Bell 206
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 ...

Dallas, Texas
Dallas () is the third largest city in Texas and the largest city in the Dallas–Fort Worth metroplex, the fourth-largest metropolitan area in the United States at 7.5 million people. It is the largest city in and seat of Dallas County with portions extending into Collin, Denton, Kaufman and Rockwall counties.

Bell 206L-4 LongRanger IV C-FTHU (CTV News)
A bell is a 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 zvon which are tuned to a common scale and ins ...

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 o ...

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 (FL ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bell 505 Jet Ranger X
The Bell 505 Jet Ranger X (JRX) is an American/Canadian light helicopter developed and manufactured by Bell Helicopter. The Bell 505 was unveiled at the 2013 Paris Airshow in June 2013 as the Bell SLS (Short Light Single). The Bell 505 designation was officially announced in February 2014. Its first flight occurred on November 11, 2014. The helicopter was certified by Transport Canada in December 2016. Design and development The helicopter was unveiled at the 2013 Paris Airshow on June 17, 2013 as the Bell SLS (Short Light Single). The model designation was later announced at HAI Heli-Expo 2014 in Anaheim, California on February 25, 2014. The Bell 505 is a "clean sheet" design, but uses some dynamic components, such as the rotor system, of the Bell 206L-4. The airframe is constructed of metal and composites, and has a 22-square-foot (2.04 m²) flat floor and an 18-cubic-foot (0.51 m³) luggage bay. The Safran Arrius 2R is used with a dual-channel FADEC and a 3,000-hour ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bell 47J Ranger
The Bell 47J Ranger is an American single-engine single-rotor light helicopter manufactured by Bell Helicopter. It was an executive variant of the highly successful Bell 47 and was the first helicopter to carry a United States president. Design and development The 47J was a four-seat variant of the earlier three-seat Bell 47H. The 47H was a deluxe variant of the 47G with a fully clad fuselage and an enclosed cabin. The 47H proved to be too small, so Bell developed the 47J. The 47J was a single pilot aircraft with the pilot seat and controls centered in the front of the cabin, and positioned close to the 180° view unobstructed Lexan "bubble" windscreen. A single bench seat at the rear of the cabin spanned its entire width and allowed for a passenger capacity limited by weight to typically 3 or 4 adults. Operational history In March 1957 two Bell 47Js were bought by the United States Air Force as presidential transport and designated H-13J. On 13 July 1957 a H-13J was the first ...
