[29] In September 1960, the future airliner's name, Trident, was announced at the Farnborough Airshow; this name had been chosen as a reflection of its then-unique three-jet, triple-hydraulic configuration.[30]. [15] The company's market research department was forecasting that as many as 550 airliners in its category would be sold by 1965.

Hawker Siddeley offered two new designs in 1965: a larger 158-seat two-engine aircraft otherwise similar to the Trident known as the HS132; and the 185-seat HS134, which moved the engines under the wings, a design very similar to the Boeing 737. [16], On 12 February 1958, the British government authorised BEA to commence contractual negotiations along with the issuing of a letter of intent for 24 aircraft. The fourth stall test was made at an altitude of 11,600 ft in the landing configuration and with the stall warning and recovery systems inoperative.

The angle at which this occurs is called the critical angle of attack.Air flow separation begins to occur at small angles of attack while attached flow over the wing is still dominant. It was the first T-tail rear-engined three-engined jet airliner to be designed. British United, British Caledonian Vickers VC10. 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 then proposed an improved 1C, the Trident 1E. [41] Due to a desire to cut costs, though, the RAF decided to issue an entirely new operational requirement, under which the demands for speed, endurance, and capacity had all been diminished.

Before the aircraft took to the air, a reorganization of the British aircraft industry saw De Havilland merge into Hawker Siddeley Group. HAWKER SIDDELEY HS-121 TRIDENT (UK) Boeing 727 (USA) Tu-154 (USSR) Il-74 (USSR) The Hawker Siddeley HS 121 Trident (originally the de Havilland D.H.121 and the Airco DH 121) was a British short and medium-range airliner. B-744-SMZ. All versions were powered by versions of the Rolls-Royce Spey, while the boost engine was a Rolls-Royce RB162, originally intended as a lift engine for VTOL applications. De Havilland se tak angaoval na poli vvoje Since the Spey 512 was the last of the Spey line, extra thrust would be difficult to obtain. This was the last production variant of the 727 to be developed by Boeing, and 15 aircraft were built, all for Federal Express; the last 727 aircraft completed by Boeing was a 727-200F Advanced. It had three rear-mounted engines: two in side-fuselage pods, and the third in the fuselage tailcone, with an S-shaped intake duct. He recalls that while the Trident was not a sparkling performer on the ground, the high Mach number behaviour was fantastic. 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. [15] Accordingly, that same month, BEA announced that the DH.121 had come closest to its requirements and that it would proceed to order 24 with options on 12 more. British airliner produced by Hawker Siddeley. This gave the aircraft the 15% increase in take-off power needed to avert critisism and the first HS121 Trident 3B flew on 11 th December 1969. In the 1980s the Boeing 727 was discontinued, as its central engine bay would require a prohibitively expensive redesign to accommodate quieter high-bypass turbofans, and it was soon supplanted by twinjets for the narrow-body market; Airbus with the A320, and Boeing with the 757 and updated "classic" variants of the 737. Revell model kits are available from all good toy and model retailers. On 01 January 1983, they performed the first scheduled service from Atlanta to Tampa.

The throttles could be closed in the flare and reverse idle set to open the reverser buckets. Wing span was reduced by roughly 17ft (5.2m), wing area by 30%, and overall length by 13ft (4.0m).

WebThe Trident Two-E was an effort to bring the Trident 1C closer to the Boeing 727-100 which was winning over most of Europe's airlines. Now powered by newer Spey 512s with 11,930lbf (53.1kN) thrust, it also replaced wing leading-edge droop flaps with slats, and extended the span with Kchemann-style tips. Designed for high speed, with a critical Mach number of 0.93,[43] the wing produced relatively limited lift at lower speeds.

By this time BEA had decided that, like everyone else, it also needed a jet with a bigger cabin and with more powerful engines. [44] The aerodynamics and wing was developed by a team led by Richard Clarkson, who would later use the Trident wing design as the basis for the wing of the Airbus A300; for the Trident he won the Mullard Award in 1969. Aircraft ordered to the beginning of 1981 according to the 1981 Edition of the Observer's Book of Aircraft. Below 280kn IAS, it was also possible to extend the main landing gear for use as an airbrake. This was helpful to reduce hydroplaning and give very short landing runs on wet or slippery runways while preserving wheel brake efficiency and keeping wheel brake temperatures low. It was built during 1962-1978; a total of 117 Tridents were assembled and put into service. I'm not qualified to comment on the Trident Vs 727 from an engineering standpoint, but the Trident did have many noteworthy features such as the ability to land in dense fog, which was very handy in UK winters.

Nevertheless, in December of that same year Lord Douglas of Kirtleside, BEA's chairman, stated that a number of jet-powered short haul aircraft might need to be introduced while retaining turboprop aircraft as the mainstay of the company's inventory for the foreseeable future. In 1957, de Havilland proposed its DH.121 trijet design to a British European Airways (BEA) request. WebThe resulting corporate moves and government interventions contributed to delays causing it to enter service two months after its major competitor, the Boeing 727, losing further potential sales as a result.
