Bréguet 693
The Bréguet 690 and its derivatives were a series of light twin-engine ground-attack aircraft that were used by the French Air Force in World War II. The aircraft was intended to be easy to maintain, forgiving to fly, and capable of at . The type's sturdy construction was frequently demonstrated and the armament was effective. French rearmament began two years later than that in Britain and none of these aircraft were available in sufficient numbers to make a difference in 1940. Design and development Bréguet 690 The Bréguet 690 had begun life in 1934 as the Bre 630, the Bréguet Aviation entry for the (STAé, Aeronautical Technical Service) specification of October 1934 along with the Hanriot H 220, Loire-Nieuport LN-20, Romano R.110 and the Potez 630. The Bréguet 630 was a twin-engined monoplane with twin tailplanes and Hispano-Suiza 14AB 02/03 (port and starboard) 14-cylinder air-cooled radial engines, both rotating inwards to limit torque problems if one engine fai ...

Tailplane
A tailplane, also known as a horizontal stabilizer, is a small lift (force), lifting surface located on the tail (empennage) behind the main lifting surfaces of a fixed-wing aircraft as well as other non-fixed-wing aircraft such as helicopters and gyroplanes. Not all fixed-wing aircraft have tailplanes. Canard (aeronautics), Canards, tailless aircraft, tailless and flying wing aircraft have no separate tailplane, while in V-tail aircraft the vertical stabilizer, rudder, and the tail-plane and elevator are combined to form two diagonal surfaces in a V layout. The function of the tailplane is to provide stability and control. In particular, the tailplane helps adjust for changes in position of the center of pressure (fluid mechanics), centre of pressure or centre of gravity caused by changes in speed and attitude, fuel consumption, or dropping cargo or payload. Tailplane types The tailplane comprises the tail-mounted fixed horizontal stabilizer and movable Elevator (aeronautics), ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Self-sealing Fuel Tank
A self-sealing fuel tank (SSFT) is a type of fuel tank, typically used in aircraft fuel tanks or fuel bladders, that prevents them from leaking fuel and igniting after being damaged. Typical self-sealing tanks have layers of rubber and reinforcing fabric, one of vulcanized rubber and one of untreated natural rubber, which can absorb fuel when it comes into contact with it. When a fuel tank is punctured the fuel seeps into these layers, causing the untreated layer to swell, closing and thus sealing the puncture. A similar concept is also employed for making self-sealing run-flat tires. History World War I George J. Murdock applied for the patent "War Aeroplane Fuel Tanks" on February 7, 1917 but was temporarily blocked by an order of the Federal Trade Commission, on February 6, 1918, to keep any discussion or publication of the invention secret. The order was rescinded by the United States Patent Office on September 26, 1918 and Murdock was eventually granted "Self-Punctur ...

Vehicle Armour
Military vehicles are commonly armoured (or armored; American and British English spelling differences#-our, -or, see spelling differences) to withstand the impact of Fragmentation (weaponry), shrapnel, bullets, Shell (projectile), shells, Rocket (weapon), rockets, and missiles, protecting the personnel inside from enemy fire. Such vehicles include armoured fighting vehicles like tanks, aircraft, and ships. Civilian vehicles may also be armoured. These vehicles include cars used by officials (e.g., Official state car, presidential limousines), reporters and others in conflict zones or where violent crime is common. Civilian Armored car (valuables), armoured cars are also routinely used by security firms to carry money or valuables to reduce the risk of highway robbery or the Carjacking, hijacking of the cargo. Armour may also be used in vehicles to protect from threats other than a deliberate attack. Some spacecraft are equipped with specialised armour to protect them against im ...

Fuselage
The fuselage (; from the French language, French ''fuselé'' "spindle-shaped") is an aircraft's main body section. It holds Aircrew, crew, passengers, or cargo. In single-engine aircraft, it will usually contain an Aircraft engine, engine as well, although in some amphibious aircraft the single engine is mounted on a hardpoint, pylon attached to the fuselage, which in turn is used as a floating Hull (watercraft), hull. The fuselage also serves to position the Flight control surfaces, control and Stabilizer (aeronautics), stabilization surfaces in specific relationships to Wing, lifting surfaces, which is required for aircraft stability and maneuverability. Types of structures Truss structure This type of structure is still in use in many lightweight aircraft using welding, welded steel tube trusses. A box truss fuselage structure can also be built out of wood—often covered with plywood. Simple box structures may be rounded by the addition of supported lightweight strin ...

Bomb
A bomb is an explosive weapon that uses the exothermic reaction of an explosive material to provide an extremely sudden and violent release of energy. Detonations inflict damage principally through ground- and atmosphere-transmitted mechanical stress, the impact and penetration of pressure-driven projectiles, pressure damage, and explosion-generated effects. Bombs have been utilized since the 11th century starting in East Asia. The term ''bomb'' is not usually applied to explosive devices used for civilian purposes such as construction or mining, although the people using the devices may sometimes refer to them as a "bomb". The military use of the term "bomb", or more specifically aerial bomb action, typically refers to airdropped, unpowered explosive weapons most commonly used by air forces and naval aviation. Other military explosive weapons not classified as "bombs" include shells, depth charges (used in water), or land mines. In unconventional warfare, other names ...

Autocannon
An autocannon, automatic cannon or machine cannon is a automatic firearm, fully automatic gun that is capable of rapid-firing large-caliber ( or more) armour-piercing, explosive or incendiary ammunition, incendiary shell (projectile), shells, as opposed to the smaller-caliber kinetic projectiles (bullets) fired by a machine gun. Autocannons have a longer effective range and greater terminal ballistics, 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 gun barrel, barrel. When multiple rotating barrels are involved, such a weapon is referred to as a "rotary autocannon" or "rotary cannon". If it uses a single barrel with a rotating cylinder with multiple chambers, it is known as a "revolver autocannon" or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ratier
Ratier-Figeac is an aircraft components manufacturer in Figeac, France. From 1926 until 1930 it also built a car with a 746 cc overhead camshaft engine. From 1959 until 1962 Ratier made motorcycles, having taken over the motorcycle business of the Centre d'Études de Moteurs à Explosion et à Combustion ( CEMEC). The engines were flat-twins derived from Second World War BMW designs. History Ratier was originally a joinery firm. By the outbreak of the first world war, the company was specializing in propeller blades for the aircraft of the French Air Force. Afterwards it produced for the French mail service Aéropostale all the way through its heyday of the 1930s when the service broke many flight records. The factory was originally in Malakoff and then transferred to Montrouge. Much of its workload consisted of the contract work it received from Citroën to produce the Citroenette, a child's pedal-car. Paulin Ratier fabricated a prototype propeller-car which never made it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Strafing
Strafing is the military practice of attacking ground targets from low-flying aircraft using aircraft-mounted automatic weapons. Less commonly, the term is used by extension to describe high-speed firing runs by any land or naval craft such as fast boats, using smaller-caliber weapons and targeting stationary or slowly-moving targets. Etymology The word is an adaptation of German ''strafen'' (), to punish, specifically from the humorous adaptation of the German anti-British slogan '' Gott strafe England'' (May God punish England), dating back to World War I. Description Guns used in strafing range in caliber from machine guns, to autocannon or rotary cannon. Although ground attack using automatic weapons fire is very often accompanied with bombing or rocket fire, the term "strafing" does not specifically include the last two. The term "strafing" can cover either fixed guns, or aimable (flexible) guns. Fixed guns firing directly ahead tend to be more predominant on ...

MAC 1934
The MAC 1934 is a machine gun of French origin. It is effectively the aircraft variant of the Reibel machine gun. History In 1934, the ''Manufacture d'Armes de Châtellerault'' ( Châtellerault weapons manufacturing company, often shortened to ''MAC'') completed the development of the MAC 1934 machine gun to replace the Darne mod. 1933 machine gun aboard aircraft of the ''Armée de l'Air''. Essentially a faster-firing variant of the mitrailleuse mle 1931, and using the same 7.5 mm MAS ammunition, the MAC 34 worked by gas operation and was fed from drum magazines. Two main variants, sharing common parts, were introduced: * the ''type tourelle'' (turret model), fed from 100-round replaceable magazines, was used in flexible mountings, where it was generally fitted with an Alkan 1935 reflector gunsight. * the ''type aile'' (wing model) fed from a 300- or 500-round drum magazine, was used for fixed mountings. Because it used an open bolt action, the MAC 34 could not be fitted wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hispano-Suiza HS
Hispano-Suiza () is a Spanish automotive company. It was founded in 1904 by Marc Birkigt and 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 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. The relaunch of Hispano Suiza Cars has been made by the same founding family (4th generation of the Suqué Mateu Family), the company is part of the Peralada Group (owned as well by the Suqué Mateu family) in 2019 with a fully-electric 1,119 HP hypercar called Hispano-Suiza ...
