Facetmobile
The Wainfan FMX-4 Facetmobile is an American homebuilt aircraft designed by Barnaby Wainfan, a Northrop Grumman aerodynamicist and homebuilt aircraft engineer. While only one Facetmobile prototype was produced, it has become well known due to its unique nature. The aircraft is unusual in that it is a lifting body – the whole aircraft acts as a low aspect ratio wing: a flat, angular lifting shape, unlike traditional aircraft which use distinct lift-generating wings attached to a non-lifting fuselage.Barnaby and Lynn Wainfan's Facetmobile page accessed October 24, 2006 Also notably the aircraft's shape is formed of a series of 11 flat surfaces, somewhat similar to the body of the |
Lifting Bodies
A lifting body is a fixed-wing aircraft or spacecraft configuration in which the body itself produces lift. In contrast to a flying wing, which is a wing with minimal or no conventional fuselage, a lifting body can be thought of as a fuselage with little or no conventional wing. Whereas a flying wing seeks to maximize cruise efficiency at subsonic speeds by eliminating non-lifting surfaces, lifting bodies generally minimize the drag and structure of a wing for subsonic, supersonic and hypersonic flight, or spacecraft re-entry. All of these flight regimes pose challenges for proper flight safety. Lifting bodies were a major area of research in the 1960s and 70s as a means to build a small and lightweight crewed spacecraft. The US built a number of lifting body rocket planes to test the concept, as well as several rocket-launched re-entry vehicles that were tested over the Pacific. Interest waned as the US Air Force lost interest in the crewed mission, and major development en ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rotax 503
The Rotax 503 is a , inline 2-cylinder, two-stroke aircraft engine, built by BRP-Rotax GmbH & Co. KG of Austria for use in ultralight aircraft.Raisner, William: ''LEAF catlog'', pages 6-105. Leading Edge Airfoils, 1995. As of 2011 the Rotax 503 is no longer in production. Design and development The Rotax 503 is piston ported with air-cooled cylinders and heads, utilizing either an engine driven fan and cowl, or free air cooling. Lubrication is either by use of pre-mixed fuel and oil or oil injection from an externally mounted oil tank. The 503 has dual independent breakerless, magneto capacitor-discharge ignition (CDI) systems. It can be equipped with either one or two piston-type carburetors. It uses a manifold-driven pneumatic fuel pump to provide fuel pressure. An optional High Altitude Compensation kit is available. The engine's propeller drive is via a Rotax type B, C, or E style gearbox. The standard engine includes a muffler exhaust system with an extra after-muf ...

Verhees D-Plane 1
The Verhees D-Plane 1 is a Belgian homebuilt flying wing, designed by Verhees Engineering and supplied as plans for amateur construction.Bayerl, Robby; Martin Berkemeier; et al: ''World Directory of Leisure Aviation 2011-12'', page 125. WDLA UK, Lancaster UK, 2011. Design and development The D-Plane 1 features a cantilever mid-wing, a single-seat enclosed cockpit, semi-retractable tandem landing gear with small tail and wingtip wheels and a single engine in tractor configuration. Control surfaces include an elevon at the trailing edge of each wing and a conventional vertical stabilizer with a rudder. The aircraft is made chiefly from sheet aluminum. Its very low aspect ratio span delta wing has an area of . The single nose-mounted wheel retracts while the tail and wing tip wheels are fixed. The recommended engine is the 1.6 litre displacement Subaru EA71 four-stroke flat-4 (boxer) automotive conversion powerplant. By 2011 only the prototype D-Plane 1 had flown, but dev ...

F-117 Nighthawk
The Lockheed F-117 Nighthawk is a retired American single-seat, twin-engine stealth attack aircraft developed by Lockheed's secretive Skunk Works division and operated by the United States Air Force (USAF). It was the first operational aircraft to be designed with stealth technology. The F-117 was based on the ''Have Blue'' technology demonstrator. The Nighthawk's maiden flight took place in 1981 at Groom Lake, Nevada, and the aircraft achieved initial operating capability status in 1983. The aircraft was shrouded in secrecy until it was revealed to the public in 1988. Of the 64 F-117s built, 59 were production versions, with the other five being prototypes. The F-117 was widely publicized for its role in the Gulf War of 1991. Although it was commonly referred to as the "Stealth Fighter", it was strictly an attack aircraft. F-117s took part in the conflict in Yugoslavia, where one was shot down by a surface-to-air missile (SAM) in 1999. The U.S. Air Force retired the F-117 ...

Dyke Delta
The Dyke Delta JD-2 is an American homebuilt aircraft designed in the United States in the 1960s and marketed for amateur construction. It is a monoplane with retractable tricycle undercarriage and seating for four. The wings can be folded for towing or storage and hinge upwards to lie flat above the fuselage, one atop the other. Construction is of SAE 4130 grade steel tube framework with fiberglass and fabric skins. In its standard configuration, the aircraft is a true double-delta with no horizontal stabilizer; however, a small T-tail is an option for trimming variants with higher-power engines. Since the mid-1960s, designer John Dyke has sold full construction plans and three-view drawings for the aircraft to homebuilders and is still selling them today. No kits were ever marketed. Over fifty examples have been completed. Development Designer John Dyke said his inspiration for the aircraft came from Alexander Lippisch's delta designs, specifically the LP-6 glider and later th ...

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 ...

Homebuilt Aircraft
Homebuilt aircraft, also known as amateur-built aircraft or kit planes, are constructed by persons for whom this is not a professional activity. These aircraft may be constructed from "scratch", from plans, or from assembly kits.Armstrong, Kenneth: ''Choosing Your Homebuilt - the one you will finish and fly! Second Edition'', pp. 39–52. Butterfield Press, 1993. Peter M Bowers: ''Guide to Homebuilts - Ninth Edition''. TAB Books, Blue Ridge Summit PA, 1984. Overview In the United States, Brazil, Australia, New Zealand and South Africa, homebuilt aircraft may be licensed Experimental under FAA or similar local regulations. With some limitations, the builder(s) of the aircraft must have done it for their own education and recreation rather than for profit. In the U.S., the primary builder can also apply for a repairman's certificate for that airframe. The repairman's certificate allows the holder to perform and sign off on most of the maintenance, repairs, and inspections themsel ...

Elevons
Elevons or tailerons are aircraft control surfaces that combine the functions of the elevator (used for pitch control) and the aileron (used for roll control), hence the name. They are frequently used on tailless aircraft such as flying wings. An elevon that is not part of the main wing, but instead is a separate tail surface, is a stabilator (but stabilators are also used for pitch control only, with no roll function, as on the Piper Cherokee series of aircraft). Elevons are installed on each side of the aircraft at the trailing edge of the wing. When moved in the same direction (up or down) they will cause a pitching force (nose up or nose down) to be applied to the airframe. When moved differentially, (one up, one down) they will cause a rolling force to be applied. These forces may be applied simultaneously by appropriate positioning of the elevons e.g. one wing's elevons completely down and the other wing's elevons partly down. An aircraft with elevons is controlled as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
