Announced in 2007, the R66 was designed to be the company's first turbine-powered product and to extend its product range to compete with larger helicopters manufactured by Bell Helicopter and Eurocopter. Most of the R66 design is based on the earlier piston-engine R44. Robinson started taking orders for the R66 in February, 2010.
An aircraft engine, often referred to as an aero engine, is the power component of an aircraft propulsion system. Aircraft using power components are referred to as powered flight. [1] Most aircraft engines are either piston engines or gas turbines, although a few have been rocket powered and in recent years many small UAVs have used electric ...
Since delivering their first helicopter shortly after Federal Aviation Administration type certification of the F-28 model in April 1965, Enstrom helicopter has produced, as of 2007, approximately 1,200 aircraft. [2] The company produces three models, the F-28, the more aerodynamic 280 and the turbine-powered 480, each with their own variants.
The company has built more than 325,000 piston aircraft engines and powers more than half the world's general aviation fleet, both rotary and fixed wing. [1] Lycoming has been a principal pioneer of turbine engines for medium and large helicopters, and has also produced engines for small jetliners and business jets. [2] [3] [4]
The technology of Allison's earlier T38 design evolved into the Allison T56, used to power the Lockheed Electra airliner, its military maritime patrol derivative the P-3 Orion, and the C-130 Hercules military transport aircraft. The first turbine-powered, shaft-driven helicopter was the Kaman K-225, a development of Charles Kaman's K-125 ...
It was the last piston-engined helicopter to be operated by the United States Marine Corps (USMC), having been replaced by turbine-powered types such as the UH-1 Huey and CH-46 Sea Knight; in the USMC, the H-34 was often called the "HUS" after its original designation in that service. A total of 2,340 H-34s were manufactured between 1953 and ...
On 11 December 1951, the Kaman K-225 became the first turbine-powered helicopter in the world. Two years later, on 26 March 1954, a modified Navy HTK-1, another Kaman helicopter, became the first twin-turbine helicopter to fly. [97] However, it was the Sud Aviation Alouette II that would become the first helicopter to be produced with a turbine ...
The CH-37 was one of the last heavy helicopters to use piston engines, which were larger, heavier and less powerful than the turboshaft engines employed in later military helicopters. This accounted for the CH-37's fairly short service life, all being withdrawn from service by the late 1960s, replaced in Army service by the distantly related CH ...
