Boeing 767

The creation of variants of the Boeing Model 767 and 757 was announced at the same time, however, the first of them had a fuselage that was 1.24 m wide, which made it possible to arrange seats seven or eight in a row with two aisles. Possible layouts allow placing either 211 passengers in a mixed class cabin (18 – in a first-class cabin with six seats in a row and 193 passengers in a tourist class cabin with seven chairs in a row), or 230 passengers in a tourist class cabin with seats for seven in a row, or the maximum number of 289 passengers – eight seats in a row; There are other layout options. An order was received for 30 aircraft from United Airlines. In March 1990 the total number of orders and options was 483 cars.

To speed up the preparation of drawings for most of the power structure, the automated design was used, which allowed achieving high accuracy, which is very important when a large percentage of design work is carried out by other companies. A total of 28 companies produce components and assemblies, the cost of which is 45 percent of the total cost of the aircraft. The wing structure is characterized by increased sweep, span, and chord, which increases the wing area by approximately 53 percent. The tail and chassis of both options have a similar configuration; Boeing 767 aircraft are equipped with two turbofan engines suspended on pylons under the wing. Either Pratt & Whitney JT9D-7R4D engines or General Electric CF6-80A engines, each of which belongs to the class of engines with a thrust of 21772 kg, can be installed. Along with the Rolls-Royce RB211 engine, later versions of the General Electric and Pratt & Whitney engines are offered.

Initially, Boeing planned to offer two options: the Boeing 767-100 with a shortened fuselage, designed for 180 passengers, and the main version of the Boeing 767-200, described above. Then it was decided, instead of the first option, to release option 767-200 with various flight weights. So, the option that was originally ordered by United Airlines for use on US domestic airlines has a maximum take-off weight of 127913 kg. With a total weight of 140,614 kg, it can carry 211 passengers at a distance of 6013 km, which makes it suitable for non-stop transcontinental flights. The crew of the aircraft, consisting of two or three people, has at its disposal the same electronic equipment as on option 757. The new airliner provides a 32 percent reduction in the cost of a passenger-mile compared to other wide-body aircraft equipped with three turbojet engines. The new fuselage design provides greater payload. The cargo compartment of the aircraft can hold up to 22 LD-2 containers or LD-3 / -4 / -8 containers, which occupy a similar volume. Thanks to the additional front hatch of the cargo compartment, the dimensions of which are 1.75 m 3.4 m, Type 2 containers can be loaded.

The first Boeing 767 was launched in Everett, Washington on August 4, 1981, and made its first flight there lasting 2 hours 4 minutes on September 26. In February 1983, Boeing announced the creation of the 767-300 variant, whose fuselage was lengthened by 6.42 m, which allowed to increase capacity. Both the 767-200 and 767-300 are offered in the ER (Extended Range) version with an increased flight range with an increased fuel tank volume and take-off weight.
