P-66 Vanguard
The Vultee P-66 Vanguard was a United States Army Air Forces fighter aircraft. It was initially ordered by Sweden, but by the time the aircraft were ready for delivery in 1941, the United States would not allow them to be exported, designating them as P-66s and retaining them for defensive and training purposes. Eventually, a large number were sent to China where they were pressed into service as combat aircraft with mixed results. Design and development The Vultee Vanguard was the product of an idea conceived in the late 1930s by the Vultee Aircraft Division of the Aviation Manufacturing Corporation of developing four aircraft designed for different roles from a set of common wings and aft fuselage and tail assemblies. The company assigned four model designations: V-48 to a single-seat fighter, BC-51 to a basic combat trainer, B-54 to an advanced trainer, and BC-54D as a basic trainer. Eventually, the BC-51 would become the Army Air Corps BC-3 and the BC-54D, the BT-13. In 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Vance Breese
Vance Breese (1904–1973) was an American Aeronautical engineer, aviation engineer and test pilot. Early years Vance Breese was born in Keystone, Washington, on April 20, 1904. His education, in his own words was: "various engineering extension courses." More than an engineer, he devoted his life to aviation. Aviation career In 1926, Breese founded the (Vance) Breese Aircraft Company at Mills Field, San Francisco and was its president, from 1927 to 1934. Competing in the 1926 National Air Tour, flying a Ryan M-1 monoplane with a Wright J-4 engine, he finished in eighth place, although he had actually been in first place when he reached Cleveland, Ohio, one of 14 cities in the competition. During the 15-day event which was the second annual commercial airplane reliability tour, Breese carried J. B. Alexander and A. L. Hufford as passengers. Aviation companies The companies that Breese operated, appeared under various names, in 1927 as the Breese-(Arthur F. "Pop") Wilde Aircraft ...

Nakajima Ki-44
The Nakajima Ki-44 ''Shoki'' (鍾馗, " Devil Queller") was a single-seat fighter-interceptor which was developed by the Nakajima Aircraft Company and operated by the Imperial Japanese Army from 1942 to 1945 during World War II. Its official designation was Army Type 2 Single-Seat Fighter (二式単座戦闘機) and its Allied reporting name was Tojo. The design and development of the Ki-44 differed greatly from that of other Japanese fighters of the time, incorporating speed and rate-of-climb in preference to maneuverability.Millman, 2011, pp.1–8 This was a result of a need for a heavy fighter aircraft that followed a more offensive doctrine and the Ki-44 is often classified as an Air Defence Fighter.Bueschel, 1971 Its development ran almost in parallel to its predecessor, the lighter and nimbler Nakajima Ki-43, and yet the two aircraft differed. The Ki-44 had a higher landing speed but was less maneuverable. These were concerns for pilots who would compare it to the Ki-43 ...

Nakajima Ki-43
The Nakajima Ki-43 ''Hayabusa'' (, "Peregrine falcon", "Army Type 1 Fighter" ) is a single-engine land-based tactical fighter used by the Imperial Japanese Army Air Service in World War II. The Allied reporting name was "Oscar", but it was often called the "Army Zero" by American pilots because it bore a certain resemblance to the Mitsubishi A6M Zero, the Imperial Japanese Navy's counterpart to the Ki-43. Both aircraft had generally similar layout and lines, and also used essentially the same Nakajima Sakae radial engine, with similar round cowlings and bubble-type canopies (the ''Oscar'''s being distinctly smaller and having much less framing than the A6M). While relatively easy for a trained eye to tell apart with the "finer" lines of the Ki-43's fuselage – especially towards the tail – and more tapered wing planform; in the heat of battle, given the brief glimpses and distraction of combat, Allied aviators frequently made mistakes in enemy aircraft identification in th ...

Nakajima Aircraft Company
The was a prominent Japanese aircraft manufacturer and aviation engine manufacturer throughout World War II. It continues as the car and aircraft manufacturer Subaru. History The Nakajima Aircraft company was Japan's first aircraft manufacturer, and was founded in 1918 by Chikuhei Nakajima, a naval engineer, and Seibei Kawanishi, a textile manufacturer, as . In 1919, the two founders split and Nakajima bought out Nihon Aircraft's factory with tacit help from the Imperial Japanese Army. The company was renamed Nakajima Aircraft Company in 1919. The company's manufacturing facilities consisted of the following: * Tokyo plant * Musashino plant * Donryu plant * Ota plant, near Ōta Station. Visited by Emperor Shōwa on November 16, 1934.

American Volunteer Group
The American Volunteer Groups were volunteer air units organized by the United States government to aid the Nationalist government of China against Japan in the Second Sino-Japanese War. The only unit to actually see combat was the 1st AVG, popularly known as the Flying Tigers. To aid the Nationalist government of China and to put pressure on Japan, President Franklin Roosevelt in April 1941 authorized the creation of a clandestine "Special Air Unit" consisting of three combat groups equipped with American aircraft and staffed by aviators and technicians to be recruited from the U.S. Army, Navy and Marine Corps for service in China. The program was fleshed out in the winter of 1940–1941 by Claire Lee Chennault, then an air advisor to the Chinese Nationalist leader Chiang Kai-shek, and Lauchlin Currie, a young economist in the Roosevelt White House. They envisioned a small air corps of 500 combat aircraft, although in the end, the number was reduced to 200 fighters and 66 light ...

Lend-Lease
Lend-Lease, formally the Lend-Lease Act and introduced as An Act to Promote the Defense of the United States (), was a policy under which the United States supplied the United Kingdom, the Soviet Union and other Allied nations with food, oil, and materiel between 1941 and 1945. It was given on the basis that such help was essential for the defense of the United States; this aid included warships and warplanes, along with other weaponry. It was signed into law on March 11, 1941, and ended on September 20, 1945. In general, the aid was free, although some hardware (such as ships) were returned after the war. Canada, already a belligerent, supplemented its aid to Great Britain with a similar, smaller program called Mutual Aid. A total of $50.1 billion (equivalent to $ in ) worth of supplies was shipped, or 17% of the total war expenditures of the U.S. In all, $31.4 billion went to the United Kingdom, $11.3 billion to the Soviet Union, $3.2 billion to France, $1.6 billion to Chin ...

Ground Loop (aviation)
In aviation, a ground loop is a rapid rotation of a fixed-wing aircraft in the horizontal plane ( yawing) while on the ground. Aerodynamic forces may cause the advancing wing to rise, which may then cause the other wingtip to touch the ground. In severe cases (particularly if the ground surface is soft), the inside wing can dig in, causing the aircraft to swing violently or even cartwheel. In their early gliding experiments, the Wright Brothers referred to this action as ''well-digging''. Looping phenomenon In powered aeroplanes, the ground loop phenomenon is predominantly associated with aircraft that have conventional landing gear, due to the centre of gravity being positioned behind the main wheels. It may also occur with tricycle landing gear if excessive load is applied to the nosewheel, a condition known as wheel-barrowing. If the aircraft heading is different from the aircraft's direction of motion, a sideways force is exerted on the wheels. If this force is in front of t ...

Attack On Pearl Harbor
The attack on Pearl HarborAlso known as the Battle of Pearl Harbor was a surprise military strike by the Imperial Japanese Navy Air Service upon the United States against the naval base at Pearl Harbor in Honolulu, Territory of Hawaii, just before 8:00a.m. (local time) on Sunday, December 7, 1941. The United States was a neutral country at the time; the attack led to its formal entry into World War II the next day. The Japanese military leadership referred to the attack as the Hawaii Operation and Operation AI, and as Operation Z during its planning. Japan intended the attack as a preventive action. Its aim was to prevent the United States Pacific Fleet from interfering with its planned military actions in Southeast Asia against overseas territories of the United Kingdom, the Netherlands, and those of the United States. Over the course of seven hours there were coordinated Japanese attacks on the US-held Philippines, Guam, and Wake Island and on the British Empire ...
