CAC Woomera
The CAC Woomera, also known as the CAC CA-4 and CAC CA-11, was an Australian bomber aircraft that was designed and constructed by the Commonwealth Aircraft Corporation during World War II. The order for the Woomera was cancelled before it became operational with the Royal Australian Air Force (RAAF). Design and development In early 1939, the Australian Government ordered large numbers of Bristol Beaufort bombers, with major components to be built in a variety of locations, including railway workshops, and in doing so it by-passed the local aircraft company, the Commonwealth Aircraft Corporation. CAC, under Sir Lawrence Wackett, began work on its own design, hoping to out-perform the Beaufort by building a machine that could serve as both a torpedo-bomber and dive bomber. To keep down weight, Wackett dispensed with traditional self-sealing fuel tanks and opted to make the wing cavities liquid-tight, and thus serve as fuel storage. The Australian Government was initially uninterest ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Light Bomber
A light bomber is a relatively small and fast type of Military aircraft, military bomber Fixed-wing aircraft, aircraft that was primarily employed before the 1950s. Such Fixed-wing aircraft, aircraft would typically not carry more than one ton of Explosive weapon, ordnance. The earliest light bombers were intended to drop their Aerial bomb, bombs in High level bombing, level flight over a target. During World War I some air forces began to distinguish between light bombers and the earliest purpose-built attack aircraft which carried out ground attack, close air support, Anti-surface warfare, anti-shipping and similar missions. After World War I, attack aircraft were typically identifiable by their ability to carry multiple fixed machine guns, Autocannon, automatic cannons and Rocket (weapon), rockets in addition to Aerial bomb, bombs. Light bombers have often served as attack aircraft and vice versa. Purpose-built light bombers disappeared from military aviation by the end of ...

North American P-51
The North American Aviation P-51 Mustang is an American long-range, single-seat fighter and fighter-bomber used during World War II and the Korean War, among other conflicts. The Mustang was designed in April 1940 by a team headed by James H. Kindelberger of North American Aviation (NAA) in response to a requirement of the British Purchasing Commission. The Purchasing Commission approached North American Aviation to build Curtiss P-40 fighters under license for the Royal Air Force (RAF). Rather than build an old design from another company, North American Aviation proposed the design and production of a more modern fighter. The prototype NA-73X airframe was rolled out on 9 September 1940, 102 days after the contract was signed, and first flew on 26 October. The Mustang was designed to use the Allison V-1710 engine, which had limited high-altitude performance in its earlier variants. The aircraft was first flown operationally by the RAF as a tactical-reconnaissance aircraft ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mark 13 Torpedo
The Mark 13 torpedo was the U.S. Navy's most common aerial torpedo of World War II. It was the first American torpedo to be originally designed for launching from aircraft only. They were also used on PT boats. Design Originating in a 1925 design study, the Mark 13 was subject to changing USN requirements through its early years with resulting on-and-off development. Early models—even when dropped low to the water at slow speeds—were prone to running on the surface, or not running at all. By late 1944, the design had been modified to allow reliable drops from as high as , at speeds up to . The final Mark 13 weighed ; of this was the high explosive Torpex.NavWeaps (18 February 2005).USA Torpedoes of WWII. Retrieved 2 August 2005.

British 18-inch Torpedo
There have been a number of 18-inch torpedoes in service with the United Kingdom. These have been used on ships of the Royal Navy and aircraft of both the Fleet Air Arm and Royal Air Force, while Royal Navy surface ships and submarines use 21-inch torpedoes. The British "18-inch" torpedoes were in diameter, beginning with the "Fiume" Whitehead torpedo of 1890. 45 cm "Fiume" (Whitehead) torpedo First introduced into British service in 1894. * Year : about 1888 * Weight : * Length : * Warhead : wet gun-cotton * Performance : for * Propulsion : Compressed air Mark V Used on the River-class and 1905 Tribal-class destroyers. * Year : about 1899 * Weight : * Warhead : including pistol * Propulsion : Compressed air Mark VI Used on destroyers of the early 1900s. * Year : about 1904 * Performance : for or for * Propulsion : Compressed air Mark VII and VII* Introduced on the 1908 members of the 1905 Tribal class destroyers.

Vickers K Machine Gun
The Vickers K machine gun, known as the Vickers Gas Operated (Vickers G.O.) or Gun, Machine, Vickers G.O. .303-inch in British service, was a rapid-firing machine gun developed and manufactured for use in aircraft by Vickers-Armstrongs. The high rate of fire was needed for the short period of time when the gunner would be able to fire at an attacking aircraft. The weapon was adopted for land use during World War II. Development The Vickers K was a development of the Vickers-Berthier (VB) light machine gun, adopted in 1932 by the Indian Army.Weeks, John, ''World War II Small Arms'', New York: Galahad Books (1979), , p. 88-89 The VB, like the Bren light machine gun, used a locking tilting breechblock. However, unlike the Bren, the VB locked its breech only at the last moment of forward travel and this enabled the development of the Vickers K also known as the "Vickers Gas Operated" (VGO) or "Vickers GO" . With lighter moving parts and the VB locking design, the Vickers K had a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Autocannon
An autocannon, automatic cannon or machine cannon is a fully automatic gun that is capable of rapid-firing large-caliber ( or more) armour-piercing, explosive or incendiary shells, as opposed to the smaller-caliber kinetic projectiles (bullets) fired by a machine gun. Autocannons have a longer effective range and greater terminal performance than machine guns, due to the use of larger/heavier munitions (most often in the range of , but bigger calibers also exist), but are usually smaller than tank guns, howitzers, field guns or other artillery. When used on its own, the word "autocannon" typically indicates a non-rotary weapon with a single barrel. When multiple rotating barrels are involved, such a weapon is referred to as a "rotary autocannon" or occasionally "rotary cannon", for short (particularly on aircraft). Autocannons are heavy weapons that are unsuitable for use by infantry. Due to the heavy weight and recoil, they are typically installed on fixed mounts, whe ...

Hispano-Suiza HS
Hispano-Suiza () is a Spanish automotive–engineering company. It was founded in 1904 by Marc Birkigt and Damian Mateu as an automobile manufacturer and eventually had several factories in Spain and France that produced luxury cars, aircraft engines, trucks and weapons. In 1923, its French luxury car arm became a semi-autonomous partnership with the Spanish parent company. In 1946, the Spanish parent company sold all of its Spanish automotive assets to Enasa, a Spanish state-owned vehicle manufacturer, and the French arm continued as an independent aviation engine and components manufacturer under the Hispano-Suiza name. In 1968, Hispano-Suiza was taken over by the aerospace company Snecma, which is now part of the French Safran Group. An attempt to relaunch the marque was made by the company Hispano Suiza Cars associated with the Peralada Group (owned by the Suqué Mateu family) in 2019 with a fully-electric car.

Machine Gun
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 aut ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
M1919 Browning Machine Gun
The M1919 Browning is a .30 caliber medium machine gun that was widely used during the 20th century, especially during World War II, the Korean War, and the Vietnam War. The M1919 saw service as a light infantry, coaxial, mounted, aircraft, and anti-aircraft machine gun by the U.S. and many other countries. The M1919 was an air-cooled development of the standard US machine gun of World War I, the John M. Browning-designed water-cooled M1917. The emergence of general-purpose machine guns in the 1950s pushed the M1919 into secondary roles in many cases, especially after the arrival of the M60 in US Army service. The United States Navy also converted many to 7.62 mm NATO, and designated them Mk 21 Mod 0; they were commonly used on riverine craft in the 1960s and 1970s in Vietnam. Many NATO countries also converted their examples to 7.62 mm caliber, and these remained in service well into the 1990s, as well as up to the present day in some countries. Operation Loading ...

Pratt & Whitney R-1830-S3C3-G Twin Wasp
The Pratt & Whitney R-1830 Twin Wasp is an American air-cooled radial aircraft engine. It displaces and its bore and stroke are both . The design traces its history to 1929 experiments at Pratt & Whitney on twin-row designs. Production began in 1932 and it was widely used during the 1930s. It was selected as the power plant for both the four-engined Consolidated B-24 Liberator heavy bomber and the twin-engined Douglas DC-3 transport, two of the most-produced aircraft. The production run of 173,618 R-1830 examples makes it the most-produced aviation engine in history. A further developed version, the R-2000, was produced starting in 1942. The R-2000 was "bored-out" to and had a number of other minor changes to improve fuel economy and allow it to run at higher power ratings on lower- octane fuel. The primary user of the R-2000 was the Douglas DC-4. Mostly retired today, the R-1830 is still used on Douglas DC-3 and various museum aircraft and warbirds seen at airshows. I ...

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 l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
