Welbike
The Welbike was a British single-seat folding motorcycle produced during World War II at the direction of Station IX — the "Inter Services Research Bureau" — based at Welwyn, UK, for use by Special Operations Executive (SOE). It has the distinction of being the smallest motorcycle ever used by the British Armed Forces. Between 1942 and 1943, 3,641 units (plus a prototype and some pilot models) were built and, although not much used by the SOE, some were issued to the British 1st and 6th Airborne Divisions and some were used at Arnhem during Operation Market Garden. The Italians, Germans and Americans also developed small motorcycles for their airborne forces during World War II. Development The original prototype was designed by SOE motor cycle enthusiast Harry Lester, from an idea developed by Lt. Colonel John Dolphin, the Commanding Officer of Station IX, the secret Inter-Services Military Research Establishment based in a mansion called The Frythe (latterly owned by ...

Excelsior Motor Company
Excelsior, based in Coventry, was a British bicycle, motorcycle and car maker. They were Britain’s first motorcycle manufacturer, starting production of their own ‘motor-bicycle’ in 1896. Initially they had premises at Lower Ford Street, Coventry, and 287-295 Stoney Stanton Road, Hillfields, Coventry, Warwickshire before moving to Kings Road, Tyseley, Birmingham in 1921. Originally a bicycle company making penny-farthings in 1874 under their original name: Bayliss, Thomas and Co, they later sold bicycles under the names of Excelsior and Eureka and changed the company name to Excelsior Motor Co. in 1910. In the early years of motor-bicycle manufacture they used Minerva, De Dion, MMC and possibly a Condor 850 cc single but went on to produce a wide range of machines with engines from most major manufacturers. In 1914, they offered a JAP-powered twin. A deal to supply the Russian Imperial government with motorcycles ended with the Revolution and Excelsior wound up with an ...

Push Start
Push starting, also known as bump starting, roll starting, clutch starting, popping the clutch or crash starting, is a method of starting a motor vehicle with an internal combustion engine and with a manual transmission and with a mechanical fuel pump and a mechanically driven generator or alternator. By pushing or letting the vehicle roll downhill then engaging the clutch at the appropriate speed the engine will turn over and start. The technique is most commonly employed when other starting methods (automobile self starter, kick start, jump start etc.) are unavailable. The most common way to push start a vehicle is to put the manual transmission in second gear, switching the ignition to on/run, depressing the clutch, and pushing the vehicle until it is at a speed of or more, then quickly engaging the clutch to make the engine rotate and start while keeping the gas pedal partially depressed, then quickly disengaging the clutch so it does not stall. Types Push starting is mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Welrod
The Welrod is a British bolt action, Magazine (firearms), magazine fed, suppressor, suppressed pistol devised during the Second World War by Major Hugh Reeves at the Inter-Services Research Bureau (later Station IX). Station IX, being based near Welwyn Garden City, gave the Welrod its unusual name, being derived from "Wel" from "Welwyn Garden City" (a prefix used by covert equipment designed by Station IX) and "rod", gangland slang for gun, as a way to obscure its purpose. Designed for use by Irregular military, irregular forces and resistance groups, the Welrod is an extremely quiet gun thanks to its integrated suppressor. Approximately 2,800 were made in wartime and perhaps 14,000 in total when post-war examples are included. Development The name ''Welrod'' comes from the custom of naming all clandestine equipment devised at Station IX in Welwyn Garden City starting with ''Wel'', e.g., ''Welbike'', ''Welman''. A document produced towards the end of the war ensured that the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Villiers Engineering
Villiers Engineering was a manufacturer of motorcycles and cycle parts, and an engineering company based in Villiers Street, Wolverhampton, England. Early history In the 1890s John Marston's Sunbeam had become extremely successful by relying on high quality of production and finish. But Marston was dissatisfied with the pedals on his machines, which he bought in. In 1890 he dispatched his son Charles to the US on a selling trip, but included in his instructions that Charles must discuss pedal engineering with Pratt and Whitney in Hartford, Connecticut and come back with a high-class pedal and the machinery for making it. Charles said that the Villiers Engineering Co. was "the ultimate fruit" of his trip to the US, being impressed by the production system and the labour saving devices. He pointed out that "it was not possible to develop these at Sunbeamland, which had long been working on another plan, but it was possible to start them in a new factory". As a result of the to ...

Special Operations Executive
The Special Operations Executive (SOE) was a secret British World War II organisation. It was officially formed on 22 July 1940 under Minister of Economic Warfare Hugh Dalton, from the amalgamation of three existing secret organisations. Its purpose was to conduct espionage, sabotage and reconnaissance in occupied Europe (and later, also in occupied Southeast Asia) against the Axis powers, and to aid local resistance movements. Few people were aware of SOE's existence. Those who were part of it or liaised with it were sometimes referred to as the "Baker Street Irregulars", after the location of its London headquarters. It was also known as "Churchill's Secret Army" or the "Ministry of Ungentlemanly Warfare". Its various branches, and sometimes the organisation as a whole, were concealed for security purposes behind names such as the "Joint Technical Board" or the "Inter-Service Research Bureau", or fictitious branches of the Air Ministry, Admiralty or War Office. SOE operated ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1st Airborne Division (United Kingdom)
The 1st Airborne Division was an airborne infantry division of the British Army during the Second World War. The division was formed in late 1941 during the Second World War, after the British Prime Minister, Winston Churchill, demanded an airborne force, and was initially under command of Major-General Frederick A. M. Browning. The division was one of two airborne divisions raised by the British Army during the war, with the other being the 6th Airborne Division, created in May 1943, using former units of the 1st Airborne Division. The division's first two missions—Operation Biting, a parachute landing in France, and Operation Freshman, a glider mission in Norway—were both raids. Part of the division was sent to North Africa at the end of 1942, where it fought in the Tunisian Campaign, and when the Allies invaded Sicily in July 1943, the division undertook two brigade sized landings. The first, Operation Ladbroke, carried out by glider infantry of the 1st Airlanding Br ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Air-cooled Engine
Air-cooled engines rely on the circulation of air directly over heat dissipation fins or hot areas of the engine to cool them in order to keep the engine within operating temperatures. In all combustion engines, a great percentage of the heat generated (around 44%) escapes through the exhaust, not through the metal fins of an air-cooled engine (12%). About 8% of the heat energy is transferred to the oil, which although primarily meant for lubrication, also plays a role in heat dissipation via a cooler. ''Air-cooled engines'' are used generally in applications which would not suit liquid cooling, as such modern air-cooled engines are used in motorcycles, general aviation aircraft, lawn mowers, generators, outboard motors, pump sets, saw benches and auxiliary power units. Introduction Most modern internal combustion engines are cooled by a closed circuit carrying liquid coolant through channels in the engine block and cylinder head, where the coolant absorbs heat, to a heat ...

Royal Air Force
The Royal Air Force (RAF) is the United Kingdom's air and space force. It was formed towards the end of the First World War on 1 April 1918, becoming the first independent air force in the world, by regrouping the Royal Flying Corps (RFC) and the Royal Naval Air Service (RNAS). Following the Allied victory over the Central Powers in 1918, the RAF emerged as the largest air force in the world at the time. Since its formation, the RAF has taken a significant role in British military history. In particular, it played a large part in the Second World War where it fought its most famous campaign, the Battle of Britain. The RAF's mission is to support the objectives of the British Ministry of Defence (MOD), which are to "provide the capabilities needed to ensure the security and defence of the United Kingdom and overseas territories, including against terrorism; to support the Government's foreign policy objectives particularly in promoting international peace and security".
