A titanium alloy is a strong metal and, together with the new technique, could make helicopters more reliable in difficult environmental conditions, including at sea and in the desert, analysts said. Wei Dongxu, a Beijing-based military analyst, told the Global Times that a fatigue-resistant rotor could also allow a helicopter to work under higher stress, including maintaining high speeds for extended periods or lifting heavier cargo for longer distances. The anti-fatigue feature is important because rotor fatigue is not always noticeable, causing unforeseen dangers, the report said.
China recently mastered a new fatigue-resistant technology for helicopter rotors, which could greatly expand the helicopters’ capability and service time, a development which military experts said on Tuesday could be of strategic value to China’s domestic helicopter industry as the technology could be used on China’s future heavy-lift transport helicopters and attack helicopters. During the development of an unidentified helicopter, engineers at Changhe Aircraft Industry (Group) Corporation Ltd under theContinue reading
