Abstract:

This report describes the design and testing of couplings fabricated from shape-memory brass Betalloy and used for the repair of helicopter battle-damaged hydraulic lines rigid and flexible, control tubes, and drive shafts. Flameless heaters were investigated for fueled aircraft. Hydraulic rigid couplings generally exceeded the strength of the tubing. Flexible couplings were sensitive to installation. C-type couplings for nonsevered damaged tubing added to the strength significantly but were difficult to fabricate large enough to fit over the tubing without cutting the tube. Author
