Power-egg
A power-egg is a complete "unitized" Modular design, modular engine installation, consisting of engine and all ancillary equipment, which can be swapped between suitably designed equipment, with standardised quick-changing attachment points and connectors. In aircraft so designed, the power-egg is typically removed before Mean time between failures, mean time to failure is reached and a fresh one installed, the removed engine then being sent for maintenance. Spare power-eggs may be stored in sealed containers, to be opened when needed. The power-egg or ''Kraftei'' format was used in some German Second World War era aircraft, particularly for twin or multi-engined airframe designs. It existed in two differing formats – the initial ''Motoranlage'' format which used some specialized added components depending on what airframe it was meant for use on, and the ''Triebwerksanlage'' format, a more complete unitization format usually including exhaust and oil cooling systems.

Bristol Beaufighter
The Bristol Type 156 Beaufighter (often called the Beau) is a British multi-role aircraft developed during the Second World War by the Bristol Aeroplane Company. It was originally conceived as a heavy fighter variant of the Bristol Beaufort torpedo bomber. The Beaufighter proved to be an effective night fighter, which came into service with the Royal Air Force (RAF) during the Battle of Britain, its large size allowing it to carry heavy armament and early aircraft interception radar without major performance penalties. The Beaufighter was used in many roles; receiving the nicknames ''Rockbeau'' for its use as a rocket-armed ground attack aircraft and ''Torbeau'' as a torpedo bomber against Axis shipping, in which it replaced the Beaufort. In later operations, it served mainly as a maritime strike/ground attack aircraft, RAF Coastal Command having operated the largest number of Beaufighters amongst all other commands at one point. The Royal Australian Air Force (RAAF) al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
BMW 801
The BMW 801 was a powerful Nazi Germany, German Air-cooled engine, air-cooled 14-cylinder-radial engine, radial aircraft engine built by BMW and used in a number of German Luftwaffe aircraft of World War II. Production versions of the Radial engine#Multi-row radials, twin-row engine generated between 1,560 and 2,000 metric horsepower, PS (1,540–1,970 hp, or 1,150–1,470 Kilowatt, kW). It was the most produced radial engine of Germany in World War II with more than 61,000 built. The 801 was originally intended to replace existing radial types in German transport and utility aircraft. At the time, it was widely agreed among European designers that an inline engine (aviation), inline engine was a requirement for high performance designs due to its smaller frontal area and resulting lower drag. Kurt Tank successfully fitted a BMW 801 to a new fighter aircraft, fighter design he was working on, and as a result the 801 became best known as the power plant for the famous Focke ...

Bundesarchiv Bild 101I-332-3096-12, Russland, Entladen Eines Lastenseglers Go 242
The German Federal Archives or Bundesarchiv (BArch) (, lit. "Federal Archive") are the national archives of Germany. They were established at the current location in Koblenz in 1952. They are subordinated to the Federal Commissioner for Culture and the Media (Claudia Roth since 2021) under the German Chancellery, and before 1998, to the Federal Ministry of the Interior. On 6 December 2008, the Archives donated 100,000 photos to the public, by making them accessible via Wikimedia Commons. History The federal archive for institutions and authorities in Germany, the first precursor to the present-day Federal Archives, was established in Potsdam, Brandenburg in 1919, a later date than in other European countries. This national archive documented German government dating from the founding of the North German Confederation in 1867. It also included material from the older German Confederation and the Imperial Chamber Court. The oldest documents in this collection dated back to the y ...

Short Stirling
The Short Stirling was a British four-engined heavy bomber of the Second World War. It has the distinction of being the first four-engined bomber to be introduced into service with the Royal Air Force (RAF) during the war (the earlier Handley Page V/1500 being a WWI design that served during the 1920s). The Stirling was designed during the late 1930s by Short Brothers to conform with the requirements laid out in Air Ministry Specification B.12/36. Prior to this, the RAF had been primarily interested in developing increasingly capable twin-engined bombers, but had been persuaded to investigate a prospective four-engined bomber as a result of promising foreign developments in the field. Out of the submissions made to the specification, Supermarine proposed the Type 317, which was viewed as the favourite, whereas Short's submission, named the S.29, was selected as an alternative. When the preferred Type 317 had to be abandoned, the S.29, which later received the name Stirling, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vickers Wellington
The Vickers Wellington (nicknamed the Wimpy) is a British twin-engined, long-range medium bomber. It was designed during the mid-1930s at Brooklands in Weybridge, Surrey. Led by Vickers-Armstrongs' chief designer Rex Pierson, a key feature of the aircraft is its geodetic airframe fuselage structure, which was principally designed by Barnes Wallis. Development had been started in response to Air Ministry List Of Air Ministry Specifications, Specification B.9/32, issued in the middle of 1932, for a bomber for the Royal Air Force. This specification called for a twin-engined day bomber capable of delivering higher performance than any previous design. Other aircraft developed to the same specification include the Armstrong Whitworth Whitley and the Handley Page Hampden. During the development process, performance requirements such as for the tare weight changed substantially, and the engine used was not the one originally intended. Despite the original specification, the Wellingto ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Armstrong Whitworth Albemarle
The Armstrong Whitworth A.W.41 Albemarle was a twin-engine military transport aircraft, transport aircraft developed by the British aircraft manufacturer Armstrong Whitworth and primarily produced by Prefabs_in_the_United_Kingdom#Hawksley, A.W. Hawksley Ltd, a subsidiary of the Gloster Aircraft Company. It was one of many aircraft which entered service with the Royal Air Force (RAF) during the World War II, Second World War. The Albemarle had been originally designed as a medium bomber to fulfil List_of_Air_Ministry_specifications#1930–1939, Specification B.9/38 for an aircraft that could be built of wood and metal without using any light alloys; however, military planners decided to deemphasise the bomber role in favour of aerial reconnaissance and transport missions, leading to the aircraft being extensively redesigned mid-development. Performing its maiden flight on 20 March 1940, its entry to service was delayed by the redesign effort, thus the first RAF squadron to opera ...

Bristol Hercules
The Bristol Hercules is a 14-cylinder two-row radial aircraft engine designed by Sir Roy Fedden and produced by the Bristol Engine Company starting in 1939. It was the most numerous of their single sleeve valve ( Burt-McCollum, or Argyll, type) designs, powering many aircraft in the mid-World War II timeframe. The Hercules powered a number of aircraft types, including Bristol's own Beaufighter heavy fighter design, although it was more commonly used on bombers. The Hercules also saw use in civilian designs, culminating in the 735 and 737 engines for such as the Handley Page Hastings C1 and C3 and Bristol Freighter. The design was also licensed for production in France by SNECMA. Design and development Shortly after the end of World War I, the Shell company, Asiatic Petroleum, commissioned Harry Ricardo to investigate problems of fuel and engines. His book was published in 1923 as “The Internal Combustion Engine”. Ricardo postulated that the days of the poppet valve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bristol Aeroplane Company
The Bristol Aeroplane Company, originally the British and Colonial Aeroplane Company, was both one of the first and one of the most important British aviation companies, designing and manufacturing both airframes and aircraft engines. Notable aircraft produced by the company include the 'Boxkite', the Bristol Fighter, the Bulldog, the Blenheim, the Beaufighter, and the Britannia, and much of the preliminary work which led to Concorde was carried out by the company. In 1956 its major operations were split into Bristol Aircraft and Bristol Aero Engines. In 1959, Bristol Aircraft merged with several major British aircraft companies to form the British Aircraft Corporation (BAC) and Bristol Aero Engines merged with Armstrong Siddeley to form Bristol Siddeley. BAC went on to become a founding component of the nationalised British Aerospace, now BAE Systems. Bristol Siddeley was purchased by Rolls-Royce in 1966, who continued to develop and market Bristol-designed engines. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Air Ministry
The Air Ministry was a department of the Government of the United Kingdom with the responsibility of managing the affairs of the Royal Air Force and civil aviation that existed from 1918 to 1964. It was under the political authority of the Secretary of State for Air. Organisations before the Air Ministry The Air Committee On 13 April 1912, less than two weeks after the creation of the Royal Flying Corps (which initially consisted of both a naval and a military wing), an Air Committee was established to act as an intermediary between the Admiralty and the War Office in matters relating to aviation. The new Air Committee was composed of representatives of the two war ministries, and although it could make recommendations, it lacked executive authority. The recommendations of the Air Committee had to be ratified by the Admiralty Board and the Imperial General Staff and, in consequence, the Committee was not particularly effective.
