연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

Vehicle propulsion systems and methods of propulsion are disclosed, as well as embodiments of fans and airfoils, technology that in some applications of the invention can provide both lift and thrust, and propulsion via cross flow fan, manifold and a plurality of airfoils. In some embodiments the invention is directed to the production of lift and thrust, and propulsion generally, based from air produced by a cross flow fan in accordance with the invention disclosed herein. In still further embodiments, lift and thrust may yet be generated from air produced from the cross flow fan even when unpowered, such as in a loss of power or in a stall condition. Applications of the invention apply broadly to propulsion systems, generally; however, some preferred embodiments have particular application for vehicles characterized or used in application such as traditional private and commercial aircraft, ground effects vehicles, military applications, amphibious applications, aerospace, aeronautical, and non-traditional vehicles such as experimental air planes, space craft, hover craft, and the like. The invention in some embodiments comprises technologies addressing preferred air flow, lift, and thrust and the reduction of drag and circulation losses. The invention may be further applicable for incorporation in aircraft and other vehicles wherein the ability to maximize initial vertical lift and takeoff is important, such as in instant take-off and landing, as well as the abilities to hover, to control the flight and landing of aircraft, and control in power-loss scenarios, addressing the prevention of stalls and allowing for controlled descents under continued propulsion. In some embodiments, the invention is further applicable for aircraft, shuttles and other vehicles as a ram jet engine system as a further alternative propulsion technology, having no requirement for forward movement for propulsion upon take-off.
