Ducted fan tail rotors have also been used in the Russian Kamov Ka-60 medium-lift helicopter, [17] and also on the Japanese military's Kawasaki OH-1 Ninja reconnaissance rotorcraft. French light helicopter manufacturer Hélicoptères Guimbal has also used a Fenestron for their Guimbal Cabri G2, a compact reciprocating engine-powered rotorcraft ...
The EC130 is a single-engine helicopter. It uses a three-bladed Starflex main rotor which is matched to an enclosed tail fan anti-torque device, known as a Fenestron, the latter feature replacing the traditional tail rotor found on the older AS350. The Fenestron has unevenly spaced blades to reduce noise generation by 50% compared to a ...
The R44 is a single-engined helicopter with a semi-rigid two-bladed main rotor, a two-bladed tail rotor and a skid landing gear. It has an enclosed cabin with two rows of side-by-side seating for a pilot and three passengers. Tail rotor direction of rotation on the R44 is reversed compared to the R22 for improved yaw control authority.
In the early 1980s, the Israeli Navy sought to acquire a purpose-built maritime helicopter to bolster its over-the-horizon detection and targeting capabilities. Several helicopter types were evaluated, including the Westland Lynx and SH-60 Seahawk; in 1983, Israel announced the selection of the HH-65 Dolphin. Seeking a few examples to gain ...
The tail rotor is a smaller rotor mounted so that it rotates vertically or near-vertically at the end of the tail of a traditional single-rotor helicopter. The tail rotor's position and distance from the center of gravity allow it to develop thrust in a direction opposite that of the main rotor's rotation, thereby countering the torque effect ...
The A.104 was a slightly enlarged version of the A.103, and added a second seat beside the pilot's seat. The cockpit was enclosed by a perspex bubble with the engine at the rear and the tail rotor carried on an enclosed boom. Two piston-engined prototypes were built, followed by a single example of a turbine-engined variant designated A.104BT ...
The principal amongst these changes was the repositioning of the tail rotor from the helicopter's left side to the right, which facilitated an increase in the effectiveness of the tail rotor. [11] The AH-1 was the first U.S. Army helicopter not named for a Native American people since the practice began with the H-13 Sioux and continued with ...
