    FAA requires inspections of PW4000 low-pressure turbines


    The Federal Aviation Administration is requiring airlines to inspect and replace “air sealing ring” assemblies within Pratt & Whitney PW4000 low-pressure turbine [LPT] cases.

  • ASCEND powertrain title-c-Airbus

    Airbus explores cryogenic superconducting powertrain for electric thrust


    Airbus has embarked on a programme to build a powertrain demonstrator showing the potential of cryogenically-cooled superconducting materials to reduce weight and improve the efficiency of power conversion for electric propulsion. Electric propulsion prospects have focused on light and regional aircraft because the power demanded for larger, longer-range types ...

  • Fresson-c-CAeS

    Project Fresson changes track in shift to hydrogen fuel cells


    A UK initiative to develop a retrofitable green propulsion system for the Britten-Noman BN-2 Islander has dramatically switched course, abandoning a previous drive towards hybrid-electric power in favour of hydrogen fuel cells.

  • UltraFan-c-Rolls-Royce

    Ground-test UltraFan demonstrator to be ready by year-end


    Rolls-Royce has formally commenced construction of the UltraFan high-bypass engine, with the aim of producing a demonstrator by the end of this year. Work on the first module for the demonstrator, designated UF001, has started at the manufacturer’s facilities in Derby. Its first test run will be carried out ...

  • Delta Air Lines Airbus A220-100

    FAA to stop requiring repeated PW1500G compressor inspections


    Airlines may no longer need to repeatedly inspect low-pressure compressor (LPC) rotors in Pratt & Whitney PW1500G turbofans, which power Airbus A220s.

  • VD An-124-c-Volga-Dnepr

    An-124 operators to conduct disc inspections after November engine failure


    Ukrainian authorities have ordered detailed inspection of the fan discs on Ivchenko-Progress D-18T engines, following the destructive powerplant failure involving an Antonov An-124 last November. The state aviation administration says preliminary investigation results show the fan disc was the “source” of the failure at Novosibirsk, which resulted in multiple ...
