Maxaret
Dunlop's Maxaret was the first anti-lock braking system (ABS) to be widely used. Introduced in the early 1950s, Maxaret was rapidly taken up in the aviation world, after testing found a 30% reduction in stopping distances, and the elimination of tyre bursts or flat spots due to skids. Experimental fittings on cars and motorcycles demonstrated mixed performance, and ABS systems would not appear on mainstream, non sporting cars until the 1970s when electronic controls matured. Operation The Maxaret system had four main parts, all of which weighed only 4.7 pounds and fit within the small confines of a main landing gear wheel. The system was entirely mechanical, and worked by measuring the relative speed of two spinning disks. The first, the "drum", was surrounded by a rubber disk and arranged within the wheel's internal periphery, so that the rubber maintained strong mechanical contact with the wheel. The second, a flywheel, was attached to the drum with a one-way clutch. Normally, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anti-lock Braking System
An anti-lock braking system (ABS) is a safety anti-skid braking system used on aircraft and on land vehicles, such as cars, motorcycles, trucks, and buses. ABS operates by preventing the wheels from locking up during braking, thereby maintaining tractive contact with the road surface and allowing the driver to maintain more control over the vehicle. ABS is an automated system that uses the principles of threshold braking and cadence braking, techniques which were once practiced by skillful drivers before ABS was widespread. ABS operates at a much faster rate and more effectively than most drivers could manage. Although ABS generally offers improved vehicle control and decreases stopping distances on dry and some slippery surfaces, on loose gravel or snow-covered surfaces ABS may significantly increase braking distance, while still improving steering control. Since ABS was introduced in production vehicles, such systems have become increasingly sophisticated and effective. Mode ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
English Electric Lightning
The English Electric Lightning is a British fighter aircraft that served as an interceptor during the 1960s, the 1970s and into the late 1980s. It was capable of a top speed of above Mach 2. The Lightning was designed, developed, and manufactured by English Electric, which was later merged into the newly-formed British Aircraft Corporation. Later the type was marketed as the BAC Lightning. It was operated by the Royal Air Force (RAF), the Kuwait Air Force (KAF), and the Royal Saudi Air Force (RSAF). A unique feature of the Lightning's design is the vertical, staggered configuration of its two Rolls-Royce Avon turbojet engines within the fuselage. The Lightning was designed and developed as an interceptor to defend the V bomber airfields from attack by anticipated future nuclear-armed supersonic Soviet bombers such as what emerged as the Tupolev Tu-22, but it was subsequently also required to intercept other bomber aircraft such as the Tupolev Tu-16 and the Tupolev Tu-9 ...

Royal Enfield Super Meteor
The Super Meteor was a British motorcycle made by Royal Enfield for export to the US between 1952 and 1962, when the Super Meteor was replaced by the 736 cc Royal Enfield Interceptor. Development In 1953, the US export market led Royal Enfield to develop a 692 cc, overhead valve twin capable of , which was launched as the Meteor. The engine was basically a modified 500 twin crankcase with 350 single (Bullet) pistons, valves and identical 90mm stroke length. In 1954, the Super Meteor was updated and fitted with a new cast alloy headlight nacelle (casquette) housing the speedometer, ammeter and light switch. During 1955, the dynamo and coil ignition was replaced with a Lucas magdyno. This model was replaced by the Super Meteor in 1956 that sported a brand new frame. Based on the Royal Enfield Meteor Minor 496 cc overhead valve engine, the new model had a strengthened crank and improved clutch. The frame was also strengthened to handle the increased torque. The gearbox ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hawker Siddeley Trident
The Hawker Siddeley HS-121 Trident (originally the de Havilland DH.121 and briefly the Airco DH.121) is a British airliner produced by Hawker Siddeley. In 1957, de Havilland proposed its DH.121 trijet design to a British European Airways (BEA) request. By 1960, de Havilland had been acquired by Hawker Siddeley. The Trident's maiden flight happened on 9 January 1962, and it was introduced on 1 April 1964, two months after its main competitor, the Boeing 727. By the end of the programme in 1978, 117 Tridents had been produced. The Trident was withdrawn from service in 1995. The jetliner is powered by three rear-mounted Rolls-Royce Spey low-bypass turbofans, it has a low swept wing and a T-tail. Advanced avionics allowed it to be the first airliner to make a blind landing in revenue service in 1965. The initial Trident 1/2 could seat 101-115 passengers over up to . The Trident 3 was stretched by to seat 180 over , and had an additional RB.162 booster engine in the tail. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dunlop Rubber
Dunlop Ltd. (formerly Dunlop Rubber) was a British multinational company involved in the manufacture of various natural rubber goods. Its business was founded in 1889 by Harvey du Cros and he involved John Boyd Dunlop who had re-invented and developed the first pneumatic tyre. It was one of the first multinationals, and under du Cros and, after him, under Eric Geddes, grew to be one of the largest British industrial companies. J B Dunlop had dropped any ties to it well before his name was used for any part of the business. The business and manufactory was founded in Upper Stephens Street in Dublin. A plaque marks the site, which is now part of the head office of the Irish multinational departments store brand, Dunnes Stores. Dunlop Rubber failed to adapt to evolving market conditions in the 1970s, despite having recognised by the mid-1960s the potential drop in demand as the more durable Radial tire, radial tyres swept through the market. After taking on excessive debt Dunlop w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Avro Vulcan
The Avro Vulcan (later Hawker Siddeley Vulcan from July 1963) is a jet-powered, tailless, delta-wing, high-altitude, strategic bomber, which was operated by the Royal Air Force (RAF) from 1956 until 1984. Aircraft manufacturer A.V. Roe and Company ( Avro) designed the Vulcan in response to Specification B.35/46. Of the three V bombers produced, the Vulcan was considered the most technically advanced, hence the riskiest option. Several reduced-scale aircraft, designated Avro 707s, were produced to test and refine the delta-wing design principles. The Vulcan B.1 was first delivered to the RAF in 1956; deliveries of the improved Vulcan B.2 started in 1960. The B.2 featured more powerful engines, a larger wing, an improved electrical system, and electronic countermeasures, and many were modified to accept the Blue Steel missile. As a part of the V-force, the Vulcan was the backbone of the United Kingdom's airborne nuclear deterrent during much of the Cold War. Although the ...

Jensen FF
The Jensen FF is a four-wheel drive grand tourer produced by British car manufacturer Jensen Motors between 1966 and 1971. It was the first non all-terrain production car equipped with four-wheel drive and an anti-lock braking system. The powertrain was sourced from Chrysler, installing the second generation V8 engine and 3-speed '' TorqueFlite A727'' automatic transmission. The use of four-wheel drive in a passenger car preceded the successful AMC Eagle by thirteen years, the Audi Quattro by fourteen years, and the Subaru Leone by five years. The Dunlop Maxaret mechanical anti-lock braking system had previously been used only on aircraft, lorries, and racing cars. An experimental version was first fitted to the earlier Jensen C-V8, but this did not go into production. The letters FF stand for ''Ferguson Formula'', after Ferguson Research Ltd., who invented the car's four-wheel drive system. The FF is related to the similar-looking, rear-wheel drive Jensen Interceptor, but ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

British Aerospace 125
The British Aerospace 125 is a twinjet mid-size business jet. Originally developed by de Havilland and initially designated as the DH.125 Jet Dragon, it entered production as the Hawker Siddeley HS.125, which was the designation used until 1977. Later on, more recent variants of the type were marketed as the Hawker 800. More than 60% of the total sales of the aircraft were to North American customers.Jerram, Mike"The last de Havilland."''Flying Magazine'', 120 (9). p. 43. It was also used by the Royal Air Force as a navigation trainer, as the Hawker Siddeley Dominie T1, and was operated by the United States Air Force as a calibration aircraft, under the designation C-29. Development Origins In 1961, de Havilland began work upon a small business jet, then known as the ''DH.125 Jet Dragon'', which was intended to replace the piston engined de Havilland Dove, a successful business aircraft and light transport. Prior to the start of the project, de Havilland had determined th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hawker Siddeley HS 748
The Hawker Siddeley HS 748 is a medium-sized turboprop airliner originally designed and initially produced by the British aircraft manufacturer Avro. It was the last aircraft to be developed by Avro prior to its absorption by Hawker Siddeley. The HS 748 was developed during the late 1950s as a move to re-orientate the company towards the civil and export markets. Powered by the popular Rolls-Royce Dart turboprop engine, it was specifically designed as a modern feederliner to act as a replacement for the aging Douglas DC-3s then in widespread service. Originally intended to seat a smaller number of passengers, market research indicated that a seating capacity of around 40 passengers would be optimal for the type. As a means to differentiate the new airliner from competitors, it was designed to possess a high level of performance, including its short takeoff and landing (STOL) capabilities and overall ruggedness. First flying on 24 June 1960, the series 1 HS 748 entered revenue s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
BAC One-Eleven
The BAC One-Eleven (or BAC-111/BAC 1-11) was an early jet airliner produced by the British Aircraft Corporation (BAC). Originally conceived by Hunting Aircraft as a 30-seat jet, before its merger into BAC in 1960, it was launched as an 80-seat airliner with a British United Airways order on 9 May 1961. The prototype conducted its maiden flight on 20 August 1963, and it was first delivered to its launch customer on 22 January 1965. The 119-seat, stretched 500 series was introduced in 1967. Total production amounted to 244 until 1982 in the United Kingdom and between 1982 and 1989 in Romania where nine Rombac One-Eleven were licence-built by Romaero. The short haul, narrowbody aircraft was powered by aft-mounted Rolls-Royce Spey low-bypass turbofans, a configuration similar to the earlier Sud Aviation Caravelle and later Douglas DC-9. It also competed with early Boeing 737 variants and was used by several US carriers, as well as multiple British, overseas and European airline ...

British Aerospace ATP
The British Aerospace ATP (Advanced Turbo-Prop) is an airliner designed and produced by British Aerospace. It was an evolution of the Hawker Siddeley HS 748, a fairly successful feederliner of the 1960s. The ATP was developed during the 1980s, events such as such as the 1979 oil crisis and increasing public concern regarding aircraft noise led to business planners at British Aerospace to believe that there was a market for a short-range, low-noise, fuel-efficient turboprop aircraft. First flown on 6 August 1986, by the time it became commercially available, the market segment it fell within was already hotly contested by multiple other airliners, such as the de Havilland Canada Dash 8, ATR 42, and ATR 72. Amid this intense competition, sales of the ATP were limited, leading British Aerospace to terminate production after only eight years, during which a total of 65 aircraft were completed. Design and development Background The origins of the ATP can be traced back to, in par ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
