    Helicopter News & Discussion

    I thought we could do with a dedicated thread for helicopter news and discussion, and the recent first flight of Sikorsky's S-97 Raider demonstrator seems as good a starting point as any. Copypasta from the main news thread:

    An exciting achievement. But where did the shrouding around and between the rotor hubs go?

    The design is a record breaker working prototype. Not the proposed one.

    Rolls-Royce to develop turbine options for Bells V-280 and V-247

    Bell and Rolls-Royce are developing an end-to-end engine integrated solution for V-280 as an option for future procurements, says Bell. However, we fully recognize that the government has not defined its engine sourcing strategy.

    The advantage of the X-3 layout is that it can scale up nicely.

    The S-97 might run into problems of providing sufficient thrust through one propellor, and length of driveshaft.

    Airbus Helicopters launches 5-bladed H145 upgrade

    The blades incorporate the latest airfoil design to produce more thrust than previous blades at the same power. While five blades have more drag than four blades in a rotor, Humpert said improvements to the aerodynamics of the rotor cuff of the blade had actually allowed the new H145s blades to provide more lift. This is the aerodynamic evolution which is technically behind it, he said. The new H145s blades fix directly onto the main rotor mast, meaning fewer parts and simplified maintenance. Airbus Helicopters Photo
    The new main rotor system has been simplified with no main rotor head so the blades are attached directly to the rotor mast. This means fewer parts, resulting in the lower weight and simplified maintenance.

    The blades have been designed for simplicity and thrust efficiency, said Humpert, and provide some different characteristics during flight. He said these included an increase in comfort level (with reduced vibration), while maintaining the same levels of noise and efficiency as the existing H145.

    Brazils navy ordered three Airbus H135 light twin-engine helicopters.

    The helicopters will be operated by the 1st General Purpose Helicopter Squadron and will be used for missions such as special operations, transport of troops and freight, naval inspection, search and rescue and medical evacuation, says Airbus Helicopters. The aircraft are replacements for the Brazilian navys twin-engine, light utility Eurocopter AS355 cureuil helicopter.

    From the Osprey to the CH-53K: Progress in Building a Maintainable Aircraft

    Arent you with the logs demo shaping domain knowledge rather than manuals to launch the K fleet experience?

    Lambert: That is correct.

    We are focused on having the Marines working with the airplane get familiar and comfortable with the maintenance approach and indeed, to shape that approach.

    In Osprey interviews which you published from a decade ago, one of the challenges highlighted was the lack of knowledge, the lack of being comfortable with the airplane which led to a high amount of premature removal of parts for unknown failures.

    We are focused on training the Marines to make good sound judgment calls when troubleshooting and performing maintenance.
    An interesting piece worth reading

    Airbus to Pursue US Army Helo Program With X3-Based Platform

    Airbus Helicopters CEO Bruno Even said the company has proposed an aircraft design based on its X3 technology, which recorded a speed of more than 290 miles per hour before it was retired in 2014.

    Even said Airbus is enhancing the technology to meet future military requirements for high-speed helicopters.
