The Aérospatiale SA 321 Super Frelon ("Super Hornet") is a medium-weight transport helicopter made by the French manufacturer Aérospatiale . The tasks of the helicopter include the areas of transport, rescue (SAR) and anti-submarine combat.
history
In the mid-1950s, the French army was looking for a new large helicopter, whereupon SNCASE proposed the X 316 project and at the beginning of 1956 received the order to build two prototypes called Sud-Aviation SA 3200 Frelon. This 7-tonne class helicopter made its maiden flight on June 10, 1959 with Jean Boulet , Roland Coffignot, Joseph Turchini and Jean-Marie Besse on board in Le Bourget . The helicopter, equipped with a four-blade rotor and short tail boom, did not meet expectations, however, and so in April 1960 a revised and much larger design was developed by the company, which has since been renamed Sud Aviation. The official development of the helicopter, now called SA 3210, began in April 1961 under the direction of chief engineer René Mouille, with Sikorsky being entrusted with the development of the six-blade rotor and Fiat with the gearbox. The first prototype made its maiden flight on December 7, 1962 in Marignane with the same crew on board. The first flight of the second prototype, a naval version with support floats, followed on May 21, 1963. After several world record attempts with the prototypes and four pre-series machines, series production of the SA 321 began in September 1964. The first machine was delivered to the navy - army and air force meanwhile lost interest - took place in August 1966, but due to a crash, production was only started at full capacity from the end of 1967.
The SA 321 is also often referred to as the "Hummel" because the helicopter is heavy, not very agile and slow. In addition to being delivered to France, the helicopter was also bought by Israel and South Africa in the 1960s . Later Libya (last delivery 1981) and Iraq also put the machine into service. Between 1975 and 1977, 13 SA 321Ja were delivered to the People's Republic of China , where the Changhe Aircraft Factory (later Changhe Aircraft Industries ) developed a copy under the name Z-8 with French support, which was only produced in series from the 1990s . This was continuously improved and today forms the basis for civil version AC313 . At the end of March 1965, Sud Aviation had an SA 310 on the Sabena route network on a trial basis, which at that time also operated a helicopter fleet. The attempt should shed light on whether the type also had a future as a civilian version.
In France, the last SA 321 was officially decommissioned on April 30, 2010.
