Selective Rotor Blade Severing Apparatus.
Abstract
The patent application relates to an emergency rotor blade disconnect system for at least two paris of opposing helicopter rotor blades. A plurality of parallel wires are embedded in each blade and electrically connected to an explosive squib-actuated rotor blade severing means at the rotor hub. Breakage of one of the rotor blades along its length initiates an electrical circuit to disconnect the remaining portion thereof from the rotor hub, and also to disconnect the blade opposite to said one blade in order to maintain rotor balance and avoid excessive rotor vibration.
