The Embraer EMB 121 Xingu (pronounced “ Schinguh ”) is a twin-engine turboprop aircraft produced by the Brazilian aircraft manufacturer Embraer , which was designed as a light business jet in the mid-1970s. The name " Xingu " is derived from a tribe of the same name and a river in the Amazon region . The prototype (registration number PP-ZXI) took off for its maiden flight on October 10, 1976. The first production aircraft (registration number PP-ZCT) flew on May 20, 1977.
history
The design of this aircraft comes from the larger EMB 110 Bandeirante, from which the wings and engines were taken. The hull, however, was redesigned for the Xingu. The EMB 121 was the first aircraft manufactured in Brazil with a pressurized cabin and the first to cross the Atlantic , accompanied by an EMB 110 . The first flight of this aircraft was on October 2, 1976, and on December 4, 1976 the aircraft was presented to the public. The first series machine (registration number PP-ZCT) flew on May 20, 1977. In 1979 it was approved by the various aviation authorities. The Xingu I can accommodate five to six passengers.
Five years later, on September 4, 1981, the further developed EMB 121A1 Xingu II appeared, which in addition to more powerful engines offers larger tanks and space for eight to nine passengers. The aircraft was not granted outstanding economic success, after 106 (according to other sources 107) copies produced, production was discontinued in August 1987. 51 aircraft were sold abroad, mainly to France . The French armed forces are the world's largest operator with 43 aircraft currently in operation. In addition to being used as a transport aircraft, the Xingu is used to train prospective French transport aircraft and, according to current plans, should fulfill this task by 2025. The first operator of the aircraft, however, was the Brazilian army, which stationed its aircraft in the capital Brasilia.
On the 40th birthday of the manufacturer Embraer and the 30th anniversary of the certification of the type in 2009, the prototype of the Xingu with the registration number PP-ZXI was extensively restored by students at a technical university.
construction
The EMB 121 Xingu is a cantilever low- wing aircraft with a retractable nose wheel and a pressurized cabin . It is normally flown by two pilots and can accommodate up to nine passengers, depending on the interior. Two propeller turbines of the type Pratt & Whitney Canada PT6A-28 with an output of 680 WPS each, which drive three-blade propellers from Hartzell, serve as the drive. 49 machines of this basic version were built. The machines delivered from 1982 were given the designation EMB 121A1 Xingu II. They owned Pratt & Whitney Canada PT6A-135 with an output of 750 WPS, which drove a four-blade propeller, had a larger fuel capacity and a small strake left and right at the lower stern area. This type could also be flown by a pilot. Embraer converted 47 machines of the first series to the Xingu II standard.
