Anti-lock Brake Controller
An anti-lock braking system (ABS) is a automobile safety, safety anti-Skid (automobile), skid Brake, braking system used on aircraft and on land motor vehicle, vehicles, such as cars, motorcycles, trucks, and buses. ABS operates by preventing the wheels from locking up during braking, thereby maintaining traction (engineering), 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Brake Assist
Brake assist (BA or BAS) or emergency brake assist (EBA) is a term for an automobile braking technology that increases braking pressure in an emergency. The first application was developed jointly by Daimler-Benz and TRW/LucasVarity. Research conducted in 1992 at the Mercedes-Benz driving simulator in Berlin revealed that more than 90% of drivers fail to brake with enough force when faced with an emergency. By interpreting the speed and force with which the brake pedal is pushed, the system detects if the driver is trying to execute an emergency stop, and if the brake pedal is not fully applied, the system overrides and fully applies the brakes until the anti-lock braking system (ABS) takes over to stop the wheels locking up. This is a lower level of automation than advanced emergency braking which is a collision avoidance system, which may initiate braking on its own if the onboard computer detects an imminent collision. Overview Many drivers are not prepared for the rela ... [...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 ...

Vickers Valiant
The Vickers Valiant was a British high-altitude jet bomber designed to carry nuclear weapons, and in the 1950s and 1960s was part of the Royal Air Force's " V bomber" strategic deterrent force. It was developed by Vickers-Armstrongs in response to Specification B.35/46 issued by the Air Ministry for a nuclear-armed jet-powered bomber. The Valiant was the first of the V bombers to become operational, and was followed by the Handley Page Victor and the Avro Vulcan. The Valiant was the only V bomber to have dropped live nuclear weapons (for test purposes).Blackman and Wright 2015, p. 33. In 1956, Valiants operating from Malta flew conventional bombing missions over Egypt for Operation Musketeer during the Suez Crisis. From 1956 until early 1966 the main Valiant force was used in the nuclear deterrence role in the confrontation between NATO and the Warsaw Pact powers. Other squadrons undertook aerial refuelling, aerial reconnaissance and Electronic Warfare. In 1962, in respo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vickers Viscount
The Vickers Viscount is a British medium-range turboprop airliner first flown in 1948 by Vickers-Armstrongs. A design requirement from the Brabazon Committee, it entered service in 1953 and was the first turboprop-powered airliner. The Viscount was well received by the public for its cabin conditions, which included pressurisation, reductions in vibration and noise, and panoramic windows. It became one of the most successful and profitable of the first post-war transport aircraft; 445 Viscounts were built for a range of international customers, including in North America. Development Origins The Viscount was a response to the 1943 Brabazon Committee's proposed Type II design for a post-war small medium-range pressurised aircraft to fly less-travelled routes, carrying 24 passengers up to 1,750 mi (2,816 km) at 200 mph (320 km/h).Cacutt 1989, pp. 323–333.

Handley Page Victor
The Handley Page Victor is a British jet-powered strategic bomber developed and produced by Handley Page during the Cold War. It was the third and final '' V bomber'' to be operated by the Royal Air Force (RAF), the other two being the Avro Vulcan and the Vickers Valiant. Entering service in 1958, the Victor was initially developed as part of the United Kingdom's airborne nuclear deterrent, but it was retired from the nuclear mission in 1968, following the discovery of fatigue cracks which had been exacerbated by the RAF's adoption of a low-altitude flight profile to avoid interception, and due to the pending introduction of the Royal Navy's submarine-launched Polaris missiles in 1969. With the nuclear deterrent mission relinquished to the Royal Navy a large V-bomber fleet could not be justified. A number of Victors were modified for strategic reconnaissance, using a combination of radar, cameras, and other sensors. Prior to the introduction of Polaris, some had already ...

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 th ...

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] |
Robert Bosch
Robert Bosch (23 September 1861 – 12 March 1942) was a German industrialist, engineer and inventor, founder of Robert Bosch GmbH. Biography Bosch was born in Albeck, a village to the northeast of Ulm in southern Germany as the eleventh of twelve children. His parents came from a class of well-situated farmers from the region. His father, a freemason, was unusually highly educated for someone of his class, and placed special importance on a good education for his children. One of his brothers was Carl Friedrich Alexander Bosch (1843–1904), the father of Nobel laureate Carl Bosch. From 1869 to 1876, Bosch attended the Realschule (secondary-technical school) in Ulm, and then took an apprenticeship as a precision mechanic. After his school and practical education, Bosch spent a further seven years working at diverse companies in Germany, the United States (for Thomas Edison in New York), and the UK (for the German firm Siemens). On 15 November 1886, he opened his own "W ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Patent
A patent is a type of intellectual property that gives its owner the legal right to exclude others from making, using, or selling an invention for a limited period of time in exchange for publishing an sufficiency of disclosure, enabling disclosure of the invention."A patent is not the grant of a right to make or use or sell. It does not, directly or indirectly, imply any such right. It grants only the right to exclude others. The supposition that a right to make is created by the patent grant is obviously inconsistent with the established distinctions between generic and specific patents, and with the well-known fact that a very considerable portion of the patents granted are in a field covered by a former relatively generic or basic patent, are tributary to such earlier patent, and cannot be practiced unless by license thereunder." – ''Herman v. Youngstown Car Mfg. Co.'', 191 F. 579, 584–85, 112 CCA 185 (6th Cir. 1911) In most countries, patent rights fall under private law ...

Flywheel
A flywheel is a mechanical device which uses the conservation of angular momentum to store rotational energy; a form of kinetic energy proportional to the product of its moment of inertia and the square of its rotational speed. In particular, assuming the flywheel's moment of inertia is constant (i.e., a flywheel with fixed mass and second moment of area revolving about some fixed axis) then the stored (rotational) energy is directly associated with the square of its rotational speed. Since a flywheel serves to store mechanical energy for later use, it is natural to consider it as a kinetic energy analogue of an electrical inductor. Once suitably abstracted, this shared principle of energy storage is described in the generalized concept of an accumulator. As with other types of accumulators, a flywheel inherently smooths sufficiently small deviations in the power output of a system, thereby effectively playing the role of a low-pass filter with respect to the mechanical velocity ...

Gabriel Voisin
Gabriel Voisin (5 February 1880 – 25 December 1973) was a French aviation pioneer and the creator of Europe's first manned, engine-powered, heavier-than-air aircraft capable of a sustained (1 km), circular, controlled flight, which was made by Henry Farman on 13 January 1908 near Paris, France. During World War I the company founded by Voisin became a major producer of military aircraft, notably the Voisin III. Subsequently, he switched to the design and production of luxury automobiles under the name Avions Voisin. Early life Gabriel Voisin was born on 5 February 1880 in Belleville-sur-Saône, France, and his brother Charles Voisin, two years younger than him, was his main childhood companion. When his father abandoned the family his mother, Amélie, took her sons to Neuville-sur-Saône, where they settled near her father's factory. Their grandfather, Charles Forestier, took charge of the boys' education with military rigor. The boys also went for expeditions alon ...
