de Havilland DH 106 Comet
The de Havilland DH 106 Comet is a British narrow-bodied four-engined and the first commercial jet airliner. The maiden flight took place on July 27, 1949, and entered service on May 2, 1952, with BOAC. With a speed and climb rate about one and a half times greater than piston-engine airliners, coupled with a pressurised cabin, large windows, gave the aircraft a faster relatively quiet, vibration free and comfortable flight. Development into four major variants, the Comet 1, -2, – 3 and -4. The Comet 4 with increased range and reliability enabled jet-powered transatlantic routes, BOAC flew the inaugural service on October 4, 1958. By the end of the month the B707 had entered service and by 1960 the DC-8, more cost-effective, bigger, faster and longer range. BOAC withdrew its last Comet 4s from service in November 1965 and the final operator Dan-Air in 1981.
Early models seated 36 passengers four abreast, the last, the -4C, up to 119 passengers in a single class. The fuselage housed a luggage storage areas as there was no cargo hold. The engines, mounted in pairs and embedded in the wings close to the fuselage gave less drag than podded engines. Minimised asymmetric thrust, lessened the risk of ingestion of foreign objects. But increased wing structural weight, complexity and required armour sheathing to prevent further damage from significant engine failures.
The high pressurisation and fast speed of the aircraft made the use of new materials and innovative technologies necessary. The aeroplane underwent more comprehensive verification during design, development and flight trials than any contemporary airliner. During early service, a series of accidents revealed serious design flaws with the aircraft. Firstly, Several aircraft failed to become airborne, running off the end of the airstrip. Next, a major structural failure occurred in a severe thundersquall. Blamed on the weather and the pilot overstressing the airframe. During 1954, two Comets suffered catastrophic structural failure in flight with no apparent cause. Testing revealed metal fatigue, caused by in-flight pressurisation and dynamic stresses, not understood at the time. The redesigned Comet 4, introduced in 1958, addressed these problems and remained in service for over 30 years.
The RCAF became the first air force to operate jet transports with the delivery of the first of two Comet 1As on May 29, 1953. The RAF used the Comet 4 (designated as the C.4) in a variety of roles including VIP, medical and passenger transport, assigned to No. 216 Squadron. A maritime patrol variant, the Hawker Siddeley Nimrod served with the RAF from 1967 until 2011.
