The North American Sabreliner (later sold as the Rockwell Sabreliner) is a mid-sized business jet developed by North American Aviation. It was offered to the U.S. Air Force in response to their Utility Trainer Experimental (UTX) program. It was named "Sabreliner" due to the similarity of the wing and tail to North American's F-86 Sabre jet fighter."〔 Military variants, designated T-39 Sabreliner, were used by the U.S Air Force, U.S. Navy and U.S. Marine Corps after the Air Force placed an initial order in 1959.〔"(Fact Sheets: North American T-39A Sabre Liner )." National Museum of the United States Air Force.〕 The Sabreliner was also developed into a commercial variant. ==Design and development== North American began development of the Sabreliner as an in-house project, and in response to the UTX request for proposals, they offered a military version to the Air Force. UTX combined two different roles, personnel transport and combat readiness training, into the same aircraft.〔 The civilian version prototype, which carried the model number NA-265, made its first flight on September 16, 1958. It was powered by a pair of General Electric YJ85 turbojet engines. The type received its FAA type certification in April 1963. The UTX candidate, designated the T-39A, was identical in configuration to the NA-265, but when the contract was awarded and the T-39A entered production, it was powered with two Pratt & Whitney JT12A-8 turbojet engines.〔 The civilian production version, or Series 40, was slightly refined over the prototype, with more speed and a roomier cabin. North American then stretched the design by 3 feet 2 inches, providing greater cabin space, and marketed it as the Series 60, which was certificated in April 1967. The cabin was made taller for the Series 70 and General Electric CF700 turbofans were installed for the Series 75A (also branded as the Series 80).〔"Sabreliner Structural Repair Manual - All Models NA-265 Aircraft", Report No. NA-66-1032 Revision 10, March 16, 1990.〕 By 1973, North American had merged with Rockwell Standard under the name Rockwell International. In 1976 Rockwell contracted Raisbeck Engineering to redesign the wing of the Sabreliner series.〔(Company Bio ) Retrieved August 18, 2014.〕 The resulting Raisbeck Mark V wing was the first supercritical wing in service in the United States.〔Timmons, Lawrence M. "Improving Business Jet Performance - The Mark V Sabreliner", SAE 790582, presented at the Business Aircraft Meeting and Exposition Century II, Wichita Kansas, April 1976〕 The Mark V wing was combined with Garrett AiResearch TFE731 turbofan engines, to create the Series 65.〔Mathwing, George E., "The Rockwell International Sabreliner 65 Case Study in Aircraft Design"〕 Sabreliner models 60 and 80 were retrofitted with the Mark V wing as the Series 60A (STC SA687NW) and Series 80A (STC SA847NW). Sabreliner production came to a close in 1981. The next year, Rockwell sold its Sabreliner division to a private equity firm which formed Sabreliner Corporation, the support organization for continuing operators.〔 Over 800 Sabreliners were produced, of which 200 were T-39s.〔 A number of retired military T-39s have also entered the civilian world, since the military versions also carry FAA type certification. , 56 examples have been lost in accidents.〔"(Rockwell Sabreliner ). 56 hull-loss occurrences, last updated 5 May 2007." Aviation Safety Network.〕 The Series 65 was the last series run and 76 of them were produced, mostly for the private market. Monsanto has the oldest continuously operating company corporate jet division starting with its purchase of a Saberliner 40. The original Navy version, the T3J-1, redesignated T-39D after the 1962 redesignation of USN/USMC/USCG aircraft, was initially fitted with the radar system from the F3H-1 Demon all-weather fighter and used as a radar trainer for pilots of that aircraft. The T-39D aircraft was subsequently introduced into the Basic Naval Aviation Observer (NAO), later Student Naval Flight Officer (SNFO) program. Three versions of the T-39D were used throughout the 1960s, 70s and 80s: one without radar for high altitude instrument navigation training and low altitude visual navigation training in the SNFO Intermediate syllabus, a second variant equipped with the APQ-126 radar from the Vought A-7 Corsair II for training primarily bombardier/navigators, reconnaissance attack navigators and electronic countermeasures officers in attack aircraft, and a third variant with the APQ-94 radar from the F-8 Crusader for training radar intercept officers in fighter aircraft. The T-39N and T-39G are currently used in the NFO Strike and Strike Fighter syllabi in training USN and USMC Student Naval Flight Officers, various NATO/Allied/Coalition student navigators. Foreign students also train in the T-39 in place of the Beechcraft T-1 Jayhawk during the Intermediate Jet syllabus. The Sabreliner requires a minimum crew of two, and depending on cabin configuration, can carry up to seven passengers (NA-265 through NA-265-40) or ten passengers (NA-265-60 and subsequent models). As a Navy flight training aircraft, it will typically fly with a pilot, one or two NFO Instructors and two to three Student NFOs or student navigators/CSOs.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「North American Sabreliner」の詳細全文を読む スポンサード リンク
