History In 1945, the British Air Forces of Occupation (BAFO) in Germany began using captured German gliders to provide recreational flying for RAF personnel. This resulted in a demand for similar facilities in the United King ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RAF Bicester
Bicester Aerodrome, formerly RAF Bicester, is an airfield on the outskirts of the England, English town of Bicester in Oxfordshire. Dating back to 1916, this military airfield is notable as the location of the first flight of the prototype Handley Page Halifax in 1939 and was later the home of No. 71 Maintenance Unit, RAF (Royal Air Force); the RAF finally left in 2004. The airfield consists of of well-drained short-mown grass, with two nominal runways (not marked) of 06/24 () and 16/34 () long. The airfield surface is bumpy in places, due to collapsing drainage, field drains, requiring care on the part of pilots operating aircraft in those areas. History In 1911, flying first took place on the site, when Lt H.R.P Reynolds landed a Bristol Boxkite biplane on the field. Organised flying began in 1916 when a Training Depot was established. In January 1917, the Royal Flying Corps (RFC) moved into the site, then , with the arrival of No. 118 Squadron RAF, 118 night bomber squadron. ...

Windrushers Gliding Club
Windrushers Gliding Club (also known as Bicester Gliding Club or simply "Bicester" within gliding circles) was a gliding club flying from Bicester Airfield in Oxfordshire until late June 2020. At its heyday, the club was one of the biggest gliding clubs in the UK, hosting various competitions throughout the year and maintaining the physical presence of the British Gliding Association's shop as well as numerous BGA staff members. The club operated seven days a week, with paid staff running various elements of the club's operations. The club also hosted Oxford University Gliding Club at their site until Windrusher's closure, where OUGC then relocated to Oxford Gliding Club. During their tenancy, the gliding Varsity match between Oxford University Gliding Club and Cambridge University Gliding Club was held at Bicester Airfield every other year, the other years it was held at Gransden Lodge Airfield. Due to the COVID-19 pandemic these competitions were not held but in the early s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RAF Keevil
Royal Air Force Station Keevil or more simply RAF Keevil is a former Royal Air Force station located between the villages of Keevil and Steeple Ashton, about east of the town of Trowbridge, in Wiltshire, England. The airfield was built on a site previously ear-marked for the purpose in the mid-1930s. With three long concrete runways, the airfield was used by the Royal Air Force and the United States Army Air Forces Eighth and Ninth Air Forces. Although no longer a RAF station and now known as Keevil Airfield, it is maintained for military use and used for training purposes, predominantly by aircraft from RAF Brize Norton and Joint Helicopter Command. History Spitfire assembly After air raids in 1940 on the Spitfire production plants near Southampton, the Trowbridge area was one of several chosen for dispersal of production. At first parts were made, and later complete aircraft after completion of a purpose-built factory at Bradley Road, Trowbridge. Fuselages and wings ...

Slingsby Prefect
The Slingsby T.30 Prefect is a 1948 British modernisation of the 1932 single-seat Grunau Baby glider. About 53 were built for civil and military training purposes. Development In 1948, Slingsby Sailplanes developed the 1932 Grunau Baby, which it had built under licence before World War II, into the Slingsby T.30 Prefect, an intermediate-level semi-aerobatic glider suitable for civil or military use. In the same year, Elliotts of Newbury introduced its version of the Grunau Baby, the Baby Eon; all three types were visually very similar, but differed slightly in dimensions, undercarriage, airbrakes, equipment and performance. The Prefect, like the Grunau Baby, was a single-seat fabric-covered wooden glider. It had high-mounted semi-cantilever straight-tapered wings, with a single wing bracing strut on each side, from the base of the fuselage to the wing spar. The span was 150 mm (6 in) greater than that of the Grunau Baby, and the tips enclosed the outer ends of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gliding
Gliding is a recreational activity and competitive air sport in which pilots fly unpowered aircraft known as gliders or sailplanes using naturally occurring currents of rising air in the atmosphere to remain airborne. The word ''soaring'' is also used for the sport. Gliding as a sport began in the 1920s. Initially the objective was to increase the duration of flights but soon pilots attempted cross-country flights away from the place of launch. Improvements in aerodynamics and in the understanding of weather phenomena have allowed greater distances at higher average speeds. Long distances are now flown using any of the main sources of rising air: ridge lift, thermals and lee waves. When conditions are favourable, experienced pilots can now fly hundreds of kilometres before returning to their home airfields; occasionally flights of more than are achieved. Some competitive pilots fly in races around pre-defined courses. These gliding competitions test pilots' abilities t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saunders Roe Princess
The Saunders-Roe SR.45 Princess was a British flying boat aircraft developed and built by Saunders-Roe at their Cowes facility on the Isle of Wight. It has the distinction of being the largest all-metal flying boat to have ever been constructed. The Princess had been developed to serve as a larger and more luxurious successor to the pre-war commercial flying boats, such as the Short Empire. It was intended to serve the transatlantic route, carrying up to 100 passengers between Southampton, United Kingdom and New York City, United States in spacious and comfortable conditions. To achieve this, it was decided early on to make use of newly developed turboprop technology, opting for the Bristol Proteus engine still in development to power the aircraft. The project suffered delays due to difficulties encountered in the development of the Proteus engine. On 22 August 1952, the first prototype Princess, ''G-ALUN'', conducted its maiden flight. Between 1952 and 1954, the first prototype ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saunders-Roe SR
Saunders-Roe Limited, also known as Saro, was a British aero- and marine-engineering company based at Columbine Works, East Cowes, Isle of Wight. History The name was adopted in 1929 after Alliott Verdon Roe (see Avro) and John Lord took a controlling interest in the aircraft and boat-builders S. E. Saunders. Prior to this (excepting for the Sopwith/Saunders Bat Boat) the products were Saunders, the A4 Medina for example dating from 1926. Sam Saunders the founder developed the Consuta material used in marine and aviation craft. The Saunders-Roe interest in aviation didn’t prevent the firm from continuing with the boatbuilding activities associated with S. E. Saunders Ltd Saunders Roe concentrated on producing flying-boats, but none were produced in very large quantities – the longest run being 31 Londons. They also produced hulls for the Blackburn Bluebird. During the Second World War Saro manufactured Supermarine Walrus and Supermarine Sea Otters. Their works ...

Aviation Engineering
Aviation engineering is a branch of engineering which deals with airspace development, airport design, aircraft navigation technologies, and aerodrome planning. It also involves the formulation of public policy, regulations, aviation laws pertaining to airspace, airlines, airports, aerodromes and the conduct of air services agreements through treaty. This branch of engineering is distinct from aerospace engineering which deals with the development of aircraft and spacecraft. Airspace development The global airspace is divided into territorial airspace which then belongs to a country. Generally, airspace has to be engineered to benefit both military and civil users. Planning and designing airspace is important so as not to affect military operations and in order to designate air routes for commercial airlines to navigate freely without intervention by military authorities. For instance, not all of China can be used for commercial aeronautical navigation. Certain airspaces are desig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Light Aircraft
A light aircraft is an aircraft that has a maximum gross takeoff weight of or less.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', page 308. Aviation Supplies & Academics, 1997. Light aircraft are used as utility aircraft commercially for passenger and freight transport, sightseeing, photography, and other roles, as well as personal use. Examples of aircraft that are at the maximum gross takeoff weight for this category include the de Havilland Canada DHC-6 Twin Otter and Beechcraft B200 Super King Air. Uses Uses include aerial surveying, such as monitoring pipelines, light cargo operations, such as "feeding" cargo hubs, and passenger operations. Light aircraft are used for marketing purposes, such as banner towing and skywriting, and flight instruction. The majority of personal aircraft are light aircraft, the most popular in history being the Cessna 172, and most popular in modern history being the Cirrus SR22 and Robinson R44.

Crown Gear
A crown gear (also known as a face gear or a contrate gear) is a gear which has teeth that project at right angles to the face of the wheel. In particular, a crown gear is a type of bevel gear where the pitch cone angle is 90 degrees. A pitch cone of any other angle is simply called a bevel gear. Crown gears normally mesh with other bevel gears, or sometimes spur gears, a typical use being a crown gear and pinion system which allows a rotary motion to be shifted 90 degrees. See also * Crown circle * Bevel gear Bevel gears are gears where the axes of the two shafts intersect and the tooth-bearing faces of the gears themselves are conically shaped. Bevel gears are most often mounted on shafts that are 90 degrees apart, but can be designed to work at ot ... ** Spiral bevel gear References Gears {{Mech-engineering-stub ...
