ERCO Ercoupe
The ERCO Ercoupe is an American low-wing monoplane aircraft that was first flown in 1937. It was originally manufactured by the Engineering and Research Corporation (ERCO) shortly before World War II; several other manufacturers continued its production after the war. The final model, the Mooney M-10, first flew in 1968 and the last model year was 1970. It was designed to be the safest fixed-wing aircraft that aerospace engineering could provide at the time, and the type continues to enjoy a faithful following. Design and development Fred Weick In 1931, aeronautical engineer Fred Weick was assistant chief of the aeronautics division of the National Advisory Committee for Aeronautics (NACA). In 1934 he asked permission to build an aircraft based on the 1931 Stout Skycar, using fabric instead of aluminum covering, and control modifications based on NACA research. Weick and a group of co-workers designed and assembled the experimental aircraft with a group of his colleagues wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tricycle Landing Gear
Tricycle gear is a type of aircraft undercarriage, or ''landing gear'', arranged in a tricycle fashion. The tricycle arrangement has a single nose wheel in the front, and two or more main wheels slightly aft of the center of gravity. Tricycle gear aircraft are the easiest for takeoff, landing and taxiing, and consequently the configuration is the most widely used on aircraft.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', page 524. Aviation Supplies & Academics, 1997. Aviation Publishers Co. Limited, ''From the Ground Up'', page 11 (27th revised edition) History Several early aircraft had primitive tricycle gear, notably very early Antoinette planes and the Curtiss Pushers of the pre-World War I Pioneer Era of aviation. Waldo Waterman's 1929 tailless '' Whatsit'' was one of the first to have a steerable nose wheel. In 1956, Cessna introduced sprung-steel tricycle landing gear on the Cessna 172. Their marketing department described this as "Land-O-Matic" t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bubble Canopy
A bubble canopy is an aircraft canopy constructed without bracing, for the purpose of providing a wider unobstructed field of view to the pilot, often providing 360° all-round visibility. The designs of bubble canopies can drastically vary; some, such as on later versions of the F4U Corsair, are built into the upper rear fuselage, while others, like the canopy of the P-51D Mustang and most modern combat aircraft, are built flush with the fuselage, providing unobstructed rear visibility. Although experimented with as early as the First World War, the bubble canopy was introduced to widespread use during the Second World War, being used upon a number of American, British, and Japanese aircraft, commonly fighters. During the postwar era, the bubble canopy became a common feature of jet-powered fighter aircraft. Outside of combat aircraft, such canopies have also been adopted upon several helicopters and general aviation aircraft, often for roles that benefit from a high level of e ...

College Park Airport
College Park Airport is a public airport located in the City of College Park, in Prince George's County, Maryland, United States. It is the world's oldest continuously operated airport. The airport is located south of Paint Branch and Lake Artemesia, east of U.S. Route 1 and the College Park Metro/MARC station and west of Kenilworth Avenue. History College Park Airport was established in August 1909 by the United States Army Signal Corps to serve as a training location for Wilbur Wright to instruct two military officers to fly in the government's first airplane. Leased on August 25, the first airplane, a Wright Type A biplane, was uncrated and assembled on October 7. Civilian aircraft began flying from College Park Airport as early as December 1911, making it the world's oldest continuously operated airport. In 1977, the airport was added to the National Register of Historic Places. College Park Airport is home to many "firsts" in aviation, and is particularly significant f ...

Erco 415-CDX Ercoupe Owner-maintenance CF-LUN 02
Engineering and Research Corporation (ERCO) was started by Henry Berliner in 1930. Berliner was the son of Emile Berliner, who had patented numerous inventions relating to sound and acoustics, and pioneer of helicopter development with the experimental Berliner Helicopter. The younger Berliner founded ERCO to produce tools for the manufacture of metal aircraft and propellers. He founded the company in a shed at 2014 5th Street NW Washington D.C. Berliner met Fred Weick, an aeronautical engineer, who worked with National Advisory Committee for Aeronautics in NACA cowling, cowlings and propellers on a 1926 while developing the propellers for the USS Akron (ZRS-4), USS Akron. Weick also worked on an experimental aircraft that incorporated the up-to-date safety features. In 1935, the company moved to 6100 Sligo Blvd. In 1936, Weick left NACA to work for ERCO on his "safety airplane". In 1937, Berliner purchased 50 acres of land in Riverdale Park, Maryland, Riverdale, Maryland near ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tractor Configuration
In aviation, the term tractor configuration refers to an aircraft constructed in the standard configuration with its engine mounted with the propeller in front of it so that the aircraft is "pulled" through the air. Oppositely, the pusher configuration places the airscrew behind and propels the aircraft forward. Through common usage, the word "propeller" has come to mean any airscrew, whether it actually propels or pulls the plane. In the early years of powered aviation both tractor and pusher designs were common. However, by the midpoint of the First World War, interest in pushers declined and the tractor configuration dominated. Today, propeller-driven aircraft are assumed to be tractors unless it is stated otherwise. Origins The first airplane to have a "tractor" configuration was the Goupy No.2 (first flight on 11 March 1909) designed by Mario Calderara and financed by Ambroise Goupy at the French firm Blériot Aéronautique. When it was constructed, it was the fast ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Low-wing
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 ...

Spin (flight)
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 a ...

Stall (flight)
In fluid dynamics, a stall is a reduction in the lift coefficient generated by a foil as angle of attack increases.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', p. 486. Aviation Supplies & Academics, 1997. This occurs when the critical angle of attack of the foil is exceeded. The critical angle of attack is typically about 15°, but it may vary significantly depending on the fluid, foil, and Reynolds number. Stalls in fixed-wing flight are often experienced as a sudden reduction in lift as the pilot increases the wing's angle of attack and exceeds its critical angle of attack (which may be due to slowing down below stall speed in level flight). A stall does not mean that the engine(s) have stopped working, or that the aircraft has stopped moving—the effect is the same even in an unpowered glider aircraft. Vectored thrust in aircraft is used to maintain altitude or controlled flight with wings stalled by replacing lost wing lift with engine or propeller t ...

Autogiro Company Of America AC-35
The Autogiro Company of America AC-35 was an early attempt to make a roadable aircraft in the United States during the 1930s. Although it was successfully tested, it did not enter production; a 1960s attempt to revive the aircraft in a non-roadable version also failed to achieve success. Design and development The aircraft design process started in 1935. The Experimental Development Section of the Bureau of Air Commerce contracted the building of a roadable aircraft based around an PA-22 autogyro from ACA's parent company, Pitcairn Autogiro Company. The vehicle could fly at high speed in the air, and drive at up to on the ground with its rotors stowed. Six other companies were contracted to produce a roadable aircraft, but the AC-35 was the only one that met all the requirements. The AC-35 had side-by-side seating with a small baggage compartment. The fuselage was a combination of steel tube in front, and wood construction in the tail with fabric covering overall. The engine w ...

Waldo Waterman
image:Waldo Waterman.jpg, 200px, Waldo Waterman in 1920 Waldo Dean Waterman (June 16, 1894 – December 8, 1976) was an inventor and aviation pioneer from San Diego, California, San Diego, California. He developed a series of tailless swept-wing aircraft incorporating tricycle landing gear, culminating in a low-cost and simple-to-fly Flying car (aircraft), flying car. Biography Waterman built his first aircraft, a biplane hang glider, in 1909 while still in high school. He successfully flew the biplane hang glider on a slope near his home and by auto-tow. He then took on a partner to help build a powered aircraft that he entered in the first Dominguez Air Meet in January 1910. The aircraft was not completed in time for the meet. However, he began testing the aircraft on San Diego Bay, North Island. It was under-powered and required an auto-tow assist to get airborne. He flew the aircraft with some success but crashed, breaking both ankles. In 1911, Glenn Curtiss moved his winter he ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stearman-Hammond Y-1
The Stearman-Hammond Y-1 was a 1930s American utility monoplane built by the Stearman-Hammond Aircraft Corporation and evaluated by the United States Navy and the British Royal Air Force. Development In the early 1930s Dean Hammond designed the Hammond Model Y, a low-wing monoplane twin-boom pusher monoplane. Hammond cooperated with the aircraft designer Lloyd Stearman to develop the type for production. They formed the Stearman-Hammond Aircraft Corporation in 1936 to build the aircraft as the Stearman-Hammond Y-1. The first aircraft was powered by a 125 hp (93 kW) Menasco C-4 piston engine driving a pusher propeller. The performance was not impressive so it was re-engined with a 150 hp (112 kW) Menasco C-4S and re-named the Y-1S. Although designed to be easy to fly the high price meant only 20 aircraft were produced. The aircraft had no rudder as such, the tailplane fins being adjustable but fixed in flight. Turning was by differential aileron and elevator al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
