CAC CA-15
The CAC CA-15, also known unofficially as the CAC Kangaroo, was an Australian propeller-driven fighter aircraft designed by the Commonwealth Aircraft Corporation (CAC) during World War II. Due to protracted development, the project was not completed until after the war, and was cancelled after flight testing, when the advent of jet aircraft was imminent. Design and development During 1943, following its success in rapidly designing and mass-producing the Boomerang fighter for the Royal Australian Air Force (RAAF), CAC began design work on a fully-fledged interceptor and escort fighter. Because the Boomerang had become more and more obsolete against Japanese fighters like the Mitsubishi A6M Zero, Sir Lawrence Wackett (as head of CAC) proposed designing a new high-performance fighter from scratch. Fred David, who had designed the Boomerang, was to lead an in-house design team at CAC. In June 1943, the design concept proposal was approved by the government and RAAF, which issued ...

Commonwealth Aircraft Corporation
The Commonwealth Aircraft Corporation (CAC) was an Australian aircraft manufacturer. The CAC was established in 1936, to provide Australia with the capability to produce military aircraft and engines. History In 1935 the Chief General Manager of BHP, Essington Lewis, visited Europe and formed the view that war was probable. On his return to Australia, concerned at the lack of manufacturing capabilities there and at the possibility of aircraft not being available from 'traditional' (i.e. British) sources during wartime, he commenced a lobbying campaign to convince the Government of Australia to establish a modern aircraft industry. The government required little persuasion and encouraged negotiations between a number of Australian companies. The outcome of these negotiations, begun in August 1935, was the formation of CAC the following year. Initially the companies involved were BHP, General Motors-Holden and Broken Hill Associated Smelter. These were joined by Imperial Chemical ...

Pratt & Whitney R-2800
The Pratt & Whitney R-2800 Double Wasp is an American twin-row, 18-cylinder, air-cooled radial aircraft engine with a displacement of , and is part of the long-lived Wasp family of engines. The R-2800 saw widespread use in many important American aircraft during and after World War II. During the war years, Pratt & Whitney continued to develop new ideas to upgrade the engine, including water injection for takeoff in cargo and passenger planes and to give emergency power in combat. Design and development First run in 1937, near the time that the larger competing 18-cylinder Wright Duplex-Cyclone's development had been started in May of that year, the displacement R-2800 was first-flown by 1940, one year before the Duplex-Cyclone. The Double Wasp was more powerful than the world's only other modern 18-cylinder engine, the Gnome-Rhône 18L of . The Double Wasp was much smaller in displacement than either of the other 18-cylinder designs, and heat dissipation was a gr ...

Boeing XF8B
The Boeing XF8B (Model 400) was a single-engine aircraft developed by Boeing during World War II to provide the United States Navy with a long-range shipboard fighter aircraft. The XF8B was intended for operation against the Japanese home islands from aircraft carriers outside the range of Japanese land-based aircraft. Designed for various roles including interceptor, long-range escort fighter, dive-bomber, and torpedo bomber, the final design embodied a number of innovative features in order to accomplish the various roles. Despite its formidable capabilities, the XF8B-1 never entered series production. Design and development The XF8B-1 was, at the time, the largest and heaviest single-seat, single-engine fighter developed in the United States. Boeing called the XF8B-1 optimistically, the "five-in-one fighter" (fighter, interceptor, dive bomber, torpedo bomber, or level bomber). It was powered by a single 3,000 hp (2,200 kW) Pratt & Whitney XR-4360-10 four-row 28-c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Machine Guns
A machine gun is a fully automatic, rifled autoloading firearm designed for sustained direct fire with rifle cartridges. Other automatic firearms such as automatic shotguns and automatic rifles (including assault rifles and battle rifles) are typically designed more for firing short bursts rather than continuous firepower, and are not considered true machine guns. As a class of military kinetic projectile weapon, machine guns are designed to be mainly used as infantry support weapons and generally used when attached to a bipod or tripod, a fixed mount or a heavy weapons platform for stability against recoils. Many machine guns also use belt feeding and open bolt operation, features not normally found on other infantry firearms. Machine guns can be further categorized as light machine guns, medium machine guns, heavy machine guns, general purpose machine guns and squad automatic weapons. Similar automatic firearms of caliber or more are classified as autocannons, rat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rotol
Dowty Propellers is a British engineering company based in Brockworth, Gloucestershire that specialises in the manufacture, repair and overhaul of propellers and propeller components for customers around the world. It is owned by General Electric, forming part of its GE Aviation Systems division. History The company was formed as Rotol Airscrews in 1937 by Rolls-Royce and Bristol Engines to take over both companies' propeller development, the market being too small to support more than one company. The name is a contraction of "ROlls-Royce" and "BrisTOL". Rotol's propellers were always considered leading edge, its models equipping the Hawker Hurricane, Supermarine Spitfire, and many other Second World War-era aircraft. By the end of the war it had introduced the first five-bladed propeller to see widespread use, used on late-model Spitfires. In 1943 the company changed its name from Rotol Airscrews Limited to Rotol Limited, and in 1952 it acquired British Messier Limited, a ...

Rolls-Royce Griffon 61
The Rolls-Royce Griffon is a British 37-litre (2,240 cu in) capacity, 60-degree V-12, liquid-cooled aero engine designed and built by Rolls-Royce Limited. In keeping with company convention, the Griffon was named after a bird of prey, in this case the griffon vulture. Design work on the Griffon started in 1938 at the request of the Fleet Air Arm, for use in new aircraft designs such as the Fairey Firefly. In 1939 it was also decided that the engine could be adapted for use in the Spitfire. Development was stopped temporarily to concentrate efforts on the smaller Merlin and the 24-cylinder Vulture; the engine did not go into production until the early 1940s. The Griffon was the last in the line of V-12 aero engines to be produced by Rolls-Royce with production ceasing in 1955. Griffon engines remain in Royal Air Force service today with the Battle of Britain Memorial Flight and power the last remaining airworthy Avro Shackleton. Design and development Origins Acc ...

NACA Airfoil
The NACA airfoils are airfoil shapes for aircraft wings developed by the National Advisory Committee for Aeronautics (NACA). The shape of the NACA airfoils is described using a series of digits following the word "NACA". The parameters in the numerical code can be entered into equations to precisely generate the cross-section of the airfoil and calculate its properties. Origins NACA initially developed the numbered airfoil system which was further refined by the United States Air Force at Langley Research Center. According to the NASA website: Four-digit series The NACA four-digit wing sections define the profile by: # First digit describing maximum camber as percentage of the chord. # Second digit describing the distance of maximum camber from the airfoil leading edge in tenths of the chord. # Last two digits describing maximum thickness of the airfoil as percent of the chord. For example, the NACA 2412 airfoil has a maximum camber of 2% located 40% (0.4 chords) from the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Flight Lieutenant
Flight lieutenant is a junior commissioned rank in air forces that use the Royal Air Force (RAF) system of ranks, especially in Commonwealth countries. It has a NATO rank code of OF-2. Flight lieutenant is abbreviated as Flt Lt in the Indian Air Force (IAF) and RAF, and as FLTLT in the Pakistan Air Force (PAF), Royal Australian Air Force (RAAF) and Royal New Zealand Air Force (RNZAF) and has sometimes also been abbreviated as F/L in many services; it has never been correctly abbreviated as "lieutenant". A flight lieutenant ranks above flying officer and below a squadron leader and is sometimes used as an English language translation of a similar rank in non-English-speaking countries. The rank originated in the Royal Naval Air Service (RNAS) in 1914. It fell into abeyance when the RNAS merged with the Royal Flying Corps during the First World War but was revived in 1919 in the post-war RAF. An RAF flight lieutenant is the equivalent of a lieutenant in th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
