Airbus Beluga
https://en.wikipedia.org/wiki/Airbus_Beluga
The Airbus A300-600ST (Super Transporter) or Beluga, is a version of the standard A300-600 wide-body airliner modified to carry aircraft parts and oversized cargo. It received the official name of Super Transporter early on; however, the name Beluga, a whale it resembles, gained popularity and has since been officially adopted. The Beluga XL, based on the Airbus A330 with similar modifications and dimensions, is being developed by Airbus to replace the type around 2020. Super Guppies grew increasingly unsatisfactory for Airbus's ferrying needs: their age meant that operating expenses were high and ever-increasing, and growing Airbus production required greater capacity than could be provided by the existing fleet. A speedy development program was also necessitated in order to begin introducing the prospective type in time to take over duties from the Super Guppy fleet, which was scheduled to draw down in the mid-1990s. In August 1991, Aérospatiale and DASA, two of the major Airbus partners, formed a 50/50 joint venture company, Super Airbus Transport International (SATIC), based in Toulouse, France, to develop a new-build replacement for the Super Guppy fleet. The selected starting point for the design was the Airbus A300, leading to the new airframe being designated as the A300-600ST Super Transporter. The A300-600ST Beluga shares many design similarities, although substantially differing in appearance, to the Airbus A300 it was based upon. The wings, engines, landing gear, and the lower part of the fuselage remain identical to those used on the conventional A300, while the upper part of the fuselage forms an enormous horseshoe-shaped structure 7.7 m (25 ft) in diameter. In comparison with the Super Guppy, the payload was more than doubled and the volume increased by more than 30 per cent. The General Electric CF6-80C2 turbofan engines used are slightly uprated from those used on the standard A300 as well. The vertical stabilizer uses a modified Airbus A340 fin with a 1.12 m (3 ft 8 in) base extension while the tailplane was strengthened and fitted with auxiliary fins to maintain directional stability. To provide access to the cargo area from the front without having to disconnect all electrical, hydraulic and flight control connections (and also avoiding the lengthy recalibrations before each flight that reconnection entailed), the standard A300 cockpit was relocated down below the cargo-floor level. By relocating the cockpit in this manner, loading times were reportedly halved from those encountered using the Super Guppy, which had needed to disconnect and reconnect such systems. Another reason for faster loading times was the adoption of a roll-on/roll-off loading system, as well as the ability to unload the aircraft in winds of up to 40 knots. The qualities and improved capabilities of the Beluga resulted in the costs associated with transporting Airbus components dropping to only one-third of those achieved by the Super Guppy. The cockpit of the Beluga is pressurized but the cargo deck is not, making it inaccessible during flight and unsuitable for cargoes that require a pressurized environment, such as live animals. However, the cargo deck is fitted with a heating module to keep the cargo within an appropriate temperature range. On at least one occasion, a pressurized container has been used for cargo (see Operational history). The aircraft is operated by a crew of three – two pilots and a loadmaster. The main deck cargo volume of the Beluga is greater than that of the C-5 Galaxy or the Antonov An-124 but still smaller than Antonov An-225. However, it is restricted by cargo-weight capacity of 47 tonnes, compared to 122.5 tonnes for the C-5 Galaxy and 150 tonnes for the An-124. Despite this width, the Beluga cannot carry most fuselage parts of the Airbus A380, which are instead normally transported by ship and road. The Beluga has been used to transport some A380 components. Role Outsize cargo freight aircraft Manufacturer Airbus First flight 13 September 1994 Introduction September 1995 Status In service Primary user Airbus Transport International Produced 1992–c.1999 Number built 5 Unit cost $285 million Developed from Airbus A300-600 In January 1996, the Beluga was formally placed into dedicated service, ferrying components from various aerospace sites to the final assembly lines in Toulouse, France and Hamburg, Germany. On 24 October 1997, the last of Airbus Industrie's Super Guppy freighters was retired and its outsize cargo mission from that point onwards being exclusively performed by the new A300-600ST fleet. In 1997, the second year of Beluga operations, the fleet accumulated in excess of 2,500 flight hours across more than 1,400 flights. By 2012, the fleet was performing roughly 5,000 flight hours per year; Airbus expected this figure to double by 2017. Since entering service, the Beluga has been subject to several infrastructure upgrades. In 2011, Pau Pyrénées Airport, a site routinely visited by Belugas, became the first airport in Europe to deploy the European Geostationary Navigation Overlay Service, which accurately guides the Beluga and other aircraft during landing. In 2015, a dedicated Beluga loading station was opened at Hawarden Airport, preventing high winds from disrupting future operations. In June 1997, a world record was set for the most voluminous payload to be carried by an aircraft when a Beluga was used to transport a chemical tank for a merchant vessel from Clermont-Ferrand to Le Havre, France. In February 2003, a single Beluga performed the farthest distance charter flight ever, having flown for 25 hours (not including refueling stops) to transport two complete NHI NH90 helicopters along with a single Eurocopter Tiger attack helicopter from Marseille, France to Melbourne, Australia, for the Avalon Airshow.
