Tachikawa Ki-17
The was a basic training aircraft of the Imperial Japanese Army Air Force built by Tachikawa Aircraft Company Ltd in the 1930s. It was known to the Allies under the nickname of ''Cedar'' during World War II. Design and development The Ki-9 was originally planned to be manufactured in two versions using the same basic airframe, but with different engines for service as either a primary or intermediate trainer. However, when the lower-powered form proved to be unsuitable due a center of gravity issue, design of a new airframe was ordered for the basic trainer version, and was given the new designation of Ki-17. Compared to the Ki-9, the Ki-17 had equal-span wings, a slimmer fuselage and a revised tailplane. It was powered by a Hitachi Ha-13a radial engine. The first prototype flew in July 1935. The only major change made to subsequent production aircraft was the deletion of the upper-wing ailerons to eliminate oversensitive control inputs. Operational history The Ki-17 was i ...

Biplane
A biplane is a fixed-wing aircraft with two main wings stacked one above the other. The first powered, controlled aeroplane to fly, the Wright Flyer, used a biplane wing arrangement, as did many aircraft in the early years of aviation. While a biplane wing structure has a structural advantage over a monoplane, it produces more drag than a monoplane wing. Improved structural techniques, better materials and higher speeds made the biplane configuration obsolete for most purposes by the late 1930s. Biplanes offer several advantages over conventional cantilever monoplane designs: they permit lighter wing structures, low wing loading and smaller span for a given wing area. However, interference between the airflow over each wing increases drag substantially, and biplanes generally need extensive bracing, which causes additional drag. Biplanes are distinguished from tandem wing arrangements, where the wings are placed forward and aft, instead of above and below. The term is also ...

1930s Japanese Military Trainer Aircraft
Year 193 ( CXCIII) was a common year starting on Monday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Sosius and Ericius (or, less frequently, year 946 ''Ab urbe condita''). The denomination 193 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years. Events By place Roman Empire * January 1 – Year of the Five Emperors: The Roman Senate chooses Publius Helvius Pertinax, against his will, to succeed the late Commodus as Emperor.

List Of Military Aircraft Of Japan
This list of military aircraft of Japan includes project, prototype, pre-production and operational types regardless of era. This includes both domestically developed Japanese designs, licensed variants of foreign designs, and foreign-produced aircraft that served in the military of Japan. Japanese names are used here, not World War II Allied codenames. The prefix "Ki" in this list is an abbreviation of "Kitai", meaning "airframe", and was used only by the Imperial Japanese Army Air Force. "Ki" should be read as one word.

De Havilland Tiger Moth
The de Havilland DH.82 Tiger Moth is a 1930s British biplane designed by Geoffrey de Havilland and built by the de Havilland Aircraft Company. It was operated by the Royal Air Force (RAF) and other operators as a primary trainer aircraft. In addition to the type's principal use for ''ab initio'' training, the Second World War had RAF Tiger Moths operating in other capacities, including maritime surveillance and defensive anti-invasion preparations; some aircraft were even outfitted to function as armed light bombers. The Tiger Moth remained in service with the RAF until it was replaced by the de Havilland Chipmunk during the early 1950s. Many of the military surplus aircraft subsequently entered into civilian operation. Many nations have used the Tiger Moth in both military and civilian applications, and it remains in widespread use as a recreational aircraft. It is still occasionally used as a primary training aircraft, particularly for those pilots wanting to gain exper ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Aileron
An aileron (French for "little wing" or "fin") is a hinged flight control surface usually forming part of the trailing edge of each wing of a fixed-wing aircraft. Ailerons are used in pairs to control the aircraft in roll (or movement around the aircraft's longitudinal axis), which normally results in a change in flight path due to the tilting of the lift vector. Movement around this axis is called 'rolling' or 'banking'. Considerable controversy exists over credit for the invention of the aileron. The Wright brothers and Glenn Curtiss fought a years-long legal battle over the Wright patent of 1906, which described a method of wing-warping to achieve lateral control. The brothers prevailed in several court decisions which found that Curtiss's use of ailerons violated the Wright patent. Ultimately, the First World War compelled the U.S. Government to legislate a legal resolution. A much earlier aileron concept was patented in 1868 by British scientist Matthew Piers Watt Bou ...
