The Invictus features a rather conventional configuration with a single fully articulated main rotor and a ducted tail rotor. Much like Boeing, Bell decided to use proven technologies to reduce ...

Some observers at Tuesday's event remarked how the streamlined, lightweight fuselage design of the 360 Invictus resembled the body of a shark, particularly the vertical canted ducted tail rotor ...

Currently being developed by the Bell helicopter company, it does away with the tail rotor, substituting four ducted variable-RPM fans. While these are electrically powered by a main-rotor-located ...

single rotor heli’s. Defense and military folks, on the other hand, opt for a fixed wing UAV design that needs a launch mechanism to get airborne. A different approach to flight is the ducted ...

removing the tail rotor, and adding twin ducted fans for higher performance, and longer range. This patented coaxial rotor, twin-ducted fan design concept forms the basis of the current JMR proposal.

the only ducted propeller scheme in recent memory was the ducted tail rotor of the Invictus attack helicopter—also a Bell design—and even that was recently deleted from the final aircraft ...

Future Bell helicopter designs could come with split-tip main rotor blades and ... disadvantages of traditional tail rotors and the added weight and complexity of ducted fan designs such as ...

A while back, we wrote about the ducted fan, single rotor, VTOL drone that [Armin Strobel] was working on. It wasn’t quite finished then, and hadn’t got off the ground yet. He’s posted an ...

Airbus Helicopters has traditionally opted for standard tail rotor designs on the majority of its rotorcraft, with the only excpetion its Fenestron ducted fan design that is used on certain models ...

But there’s a key supporting actor on nearly all helicopters: the smaller tail rotor. It plays a crucial role as an anti-torque device—it prevents the helicopter from spinning around in ...
