Hitachi TR.2
The Hitachi TR.1 was a small airliner developed in Japan in 1938, produced in small numbers as the TR.2. It was a low-wing, cantilever monoplane with retractable tailwheel undercarriage and a fully enclosed cabin. The design strongly resembled the Airspeed Envoy that it was intended to replace in Japanese airline service. Testing of the TR.1 prototype commenced on 8 April 1938 at Haneda Airport , officially , and sometimes called as Tokyo Haneda Airport or Haneda International Airport , is one of two international airports serving the Greater Tokyo Area, the other one being Narita International Airport (NRT). It serves as the primary ..., but it suffered a serious accident on 22 June due to a landing in which one of the main undercarriage units failed to extend. The TR.2 was a revised and strengthened design with a larger wing area, and main undercarriage that only semi-retracted. Twelve examples were built in a small series, but performance was not as good as the TR.1, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Airspeed Envoy
The Airspeed AS.6 Envoy was a twin-engined light transport aircraft designed and produced by the British aircraft manufacturer Airspeed Ltd. The Envoy originated as a heavier twin-engine derivative of Airspeed's Courier light transport aircraft. Sharing much of its design with this earlier aircraft, it was relatively easy to develop; confidence in the project was so high that within a week of the prototype's maiden flight, it was performing as a display aircraft to the public. Quantity production of the Envoy had been initiated even before this first flight. Early on, Airspeed worked closely with the British engine manufacturer Wolseley Motors as both a key supplier and early custom of the Envoy; development subsequently branched out to a wide variety of engines and configurations. The majority of Envoys were produced by Airspeed at their facility at Portsmouth Aerodrome, Hampshire. The type was also produced overseas in Japan by Mitsubishi following the acquisition of a licen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Haneda Airport
, officially , and sometimes called as Tokyo Haneda Airport or Haneda International Airport , is one of two international airports serving the Greater Tokyo Area, the other one being Narita International Airport (NRT). It serves as the primary base of Japan's two major domestic airlines, Japan Airlines (Terminal 1) and All Nippon Airways (Terminal 2), as well as Air Do, Skymark Airlines, Solaseed Air, and StarFlyer. It is located in Ōta, Tokyo, south of Tokyo Station. Haneda was the primary international airport serving Tokyo until 1978; from 1978 to 2010, Haneda handled almost all domestic flights to and from Tokyo as well as "scheduled charter" flights to a small number of major cities in East and Southeast Asia, while Narita International Airport handled the vast majority of international flights from further locations. In 2010, a dedicated international terminal, currently Terminal 3, was opened at Haneda in conjunction with the completion of a fourth runway, allow ...

Gasuden Jimpu
The Gasuden Jimpu or Kamikaze (later produced by Hitachi) was a Japanese seven-cylinder air-cooled radial aircraft engine from the 1920s, 1930s and 1940s. It was the first aircraft engine produced by , often abbreviated to Gasuden, and the first production engine produced in Japan. It was produced in large numbers to power training and light aircraft before and during the Pacific War. Design and development The early development of aircraft in Japan was fully dependent on engines from abroad, although many of these designs were license built by Japanese companies. Gasuden was no exception, building Le Rhone rotaries in the early 1920s. However, by 1926, the company had gained enough experience to develop its own first engine. Taking inspiration from the Armstrong Siddeley Mongoose, the company developed a seven-cylinder star-shaped radial made of alloy and using an integral impellor-based carburettor. The prototype was first run in 1927 and was the first indigenous design to ac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radial Engine
The radial engine is a reciprocating type internal combustion engine configuration in which the cylinders "radiate" outward from a central crankcase like the spokes of a wheel. It resembles a stylized star when viewed from the front, and is called a "star engine" in some other languages. The radial configuration was commonly used for aircraft engines before gas turbine engines became predominant. Engine operation Since the axes of the cylinders are coplanar, the connecting rods cannot all be directly attached to the crankshaft unless mechanically complex forked connecting rods are used, none of which have been successful. Instead, the pistons are connected to the crankshaft with a master-and-articulating-rod assembly. One piston, the uppermost one in the animation, has a master rod with a direct attachment to the crankshaft. The remaining pistons pin their connecting rods' attachments to rings around the edge of the master rod. Extra "rows" of radial cylinders can be ...

1930s Japanese Airliners
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. Pertinax is forced to reorganize the handling of finances, which were wrecked under Commodus, to reestablish discipline in the Roman army, and to suspend the food programs established by Trajan, provoking the ire of the Praetorian Guard. * March 28 – Pertinax is assassinated by members of the Praetorian Guard, who storm the imperial palace.

Low-wing Aircraft
A monoplane is a fixed-wing aircraft configuration with a single mainplane, in contrast to a biplane or other types of multiplanes, which have multiple planes. A monoplane has inherently the highest efficiency and lowest drag of any wing configuration and is the simplest to build. However, during the early years of flight, these advantages were offset by its greater weight and lower manoeuvrability, making it relatively rare until the 1930s. Since then, the monoplane has been the most common form for a fixed-wing aircraft. Characteristics Support and weight The inherent efficiency of the monoplane is best achieved in the cantilever wing, which carries all structural forces internally. However, to fly at practical speeds the wing must be made thin, which requires a heavy structure to make it strong and stiff enough. External bracing can be used to improve structural efficiency, reducing weight and cost. For a wing of a given size, the weight reduction allows it to fly slower a ...

Aircraft First Flown In 1938
An aircraft is a vehicle that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil, or in a few cases the downward thrust from jet engines. Common examples of aircraft include airplanes, helicopters, airships (including blimps), gliders, paramotors, and hot air balloons. The human activity that surrounds aircraft is called ''aviation''. The science of aviation, including designing and building aircraft, is called ''aeronautics.'' Crewed aircraft are flown by an onboard pilot, but unmanned aerial vehicles may be remotely controlled or self-controlled by onboard computers. Aircraft may be classified by different criteria, such as lift type, aircraft propulsion, usage and others. History Flying model craft and stories of manned flight go back many centuries; however, the first manned ascent — and safe descent — in modern times took place by larger hot-air ...
