Abstract：A manufacturing methodology is provided for typical titanium alloy tube assemblies in 21–28MPa aeronautic hydraulic pressure system, based on tube numerical control left/right bending technology, tube optical measurement technology, tube flareless internal rolling connection technology and quality test technology of titanium alloy tube assemblies. This methodology is verified by a manufacturing process of the high strength titanium alloy (Ti–3Al–2.5V) tube assemblies for a typical hydraulic pressure system in a commercial plane. It can be found that the manufacturing precision, efficiency, and reliabilities of the titanium alloy tube assemblies are enabled by using this methodology, and a new technology way can be found for solving the leakage problems in aeronautic hydraulic pressure system.
