Itoh Emi 29
The Itoh Emi 29 ''Taihoku-go'' was a 1920s Japanese civil transport with its two passengers in a enclosed cabin. It was the first of this "limousine" type to be built in Japan; the only example flew the Osaka-Tokyo route for a while. Design and development The 1923 ''Taihoku-go'' (''Taipei'') was given its name since it was built to an order from Wen-Ta Shie, a pilot from Taiwan which was then under Japanese rule. It was the first Japanese-designed civil aircraft to enclose its passengers in a cabin, limousine style. Such aircraft had been developed in Europe soon after the end of World War I with conversions of war surplus machines, though luxurious accommodation for more passengers was provided in purpose-built types like the Westland Limousine as early as 1919. Generally the pilot was separated from the passengers or raised above them, in an open cockpit. The Emi 29 was a biplane#Bays, two bay biplane with wooden-structured, aircraft fabric covering, fabric-covered wings br ...

Itoh Emi 16
The Itoh Emi 16 ''Fuji-go'' (''Fuji''), built in 1920, was intended as a cheap and simple general purpose civil biplane but gained publicity with exhibition flights and successful speed and altitude contests against higher-powered fighter aircraft. Design and development Though the ''Fuji-go'' was best known for its successes in speed contests, it was designed as a multi-purpose, economical civil aircraft, powered by a war-surplus Le Rhône rotary engine and with a cost kept low by structural simplicities such as wings without sweep or stagger. It was a two bay biplane with a wooden structure and fabric covering. Its wings had rectangular plans apart from blunted tips, braced together with pairs of parallel interplane struts. Behind the engine the fuselage was rectangular in section with two open cockpits, one under the upper wing and the other for the pilot under its trailing edge, which had a small cut-out to improve the upward field of view. The forward cockpit coul ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Biplanes
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 (aerodynamics), 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. ...

V8 Engine
A V8 engine is an eight- cylinder piston engine in which two banks of four cylinders share a common crankshaft and are arranged in a V configuration. Origins The first known V8 was the Antoinette, designed by Léon Levavasseur, and built in 1904 by the French Antoinette company for use in speedboat racing, cars, and later, airplanes. Also in 1904, V8 engines began small-scale production by Renault and Buchet for use in race cars. Design V-angle Most engines use a V-angle (the angle between the two banks of cylinders) of 90 degrees. This angle results in good engine balance, which results in low vibrations. However, the downside is the greater width of the engine compared to those that use a smaller V-angle. V8 engines with a 60-degree V-angle were used in the 1996–1999 Ford Taurus SHO, the 2005–2011 Volvo XC90, and the 2006–2009 Volvo S80. The Ford engine used a 60-degree V-angle because it was based on a V6 engine with a 60-degree V-angle. ...

Landing Gear
Landing gear is the undercarriage of an aircraft or spacecraft that is used for taxiing, takeoff or landing. For aircraft, it is generally needed for all three of these. It was also formerly called ''alighting gear'' by some manufacturers, such as the Glenn L. Martin Company. For aircraft, Stinton makes the terminology distinction ''undercarriage (British) = landing gear (US)''. For aircraft, the landing gear supports the craft when it is not flying, allowing it to take off, land, and taxi without damage. Wheeled landing gear is the most common, with skis or Seaplane, floats needed to operate from snow/ice/water and skids for vertical operation on land. Retractable undercarriages fold away during flight, which reduces drag (physics), drag, allowing for faster airspeeds. Landing gear must be strong enough to support the aircraft and its design affects the weight, balance and performance. It often comprises three wheels, or wheel-sets, giving a tripod effect.

Balanced Rudder
Balanced rudders are used by both ships and aircraft. Both may indicate a portion of the rudder surface ahead of the hinge, placed to lower the control loads needed to turn the rudder. For aircraft the method can also be applied to elevator (aircraft), elevators and ailerons; all three aircraft control surfaces may also be mass balanced, chiefly to avoid Aeroelastic flutter, aerodynamic flutter. Ships A balanced rudder is a rudder in which the axis of rotation of the rudder is behind its front edge. This means that when the rudder is turned, the pressure of water caused by the ship's movement through the water acts upon the forward part to exert a force which increases the angle of deflection, so counteracting the pressure acting on the after part, which acts to reduce the angle of deflection. A degree of semi-balance is normal to avoid rudder instability i.e. the area in front of the pivot is less than that behind. This allows the rudder to be moved with less effort than is ne ...

Fin (aeronautics)
An aircraft stabilizer is an aerodynamic surface, typically including one or more movable control surfaces, that provides longitudinal (pitch) and/or directional (yaw) stability and control. A stabilizer can feature a fixed or adjustable structure on which any movable control surfaces are hinged, or it can itself be a fully movable surface such as a stabilator. Depending on the context, "stabilizer" may sometimes describe only the front part of the overall surface. In the conventional aircraft configuration, separate vertical (fin) and horizontal (tailplane) stabilizers form an empennage positioned at the tail of the aircraft. Other arrangements of the empennage, such as the V-tail configuration, feature stabilizers which contribute to a combination of longitudinal and directional stabilization and control. Longitudinal stability and control may be obtained with other wing configurations, including canard, tandem wing and tailless aircraft. Some types of aircraft are stabili ...

Elevator (aeronautics)
Elevators are flight control surfaces, usually at the rear of an aircraft, which control the aircraft's flight dynamics, pitch, and therefore the angle of attack and the lift of the wing. The elevators are usually hinged to the tailplane or horizontal stabilizer (aircraft), stabilizer. They may be the only pitch control surface present, and are sometimes located at the front of the aircraft (early airplanes and canard (aeronautics), canards) or integrated into a rear "all-moving tailplane", also called a slab elevator or stabilator. Elevator control effectiveness The elevator is a usable up and down system that controls the plane, horizontal stabilizer usually creates a ''downward'' force which balances the nose down moment (physics), moment created by the wing lift force, which typically applies at a point (the wing center of lift) situated aft of the airplane's center of gravity. The effects of drag (physics), drag and changing the engine thrust may also result in pitch mome ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
