ABSTRACT:
A parachute extraction line severing apparatus comprising an extensible cutting head depending by means of a power cord from a power cord take-up assembly The cutting head includes a housing having one or more cutting devices and a viper line extending about a parachute extraction line and normally disposed in an out-of-the-way position along the interior walls of a cargo compartment. The opposite ends of the viper line are connected to and adapted to be wound about adjacent spools of a take-up reel mounted in said housing. In the event of a cargo airdrop malfunction, rotation of the spools is effective to gather the viper line into embracing relation with the extraction line to generate a reactive force drawing the cutting head and blades into engagement with the extraction line to sever the same. Once the extraction line is severed releasing the reaction force, a spring loaded spindle in the take-up assembly retracts the power cord carrying the cutting head therewith into its normal inoperative position.
