Bell announced its new project after the Bell 429 and Bell V-22, the super medium Bell 525, previously it was known as Project X or Magellan. The Helicopter is overall designed for trips of 50 to 500 nautical miles, and has a 5-blade main rotor powered by twin engines, digital controls and Garmin G5000H screen, with planned seating for 16-20 people.

A full-scale mockup of the helicopter was first built to optimize the layout of technological, operational, and ergonomic features. A wind tunnel model TsAGI was created to test flight characteristics and improve aerodynamic airframe layout. Laboratories tested the air intakes' dust device to improve efficiency.
Sikorsky developed the X2 helicopter on a $50 million budget. The design includes expertise gathered from several earlier design projects. The S-69/XH-59A Advancing Blade Concept Demonstrator had shown that high speed was possible with a coaxial helicopter with auxiliary propulsion supplied using two jet engines, but that vibration and fuel consumption was excessive; [2] [3] [4] the Cypher UAV ...
Sikorsky's earliest attempt at a fast compound helicopter with stiff coaxial rotors was the Sikorsky S-69 (XH-59A) flown in the 1970s. Its top speed was over 260 knots but its excessive fuel consumption, vibration and complexity requiring the full-time attention of two pilots led to the program's cancellation. [5]
The Sikorsky S-92 is an American twin-engine medium-lift helicopter built by Sikorsky Aircraft for the civil and military helicopter markets. The S-92 was developed from the Sikorsky S-70 helicopter and has similar parts such as flight control and rotor systems.
The design has seating for two crew members and ten passengers. It is expected to have a lower price than comparable western helicopters. [2] [3] The aircraft has a gross weight of 3,850 kg (8,488 lb), a maximum cruising speed of 260 km/h (140 kn), a service ceiling of 6,000 m (19,685 ft) and a range of 693 km (374 nmi). Maximum take-off ...
The 47 became the first helicopter certified for civilian use on 8 March 1946. [ 1 ] [ 2 ] The first civilian delivery was made on 31 December 1946 to Helicopter Air Transport . [ 3 ] More than 5,600 Bell 47s were produced, including those under license by Agusta in Italy, Kawasaki Heavy Industries in Japan, and Westland Aircraft in the United ...
The CH-1A was the first helicopter to land on Pikes Peak, at an altitude of 14,110 feet (4,300 m) on 15 September 1955, [2] it had a higher cruise speed than comparable machines, and a CH-1B, modified with an FSO-526-2X engine, set an official FAI world altitude record for helicopters of 29,777 feet [note 1] on December 28, 1957, while being ...
