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.

초록

An unmanned aerial vehicle (UAV) can be deployed from a small stowed package for flight and stowed back into the package after the flight is complete is disclosed. The UAV is retracted to a volume that is less than half of it's fully deployed volume. This allows the UAV to be transported to any desired field position on a truck or other convenient transportation. The UAV may also be launched from a ship deck. In a further aspect, the flexible deployment of the UAV will allow a single UAV to be used in place of multiple types of UAVs.

An unmanned aerial vehicle (UAV), comprising a fuselage;a telescoping wing assembly comprising a telescoping axis, said wing assembly comprising two wings, each further comprising: a plurality of concentric tubular mast segments coaxial with said telescoping axis, said mast segments configured to slide relative to adjacent mast segments;a plurality of ribs; anda plurality of skin segments each attached to at least one rib, said skin segments configured to slide relative to adjacent skin segments and said ribs configured to slide over at least on mast segment; anda wing root mechanism comprising: a vertical rotation pivot operatively coupling said wing assembly to said fuselage by a vertical rotation pin; anda horizontal rotation pivot operatively coupled to the telescoping wing assembly between the two wings and operatively coupled to the vertical rotation pivot by a horizontal rotation pin oriented perpendicularly to said vertical rotation pin, said vertical rotation pivot allowing said wing assembly to rotate around said vertical rotation pin between a stowed position in which the telescoping axis is parallel to an axis of the fuselage and a deployed position in which the telescoping axis is perpendicular to the axis of the fuselage, said horizontal rotation pivot allowing the wing assembly to tilt as a unit around said horizontal rotation pin into the stowed position. 2. The UAV of claim 1, wherein the fuselage further comprises: a front portion on one side of the wing root mechanism; anda tail portion on the opposite side of the wing root mechanism, said tail portion comprising a plurality of telescoping concentric tubular mast segments. 3. The UAV of claim 2, further comprising an empennage assembly rotatably attached to an end of the tail portion opposite the wing root mechanism. 4. The UAV of claim 1, wherein the wingspan of the wing assembly when fully extended is approximately 14 feet and further wherein the wing assembly when fully retracted has a wingspan such that the UAV may be stowed in a case with dimensions of approximately 51″×21″×12″. 5. The UAV of claim 1, wherein the wingspan of the wing assembly when fully extended is approximately 8 feet and further wherein the wing assembly when fully retracted has a wingspan such that the UAV may be stowed in a case with dimensions of approximately 40″×21″×12″. 6. The UAV of claim 1, wherein the wingspan of the wing assembly when fully extended is approximately 14.8 feet and further wherein the wing assembly when fully retracted has a wingspan such that the UAV may be stowed in a case with dimensions of approximately 53.5″×38″×26″. 7. The UAV of claim 1, wherein the wingspan of the wing assembly when fully extended is approximately 22 feet and further wherein the wing assembly when fully retracted has a wingspan such that the UAV may be stowed in a case with dimensions of approximately 80″×40″×22″. 8. The UAV of claim 1, wherein the wingspan of the wing assembly when fully extended is approximately 27 feet and further wherein the wing assembly when fully retracted has a wingspan such that the UAV may be stowed in a case with dimensions of approximately 100″×48″×35″. 9. The UAV of claim 1 further comprising one or more imaging sensor devices. 10. A fixed-wing unmanned aerial vehicle (UAV), comprising: a fuselage;a telescoping wing assembly having a telescoping axis, said wing assembly comprising two wings each further comprising: a plurality of concentric tubular mast segments coaxial with said telescoping axis, said mast segments configured to slide relative to adjacent mast segments;a plurality of ribs; anda plurality of skin segments each attached to at least one rib, said skin segments configured to slide relative to adjacent skin segments and said ribs configured to slide over at least on mast segment;a wing root fitting further comprising: a vertical rotation pivot operatively coupled to the fuselage by a vertical rotation pin; anda horizontal rotation pivot operatively coupled to the telescoping wing assembly between the two wings and operatively coupled to the vertical rotation pivot by a horizontal rotation pin oriented perpendicularly to said vertical rotation pin, said vertical rotation pivot allowing the wing assembly to rotate around said vertical rotation pin between a position in which the telescoping axis is parallel to an axis of the fuselage and a position in which the telescoping axis is perpendicular to the axis of the fuselage and said horizontal rotation pivot allowing the wing assembly to tilt around said horizontal rotation pin. 11.
