History

The 737-600 and -700 are the smaller members of Boeing's successful Next Generation 737-600/700/800/900 family.

Among the many changes, the Next Generation 737s feature more efficient CFM56-7B turbofans. The CFM56-7 combines the core of the CFM56-5 with the CFM56-3's low pressure compressor and a 1.55m (61in) fan. The 737's new wing has greater chord, span and wing area, while the tail surfaces are also larger. The 2.4m (8ft) high winglets first developed for the Boeing Business Jet development are now offered as an option on the 737-700 (and -800).

The new engines and wings allow the 737 to cruise at Mach 0.78 to Mach 0.80, while the larger wing allows greater fuel tankage and transcontinental USA range. Other features include a 777 style EFIS flightdeck with six flat panel LCDs which can be programmed to present information as on the 777 or as on the 737-300/400/500 series, allowing a common pilot type rating for the two 737 families.

The improved Next Generation Boeing 737 family (originally covered by the 737X designation) was launched in November 1993. The 737-700 was the first member of the new family to be developed, and is based on the 737-300, while the 737-600 is based on the 737-500.

The 737-700 rolled out on December 7 1996, was granted certification in November 1997 and entered service (with Southwest) the following month. The 737-600 was launched was launched on March 16 1996, first flew on January 22 1998 and entered service (with SAS) in September that year.

The Boeing Business Jet or BBJ (described separately) is based on the fuselage of the 737-700 with the larger 737-800's wing.

The BBJ's airframe also forms the basis for the convertible passenger/freighter variant of the 700, the 737-700QC, which has been ordered by the US Navy as the C-40A Clipper (to replace the DC-9 based C-9B). The C-40 first flew on April 17 2000. The naval aircraft can be converted to carry 121 passengers, or 3 pallets of cargo plus 70 passengers, or 8 pallets of cargo only. These aircraft are currently (2002) based at Naval Air Station Fort Worth, Texas (VR-59) and Naval Air Station Jacksonville, Florida (VR-58).

The US Air Force has bought two ex-Fordair BBJs, which are designated C-40B.

Type

Short range narrowbody airliner
History

The 737-100 and 200 are the first generation production models of the world's most successful jet airliner family, Boeing's 737 twinjet.

The 737 was conceived as a short range small capacity airliner to round out the Boeing jet airliner family beneath the 727, 720 and 707. Announced in February 1965, the 737 was originally envisioned as a 60 to 85 seater, although following consultation with launch customer Lufthansa, a 100 seat design was settled upon. Design features included two underwing mounted turbofans and 60% structural and systems commonality with the 727, including the same fuselage cross section (making it wider than the competing five abreast DC-9 and BAC-111).

The 737-100 made its first flight on April 9 1967 and entered service in February 1968 with Lufthansa, while the last of 30 built was delivered to Malaysia-Singapore Airlines in October 1969.

By this time however the larger capacity 1.93m (6ft 4in) stretched 737-200 was in service after it had made its first flight on August 8 1967. First delivery, to United, was that December.

Developments of the -200 include the -200C convertible and quick change -200QC, while an unprepared airfield kit was also offered. The definitive Advanced 737-200 appeared in 1971, featuring minor aerodynamic refinements and other improvements.

Sales of the 737-200 far exceeded that of the shorter -100 and the 737-200 remained in production until 1988, by which time it had been superseded by the improved 737-300, after 1114 had been built. Many have been fitted with Stage 3 engine hushkits, and a number of passenger aircraft have been converted with cargo doors.

The USAF ordered 19 as navigation trainers, and some were later converted to standard transport aircraft as CT-43A. A few other air forces received 737-200s to serve in general transport, surveillance or VIP transport tasks.

History

The 707's jet speed, long range, high seating capacity and operating economics revolutionised airliner travel when it was introduced into service in 1958. The 707 also laid the foundations for Boeing's dominance of the jet airliner market.

Recognising the jet engine's potential for commercial aviation, Boeing (at great financial risk) decided to develop a jet powered transport that could fulfil military tanker transport roles but be easily adapted to become an airliner. The resulting prototype, known as the 367 Dash 80, flew for the first time on July 16 1954. Impressed, the US Air Force ordered a larger version, with a wider fuselage (12 ft, vs 11 ft for the Dash 80) into production as the KC-135 tanker/transport (more than 800 were built). At first, Boeing wanted to sell the same size aircraft to the airlines, but the airlines insisted on an even larger airplane, which Douglas promised to build (this became the DC-8). Boeing finally relented, designing the 707 as a longer aircraft with a slightly wider fuselage (12 ft 4 in).

The first production 707 (a 707-120 for Pan Am) flew on December 20 1957, and entered service later the following year. Developments of the 707-120 include the similar 707-220, the shorter 138 for Qantas, and the stretched 707-320, which flew in July 1959. The 707-120 and 320 were later reengined with JT3D turbofans (in place of the original JT3 and JT4 turbojets) to become the 707-120B, and the 707-320B respectively. The 707-320C was a convertible model, the 707-420 was powered by RollsRoyce Conways, while the proposed CFM-56 powered 707-700 upgrade was flight tested in the late 1970s but never entered production.

Most civil 707s in service today have been converted to freighters, while a number are used as corporate transports.

Many air forces have bought 707s, new or converted second-hand aircraft, for general transport, aerial refuelling, and electronic warfare. The E-3 Sentry is a dedicated airborne warning and control system (AWACS) platform with a large rotodome above the fuselage. The E-6 Mercury performs the TACAMO (Take Charge and Move Out) role with the US Navy, maintaining communication with the ballistic missile submarines. The E-8 J-Stars (Joint Surveillance Target Attack Radar System) performs the battlefield control role. Other military 707s received the designations C-137, or C-18, but many others have no special military designation.

History

The A330-300 is the biggest member of Airbus' twinjet family and is closely related to the four engined long range A340 with which it shares near identical systems, airframe, flightdeck and wings, the only major difference being the twin (versus four) engine configuration.

The A340 and A330 were launched simultaneously in June 1987. Although developed in parallel the A330-300 made its first flight after the A340, on November 2 1992. It was the first aircraft to achieve simultaneous European Joint Airworthiness Authorities (JAA) and US FAA certification, on October 21 1993. Entry into service took place by the end of that year.

Differences from the A340 aside from the number of engines are slight changes to the wing and internal systems, including fuel tankage. The A330 (like the A340) takes advantage of a number of technologies first pioneered on the A320, including the common advanced EFIS flightdeck with side stick controllers and flybywire computerised flight control system.

While the standard A330-300 shares the same fuselage length as the A340-300, Airbus has studied various stretched (A330-400) and shortened (A330-100 and 200) versions. The shortened A330-200 was formally launched in 1996 as a long range 767-300ER competitor, and is described separately. One stretched, high capacity concept studied for a time featured lower deck seating in place of the forward freight hold.

Long range widebody airliner
Schematics

History

The A330-200 is the newest member of Airbus' widebody twinjet family and is a long range, shortened development of the standard A330, developed in part as a replacement for the A300-600R and a competitor to the 767-300ER.

Airbus launched development of the A330-200 in November 1995, followed by the first customer order, for 13 from ILFC, placed in February 1996. First flight was on August 13 1997, with certification and first customer deliveries,to ILFC/Canada 3000, in April 1998.

The A330-200 is based on the A330-300 and shares near identical systems, airframe, flightdeck and wings, the only major difference being the fuselage length. Compared with the 300 the A330-200 is 10 frames shorter, and so has an overall length of 59.00m (193ft 7in), compared with 63.70m (209ft 0in) for the standard length aircraft. This allows the A330-200 to seat 256 passengers in a three class configuration, or alternatively 293 in two classes.

Because of its decreased length the A330-200 features enlarged horizontal and vertical tail surfaces (to compensate for the loss of moment arm with the shorter fuselage). Another important change is the addition of a centre fuel tank, which increases the A330-200's fuel capacity over the 300's, and results in the 200's 11,850km (6400nm) range.

Like the A330, engine options are the GE CF6-80, Pratt & Whitney 4000 series and the RollsRoyce Trent 700.

The A330-200 has sold quite strongly since its launch. Among the initial A330-200 customers are, apart from ILFC, Canada 3000, Korean Air, Austrian, Air Transat, Emirates, Swissair, Sabena, Monarch, Asiana, TAM, and Air Lanka.
