X-57
The NASA X-57 Maxwell is an experimental aircraft being developed by NASA, intended to demonstrate technology to reduce fuel use, emissions, and noise. The first flight of the X-57 is scheduled to take place in 2023. Development The experiment involves replacing the wings on a twin-engined Italian-built Tecnam P2006T (a conventional four-seater light aircraft) with distributed electric propulsion (DEP) wings each containing electrically driven propellers. Test flights were initially planned to commence in 2017. The first test phase uses an 18-engine truck-mounted wing. The second phase will install the cruise propellers and motors on a standard P2006T for ground- and flight-test experience. Phase 3 tests will involve the high-lift DEP wing and demonstrate increased high-speed cruise efficiency. The leading-edge nacelles will be fitted, but the high-lift propellers, motors and controllers will not be installed. Phase 4 adds the DEP motors and folding propellers to demonstrate l ...

NASA
The National Aeronautics and Space Administration (NASA ) is an independent agency of the US federal government responsible for the civil space program, aeronautics research, and space research. NASA was established in 1958, succeeding the National Advisory Committee for Aeronautics (NACA), to give the U.S. space development effort a distinctly civilian orientation, emphasizing peaceful applications in space science. NASA has since led most American space exploration, including Project Mercury, Project Gemini, the 1968-1972 Apollo Moon landing missions, the Skylab space station, and the Space Shuttle. NASA supports the International Space Station and oversees the development of the Orion spacecraft and the Space Launch System for the crewed lunar Artemis program, Commercial Crew spacecraft, and the planned Lunar Gateway space station. The agency is also responsible for the Launch Services Program, which provides oversight of launch operations and countdown management f ...

Its stabilator is attached to the fuselage, mostly aft of the vertical fin (the stabilator is a single unit with a cutout in its leading edge where it mounts to the tailcone). The nosewheel of the tricycle landing gear retracts into the nose cone; the trailing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Distributed Electric Propulsion
In aeronautics, Distributed propulsion is an arrangement in which the propulsive and related air flows are distributed over the aerodynamic surfaces of an aircraft. The purpose is to improve the craft's aerodynamic, propulsive and/or structural efficiency over an equivalent conventional design. Anticipated benefits include improved fuel efficiency, emissions, noise, landing field length and handling. Distributed propulsion may be accomplished by spanwise distribution of partially or fully embedded multiple small engines or fans along the wing. Alternatively, it may involve ducting exhaust gases along the wing's entire trailing edge. Design principles Definition Distributed propulsion on an aircraft is typically characterised not only by the distributed nature of the propulsive thrust but also by utilisation of the effect this has on the aircraft aerodynamics.Epstein, A. H. (2007"Distributed Propulsion: New Opportunities For An Old Concept" MIT. (retrieved 16 June 2022). The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electric Aircraft
An electric aircraft is an aircraft powered by electricity. Electric aircraft are seen as a way to reduce the environmental effects of aviation, providing zero emissions and quieter flights. Electricity may be supplied by a variety of methods, the most common being batteries. Most have electric motors driving propellers or turbines. Crewed flights in an electrically powered airship go back to the 19th century, and to 1917 for a tethered helicopter. Electrically powered model aircraft have been flown at least since the 1970s, preceding the small unmanned aerial vehicles (UAV) or drones used today. Small UAS could be used for parcel deliveries, and larger ones for long-endurance applications: aerial imagery, surveillance, telecommunications. The first crewed free flight by an electrically powered aeroplane, the MB-E1, was made in 1973, and most crewed electric aircraft today are still only experimental prototypes. Between 2015 and 2016, Solar Impulse 2 completed a circ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
X-plane
The X-planes are a series of experimental United States aircraft and rockets, used to test and evaluate new technologies and aerodynamic concepts. They have an X designator within the US system of aircraft designations, which denotes the experimental research mission. Not all US experimental aircraft have been designated as X-planes; some received US Navy designations before 1962, while others have been known only by manufacturers' designations, non-'X'-series designations, or classified codenames. This list only includes the designated X-planes. History The X-planes concept officially came into being in 1944, as a joint programme between the National Advisory Committee for Aeronautics (NACA), the US Navy (USN) and the US Army Air Force (USAAF), in order to pursue research into high-speed aircraft. NACA later became the National Aeronautics and Space Administration (NASA) and the USAAF became the United States Air Force (USAF). Other organizations such as the Defence Advanced ...

Transformative Aeronautics Concepts
In United States copyright law, transformative use or transformation is a type of fair use that builds on a copyrighted work in a different manner or for a different purpose from the original, and thus does not infringe its holder's copyright. Transformation is an important issue in deciding whether a use meets the first factor of the fair-use test, and is generally critical for determining whether a use is in fact fair, although no one factor is dispositive. Transformativeness is a characteristic of such derivative works that makes them transcend, or place in a new light, the underlying works on which they are based. In computer- and Internet-related works, the transformative characteristic of the later work is often that it provides the public with a benefit not previously available to it, which would otherwise remain unavailable. Such transformativeness weighs heavily in a fair use analysis and may excuse what seems a clear copyright infringement from liability. In United Stat ...

Experimental Aircraft
An experimental aircraft is an aircraft intended for testing new aerospace technologies and design concepts. The term ''research aircraft'' or ''testbed aircraft'', by contrast, generally denotes aircraft modified to perform scientific studies, such as weather research or geophysical surveying, similar to a research vessel. United States The term "experimental aircraft" also has specific legal meaning in Australia, the United States and some other countries; usually used to refer to aircraft flown with an experimental certificate. In the United States, this also includes most homebuilt aircraft, many of which are based on conventional designs and hence are experimental only in name because of certain restrictions in operation.
