Curtiss P-40K Warhawk
The Curtiss P-40 Warhawk was a WWII fighter aircraft that was developed from the P-36 Hawk, via the P-37. Many variants were built, some in large numbers, under names including the Hawk, Tomahawk, and Kittyhawk. Allison-engined Model 75 XP-37 In early 1937, after realizing the Hawk 75 was inferior to more modern European designs, the USAAC ordered one P-36 to be modified with an Allison V-1710 inline engine. The prototype Hawk was fitted with a turbo-supercharged 1,150 hp (860 kW) Allison V-1710-11 engine as the XP-37 (company designation Model 75I). The cockpit was moved back towards the tail to make room for the massive supercharger, and the engine was cooled by two radiators on either side of the nose. Armament was one .30 M1919 Browning MG and one .50 M2 Browning MG mounted in the nose. The XP-37 was plagued with supercharger and visibility problems. YP-37 A further 13 Model 75Is were ordered in 1938 under the designation YP-37. These differed fro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Armistice Of 22 June 1940
The Armistice of 22 June 1940, sometimes referred to as the Second Armistice at Compiègne, was an agreement signed at 18:36 on 22 June 1940 near Compiègne, France by officials of Nazi Germany and the French Third Republic. It became effective at midnight on 25 June. Signatories for Germany included Wilhelm Keitel, a senior military officer of the Wehrmacht (the German armed forces), while those on the French side held lower ranks, including general Charles Huntziger. Following the decisive German victory in the Battle of France, the armistice established a German occupation zone in Northern and Western France that encompassed about three-fifths of France's European territory, including all English Channel and Atlantic Ocean ports. The remainder of the country was to be left unoccupied, although the new regime that replaced the Third Republic was mutually recognised as the legitimate government of all of Metropolitan France except Alsace–Lorraine. The French were also p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Curtiss XP-46
The Curtiss XP-46 was a 1940s American prototype fighter aircraft. It was a development of the Curtiss-Wright Corporation in an effort to introduce the best features found in European fighter aircraft in 1939 into a fighter aircraft which could succeed the Curtiss P-40, then in production. Design and development A United States Army Air Corps (USAAC) specification based upon a Curtiss proposal was the basis for an order placed in September 1939 for the XP-46. The requirements called for a single-engine, low-wing aircraft, slightly smaller than the P-40, and with a wide-track, inward-retracting landing gear. The selected powerplant was a 1,150 hp (858 kW) Allison V-1710-39 V-12 engine. The planned armament included two .50 in (12.7 mm) synchronized machine guns in the forward fuselage and provisions for eight .30 in (7.62 mm) wing-mounted guns. The USAAC later added requirements for self-sealing fuel tanks and 65 lb (29 kg) of armor, the we ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Flying Tigers
The First American Volunteer Group (AVG) of the Republic of China Air Force, nicknamed the Flying Tigers, was formed to help oppose the Japanese invasion of China. Operating in 1941–1942, it was composed of pilots from the United States Army Air Corps (USAAC), United States Navy, Navy (USN), and United States Marine Corps, Marine Corps (USMC), and was commanded by Claire Lee Chennault. Their Curtiss P-40 Warhawk, Curtiss P-40B Warhawk aircraft, marked with Chinese colors, flew under American control. Recruited under President Franklin Roosevelt's authority before Attack on Pearl Harbor, Pearl Harbor, their mission was to bomb Japan and defend the Republic of China, but many delays meant the AVG first flew in combat after the US and Japan declared war. The group consisted of three fighter aircraft, fighter Squadron (aviation), squadrons of around 30 aircraft each that trained in Burma before the American entry into World War II to defend the Republic of China against Empire ...

Nationalist Chinese Air Force
Nationalism is an idea or movement that holds that the nation should be congruent with the state. As a movement, it presupposes the existence and tends to promote the interests of a particular nation, Smith, Anthony. ''Nationalism: Theory, Ideology, History''. Polity, 2010. pp. 9, 25–30; especially with the aim of gaining and maintaining its sovereignty (self-governance) over its perceived homeland to create a nation-state. It holds that each nation should govern itself, free from outside interference (self-determination), that a nation is a natural and ideal basis for a polity, and that the nation is the only rightful source of political power. It further aims to build and maintain a single national identity, based on a combination of shared social characteristics such as culture, ethnicity, geographic location, language, politics (or the government), religion, traditions and belief in a shared singular history, and to promote national unity or solidarity.

Drop Tank
In aviation, a drop tank (external tank, wing tank or belly tank) is used to describe auxiliary fuel tanks externally carried by aircraft. A drop tank is expendable and often capable of being jettisoned. External tanks are commonplace on modern military aircraft and occasionally found in Civilian aircraft, civilian ones, although the latter are less likely to be discarded except in an emergency. Overview The primary disadvantage with drop tanks is that they impose a drag penalty on the aircraft. External fuel tanks will also increase the moment of inertia, thereby reducing Flight dynamics, roll rates for Air combat manoeuvring, air maneuvers. Some of the drop tank's fuel is used to overcome the added drag and weight of the tank. Drag in this sense varies with the square of the aircraft's speed. The use of drop tanks also reduces the number of external hardpoints available for weapons, reduces the weapon-carrying capacity and increases the aircraft's radar signature. Usually th ...

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 ...

Photo Reconnaissance
Aerial reconnaissance is reconnaissance for a military or strategic purpose that is conducted using reconnaissance aircraft. The role of reconnaissance can fulfil a variety of requirements including artillery spotting, the collection of imagery intelligence, and the observation of enemy maneuvers. History Early developments After the French Revolution, the new rulers became interested in using the balloon to observe enemy manoeuvres and appointed scientist Charles Coutelle to conduct studies using the balloon ''L'Entreprenant'', the first military reconnaissance aircraft. The balloon found its first use in the 1794 conflict with Austria, where in the Battle of Fleurus they gathered information. Moreover, the presence of the balloon had a demoralizing effect on the Austrian troops, which improved the likelihood of victory for the French troops. To operate such balloons, a new unit of the French military, the French Aerostatic Corps, was established; this organisation ...
