Quick to pick up on demand for such an aircraft, manufacturers on both sides of the Atlantic (as well as beyond) were keen to benefit. Airliners.net is the leading community for discovering and sharing high-quality aviation photography. The avionics were also to have triplicated components for reliability and to allow "majority 2:1 voting" for aircraft guidance during automatic approach and landing. Hawker Siddeley Aviation, which had absorbed de Havilland, needed additional customers for the Trident, so entered into discussions with American Airlines (AA) in 1960. [42] By 1965, 15 Tridents were in BEA's fleet, and by March 1966, the fleet had increased to 21. AA requested greater range than what the aircraft initially had, which meant that the original DH121 design would have fulfilled its requirements almost perfectly.

BEA bought 15,[50] while two were bought by Cyprus Airways. The Hawker Siddeley Trident's demise came about in the early 1980s after the International Civil Aviation Organization (ICAO) demanded older jets be fitted with hush kits to reduce aircraft noise.
WebHawker Siddeley HS-121 Trident. May 15, 2021. To the casual bystander, the external differences between the Boeing 727 and the Trident may go unnoticed. Eastern Airlines was also a significant potential customer; between these two companies, 80 aircraft were required. The Trident was subsequently ordered into production in August 1959, having been selected from various proposals submitted by the British aerospace companies Avro, Bristol, and de Havilland. Larger fuel tanks were added to the Trident 3B, extending the aircraft's range by 430 miles. By 1960 de Havilland had been taken over by the Hawker Siddeley Group, who renamed the DH.121 the HS 121. The Trident originated as the de Havilland DH121, proposed in 1956 to meet a requirement by British European Airways for a fast short and medium-range aircraft to accommodate 100 passengers. After having come to market sooner, sales of the Boeing 727 surpassed that of the Trident, and by 1975 1,000 Boeing 727s had been sold against 117 Tridents. FlightGlobal is the global aviation communitys primary source of news, data, insight, knowledge and expertise.

While referencing, the Trident's rearmost cockpit side window sloped downwards to the rear, whereas the 727s side cockpit windows were more angular in design. Since Tridents could operate safely to airfields equipped with suitable ILS installations, they could operate schedules regardless of weather, while other aircraft were forced to divert.[47].

To cater to BEA's needs, Vickers developed the Vanguard. This would ultimately allow operations in almost zero visibility. [9] During the time that the DH.121 had emerged in the late 1950s, the British government came to view the airframe and aeroengine industries as too fragmented into small companies; accordingly, a policy favouring mergers into a few large groups was adopted. [9][21], In April 1958, de Havilland firmed the general configuration of the DH.121 and established a development timetable, including a projected date for the type's maiden flight to be conducted during mid-1961. WebThe Hawker Siddeley HS 121 Trident was a British short and medium-range airliner developed by Hawker Siddeley.

The Boeing 727 family was a massive success for the Boeing Company, selling 1,831 units in total and becoming the most popular commercial aircraft it had produced at that time. De Havilland was keen to retain their independence and leadership of the DH.121, so approached the government with a proposal to form a consortium under which de Havilland would produce the fuselage, Bristol would manufacture the wings, and various other companies, including Hunting Aircraft and Fairey Aviation, would be responsible for other elements; however, Bristol strongly opposed this arrangement and chose to work with Hawker Siddeley in competition against de Havilland. What does the future of aviation look like in 2022? The two designs had a similar layout, the 727 being slightly larger. The aircraft were ferried back to the manufacturer and repaired, then returned to service. [38] Rolls-Royce Limited, having shelved development of the Medway following the Trident's redesign, was keen to develop an engine to slot between the 10,000lb Spey engine and the 20,000lb Rolls-Royce Conway engine; if such an engine had been produced, it could have equipped new versions of the civil Trident, as well.

We will look at each aspect of these differences in turn, starting with capacity, followed by each model's leading performance and technical specifications, powerplants, orders, and finally, the critical external differences between the two. At one point, American Airlines had shown significant interest in the Trident, although it required various modifications to the design to make the aircraft fit for its purposes.

In emergency descents of up to 10,000ft/min, it was permissible to use reverse thrust. Its designers felt this configuration offered a trade-off between cruising economy and take-off safety in case of an engine failure; moreover, the BEA specification had called for "more than two engines". The American carrier demanded a plane with a greater range than the Trident had, encouraging Hawker Siddeley to incorporate engine modifications and larger wings for added fuel capacity. [16] Notably, de Havilland had not yet secured a formal and final BEA order and its competitor Bristol was actively promoting their 200 [N 2] project, which was significantly smaller than the DH.121. The airliner was initially known as the DH121, conceived by the De Havilland Aircraft Company.

This, combined with more powerful engines and increased take off weight, allowed the type to offer both a greater passenger capacity and longer range. While developed mainly in parallel to the same requirements from airlines at the same time, there were some key differences between the two models. [24], Although de Havilland stated that they generally concurred with BEA, its management also stated that they had worked "under terms more onerous than anything D.H. had previously undertaken".
