EVTOL
An electric vertical take-off and landing (eVTOL) aircraft is a variety of VTOL (vertical take-off and landing) aircraft that uses electric power to hover, take off, and land vertically. This technology came about thanks to major advances in electric propulsion (motors, batteries, fuel cells, electronic controllers) and the growing need for new vehicles for urban air mobility (air taxi). Examples are being developed by aircraft companies such as Boeing, Airbus, Embraer, Honda, Toyota, Hyundai, Overair, and NASA. History The concept of eVTOL aircraft emerged in 2009 when a video of the NASA Puffin eVTOL concept went viral on November 11th 2009 showcasing a single person concept rendering of the technology, and concept in flight. Following this, the first Puffin paper at the VFS Specialists Conference on Aeromechanics, on January 9th 2010. This concept utilized a new technology developed at NASA called Distributed Electric Propulsion (DEP). Additional Puffin papers were pu ...

Boeing Passenger Air Vehicle
The Boeing Passenger Air Vehicle (PAV) is an American autonomous personal air vehicle prototype developed by the Boeing NeXt division of Boeing with the assistance of Aurora Flight Sciences. Development Boeing subsidiary Aurora Flight Sciences designed an electric VTOL prototype, developing it to prototype by 2019. First, a model 1:10 was used to test the concept; it was flown with and without a fuselage. Further flight tests, with a 1:4 scale concept aircraft, were also conducted by Aurora. The PAV first flew on January 22, 2019, in Manassas, Virginia, hovering before further tests and a transition to forward flight. By September 2020, Boeing was to close its Boeing NeXt division, in response to financial losses in the wake of the 737 MAX groundings and the impact of the COVID-19 pandemic on aviation. Design The three-surface aircraft has twin booms each supporting four lift rotors slightly angled alternatively outward and inwards, a pusher propeller and the rear wi ...

Airbus A³ Vahana
The Airbus Vahana (Sanskrit: ''Vāhana'', or Vahanam literally means "vehicle") was an electric-powered eight-propeller VTOL personal air vehicle prototype financed by A³ (pronounced "A-cubed"), by Airbus and Airbus Urban Mobility. The Vahana project started in 2016 as one of the first projects at A³, the advanced projects and partnerships outpost of Airbus Group in Silicon Valley. Airbus "envision Vahana being used by everyday commuters as a cost-comparable replacement for short-range urban transportation like cars or trains". It was planned to be a part of urban air mobility. The project was finished in December 2019. Development The convertiplane aircraft design, funded by the European aircraft manufacturer Airbus, called Vahana (Sanskrit: "vehicle"), started in 2016. It was being developed at A³ (A-cubed), the expanded project and partnership outpost of Airbus in Silicon Valley. Airbus said "Our work on this demonstrator confirms our belief that fully autonomous veh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
VTOL
A vertical take-off and landing (VTOL) aircraft is one that can take off and land vertically without relying on a runway. This classification can include a variety of types of aircraft including helicopters as well as thrust-vectoring fixed-wing aircraft and other hybrid aircraft with powered rotors such as cyclogyros/cyclocopters and gyrodynes. Some VTOL aircraft can operate in other modes as well, such as CTOL (conventional take-off & landing), STOL (short take-off & landing), or STOVL (short take-off & vertical landing). Others, such as some helicopters, can only operate as VTOL, due to the aircraft lacking landing gear that can handle taxiing. VTOL is a subset of V/STOL (vertical or short take-off & landing). Some lighter-than-air aircraft also qualify as VTOL aircraft, as they can hover, takeoff and land with vertical approach/departure profiles. Electric vertical takeoff and landing aircraft, or eVTOLs, are being developed along with more autonomous flight control ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

NAS is part of the National Academies of Sciences, Engineering, and Medicine, along with the National Academy of Engineering (NAE) and the National Academy of Medicine (NAM). As a national academy, new members of the organization are elected annually by current members, based on their distinguished and continuing achievements in original research. Election to the National Academy is one of the highest honors in the scientific field. Members of the National Academy of Sciences serve ''pro bono'' as "advisers to the nation" on science, engineering, and medicine. The group holds a congressional charter under Title 36 of the United States Code. Founded in 1863 as a result of an Act of Congress that was approved by Abraham Lincoln, the NAS is charged with "providing independent, objective advice to the nation on matters related to science and technology. ... to provide scien ...

Aramid
Aramid fibers, short for aromatic polyamide, are a class of heat-resistant and strong synthetic fibers. They are used in aerospace and military applications, for ballistic-rated body armor fabric and ballistic composites, in marine cordage, marine hull reinforcement, and as an asbestos substitute. The chain molecules in the fibers are highly oriented along the fiber axis. As a result, a higher proportion of the chemical bond contributes more to fiber strength than in many other synthetic fibers. Aramids have a very high melting point (>500 °C). Common aramid brand names include Kevlar, Nomex, and Twaron. Terminology and chemical structure ''Aramid'' is a shortened form of aromatic polyamide. The term was introduced in 1972, accepted in 1974 by the Federal Trade Commission of the USA as the name of a generic category of fiber distinct from nylon, and adopted by the International Standards Organisation in 1977. Aromatic in the name refers to the presence of aromatic r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Startup Company
A startup or start-up is a company or project undertaken by an entrepreneur to seek, develop, and validate a scalable business model. While entrepreneurship refers to all new businesses, including self-employment and businesses that never intend to become registered, startups refer to new businesses that intend to grow large beyond the solo founder. At the beginning, startups face high uncertainty and have high rates of failure, but a minority of them do go on to be successful and influential.Erin Griffith (2014)Why startups fail, according to their founders Fortune.com, 25 September 2014; accessed 27 October 2017 Actions Startups typically begin by a founder (solo-founder) or co-founders who have a way to solve a problem. The founder of a startup will begin market validation by problem interview, solution interview, and building a minimum viable product (MVP), i.e. a prototype, to develop and validate their business models. The startup process can take a long period of time (by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Virginia
Virginia, officially the Commonwealth of Virginia, is a state in the Mid-Atlantic and Southeastern regions of the United States, between the Atlantic Coast and the Appalachian Mountains. The geography and climate of the Commonwealth are shaped by the Blue Ridge Mountains and the Chesapeake Bay, which provide habitat for much of its flora and fauna. The capital of the Commonwealth is Richmond; Virginia Beach is the most-populous city, and Fairfax County is the most-populous political subdivision. The Commonwealth's population was over 8.65million, with 36% of them living in the Baltimore–Washington metropolitan area. The area's history begins with several indigenous groups, including the Powhatan. In 1607, the London Company established the Colony of Virginia as the first permanent English colony in the New World. Virginia's state nickname, the Old Dominion, is a reference to this status. Slave labor and land acquired from displaced native tribes fueled the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
