October 28, 2008 Helicopters featuring coaxial rotor designs are not exactly new. The co-axial design of a pair of rotors mounted on the same mast and with the same axis of rotation, but turning ...

Typically, a rotor head has exposed structures which generate drag during flight and therefore slow down the helicopter. LATTE sought to solve this by encapsulating the rotor head within an ...

This necessitates multiple complex control linkages to properly actuate each rotor, because they're both using a common base to spin in opposite directions.And the final dual-rotor design is the ...

Marenco Swisshelicopter is testing a redesigned main rotor head for its SKYe SH09 light single and is now planning on obtaining EASA certification between June and October 2016, adding a few ...

It’s one of the most recognizable—and puzzling—features in military aviation: a large dome perched atop a helicopter. But this “strange ball” is more than just design flair—it’s high ...

Once the hydrogen peroxide motors spin the rotor up to approximately 750 RPM, the pilot simply pulls on a collective lever, similar to a normal helicopter, to climb to the desired altitude.

FORT RUCKER, Ala. -- Before turbine engines took over the world of rotor-wing Aviation, a proof-of-concept system revolutionized helicopter flight with a radical new rotor design. The Lockheed CL ...

An extensive modification program to prototype P3 has introduced a new main rotor head design, a new main gearbox with extended mast and a Garmin G3000H avionics suite. The ...

Attempts to combine the vertical take-off and landing (VTOL) capabilities of a helicopter with the high-speed flight and long range capabilities of a fixed-wing aircraft have been tackled in a ...

He said that the main rope did not break but was prevented from wrapping around the main rotor by a smaller, secondary rope that freed it. "Within about two or three seconds, the helicopter would ...
