many drownings occur. Boeing was awarded a contract to develop a lightweight, automatically deployed flotation system to remedy the situation. An innovative system was designed which employs water scoops attached to 2 floats providing substantially increased stability for negligible weight. The concept was proven in wave tank tests and by full scale float and deployment system demonstrations.
