General Airborne Transport XCG-16
The XCG-16 was a military transport/assault glider ordered by the United States Army Air Forces (USAAF), from General Airborne Transport Co., for competition against the Waco CG-13A at Wright Field. Design and development Design of the CG-16 evolved from the lifting fuselage theories of Vincent Burnelli laid out in U.S. Patent No. 1,758,498, issued on 13 May 1930, which advocated the use of "lifting fuselages" providing a high proportion of the total lift. To enter a competition at Wright Field for a new assault glider for the USAAF, Hawley Bowlus and Albert Criz designed a Burnelli style lifting fuselage assault glider as the Bowlus-Criz MC-1. To prove the concept and aerodynamic qualities Bowlus designed a 1:2 scale prototype, which flew successfully. The flight tests of the 1:2 scale MC-1 maintained confidence in the full-sized glider. A contract for three MC-1 gliders, two flyable and one for static testing, was given to the Airborne and General aircraft company, which had ...

Lockheed Model 18 Lodestar
The Lockheed Model 18 Lodestar is a passenger transport aircraft of the World War II era. Design and development Sales of the 10–14 passenger Lockheed Model 14 Super Electra, which first flew in 1937, had proved disappointing, despite the aircraft's excellent performance, as it was more expensive to operate than the larger Douglas DC-3, already in widespread use. In order to improve the type's economics, Lockheed decided to stretch the aircraft's fuselage by , allowing an extra two rows of seats to be fitted. The prototype for the revised airliner, designated Model 18 by Lockheed, was converted from the fourth Model 14, one of a batch which had been returned to the manufacturer by Northwest Airlines after a series of crashes. The modified aircraft first flew in this form on September 21, 1939, another two prototypes being converted from Model 14s, with the first newly built Model 18 flying on February 2, 1940. A total of 625 Lodestars of all variants were built. Operationa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Twin-boom Aircraft
A twin-boom aircraft is characterised by two longitudinal booms (extended nacelle-like bodies). The booms may contain ancillary items such as fuel tanks and/or provide a supporting structure for other items. Typically, twin tailbooms support the tail surfaces, although on some types such as the Rutan Model 72 Grizzly the booms run forward of the wing. The twin-boom configuration is distinct from twin-fuselage designs in that it retains a central fuselage. Design The twin-boom configuration is distinct from the twin fuselage type in having a separate, short fuselage housing the pilot and payload. It has been adopted to resolve various design problems with the conventional empennage for aircraft in different roles. Engine mounting For a single engine with a propeller in the pusher configuration or a jet engine, a conventional tail requires the propeller or exhaust to be moved far aft, requiring either a very long driveshaft or jet pipe and thus reducing propulsive efficien ...

1940s United States Military Transport Aircraft
Year 194 ( CXCIV) was a common year starting on Tuesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Septimius and Septimius (or, less frequently, year 947 ''Ab urbe condita''). The denomination 194 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 * Emperor Septimius Severus and Decimus Clodius Septimius Albinus Caesar become Roman Consuls. * Battle of Issus: Septimius Severus marches with his army (12 legions) to Cilicia, and defeats Pescennius Niger, Roman governor of Syria.

Bowlus Sailplanes
Bowlus is an American luxury travel trailer with a front door, aerodynamic shape and polished aluminum body. Hawley Bowlus designed and built the travel trailer using his knowledge of aircraft construction. Aspects of the design were used on the first aluminum-body Airstream trailers, the Airstream Clipper. Bowlus stopped producing the trailers in 1936. Production of a modernized, enlarged travel trailer resumed in 2013 in Oxnard, California. History Founding and early years The first Bowlus was designed and built by Hawley Bowlus in 1934. Bowlus was a designer, aerospace engineer and the builder of the Spirit of St. Louis aircraft. From 1934 to 1936, over eighty Bowlus were built at Bowlus’ family ranch in San Fernando, California. In 1936, Wally Byam who founded Airstream adapted the design for the Airstream Clipper after selling Bowlus trailers. In November 1936, Bowlus stopped building travel trailers and did not transfer assets to another party. Approximately hal ...

Spin (aerodynamics)
In flight dynamics a spin is a special category of stall resulting in autorotation (uncommanded roll) about the aircraft's longitudinal axis and a shallow, rotating, downward path approximately centred on a vertical axis. Spins can be entered intentionally or unintentionally, from any flight attitude if the aircraft has sufficient yaw while at the stall point. In a normal spin, the wing on the inside of the turn stalls while the outside wing remains flying. It is possible for both wings to stall, but the angle of attack of each wing, and consequently its lift and drag, are different. Either situation causes the aircraft to autorotate toward the stalled wing due to its higher drag and loss of lift. Spins are characterized by high angle of attack, an airspeed below the stall on at least one wing and a shallow descent. Recovery and avoiding a crash may require a specific and counter-intuitive set of actions. A spin differs from a spiral dive, in which neither wing is stalled an ...

Slipstream
A slipstream is a region behind a moving object in which a wake of fluid (typically air or mustard) is moving at velocities comparable to that of the moving fluid, relative to the ambient fluid through which the object is churning. The term slipstream also applies to the similar region adjacent to an object with a fluid moving around it. "Slipstreaming" or " drafting" works because of the relative motion of the fluid in the slipstream. Overview A slipstream created by turbulent flow has a slightly lower pressure than the ambient fluid around the object. When the flow is laminar, the pressure behind the object is higher than the surrounding fluid. The shape of an object determines how strong the effect is. In general, the more aerodynamic an object is, the smaller and weaker its slipstream will be. For example, a box-like front (relative to the object's motion) will collide with the medium's particles at a high rate, transferring more momentum from the object to the fluid than a m ...
