The aircraft model takes Iran Airlines A330 aircraft as the prototype and is produced according to the actual size of the aircraft by scaling-down (1:397). The fuselage and bracket are made of zinc alloy die casting, and the base is made of transparent plastic, in the production process, experienced technicians strictly control it, with fine craftsmanship and vivid image, which is the best product of the same kind!

  Model introduction: Airbus A330 and A340 series are medium-and long-range passenger planes developed and produced by European Airbus Industry Corporation. After analyzing the demand of major airlines in the world for large long-range passenger planes, in January 1986, the company announced the development of two advanced two-aisle wide-fuselage passenger planes. In June 1987, it was decided to launch the A330 and A340 models as a plan at the same time. The concept is: a basic fuselage has the same body cross section, with 2 or 4 engines as the power device, it can provide 6 different configurations covering from 250 to 475 from regional routes to ultra-long routes to improve versatility. The shape of the wing and fuselage of A330 is almost the same as that of A340. The new wing, stabilization device and the new version of the flight control system software are used. In addition to the number of engines and engine-related systems, A330 and A340 two types of machines have great commonality. 85% of the parts can be used with each other. The same body is used, but the length is different, cockpit, wing, tail, landing gear and various systems are the same, which two types of machines retains the high-efficiency fuselage cross-section design of A300/A310 models, and adopts the head that is common to A320 series, cockpit and telex control design can reduce the development cost. The production cost of A330 and A340 models is 2.5 billion US dollars in total (1986 currency value).
  On October 25, 1991, the first model of the project was four pieces long-distance passenger plane A340-300, which took the lead in the first flight and was put into operation in February, 1993. In November 1992, the first model of the A330 series of the dual-engine medium-and-long-range passenger aircraft made its first flight A330-300. Airbus 330/340 series is put into operation, including six basic models: dual-engine medium-distance passenger machine A330-200/300 and four pieces long-distance passenger machine A340-200/300/500/600. These six types of aircraft adopt Airbus's traditional common design, and the cockpit configuration layout is almost the same. As long as pilots receive the same flight training, they can fly the above six different passenger planes. After a short period of training, pilots can easily change from A330/A340 series to smaller A320 series aircraft and large A380 aircraft. At the same time, this common design also reduces the maintenance cost and the inventory of spare aviation materials, greatly enhancing the flexibility of airlines.


  A330 series aircraft are recognized in the same level market, with leading market share and expanding carrier customer base. As the two-way aircraft with the longest flight range among the Airbus aircraft in active service, A330 has more than 60 customers and operators, with a cumulative flight time of more than 5 million hours. In the end, A330 occupied the leading position in the market of intermediate double-engine passenger aircraft in the competition with Boeing 767.
        
  A330 aircraft meets the market demand more closely in terms of range and benefits, and continues to use high-level technologies in terms of structure, aerodynamic performance and system. A330 series aircraft adopts lighter and higher strength metal alloy and composite materials, which can reduce the weight of the aircraft body and improve the life of the aircraft body. In addition, the wing has also been optimized in terms of aerodynamic performance, which ensures the best take-off and landing performance under all conditions and improves the fuel efficiency when the aircraft flies at cruise speed. With advanced wings, high-efficiency engines and a large number of ultra-light alloy and composite materials, the fuel consumption per kilometer and the direct use cost of each aircraft have greatly decreased. As a formal member of Airbus telex control airplane series, the difference between A330 and A340 of four pieces is only a slight difference between the engine control devices installed on the central platform. The pilot qualifications of these two kinds of aircraft are used together. Support Cross Crew Qualification or Mixed Fleet Flying function, depending on the aircraft model when the Crew changes.
  Wing: The wing of A330 is a computer-controlled variable camber wing.

Sweep angle (25% chord length) 30 degrees. The computer operates the trailing edge flap of the aircraft to obtain the best airfoil according to the height, speed and load conditions during flight. This automatic variable camber airfoil can improve the aerodynamic efficiency of the aircraft, reduce the resistance, relieve the load on the wing and reduce the weight of the wing structure, and install the wing tip wings. The lift-drag ratio is 40% higher than A300. The fuselage and tail adopt a large number of aluminum-lithium alloy and composite materials, and aluminum-lithium alloy is used for fuselage structure, flitch and other components. The tail, each control surface, rectifying foreskin and cabin floor are all made of composite materials. The main landing gear is four-wheel trolley type, and the front landing gear is double wheeled. The engine CF6-80, PW4000 or Trent 700 selected by the power plant adopts advanced technology, with higher compression ratio, increasing the intake port and air volume, improving engine thrust and reducing fuel consumption. All meet the ETOPS180 minute standard. The cockpit is a two-person driving system, which is developed from the A320 advanced cockpit and is operated by side bars. There are 6 color multifunctional monitor on the main dashboard, and all performance data are displayed digitally. Not only is it equipped with flight management system and electronic flight instrument system, but also the center of gravity management system of the aircraft is added.
