The companies are offering the SB-1 Defiant, which is based on Sikorsky's X2 technology that replaces the single main rotor on a traditional helicopter with a coaxial rotor
, and a pusher-propeller that replaces a traditional tail rotor, said Chris Van Buiten, vice president of Sikorsky Innovations.
aircraft are gaining interest in civil and military applications, as well as in the small, Unmanned Aerial Vehicle (UAV) market.
Black Shark is a single-seat Russian attack helicopter with the unique coaxial rotor
system of the Kamov design bureau.
subsidiary (NYSE: UTX), said it has made the successful first flight of the S-97 RAIDER helicopter, a rigid coaxial rotor
prototype designed to demonstrate a combination of maneuverability, hover ability, range, speed, endurance and survivability.
Going faster is not the only purpose of the story," Steve Engebretson, Director advanced military programmes at Sikorsky told Armada International, "we want to improve helicopter's manoeuvrability and properties, and our coaxial rotor
configuration and pusher propeller is perfect for this purpose.
Here we open a new horizon to work on coaxial rotor
helicopters with a new approach.
There are many different types of small unmanned copters, such as traditional helicopter, the twin-rotor or tandem-rotor helicopter, the coaxial rotor
helicopter and four-rotor helicopter.
The X2 Technology demonstrator combines an integrated suite of technologies intended to advance the state-of-the-art, counter-rotating coaxial rotor
A single CTS800 turboshaft engine powers a counter-rotating coaxial rotor
and pusher propeller.
Gyrodyne subsequently licensed its coaxial rotor
technology to Germany's Dornier and Israel's IAI Malat.
Sikorsky's X2 counter-rotating coaxial rotor
technology unofficially tested at 258 miles per hour last week, bypassing a previous record set by a Westland Lynx in 1986.
Both the G70 and E70 employ a 70-inch coaxial rotor
and control system, minimizing the complexity of coaxial systems of the past, but scalable to future craft, smaller or larger in size.
