Kamov Ka-92
The Kamov Ka-92 is a high-speed coaxial helicopter design proposed by Kamov of Russia in competition with the Mil Moscow Helicopter Plant for a $1.3 billion project by the Russian government for development of a high-speed helicopter. Design and development The Kamov Ka-92 is part of a program of the newly established Russian Helicopters company, intended to create a new generation of medium-class helicopters capable of cruising at about 500 km/h (312 mph) and flying over a distance of up to 1400 km. Its preliminary design and some specification data were unveiled at the HeliRussia 2009 exhibition near Moscow. The Ka-92 will feature a coaxial rotor system which is distinctive of Kamov products. As on the Mil Mi-X1, a pusher propeller will be used on the Ka-92, but the Kamov will use two instead of one as Mil has chosen. As Kamov Chief Designer Sergey Mikheev explained, the traditional design when the main rotor both lifts and pushes the aircraft forward functions o ...

Klimov
The JSC Klimov (or Joint Stock Company Klimov) presently manufactures internationally certified gas turbine engines, main gearboxes and accessory drive gearboxes for transport aircraft. Originally established as ''Kirill Klimov Experimental Design Bureau'' in Saint-Petersburg under the direction of (Влади́мир Я́ковлевич Кли́мов) (1892–1962), Klimov designed engines for Soviet aircraft based on Renault aircraft engine designs. It may have used the designation Aircraft Repair Factory (aviazavod, ARZ) 117 during the Soviet period. History The Klimov OKB was formed in the early 1930s to produce and improve upon the liquid-cooled Hispano-Suiza 12Y V-12 piston engine for which the USSR had acquired a license. At that time Klimov also manufactured motorcycles. In 1946 the British government allowed Rolls-Royce to sell a number of Nene and Derwent V turbojet engines to the Soviet Union. Klimov OKB was given the task of "metrifying" the British designs, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kamov Aircraft
JSC Kamov (russian: Камов) is a Russian rotorcraft manufacturing company based in Lyubertsy, Russia. The Kamov Design Bureau ( design office prefix Ka) has more recently specialised in compact helicopters with coaxial rotors, suitable for naval service and high-speed operations. History Kamov was founded by Nikolai Ilyich Kamov, who started building his first rotary-winged aircraft in 1929, together with N. K. Skrzhinskii. Up to 1940, the year of Kamov plant establishment, they created many autogyros, including the TsAGI A-7-3, the only armed autogyro to see (limited) combat action. From 2002 AFK Sistema controlled a 51% stake in the company, with MiG controlling the remaining 49%. Kamov was sold to Oboronprom in 2005. Kamov merged with Mil and Rostvertol to form Russian Helicopters. The Kamov brand name was retained, though the new company dropped overlapping product lines.

Sikorsky X2
The Sikorsky X2 is an experimental high-speed compound helicopter with coaxial rotors, developed by Sikorsky Aircraft, that made its first flight in 2008 and was officially retired in 2011. Design and development 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; the Cypher UAV expanded the company's knowledge of the unique aspects of coaxial flight control laws with a fly-by-wire aircraft; and the RAH-66 Comanche developed expertise in composite rotors and advanced transmission design.

Sikorsky S-97
The Sikorsky S-97 Raider is a high-speed scout and attack compound helicopter based on the Advancing Blade Concept (ABC) with a coaxial rotor system under development by Sikorsky Aircraft. Sikorsky planned to offer it for the United States Army's Armed Aerial Scout program, along with other possible uses.Trimble, Stephen"Sikorsky unveils S-97 for high-speed scout and attack helo" ''Flightglobal'', 20 October 2010. The S-97 made its maiden flight on 22 May 2015. Development Background 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. These problems were largely solved on another attempt by the Sikorsky X2 technology demonstrator in 2010. First proposed in response to a Request for Information for the Armed Aerial Scout ...

Piasecki X-49
The Piasecki X-49 "SpeedHawk" is an American four-bladed, twin-engined experimental high-speed compound helicopter developed by Piasecki Aircraft. The X-49A is based on the airframe of a Sikorsky YSH-60F Seahawk, but utilizes Piasecki's proprietary vectored thrust ducted propeller (VTDP) design and includes the addition of lifting wings. The concept of the experimental program was to apply the VTDP technology to a production military helicopter to determine any benefit gained through increases in performance or useful load. "SpeedHawk" is a concept aircraft based on applying X-49A compounding concepts to a production UH-60 Black Hawk offering better performance, range, and increases in useful load. The "SpeedHawk" aircraft includes an SPU (third engine), high forward-swept wing concept, a 45-inch "fuselage plug" cabin extension, and several other drag reducing and performance-oriented improvements, including a rotor hub fairing, landing gear streamlining, and a fly-by-wire fligh ...

Kamov Ka-50
The Kamov Ka-50 "Black Shark" (russian: Чёрная акула, translit=Chyornaya akula, English: kitefin shark, NATO reporting name: Hokum A) is a Soviet/Russian single-seat attack helicopter with the distinctive coaxial rotor system of the Kamov design bureau. It was designed in the 1980s and adopted for service in the Russian army in 1995. It is manufactured by the Progress company in Arsenyev. It is used as a heavily armed scout helicopter. It has a rescue ejection system, rare for helicopters. During the late 1990s, Kamov and Israel Aerospace Industries developed a tandem-seat cockpit version, the Kamov Ka-50-2 "Erdogan" (russian: link=no, Эрдоган, tr, Erdoğan), to compete in Turkey's attack helicopter competition. Kamov also designed another two-seat variant, the Kamov Ka-52 "Alligator" (russian: link=no, Аллигатор, NATO reporting name: Hokum B). Development The Ka-50 is the production version of the V-80Sh-1 prototype. Production of the attack ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Turboshaft
A turboshaft engine is a form of gas turbine that is optimized to produce shaftpower rather than jet thrust. In concept, turboshaft engines are very similar to turbojets, with additional turbine expansion to extract heat energy from the exhaust and convert it into output shaft power. They are even more similar to turboprops, with only minor differences, and a single engine is often sold in both forms. Turboshaft engines are commonly used in applications that require a sustained high power output, high reliability, small size, and light weight. These include helicopters, auxiliary power units, boats and ships, tanks, hovercraft, and stationary equipment. Overview A turboshaft engine may be made up of two major parts assemblies: the 'gas generator' and the 'power section'. The gas generator consists of the compressor, combustion chambers with ignitors and fuel nozzles, and one or more stages of turbine. The power section consists of additional stages of turbines, a gear reduction ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Klimov TV7-117
The Klimov TV7-117 is a Russian turboprop engine certified in 1997 to power the Ilyushin Il-114 regional commuter aircraft. The new engine features enhanced reliability, fuel economy and greater service life compared to its predecessors produced in the former Soviet Union. The engine has a modular design. The nine modules can be replaced in the field, which dramatically reduces costs and accelerates repair and maintenance. The engine has an electronic-hydromechanical control system. The TV7-117S engine has been offered to power the newest Russian turboprop aircraft such as Ilyushin Il-112 and Ilyushin Il-114. In addition, Klimov developed the TV7-117V turboshaft to power rotary-wing aircraft, such as the Mil Mi-38, and marine drives for high-speed boats and industrial electric power plants. The TV7-117 engine family is produced by Klimov JSC (St. Petersburg), Chernishov JSC (Moscow) and the Baranov JSC (Omsk) and Aerosila propellers for TV7-117S variants. Variants * TV7-117S 28 ...
