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) is designed for low-speed, low altitude, long endurance missions typical to UAVs of this size and class. The UAV structure is configured to be substantially impervious to small arms fire and to have a very small representative radar cross-section. The UAV is modular such that the main wings and tail wing assembly are quickly and easily, detached from the fuselage for ease of transport and to provide an airframe that is quickly and easily adapted to any particular mission.

The UAV according to claim 1, wherein the right main wing assembly, left main wing assembly and tail wing assembly are each comprised of a polystyrene foam core overlaid with aircraft grade plywood veneer. 3. The UAV according to claim 1, wherein the fuselage assembly is configured with exterior chine structures configured to enhance maneuverability and to reduce overall representative radar cross-section. 4. The UAV according to claim 1, wherein the fuselage assembly includes a payload access opening covered by a removable access panel. 5. The UAV according to claim 1, wherein the fuselage assembly includes an engine access opening covered by a removable access panel, and an engine connected to the fuselage assembly. 6. The UAV according to claim 5, wherein the engine comprises a push-type engine. 7. The UAV according to claim 5, wherein the engine comprises a pull-type engine. 8. The UAV according to claim 1, wherein the fuselage assembly includes a plurality of skeleton structures, the skeleton structures including a plurality of aligned through holes formed therein; the right main wing assembly and the left main wing assembly each includes a plurality of holes aligned with the through holes in the skeleton structures; the through holes of the first mounting plate and the second mounting plate are aligned with the through holes in the skeleton structures; and the plurality of tubes extend through the through holes in the skeleton structures and into the holes in the right main wing assembly and the left main wing assembly and through the through holes in the first mounting plate and the second mounting plate. 9. The UAV according to claim 8, wherein the tubes have different cross-sectional sizes. 10. An unmanned aerial vehicle (UAV) comprising: a fuselage assembly; a left main wing assembly removably attached to the fuselage; a right main wing assembly removably attached to the fuselage; and a tail wing assembly that includes a first tail boom assembly connected to a first mounting plate that is compressed between the left main wing assembly and the fuselage assembly, a second tail boom assembly connected to a second mounting plate that is compressed between the right main wing assembly and the fuselage assembly, and a tail wing section connected to the first and second tail boom assemblies; and the first mounting plate and the second mounting plate each includes a plurality of through holes, and a plurality of tubes extend from the fuselage assembly through the through holes in the first and second mounting plates and into the left and right main wing assemblies. 11.
