“Today we unveil our bold vision for the future of high-speed rotorcraft. This new project, pulling together the skills and know-how of dozens of European partners through the Clean Sky 2 initiative, aims to bring increased speed and range at the right cost, thanks to a simple, safe and proven aerodynamic formula.

Rotorcraft Engineering. The University is engaged in a wide range of research and educational activities related to vertical flight technology. Inled by faculty in the aerospace engineering department, a Penn State team was competitively awarded one of the three Rotorcraft Centers of Excellence (RCOE) by the newly formed National Rotorcraft Technology Center (NRTC).

its competitiveness as a high speed rotorcraft concept. BACKGROUND The U.S. Navy, in conjunction with Bell and Boeing Helicopter, are developing the V “Osprey” to perform an “over-the-beach” assault mission primarily for the Marine Corps. Presently, the Marine Corps is planning on utilizing.

Re: A Breakthrough Rotorcraft Technology 11/15/ PM In case someone is waiting for more activity on this topic, please note that I started another conversation called "A New & Efficient High-Speed Rotorcraft" and there has been a fair amount of activity there.

Requests from the rotorcraft industry underline the necessity for future rotorcraft using variable rotational speeds. However, the A or the EC and Mi-8 already show the potential of this. Airbus rival Sikorsky flew the X2 compound rotorcraft in the mid s. You'll see some of the technology from that aircraft in the Lockheed S military helicopter.

General NASA must continue to provide the necessary resources for aerodynamics research and validation, including resources focused on specific key technologies, resources to maintain and enhance ground and flight test facilities, and resources for enhanced analytical and design capabilities.

Specific. The following research topics should serve as the focus of NASA's research effort in. they have likely developed in the course of designing their commercial hybrid vehicle, the book by Carichner and Nicolai does provide some insight into their modeling and simulation resources (Grant E.

Carichner, ). The book “Airship Technology” provides some useful references to airship development tools (Khoury, ). Re: A New & Efficient High-Speed Rotorcraft 11/05/ AM If you don't need the surfaces for control in normal modes, or as a fuel saving effort, then all you need is emergency mode systems.

pop out a giant hang glider of light materials or parachutes, or whatever. Billed as the future of high-speed rotorcraft, Airbus Helicopters has developed a compound helicopter concept that is optimized for a cruising speed of approximately mph. The concept, named Racer, uses a main rotor for lift and basic flight mode, two lateral pusher rotors that generate thrust for forward flight and a box-wing to provide lift.

What is "slowed rotor/compound technology," you may ask. Basically, it's an aircraft where you put a rotor on the top (like a helicopter) for slow speed flight, and put wings on it for high speed flight.

To help reduce drag in high speed flight, you slow the rotor down to an rpm much lower than where it operates at slow speed flight. This ringbound book and CD-ROM disc set provides a comprehensive guide to maglev train technology and America's new program of high-speed passenger rail travel, the High-Speed Intercity Passenger Rail Program (HSIPR), announced by President Obama in January /5(2).

Future Vertical Lift (FVL) is a plan to develop a family of military helicopters for the United States Armed different sizes of aircraft are to be developed, sharing common hardware such as sensors, avionics, engines, and countermeasures.

The U.S. Army has been considering the program since FVL is meant to develop replacements for the Army's UH Black Hawk, AH Apache, CH Issued by: United States Department of Defense. Although the Russian Ministry for Industry and Trade has stopped funding research into high-speed rotorcraft for commercial applications, the country's Ministry of Defence has not lost interest.

The horizontal cruciform rotor wing, also known as the X-wing, is a form of the Stopped rotor. Teledyne Ryan studied the concept in the s and took out a number of patents. The X-Wing circulation control rotor was developed in the mids under DARPA funding. The concept was first developed by the David W.

Taylor Naval Ship Research and Development Center and an experimental rotor built. Among many technological issues for the high speed rotorcraft, designing 1)a rotor for high speed (high advanced ratio), 2)a low drag airframe and 3)a sophisticated rotorcraft configuration without adverse aerodynamic interferences caused by neighboring rotors and wings is the most challenging area.

The U.S. Army has revealed new details about what it wants from its high-speed, long-range replacement for the UH Black Hawk series of helicopters.
