Royal Air Force Gliding And Soaring Association
The Royal Air Force Gliding & Soaring Association is a British organisation which provides recreational flying in gliders to RAF personnel. Purpose The Royal Air Force Gliding & Soaring Association (RAFGSA) is a voluntary organisation which exists to provide recreational flying to all RAF servicemen and women, in particular those normally employed in ground duties. The RAFGSA Centre is at RAF Halton, employing a full-time staff to provide central organisational, training and workshop facilities. The Joint Services Gliding Centre (JSGC), located at the RAFGSA Chilterns Centre, RAF Halton, is part of the Joint Service Adventurous Training (JSAT) Air Sports organisation and provides training courses for military personnel. 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 Kingdom, and the Royal Air Force Gliding ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RAF Detling
Royal Air Force Detling or more simply RAF Detling is a former Royal Air Force station situated above sea level, located near Detling, a village about miles north-east of Maidstone, Kent. It was a station of the Royal Naval Air Service (RNAS) in the First World War and the Royal Air Force (RAF) in the Second World War. Although not a fighter base, the airfield suffered several raids by the Luftwaffe, especially during the period of the Battle of Britain. History ''RNAS Detling'' airfield was north east of Maidstone, and was used jointly by the Navy and Air Force between 1916 and 1919. The Fleet Air Arm aircraft also shared some facilities during the second World War. The site was developed in April 1915, covering some , although it was April 1917 before the first occupants, No. 50 Squadron arrived from Dover. The airfield closed in December 1919 to military flying, and after the war it was used by the Short factory at Rochester to test aircraft, and civilian gliding also sta ...

Civil Aviation Authority
A civil aviation authority (CAA) is a national or supranational statutory authority that oversees the regulation of civil aviation, including the maintenance of an aircraft register. Role Due to the inherent dangers in the use of flight vehicles, national aviation authorities typically regulate the following critical aspects of aircraft airworthiness and their operation: * design of aircraft, engines, airborne equipment and ground-based equipment affecting flight safety * conditions of manufacture and testing of aircraft and equipment * maintenance of aircraft and equipment * operation of aircraft and equipment * licensing of pilots, air traffic controllers, flight dispatchers and maintenance engineers * licensing of airports and navigational aids * standards for air traffic control. Depending on the legal system of the jurisdiction, a CAA will derive its powers from an act of parliament (such as the Civil or Federal Aviation Act), and is then empowered to make regulations withi ...

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 w ...

Coffman Engine Starter
The Coffman engine starter (also known as a "shotgun starter") was a starting system used on many piston engines in aircraft and armored vehicles of the 1930s and 1940s. It used a cordite cartridge to move a piston, which cranked the engine. The Coffman system was one of the most common brands; another was the Breeze cartridge system, which was produced under Coffman patents. Most American military aircraft and tanks which used radial engines were equipped with this system. Some versions of the Rolls-Royce Merlin engine used in the British Supermarine Spitfire used the Coffman system as a starter. The Hawker Typhoon and Hawker Tempest also used the Coffman system to start their Napier Sabre engines. Cartridge starters used on a number of jet engines, including such engines as the Rolls-Royce Avon, which were used in the English Electric Canberra and Hawker Hunter aircraft, used a high gas volume cartridge driving a turbine instead of a piston. Some Snowcat and similar vehicles use ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ** Spiral bevel gear A spiral bevel gear is a bevel gear with helical teeth. The main application of this is in a vehicle differential, where the direction of drive from the drive shaft must be turned 90 degrees to drive the wheels. The helical design produces less ...

Aerotow
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 to mak ...

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.

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 design ... [...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 at ...
