Report :a320
The Airbus A320 family is a family of short- to medium-range, narrow-body, commercial passenger jet airliners manufactured by Airbus Industrie The family includes the A318, A319,A320 and A321, as well as the ACJ business jet. Final assembly of the family in Europe takes place in Toulouse, France and Hamburg, Germany; since 2009, a plant in Tianjin, People's Republic of China has also started producing aircraft for Chinese airlines. The aircraft family can accommodate up to 220 passengers and has a range of 3,100 to 12,000 km (1,700 to 6,500 nmi), depending on model.
The first member of the A320 family—the A320—was launched in March 1984, first flew on 22 February 1987, and was first delivered in 1988. The family was soon extended to include the A321 (first delivered 1994), the A319 (1996), and the A318 (2003). The A320 family pioneered the use of digital fly-by-wire flight control systems, as well as side stick controls, in commercial aircraft. Although there has been a continuous improvement process since introduction, the proposed A320neois to offer new, more efficient engines.
As of 30 June 2011, a total of 4,728 Airbus A320 family aircraft have been delivered, of which 4,638 are in active service. In addition, another 2,834 airliners are on firm order. According to Airbus, it ranked as the world's fastest-selling jet airliner family according to records from 2005 to 2007, and as the best-selling single-generation aircraft programme. The family's direct competitors are the Boeing 737, 717 and 757.
Design effort
A new programme was initiated subsequently, called Joint European Transport (JET). This was set up in June 1977, and was based at the then British Aerospace (formerly Hawker Siddeley) site in Weybridge, Surrey, UK. Although the members were all of Airbus' partners, they regarded the project as a separate collaboration from Airbus. This project was considered the forerunner of Airbus A320, encompassing the 130- to 188-seat market, powered by two CFM56s.It would have a cruise speed of Mach 0.84 (faster than B737). The programme was later transferred to Airbus, leading up to the creation of the Single-Aisle (SA) studies in 1980, led by former leader of JET programme, Derek Brown. The group looked at three different variants, covering the 125- to 180-seat market, called SA1, SA2 and SA3. Although unaware at the time, the consortium was producing the blueprints for the A319, A320 and A321, respectively. The single-aisle programme created divisions within Airbus about whether to design a shorter-range twinjet than a longer-range quadjet wanted by the West Germans, particularly Lufthansa. However, works proceeded, and the German carrier would eventually order the twinjet.
Further shrinking
The A318 was born out of mid-1990 studies between Aviation Industries of China (AVIC), Singapore Technologies Aerospace, Alenia and Airbus on a 95- to 125-seat aircraft project. The programme was called the AE31X, and covers the 95-seat AE316 and 115- to 125-seat AE317. The former would have an overall length of31.3 m (102 ft 8 in), while the AE317 is longer by 3.2 m (10 ft 6 in), at 34.5 m (113 ft 2 in). The engines would be supplied from two BMW Rolls-Royce BR715s, CFM56-9s, or the Pratt & Whitney PW6000s; with the MTOW of 53.3 t (118,000 lb) for the smaller version and 58 t (130,000 lb) for the AE317, the thrust requirement were 77.9–84.6 kN (17,500–19,000 lbf) and 84.6–91.2 kN (19,000–20,500 lbf), respectively.[60] Range was settled at 5,200 km (2,800 nmi) and 5,800 km (3,100 nmi) for the high gross weights of both variants.[60] Both share a wingspan of 31.0 m (101 ft 8 in)[60] and a flight deck similar to that of the A320 family. Costing $2 billion, €1.85 billion to develop, aircraft production to take place in China.
Simultaneously, Airbus was developing Airbus A318. In early 1998, Airbus revealed its considerations of designing a 100-seat aircraft based on the A320; by September 1998, the project AE31X terminated, after which Airbus officially announced an aircraft of its own, the A318,[61] at that year's Farnborough Airshow. The aircraft is the smallest, or "baby", of the A320 family, and therefore the smallest Airbus. Ironically, it was developed at the same time as the largest commercial aircraft in history, the Airbus A3XX (later renamed Airbus A380). First called A319M5 in as early as March 1995, it was shorter by 0.79-metre (2 ft 7 in) ahead of the wing and 1.6 metres (5 ft 3 in) behind. These cuts reduced passenger capacity from 124 on the A319 to 107 passengers in a two-class layout. Range was 3,350 kilometres (1,810 nmi), or 6,850 kilometres (3,700 nmi) with upcoming sharklets.
The 107-seater was launched on 26 April 1999 with the options and orders count at 109 aircraft. After three years of design, the maiden flight came on 15 January 2002, when the prototype took off at Hamburg at 10:11 local time, returning 3 hours and 44 minutes later at 13:55. Tests on the lead engine, the Pratt & Whitney PW6000, revealed worse-than-expected fuel consumption. Consequently, Pratt & Whitney abandoned the five-stage high pressure compressor (HPC) for the MTU-designed six-stage HPC. The 129 order book for the A318 shrunk to 80 largely because of switches to other A320 family members. After 17 months of flight certification, during which 850 hours and 350 flights were accumulated, JAA certification was obtained for the CFM56-powered variant on 23 May 2003. On 22 July 2003, first delivery for launch customer Frontier Airlines occurred, entering service before the end of the month.
