DFS 230 F
The DFS 230F was a military assault glider designed and built in Germany, by Gotha during World War II, to succeed the smaller DFS 230 which it was only related to by name. Design and development After initial operations using the DFS 230, it became obvious to the Wehrmacht that a larger more capable assault glider would be desirable. The DFS 230 F was designed to fulfil that need, but in an atmosphere of political intransigence. The RLM (Reichsluftfahrtministerium - German Air Ministry), issued a directive in 1941 that no effort was to be spent designing a replacement for the rather dated DFS 230 assault glider, in its weight class. Ing. Hünerjäger of Gothaer Waggonfabrik (Gotha) believed that a great improvement on the DFS 230 could be achieved with an aircraft of similar dimensions designing what was named the DFS 230 V7 despite the ban. Gotha named their new design's prototype DFS 230 V7, production aircraft were to be designated DFS 230F-1, to deflect criticism for ign ...

WikiProject Aircraft
A WikiProject, or Wikiproject, is a Wikimedia movement affinity group for contributors with shared goals. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within sister projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by '' Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000". On Wikipedia Some Wikipedia WikiProjects are substantial enough to engage in cooperative activities with outside organizations relevant to the field at issue. For e ...

Flap (aeronautics)
A flap is a high-lift device used to reduce the stall (flight), stalling speed of an aircraft wing at a given weight. Flaps are usually mounted on the wing trailing edges of a fixed-wing aircraft. Flaps are used to reduce the take-off distance and the landing distance. Flaps also cause an increase in Drag (physics), drag so they are retracted when not needed. The flaps installed on most aircraft are partial-span flaps; spanwise from near the wing root to the inboard end of the ailerons. When partial-span flaps are extended they alter the spanwise lift distribution on the wing by causing the inboard half of the wing to supply an increased proportion of the lift, and the outboard half to supply a reduced proportion of the lift. Reducing the proportion of the lift supplied by the outboard half of the wing is accompanied by a reduction in the angle of attack on the outboard half. This is beneficial because it increases the margin above the Stall (fluid dynamics), stall of the outboa ... [...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] |

Vehicles Introduced In 1943
A vehicle (from la, vehiculum) is a machine that transports people or cargo. Vehicles include wagons, bicycles, motor vehicles (motorcycles, cars, trucks, buses, mobility scooters for disabled people), railed vehicles (trains, trams), watercraft (ships, boats, underwater vehicles), amphibious vehicles (screw-propelled vehicles, hovercraft), aircraft (airplanes, helicopters, aerostats) and spacecraft.Halsey, William D. (Editorial Director): ''MacMillan Contemporary Dictionary'', page 1106. Macmillan Publishers, MacMillan Publishing, 1979. Land vehicles are classified broadly by what is used to apply steering and drive force (physics), forces against the ground: wheeled vehicle, wheeled, tracked vehicle, tracked, railed vehicle, railed or Ski#Use on vehicles, skied. ISO 3833-1977 is the standard, also internationally used in legislation, for road vehicles types, terms and definitions.

General Aircraft Hotspur
The General Aircraft GAL.48 Hotspur was a military glider designed and built by the British company General Aircraft Limited, General Aircraft Ltd during World War II. When the British airborne forces, airborne establishment was formed in 1940 by order of Prime Minister of the United Kingdom, Prime Minister Winston Churchill, it was decided that gliders would be used to transport airborne troops into battle. General Aircraft Ltd were given a contract by the Ministry of Aircraft Production in June 1940 to design and produce an initial glider for use by the airborne establishment, which resulted in the Hotspur. Conceived as an "assault" glider which necessitated a compact design and no more than eight troops carried, tactical philosophy soon favoured larger numbers of troops being sent into battle aboard gliders. Due to this, the Hotspur was mainly relegated to training where it did excel and it became the basic trainer for the glider schools that were formed.Munson 1972, p. 199. ...

Fallschirmjäger
The ''Fallschirmjäger'' () were the paratrooper branch of the German Luftwaffe before and during World War II. They were the first German paratroopers to be committed in large-scale airborne operations. Throughout World War II, the commander of the branch was Kurt Student. Pre-war history During the interwar years the rapid development of aircraft and aviation technology drew the attention of imaginative military planners. The idea of aerially inserting a large body of troops inside enemy territory was first proposed during World War I by Brigadier General Billy Mitchell, commander of the U.S. Army Air Corps in France.Ailsby, Christopher: ''Hitler's Sky Warriors: German Paratroopers in Action, 1939-1945'', page 12. Spellmount Limited, 2000. However, the Allied High Command was forced to abandon the idea, as it was unprepared for such an undertaking, both logistically and in materiel. Among the first to recognize the potential of airborne forces were Italy and the Soviet Union ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Landing Gear
Landing gear is the undercarriage of an aircraft or spacecraft that is used for takeoff or landing. For aircraft it is generally needed for both. It was also formerly called ''alighting gear'' by some manufacturers, such as the Glenn L. Martin Company. For aircraft, Stinton makes the terminology distinction ''undercarriage (British) = landing gear (US)''. For aircraft, the landing gear supports the craft when it is not flying, allowing it to take off, land, and taxi without damage. Wheeled landing gear is the most common, with skis or floats needed to operate from snow/ice/water and skids for vertical operation on land. Faster aircraft have retractable undercarriages, which fold away during flight to reduce drag. Some unusual landing gear have been evaluated experimentally. These include: no landing gear (to save weight), made possible by operating from a catapult cradle and flexible landing deck: air cushion (to enable operation over a wide range of ground obstacles and wat ...

Spoiler (aeronautics)
In aeronautics, a spoiler (sometimes called a lift spoiler or lift dumper) is a device which intentionally reduces the lift (force), lift component of an airfoil in a controlled way. Most often, spoilers are plates on the top surface of a wing that can be extended upward into the airflow to ''spoil'' the streamline flow. By so doing, the spoiler creates a controlled Stall (flight), stall over the portion of the wing behind it, greatly reducing the lift of that wing section. Spoilers differ from air brake (aeronautics), airbrakes in that airbrakes are designed to increase drag without disrupting the lift distribution across the wing span, while spoilers disrupt the lift distribution as well as increasing drag. Spoilers fall into two categories: those that are deployed at controlled angles during flight to increase descent rate or control roll, and those that are fully deployed immediately on landing to greatly reduce lift ("lift dumpers") and increase drag.
