SR.N1
The Saunders-Roe SR.N1 (Saunders-Roe Nautical 1) was the first practical hovercraft. The concept has its origins in the work of British engineer and inventor Christopher Cockerell, who succeeded in convincing figures within the services and industry, including those within British manufacturer Saunders-Roe. Research was at one point supported by the Ministry of Defence; this was later provided by the National Research Development Corporation (NRDC), who had seen the potential posed by such a craft. In order to test the theories and overall concept, it was decided that a full-scale craft would be constructed, designated as the SR.N1. On 11 June 1959, it performed its first flight in front of the public. The SR.N1 participated in the test programme for four years prior to its retirement, by which point it had served its purpose in successfully validating the concept and further hovercraft had been developed. In less than four years following the SR.N1's maiden flight, multiple ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hovercraft
A hovercraft, also known as an air-cushion vehicle or ACV, is an amphibious Craft (vehicle), craft capable of travelling over land, water, mud, ice, and other surfaces. Hovercraft use blowers to produce a large volume of air below the hull, or air cushion, that is slightly above atmospheric pressure. The pressure difference between the higher pressure air below the hull and lower pressure ambient air above it produces lift, which causes the hull to float above the running surface. For stability reasons, the air is typically blown through slots or holes around the outside of a disk- or oval-shaped platform, giving most hovercraft a characteristic rounded-rectangle shape. The first practical design for hovercraft was derived from a British invention in the 1950s. They are now used throughout the world as specialised transports in disaster relief, coastguard, military and survey applications, as well as for sport or passenger service. Very large versions have been used to t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Christopher Cockerell
Sir Christopher Sydney Cockerell CBE RDI FRS (4 June 1910 – 1 June 1999) was an English engineer, best known as the inventor of the hovercraft. Early life and education Cockerell was born in Cambridge, where his father, Sir Sydney Cockerell, was curator of the Fitzwilliam Museum, having previously been the secretary of William Morris. His mother was the illustrator and designer Florence Kingsford Cockerell. Christopher attended the preparatory school of St Faith's. Christopher was educated at Gresham's School, Holt, Norfolk. He matriculated at Peterhouse, Cambridge to read mechanical engineering. He later returned to Cambridge to study radio and electronics. Early career He began his career working for W. H. Allen & Sons of Bedford. After returning to the University of Cambridge in 1934 to study radio and electronics, he went to work at the Radio Research Company. In 1935, he went to work at the Marconi Company, and soon afterwards he married Margaret Elinor Belsham (4 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saunders-Roe
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 ...

National Research Development Corporation
The National Research Development Corporation (NRDC) was a non-departmental government body established by the British Government to transfer technology from the public sector to the private sector. History The NRDC was established by Attlee's Labour government in 1948 to meet a perceived need at the time to exploit the many products that had been developed during World War II by the Defence Research Establishments. It was set up by the Board of Trade under the Development of Inventions Act 1948 and the first managing director was Lord Giffard. The NRDC was established in India in 1953 to help develop and promote technologies developed at various national R&D institutions. The first commercial size hovercraft, the SR.N1, was built under a contract let by the NRDC to Saunders-Roe in 1958. In 1981, the NRDC was combined with the National Enterprise Board ('NEB') to form the British Technology Group ('BTG'). Operations Typically the NRDC would patent the product for commerci ...

Subsidiary
A subsidiary, subsidiary company or daughter company is a company owned or controlled by another company, which is called the parent company or holding company. Two or more subsidiaries that either belong to the same parent company or having a same management being substantially controlled by same entity/group are called sister companies. The subsidiary can be a company (usually with limited liability) and may be a government- or state-owned enterprise. They are a common feature of modern business life, and most multinational corporations organize their operations in this way. Examples of holding companies are Berkshire Hathaway, Jefferies Financial Group, The Walt Disney Company, Warner Bros. Discovery, or Citigroup; as well as more focused companies such as IBM, Xerox, and Microsoft. These, and others, organize their businesses into national and functional subsidiaries, often with multiple levels of subsidiaries. Details Subsidiaries are separate, distinct legal entities f ...

British Army
The British Army is the principal land warfare force of the United Kingdom, a part of the British Armed Forces along with the Royal Navy and the Royal Air Force. , the British Army comprises 79,380 regular full-time personnel, 4,090 Gurkhas, and 28,330 volunteer reserve personnel. The modern British Army traces back to 1707, with antecedents in the English Army and Scots Army that were created during the Restoration in 1660. The term ''British Army'' was adopted in 1707 after the Acts of Union between England and Scotland. Members of the British Army swear allegiance to the monarch as their commander-in-chief, but the Bill of Rights of 1689 and Claim of Right Act 1689 require parliamentary consent for the Crown to maintain a peacetime standing army. Therefore, Parliament approves the army by passing an Armed Forces Act at least once every five years. The army is administered by the Ministry of Defence and commanded by the Chief of the General Staff. The Brit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wind Tunnel
Wind tunnels are large tubes with air blowing through them which are used to replicate the interaction between air and an object flying through the air or moving along the ground. Researchers use wind tunnels to learn more about how an aircraft will fly. NASA uses wind tunnels to test scale models of aircraft and spacecraft. Some wind tunnels are large enough to contain full-size versions of vehicles. The wind tunnel moves air around an object, making it seem as if the object is flying. Most of the time, large powerful fans suck air through the tube. The object being tested is held securely inside the tunnel so that it remains stationary. The object can be an aerodynamic test object such as a cylinder or an airfoil, an individual component, a small model of the vehicle, or a full-sized vehicle. The air moving around the stationary object shows what would happen if the object was moving through the air. The motion of the air can be studied in different ways; smoke or dye can be ...

Planform
In technical drawing and computer graphics, a multiview projection is a technique of illustration by which a standardized series of orthographic two-dimensional pictures are constructed to represent the form of a three-dimensional object. Up to six pictures of an object are produced (called ''primary views''), with each projection plane parallel to one of the coordinate axes of the object. The views are positioned relative to each other according to either of two schemes: ''first-angle'' or ''third-angle'' projection. In each, the appearances of views may be thought of as being ''projected'' onto planes that form a six-sided box around the object. Although six different sides can be drawn, ''usually'' three views of a drawing give enough information to make a three-dimensional object. These views are known as ''front view'', ''top view'' and ''end view''. Other names for these views include ''plan'', ''elevation'' and ''section''. When the plane or axis of the object depicted is n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radio-controlled Model
A radio-controlled model (or RC model) is a Physical model, model that is steering, steerable with the use of radio control. All types of model vehicles have had RC systems installed in them, including radio-controlled car, ground vehicles, radio-controlled boat, boats, radio-controlled airplane, planes, Radio-controlled helicopter, helicopters and even radio-controlled submarine, submarines and scale railway locomotives. History Radio control has been around since Nikola Tesla demonstrated a remote control boat in 1898. World War II saw increased development in radio control technology. The Luftwaffe used controllable winged bombs for targeting Allies of World War II, Allied ships. During the 1930s the Good brothers Bill and Walt pioneered vacuum tube based control units for R/C hobby use. Their "Guff" radio controlled plane is on display at the National Aerospace museum. Ed Lorenze published a design in Model Airplane News that was built by many hobbyists. Later, after WW2, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
