Aero Space Museum
The Hangar Flight Museum, formerly known as the Aero Space Museum of Calgary is a museum located south of Calgary International Airport in Calgary, Alberta, Canada. History The museum was founded in 1975 as the Aero Space Museum Association of Calgary by aviation enthusiasts and former World War II pilots. It built upon the history of an earlier private collection called the Air Museum of Canada. The museum moved to its current location in a former British Commonwealth Air Training Plan hangar in 1985. A renovation was carried out in 2016 that included replacing the roof and installing a new HVAC system. That same year, the museum changed its name to The Hangar Flight Museum. Following a seven-year restoration, the museum's Hawker Hurricane returned in 2019. Exhibits The museum has an exhibit Canadian space programs as well as an archives containing documents about aeronautics. A central War memorial stone slab and four other memorial slabs were erected by the Aircrew Associat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glider Aircraft
A glider is a fixed-wing aircraft that is supported in flight by the dynamic reaction of the air against its lifting surfaces, and whose free flight does not depend on an engine. Most gliders do not have an engine, although motor-gliders have small engines for extending their flight when necessary by sustaining the altitude (normally a sailplane relies on rising air to maintain altitude) with some being powerful enough to take off by self-launch. There are a wide variety of types differing in the construction of their wings, aerodynamic efficiency, location of the pilot, controls and intended purpose. Most exploit meteorological phenomena to maintain or gain height. Gliders are principally used for the air sports of gliding, hang gliding and paragliding. However some spacecraft have been designed to descend as gliders and in the past military gliders have been used in warfare. Some simple and familiar types of glider are toys such as paper planes and balsa wood gliders. Etym ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1950s United States Sailplanes
Year 195 ( CXCV) was a common year starting on Wednesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Scrapula and Clemens (or, less frequently, year 948 ''Ab urbe condita''). The denomination 195 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 has the Roman Senate deify the previous emperor Commodus, in an attempt to gain favor with the family of Marcus Aurelius. * King Vologases V and other eastern princes support the claims of Pescennius Niger.

Briegleb El Mirage Airfield
Victorville Army Airfield auxiliary fields were four airfields used during World War II to support the Victorville Army Airfield pilot training near Victorville, California, and Adelanto, California. After the war the Victorville Army Airfield was renamed George Air Force Base on January 13, 1948. The airfields were built in 1941 by the United States Army Air Corps just before the war. Victorville Army Airfield covered 2,200-acre in the Mojave Desert. The US Army held a groundbreaking ceremony on 12 July 1941. The base, called Victorville Army Flying School, was ready to use before the attack on Pearl Harbor on December 7, 1941. The Army built four runways in a triangle configuration, with one runway down the middle of the triangle. Seven hangars were built to support operation. On April 23, 1943, the base was renamed Victorville Army Airfield. Victorville Army Airfield With the US now in the war, many pilots were needed, the first classes started in February 1942. Ai ...

National Soaring Museum
The National Soaring Museum (NSM) is an aviation museum whose stated aim is to preserve the history of motorless flight. It is located on top of Harris Hill near Elmira, New York, United States. The NSM is the Soaring Society of America's official repository. In 1975, the SSA Board of Directors transferred the Soaring Hall of Fame to the National Soaring Museum. The museum features a large collection of vintage and historical gliders. The museum also administers the National Landmark of Soaring program to recognize people, places and events which are significant in the history of motorless aviation. History Elmira and Harris Hill have long been associated with soaring in the USA. The establishment of the nation's most prolific glider manufacturer, Schweizer Aircraft in Elmira and the holding of first 13 National Soaring Contests at the site between 1930 and 1946 guaranteed its stature as a location. During the US National Soaring Contests in the 1950s competitors and organizer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 ...

Cherokee II
The Hall Cherokee II is an American high-wing, single seat glider that was designed by Stan Hall and introduced in 1956 as plans for amateur construction.Said, Bob: ''1983 Sailplane Directory, Soaring Magazine'', pages 8-9. Soaring Society of America, November 1983. USPS 499-920 Due to its low cost and ease of construction, the Cherokee II is one of the most produced home-built gliders. Design and development The Cherokee was designed by Hall to provide homebuilders with an easy-to-construct and inexpensive aircraft that would give performance at least equal to the Schweizer SGS 1-26, which had flown two years earlier. The Cherokee structure is built from wood and covered in doped aircraft fabric covering. The fuselage features truss construction, with longerons and gussets and a fixed monowheel landing gear. The wing has two spars, with geodetic braces handling the torsion loads and is built with a fixed center section and removable outer wing panels. The wings have spoile ...

Standard Class
Competition classes in gliding, as in other sports, mainly exist to ensure fairness in competition. However the classes have not been targeted at fostering technological development as in other sports. Instead classes have arisen because of: * the popularity of certain types of glider * attempts to contain the cost of access to the sport * the need to establish a stable environment for investment decisions by both manufacturers and competitors. The FAI Gliding Commission (IGC) is the sporting body overseeing air sports at the international level so that essentially the same classes and class definitions are followed in all countries. FAI Competition Classes Seven glider classes are currently recognised by the FAI and are eligible for European and World Championships: * Open Class, places no restrictions except a limit of 850 kg to the maximum all-up mass, may be one- or two-seater e.g. JS-1C, Lange Antares 23E, Quintus, ASW 22, ASH 30, LAK-20. * Standard Class, restr ...
