In June 1966, a complete Olympus 593 engine and variable geometry exhaust assembly was first run at Melun-Villaroche. At Bristol, flight tests began using a RAF Avro Vulcan bomber with the engine and its nacelle attached below the bomb-bay. Due to the Vulcan's aerodynamic limitations, the tests were limited to a speed of Mach 0.98 (1,200 km/h ...
After cost overruns and delays the programme eventually cost between £1.5 and £2.1 billion in 1976, [67] (£11.4 billion – 16 billion in 2023). [66] This cost was the main reason the production run was much smaller than expected. [68]
Concorde, the world’s fastest commercial aircraft, has been making a rare journey – floating down New York’s Hudson River.
Concorde was originally designed for cruising speeds up to Mach 2.2, [55] but its regular service speed was limited to Mach 2.02 to extend airframe life. [56] One of Tupolev's web site pages states that "TU-144 and TU-160 aircraft operation has demonstrated expediency of limitation of cruise supersonic speed of M=2.0 to provide structure ...
Sir, Miss Pamela Hansford and Sir Alec Guinness (July 5 and 10), and many other readers of 'The Times' may be glad to know of the existence of the Anti-Concord Project, which has been founded by a group of some hundreds of people including scientists, artists, business men, civil servants, farmers, housewives, professors, M.P.s etc. who are ...
Boeing also faced insurmountable weight problems due to the swing-wing mechanism, a titanium pivot section having been fabricated with a weight of 4,600 pounds (2,100 kg) and measuring 11 feet (3.4 m) long and 2.5 feet (76 cm) thick, [16] and the design could not achieve sufficient range. Flexing of the fuselage (it would have been the longest ...
In 1955 Avro estimated the performance of the Arrow Mk 2 (with Iroquois) as follows, from the January 1955 British evaluation titled Evaluation of the CF.105 as an All Weather Fighter for the RAF: "Max speed Mach 1.9 at 50,000 ft, Combat speed of Mach 1.5 at 50.000 feet and 1.84 G without bleeding energy, time to 50,000 ft of 4.1 minutes, 500 ...
[3]: 17, 107 [5] At 16:42, the Concorde ran over this piece of debris during its take-off run while the aircraft was at a speed of 185 mph (300 km/h), cutting the right-front tyre (tyre No 2) of its left main wheel bogie and sending a large chunk of tyre debris (4.5 kilograms or 9.9 pounds) into the underside of the left wing at an estimated ...
