TH-67
The Bell 206 is a family of two-bladed, single- and twin-engined helicopters, manufactured by Bell Helicopter at its Mirabel, Quebec, plant. Originally developed as the Bell YOH-4 for the United States Army's Light Observation Helicopter program, it was not selected by the Army. Bell redesigned the airframe and successfully marketed the aircraft commercially as the five-place Bell 206A JetRanger. The new design was eventually selected by the Army as the OH-58 Kiowa. Bell also developed a seven-place LongRanger, which was later offered with a twin-engined option as the TwinRanger, while Tridair Helicopters offers a similar conversion of the LongRanger called the Gemini ST. The ICAO-assigned model designation "B06" is used on flight plans for the JetRanger and LongRanger, and the designation "B06T" is used for the twin-engined TwinRangers. Development Origins and JetRanger On October 14, 1960, the United States Navy solicited responses from 25 aircraft manufacturers to a reque ...

Bell OH-58 Kiowa
The Bell OH-58 Kiowa is a family of single-engine single-rotor military helicopters used for observation, utility, and direct fire support. It was produced by the American manufacturer Bell Helicopter and is closely related to the Model 206A JetRanger civilian helicopter. The OH-58 was originally developed during the early 1960s as the ''D-250'' for the Light Observation Helicopter (LOH). While the rival Hughes OH-6 Cayuse was picked over Bell's submission in May 1965, the company refined its design to create the Model 206A, a variant of which it successfully submitted to the reopened LOH competition two years later. The initial model, designated by the service as the ''OH-58A'', was introduced in May 1969. Successive models would follow, often with uprated engines, enhanced protection systems, and other improvements, cumulating in the ''OH-58F''. Additional improvements, such as the ''OH-58X'', were proposed but ultimately not pursued. During the 1970s, the US Army became ...

Hiller Aircraft
Hiller Aircraft Company was founded in 1942 as Hiller Industries by Stanley Hiller to develop helicopters. History Stanley Hiller, then seventeen, established the first helicopter factory on the West Coast of the United States, located in Berkeley, California, in 1942, under the name "Hiller Industries," to develop his design for the coaxial-rotor XH-44 "Hiller-Copter" for the U.S. Army. The XH-44 became operational in 1944.Hiller Helicoptertimeline(accessed Nov 9 2011) In collaboration with Henry J. Kaiser, it became United Helicopters in 1945. In the postwar years, United Helicopter produced a number of innovative helicopter designs for military and civilian purposes, including coaxial-rotor and tailless designs, as well as more conventional models. In January, 1949, a Hiller 360 became the first civilian helicopter to cross the United States. Besides helicopters, in the year after World War II, Stanley Hiller researched a two-man rocket-jet aircraft design that took off ...

Bell 206L-4 LongRanger IV C-FTHU (CTV News)
A bell is a struck idiophone, directly struck idiophone percussion instrument. Most bells have the shape of a hollow cup that when struck vibrates in a single strong strike tone, with its sides forming an efficient resonator. The strike may be made by an internal "clapper" or "uvula", an external hammer, or—in small bells—by a small loose sphere enclosed within the body of the bell (jingle bell). Bells are usually cast from bell metal (a type of bronze) for its resonant properties, but can also be made from other hard materials. This depends on the function. Some small bells such as ornamental bells or cowbells can be made from cast or pressed metal, glass or ceramic, but large bells such as a church, clock and tower bells are normally cast from bell metal. Bells intended to be heard over a wide area can range from a single bell hung in a turret or bell-gable, to a musical ensemble such as an English ring of bells, a carillon or a Russian Russian Orthodox bell ringing, zvon ...

Bell 427
The Bell 427 is a twin-engine, multirole, light utility helicopter designed and manufactured by Bell Helicopter and Samsung Aerospace Industries. It has been replaced in production by the larger Bell 429. Development Bell has tried several incarnations of a twin version of its successful Bell 206 series, including the stillborn Bell 400 and 440 in the mid-1980s, and the limited-production Bell 206LT TwinRanger in the early 1990s.Frawley, Gerard. ''The International Directory of Civil Aircraft, 2003–2004'', p. 43. Aerospace Publications Pty Ltd, 2003. . Bell's original concept for a replacement for the 206LT TwinRanger was the ''Bell 407T'', a relatively straightforward twin-engine development of the Bell 407 with two Allison 250-C22B engines. However, Bell concluded that the payload-range performance of the 407T would not be sufficient.Frawley, Gerard. ''The International Directory of Civil Aircraft, 2003–2004'', p. 47.

Bell 400
The Bell 400 TwinRanger was a prototype four-bladed, twin-engine civil helicopter developed by Bell Helicopter in the 1980s. Both the TwinRanger and another planned version, the Bell 440, were attempts to market a twin-engine development of the Model 206L LongRanger. The Bell 400A was a planned single-engine version of the 400. TwinRanger, however development was canceled when Bell could not acquire enough orders for production. The TwinRanger name was later used for a twin-engine version of the LongRanger produced from 1994 to 1997. Development Bell has tried several incarnations of a twin-engine version of its successful Bell 206 series. The ''TwinRanger'' name dates back to the mid-1980s when Bell first considered developing a twin-engine version of the LongRanger. The ''Bell 400 TwinRanger'' featured a reprofiled fuselage, two Allison 250 turboshafts, the OH-58D Kiowa's four-bladed main rotor, and a new shrouded tail rotor.Frawley, Gerard: ''The International Directiory ...

Rolls-Royce Model 250
The Allison Model 250, now known as the Rolls-Royce M250, (US military designations T63 and T703) is a highly successful turboshaft engine family, originally developed by the Allison Engine Company in the early 1960s. The Model 250 has been produced by Rolls-Royce since it acquired Allison in 1995. Development In 1958, the Detroit Diesel Allison division of General Motors was chosen by the US Army to develop a new light turbine engine to power a "Light Observation Aircraft" (LOA), to replace the Cessna O-1A Bird Dog. At this stage the US Army was unsure whether to have a fixed- or rotary-wing aircraft, so Allison was instructed to consider both applications. Design studies undertaken considered a wide range of possible mechanical configurations for the turboprop/turboshaft. These studies culminated in the testing of the first prototype engine, designated YT63-A-3, in April 1959. In 1960, the US Army settled for a rotary wing platform. The YT63-A-3 first flew in a variant of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Robinson R66
The Robinson R66 is a helicopter designed and built by Robinson Helicopter Company. It has five seats, a separate cargo compartment and is powered by a Rolls-Royce RR300 turboshaft engine. The R66 is slightly faster and smoother than the Robinson R44 from which it is derived. The R66 received both type and production certificates from the U.S. Federal Aviation Administration (FAA) on October 25, 2010. Development 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. It went into preliminary production in 2010, and full production in 2011. The existing two-seat R22 and four-seat R44 continued in production. A four-seat police version of the R66 has entered production with a forward looking infrared (FLI ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
