Payen PA-22
The Payen PA-22 was a French experimental aircraft designed by Nicolas Roland Payen. The aircraft had an unconventional design: it had a set of delta wings, in front of which were a set of short conventional wings. It had a fixed front landing gear and the cockpit was further back than usual. Design and development In 1935 the prolific aircraft designer Roland Payen developed a radical tandem-wing configuration aircraft which he dubbed the "Fléchair" (Arrow). The PA 22/1R was to be powered by an early form of ramjet known as the Melot 1R engine. This design was to participate in the 1939 Coupe Deutsch de la Meurthe air race. Unfortunately the Melot engine was not able to develop the required thrust and the 1939 Coupe Deutsch de la Meurthe was cancelled due to the start of World War II.Payen PA-22 / PA-112< ...

Experimental Aircraft
An experimental aircraft is an aircraft intended for testing new aerospace technologies and design concepts. The term ''research aircraft'' or ''testbed aircraft'', by contrast, generally denotes aircraft modified to perform scientific studies, such as weather research or geophysical surveying, similar to a research vessel. United States The term "experimental aircraft" also has specific legal meaning in Australia, the United States and some other countries; usually used to refer to aircraft flown with an experimental certificate. In the United States, this also includes most homebuilt aircraft, many of which are based on conventional designs and hence are experimental only in name because of certain restrictions in operation.

Wind Tunnel
Wind tunnels are large tubes with air blowing through them which are used to replicate the interaction between air and an object flying through the air or moving along the ground. Researchers use wind tunnels to learn more about how an aircraft will fly. NASA uses wind tunnels to test scale models of aircraft and spacecraft. Some wind tunnels are large enough to contain full-size versions of vehicles. The wind tunnel moves air around an object, making it seem as if the object is flying. Most of the time, large powerful fans suck air through the tube. The object being tested is held securely inside the tunnel so that it remains stationary. The object can be an aerodynamic test object such as a cylinder or an airfoil, an individual component, a small model of the vehicle, or a full-sized vehicle. The air moving around the stationary object shows what would happen if the object was moving through the air. The motion of the air can be studied in different ways; smoke or dye can be ...

1940s French Experimental 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.

Air Enthusiast
''Air Enthusiast'' was a British, bi-monthly, aviation magazine, published by the Key Publishing group. Initially begun in 1974 as ''Air Enthusiast Quarterly'', the magazine was conceived as a historical adjunct to '' Air International'' magazine. ''Air International'' was (and still is) involved with current aviation topics and the ''Quarterly'' concerned itself with historical matters. Each issue contained 80 pages; as a result certain articles were divided and each part appeared over a number of issues. ''Air Enthusiast'' was illustrated with colour and black-and-white photos, diagrams, profiles and three-view drawings. Earlier issues featured cutaway drawings, but these were dropped. The articles provided detail for varieties of aircraft 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 ...

Payen Pa 49
The Payen Pa 49 Katy was a small Experimental aircraft, experimental France, French turbojet powered tailless aircraft, designed by Nicolas Roland Payen, and first flown in 1954. It was the first French aircraft of this kind and the smallest jet aircraft of its day. Design and development Roland Payen was a pioneer of tailless and delta winged aircraft, building two designs, a light aircraft and a fighter, before World War II, the Second World War. The Pa 49 Katy was his first post-war design. The all-wood Katy was a tailless aircraft, having no separate horizontal stabilizer, horizontal stabiliser. The wing leading edge was swept at about 55° but, unlike the classic delta with its straight trailing edge, the Katy's was swept at about 30° with each trailing edge carrying full span control surfaces, elevator (aircraft), elevators inboard and ailerons outboard. At its root, the wing merged gently into the fuselage with small air intakes for the 1.47 kN (330 lbf) Turbom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Variable-pitch Propeller (aeronautics)
In aeronautics, a variable-pitch propeller is a type of propeller (airscrew) with blades that can be rotated around their long axis to change the blade pitch. A controllable-pitch propeller is one where the pitch is controlled manually by the pilot. Alternatively, a constant-speed propeller is one where the pilot sets the desired engine speed (RPM), and the blade pitch is controlled automatically without the pilot's intervention so that the rotational speed remains constant. The device which controls the propeller pitch and thus speed is called a propeller governor or constant speed unit. Reversible propellers are those where the pitch can be set to negative values. This creates reverse thrust for braking or going backwards without the need to change the direction of shaft revolution. Some aircraft have ground-adjustable propellers, however these are not considered variable-pitch. These are typically found only on light aircraft and microlights. Purpose When an aircraft is st ...

Chalais-Meudon
Chalais-Meudon is an aeronautical research and development centre in Meudon, to the south-west of Paris. It was originally founded in 1793 in the nearby Château de Meudon and has played an important role in the development of French aviation. Balloons The story of aviation at Chalais-Meudon starts in October 1793 when the French Public Safety Committee ordered the construction of an observation balloon capable of carrying two observers. The old royal grounds at Meudon were allocated for this work, with the Château de Meudon chosen as the centre, with Nicolas-Jacques Conté as director. Two French Balloon Corps balloon companies had already been created, and the new organisation's role was to build balloons and train their pilots and operators. The first balloon, the ''Entreprenant'', was built within four months, and on 31 October 1794, the National School of Ballooning was created, with Conté as its director. Many other balloons were then built in a short period, including, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
