BAe 748 (BAE 748)

 

Short-haul turboprop aircraft BAe.748, better known as the Hawker Siddeley HS.748 or as Avro 748, is a multi-purpose aircraft, developed by the British Aircraft Company «Avro Aircraft», to replace the American twin-engine piston aircraft Douglas DC-3.

Work on the Avro 748 project began in 1957. As the basis of the aircraft, a monoplane design with a circular fuselage capable of accommodating an average of 40-44 passenger seats and a low-lying wing with two engines was chosen. The main requirements for the aircraft design were the ability to use it at unprepared airfields, be unpretentious and easy to maintain and operate, and also have a short takeoff and landing.

Officially, the program is the construction of the aircraft, Avro748, began in January 9 1959 years.

As the power plant, the Rolls Royce Dart R.Da.7Mk.514 engines with a capacity of 1740 hp, equipped with four-blade propellers, were chosen. Four aircraft were built under the Avro 748 development program. Two of which are for aerial testing and the other two are for ground and static ultimate load testing.

His first flight of the aircraft Avro 748, 24 made June 1960 years. He took off from the airfield of British Woodford (Woodford), located in Cheshire (Cheshire). The first production aircraft Avro 748 Series 1 have been ordered by the airline «Skyways Coach-Air». The first commercial flight airplane Avro 748 April 1 1962 made a year in "London - Paris."

On November 6, 1961, the Avro 748 Series 2 aircraft flew, which was equipped with Rolls Royce Dart RDa.7Mk engines. 531, with a capacity of 2105 hp, and had a higher payload compared to the previous model. This version also became the basic version for subsequent aircraft of the HS.748 family (Avro 748). It allowed to place up to 52 passenger seats in its cabin.

In 1963, the Avro 748 aircraft was renamed HS.748, due to the fact that Avro was bought out by the larger Hawker Siddeley Group.

In June 1967, an improved model of the second series, the HS.748 Series 2A, was released, which was equipped with Rolls Royce Dart RDa.7Mk turboprop engines. 532 with a capacity of 2280 hp, and also had an increased fuel reserve. This version of the aircraft, the HS.748, made its first flight on September 5, 1967.

HS.748 Series 2A enrolled in such airlines as the British "British Airways"African"South African Airways"New Zealand« Mount Cook Airline ». The plane was also raised, and other large and small carriers.

In 1977, work began on the HS.748 Series 2B. This version of the aircraft was powered by Rolls Royce Dart RDa.7Mk turboprop engines. 536-2 2290 hp This engine was better suited for high altitude and hot climates and also had lower noise levels. Effective January 1, 1978, the Hawker Siddeley Group was merged with the British Aerospace consortium. From this point on, the name of the HS.748 Series 2B aircraft was changed to BAe.748.

The first production aircraft took to the skies BAe.748 22 1979 year in June. In the US, the aircraft also were called Intercity-748. This version of the aircraft allowed to carry up to 58 people at an average distance of about 2 thousand kilometers, with an average speed 450 kilometers per hour.

In February 1982 year was presented last modification of aircraft BAe. Super 748 with engines Rolls Royce Dart RDa.7Mk.552. In this version has been increased luggage space, improved interior of the passenger compartment, as well as enhanced control and navigation. This turboprop airliner made its first flight in July 30 1984 years.

Aircraft of the BAe.748 (HS.748) family were produced in various versions - from civil and transport to military. Production of BAe.748 aircraft was halted in May 1988 with the introduction of more modern aircraft models. In total, for the entire production period from 1961 to 1988, about 380 units of the BAe.748 (HS.748) aircraft were produced
