Boeing 737-200 v2 ~ Tinmouse II

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far exceeded that of the shorter -100 and the 737-200 remained in production until 1988, by which time it had been superseded by the improved 737-300, after 1114 had been built.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.

 

 

 

 

 

NAMC YS-11 ~ AFG

The only Japanese airliner to enter production since WW2, the YS11 achieved a degree of success in its domestic market and in North America.

The YS11 was a product of the Nihon Aircraft Manufacturing Company (or NAMC), a consortium of Fuji, Kawasaki, Mitsubishi, Nippi, Shin Meiwa (now Shin Maywa) and Showa. NAMC formed on June 1 1959 to design and develop a short to medium range airliner, with particular attention being paid to meeting the specific operating requirements of the Japanese domestic airlines.

NAMC selected the RollsRoyce Dart over the Allison 501 to power the new airliner. Fuji was given responsibility for the tail unit, Kawasaki the wings and engine nacelles, Mitsubishi the forward fuselage and final assembly, Nippi the ailerons and flaps, Shin Meiwa the rear fuselage and Showa the light alloy honeycomb structural components.

The YS11 first flew on August 30 1962 (a second prototype flew that December), and was awarded Japanese certification in August 1964. By that time the first production aircraft were under construction, and the type entered service with Toa Airways (now JAS) in April 1965. Initial production was of the YS11100, the follow up YS11A200 (first flight November 1967) was designed for export markets and featured an increased max takeoff weight. The YS11A300 was a combi passenger/freight model, while the YS11A400 was a pure freighter with a forward freight door.

The YS11A500, 600 and 700 were equivalent to the 200, 300 and 400, but with a 500kg (1100lb) greater max takeoff weight. Production ceased in February 1974.

By late 1998 66 YS11s remained in commercial service. The largest operators were All Nippon (6) and Japan Air Commuter (12).
