Ultralight Trikes
An ultralight trike is a type of powered hang glider where flight control is by weight-shift. These aircraft have a fabric flex-wing from which is suspended a tricycle fuselage pod driven by a pusher propeller. The pod accommodates either a solo pilot, or a pilot and a single passenger. Trikes grant affordable, accessible, and exciting flying, and have been popular since the 1980s. Trikes are classified as microlights in Europe, and as light-sport aircraft in the United States. The aircraft are also known by other names, including 2-axis microlights, flex-wing trikes, microlight trikes, deltatrikes or motorized deltaplanes. In the United States, they are formally recognized by the Federal Aviation Administration (FAA) as weight-shift-control aircraft. History ] The history of the trike is traced back to the invention of Francis Rogallo's flexible wing and subsequent development by the Paresev engineering team's innovations and then others. On 1948, engineer Franci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Francis Rogallo
Francis Melvin Rogallo (January 27, 1912 – September 1, 2009) was an American aeronautical engineer inventor born in Sanger, California, U.S. Together with his wife, he is credited with the invention of the Rogallo wing, or "flexible wing", a precursor to the modern hang glider and paraglider. His patents were ranged over mechanical utility patents and ornamental design patents for wing controls, airfoils, target kite, flexible wing, and advanced configurations for flexible wing vehicles. Career Francis Rogallo earned an aeronautical engineering degree at Stanford University in 1935. Since 1936, Rogallo worked for the National Advisory Committee for Aeronautics (NACA) as an aeronautics project engineer at the wind tunnels. During 1948, he and his wife, Gertrude Rogallo, invented and patented a self-inflating flexible kite. They called this kite the "flexible wing". Rogallo had originally invented the wing with the idea to create an aircraft which would be simple enough ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kite
A kite is a tethered heavier than air flight, heavier-than-air or lighter-than-air craft with wing surfaces that react against the air to create Lift (force), lift and Drag (physics), drag forces. A kite consists of wings, tethers and anchors. Kites often have a bridle and tail to guide the face of the kite so the wind can lift it. Some kite designs don’t need a bridle; box kites can have a single attachment point. A kite may have fixed or moving anchors that can balance the kite. The name is derived from kite (bird), kite, the hovering bird of prey. The Lift (force), lift that sustains the kite in flight is generated when air moves around the kite's surface, producing low pressure above and high pressure below the wings. The interaction with the wind also generates horizontal Drag (physics), drag along the direction of the wind. The resultant force vector from the lift and drag force components is opposed by the tension of one or more of the rope, lines or tethers to which t ...

Airfoil
An airfoil (American English) or aerofoil (British English) is the cross-sectional shape of an object whose motion through a gas is capable of generating significant lift, such as a wing, a sail, or the blades of propeller, rotor, or turbine. A solid body moving through a fluid produces an aerodynamic force. The component of this force perpendicular to the relative freestream velocity is called lift. The component parallel to the relative freestream velocity is called drag. An airfoil is a streamlined shape that is capable of generating significantly more lift than drag. Airfoils can be designed for use at different speeds by modifying their geometry: those for subsonic flight generally have a rounded leading edge, while those designed for supersonic flight tend to be slimmer with a sharp leading edge. All have a sharp trailing edge. Foils of similar function designed with water as the working fluid are called hydrofoils. The lift on an airfoil is primarily the result o ...

Airframe
The mechanical structure of an aircraft is known as the airframe. This structure is typically considered to include the fuselage, undercarriage, empennage and wings, and excludes the propulsion system. Airframe design is a field of aerospace engineering that combines aerodynamics, materials technology and manufacturing methods with a focus on weight, strength and aerodynamic drag, as well as reliability and cost.Michael C. Y. Niu (1988). ''Airframe Structural Design''. Conmilit Press LTD. History Modern airframe history began in the United States when a 1903 wood biplane made by Orville and Wilbur Wright showed the potential of fixed-wing designs. In 1912 the Deperdussin Monocoque pioneered the light, strong and streamlined monocoque fuselage formed of thin plywood layers over a circular frame, achieving . First World War Many early developments were spurred by military needs during World War I. Well known aircraft from that era include the Dutch designer Anth ...

Barry Hill Palmer
Barry Hill Palmer (born November 10, 1937) is an American aeronautical engineer (UC Berkeley, 1961), inventor, builder and pilot of the first hang glider based on the Rogallo wing or ''flexible wing''. Palmer also designed, built and flew the first weight-shift ultralight trike aircraft. Inventor of the first Flexible Wing hang glider On August 1961 Barry Palmer first saw a photo of the Rogallo wing mounted on the Fleep experimental aircraft published in the Aviation Week magazine and became interested in this flexible wing because of its light weight and simplicity. In October 1961 he completed construction and flew the first flexible wing hang glider; this took place near Latrobe, east of Sacramento, California. He used polyethylene sheet, aluminum tubing and no wires for construction as he did fear kinking during assembly and transport. Most flights were performed with just a set of inclined parallel bars that split his weight between his underarms and hands to experiment with ...

Ryan XV-8
The Ryan XV-8 Flexible Wing Aerial Utility Vehicle (nicknamed Fleep, short for "Flying Jeep") was an improved version of the Flex-Wing. Both aircraft were built by Ryan Aeronautical Company in collaboration with NASA for the United States Air Force and the United States Army and tested in 1961 as a STOL patrol, reconnaissance, and light utility aircraft to transport people or freight when a more specialized aircraft is not required or available. Design and development The Fleep began as the Flex-Wing. The Flex-Wing had four-wheel landing gear, a smaller nose section behind which the pilot sat, and a single vertical tail/rudder. The Fleep had tricycle landing gear, a larger nose section and a V tail/rudder. The wing was a fabric delta-shaped Rogallo wing The Rogallo wing is a flexible type of wing. In 1948, Francis Rogallo, a NASA engineer, and his wife Gertrude Rogallo, invented a self-inflating flexible wing they called the Parawing, also known after them as the "Rogall ...

Apollo 13
Apollo 13 (April 1117, 1970) was the seventh crewed mission in the Apollo space program and the third meant to land on the Moon. The craft was launched from Kennedy Space Center on April 11, 1970, but the lunar landing was aborted after an oxygen tank in the service module (SM) failed two days into the mission. The crew instead looped around the Moon and returned safely to Earth on April 17. The mission was commanded by Jim Lovell, with Jack Swigert as command module (CM) pilot and Fred Haise as Lunar Module (LM) pilot. Swigert was a late replacement for Ken Mattingly, who was grounded after exposure to rubella. A routine stir of an oxygen tank ignited damaged wire insulation inside it, causing an explosion that vented the contents of both of the SM's oxygen tanks to space. Without oxygen, needed for breathing and for generating electric power, the SM's propulsion and life support systems could not operate. The CM's systems had to be shut down to conserve its ...

Staged Combustion Cycle (rocket)
The staged combustion cycle (sometimes known as topping cycle, preburner cycle, or closed cycle) is a Liquid-propellant rocket#Engine cycles, power cycle of a bipropellant rocket Rocket engine, engine. In the staged combustion cycle, propellant flows through multiple Rocket engine#Combustion chamber, combustion chambers, and is thus combustion, combusted in stages. The main advantage relative to other rocket engine power cycles is high fuel efficiency, measured through specific impulse, while its main disadvantage is reliability engineering, engineering complexity. Typically, propellant flows through two kinds of combustion chambers; the first called preburner and the second called main combustion chamber. In the preburner, a small portion of propellant, usually fuel-rich, is partly combusted, and the increasing volume flow is used to drive the turbopumps that feed the engine with propellant. The gas is then injected into the main combustion chamber and combusted completely with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
