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.

A roadable aircraft and an associated method are disclosed herein. The roadable aircraft includes a body extending along a longitudinal axis and operable to house a human occupant. The roadable aircraft also includes at least first and second wings each being selectively moveable relative to the body between a retracted position for stowing and an extended position for flight. Each of the first and second wings extend a wing cord along the longitudinal axis when in the extended position between a leading edge and a wing trailing-edge vectoring nozzle. The roadable aircraft also includes a system for directing first and second streams of air through the first and second wings, respectively, and out of the first and second wing trailing-edge vectoring nozzles such that thrust for the body is generated. In addition, embodiments of the invention can include a plurality of deployable, vectoring lift fans which are also capable of producing thrust. Thrust for VTOL and cruise flight can be achieved by combining the thrust generated by the wing trailing-edge vectoring nozzles and/or the vectoring lift fans. An alternative to the wing trailing-edge vectoring nozzles would be to vector the entire wing.

The roadable aircraft of claim 9 wherein said first and second fans are spaced from said first and second wings along said longitudinal axis when said first and second wings are in said extended position. 11. A method comprising the steps of: extending a body adapted to house a human occupant along a longitudinal axis;selectively moving at least first and second wings relative to said body between a retracted position for stowing and an extended position for flight, each of said first and second wings extending a wing cord along said longitudinal axis when in said extended position between a leading edge and a wing trailing-edge vectoring nozzle, said first and second wings each have a longitudinal wing span extending generally along said longitudinal axis when in said retracted position and which do not overlap one another when in said extended position; anddirecting first and second streams of air through said first and second wings, respectively, and out of said first and second wing trailing-edge vectoring nozzles with an air-moving system such that thrust for said body is generated. 12. The method of claim 11 further comprising the step of: pivoting said wing trailing-edge vectoring nozzles to vary the direction of thrust acting on the body. 13. The method of claim 11 further comprising the step of: supplementing the thrust generated by the first and second air streams with at least one fan mounted on the body, wherein the at least one fan is offset from the first and second wings along the longitudinal axis and does not overlap any portion of the first and second wings when the first and second wings are in the extended position. 14.
