Developed into Concorde

The Bristol Type 223 was an early design for a supersonic transport. In the late 1950s and early 1960s the Bristol Aeroplane Company studied a number of models as part of a large British inter-company effort funded by the government. These models eventually culminated in the Type 223, a transatlantic transport for about 100 passengers at a speed around Mach 2. At about the same time Sud Aviation in France was developing the similar Super-Caravelle design, and in November 1962 the efforts were merged to create the Concorde project.

Development

Background

In the UK, as elsewhere in the 1950s, the aero industry had been producing a series of supersonic test aircraft and had extensively studied the problems of sustained high-speed flight. By the mid-1950s, two designs had been shown to have a lift-to-drag ratio suitable for supersonic cruise, a sharply swept M-wing pioneered at Armstrong-Whitworth for slightly supersonic flight and very slender delta wings suitable for a wide range of speeds. Higher speeds up to Mach 3 had been considered and found to be possible, but it appeared that a practical upper limit was Mach 2.2; above this speed the duralumin used for most aircraft construction would start to soften due to the heat of friction, and some new material would have to be used instead. [1] Stainless steel was considered, but the Bristol 188 proved this to be difficult and expensive.

STAC

By 1956 there was enough official interest in this research for the Supersonic Transport Aircraft Committee, or STAC, to be formed under Sir Morien Morgan to investigate the creation of a supersonic transport. Its first report, in 1959, recommended two designs. One was an M-wing Mach 1.2 medium range airliner and the other a straight wing, Mach 1.8 design with six wingtip engines. Soon after, however, studies at the Royal Aircraft Establishment began to favour the gothic delta and design contracts using this planform went to Hawker Siddeley and Bristol in late 1959. Both were asked to look at both Mach 2.2 aluminium alloy and Mach 2.7 stainless steel structures. [2] Bristol's Mach 2.7 design was labelled the Type 213. Their designer, Archibald Russell, was influenced by the constructional problems and expense encountered with the Bristol 188 and favoured the lower speed alloy aircraft. [3]

The thin wing design of the Type 213 was preferred by the STC and a 1961 contract encouraged a detailed series of studies of a 130-seat, Mach 2.2 aircraft powered by six Bristol Olympus engines under the generic Type 198 label. Aware of the great expense of the project, STAC required Bristol to share the cost with an overseas partner. In 1961, Sud Aviation revealed their plans for the Super-Caravelle at the Paris Air Show, a smaller aircraft than the Type 198. Bristol proposed a design which came between the Super Caravelle and the Type 198 which they called the Type 223; the French were looking at a slightly larger version of the Super Caravelle and the two companies had a specification for agreement to build an aircraft jointly. Throughout 1962 they and their respective governments negotiated the formation of a consortium to share development and production costs, estimated at £15m-£170m. [2] [ clarification needed ] On 29 November 1962 an agreement was jointly signed by the UK Minister for Aviation, Julian Amery and the French ambassador, Geoffrey de Courcel and the Concorde project was underway.

The Aérospatiale/BAC Concorde is a retired Franco-British supersonic airliner jointly developed and manufactured by Sud Aviation and the British Aircraft Corporation (BAC). Studies started in 1954, and France and the UK signed a treaty establishing the development project on 29 November 1962, as the programme cost was estimated at £70 million . Construction of the six prototypes began in February 1965, and the first flight took off from Toulouse on 2 March 1969. The market was predicted for 350 aircraft, and the manufacturers received up to 100 option orders from many major airlines. On 9 October 1975, it received its French Certificate of Airworthiness, and from the UK CAA on 5 December.

The Bristol Aeroplane Company, originally the British and Colonial Aeroplane Company, was both one of the first and one of the most important British aviation companies, designing and manufacturing both airframes and aircraft engines. Notable aircraft produced by the company include the 'Boxkite', the Bristol Fighter, the Bulldog, the Blenheim, the Beaufighter, and the Britannia, and much of the preliminary work which led to Concorde was carried out by the company. In 1956 its major operations were split into Bristol Aircraft and Bristol Aero Engines. In 1959, Bristol Aircraft merged with several major British aircraft companies to form the British Aircraft Corporation (BAC) and Bristol Aero Engines merged with Armstrong Siddeley to form Bristol Siddeley.

<span class="mw-page-title-main">Supersonic transport</span> Type of commercial airliner (SST)

A supersonic transport (SST) or a supersonic airliner is a civilian supersonic aircraft designed to transport passengers at speeds greater than the speed of sound. To date, the only SSTs to see regular service have been Concorde and the Tupolev Tu-144. The last passenger flight of the Tu-144 was in June 1978 and it was last flown in 1999 by NASA. Concorde's last commercial flight was in October 2003, with a November 26, 2003 ferry flight being its last airborne operation. Following the permanent cessation of flying by Concorde, there are no remaining SSTs in commercial service. Several companies have each proposed a supersonic business jet, which may bring supersonic transport back again.

The Lockheed L-2000 was Lockheed Corporation's entry in a government-funded competition to build the United States' first supersonic airliner in the 1960s. The L-2000 lost the contract to the Boeing 2707, but that competing design was ultimately canceled for political, environmental and economic reasons.

Supercruise is sustained supersonic flight of a supersonic aircraft without using afterburner. Many supersonic military aircraft are not capable of supercruise and can only maintain Mach 1+ flight in short bursts with afterburners. Aircraft such as the SR-71 Blackbird are designed to cruise at supersonic speed with afterburners enabled.

The Sud Aviation Super-Caravelle was an early design for a supersonic transport. Unlike most competing designs which envisioned larger trans-Atlantic aircraft and led to the likes of the Boeing 2707, the Super-Caravelle was a much smaller, shorter range design intended to replace Sud Aviation's earlier and successful Caravelle. Design work started in 1960 and was announced in 1961 at the Paris Air Show, but was later merged with similar work at the British Aircraft Corporation to create the Concorde project in November 1962. After work had begun on designing Concorde, the Super Caravelle name was instead used on a lengthened version of the original Caravelle design, the SE-210B.

A supersonic aircraft is an aircraft capable of supersonic flight, that is, flying faster than the speed of sound. Supersonic aircraft were developed in the second half of the twentieth century. Supersonic aircraft have been used for research and military purposes, but only two supersonic aircraft, the Tupolev Tu-144 and the Concorde, ever entered service for civil use as airliners. Fighter jets are the most common example of supersonic aircraft.

Avro subsequently decided to modify the design of the proposed 730 in order to accommodate its arming with nuclear weapons; this change therefore meant that the type would be able to perform the nuclear weapons delivery mission as well, which had been called for under Air Ministry Specification RB.156T which sought a high speed reconnaissance-bomber aircraft.
