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

A personal flight device includes a housing securable to the pilot. The device includes at least one pair of ducted fans, one fan of each pair mounted to each side of the housing. The axis of rotation of each fan is fixed relative to the housing. At least one engine is mounted on the housing for driving the fans and both fans rotate in the same direction for producing thrust. Three pairs of control surfaces, with one control surface of each pair is mounted below each fan of the one or each pair of fans.

1. A personal flight device which includes: a housing which is securable to the pilot;at least one pair of ducted fans, one fan of each pair of fans mounted to one side of the housing, and the other fan of each pair of fans mounted to the other side of the housing;wherein each fan rotates about an axis of rotation so as to draw air through the corresponding duct from an entry end of the duct to an exit end of the duct;and wherein the axis of rotation of each fan is fixed relative to the housing;at least one engine mounted on the housing for driving the fans, wherein both or all fans rotate in the same direction for producing thrust;at least three pairs of control surfaces for at least one pair of the at least one pair of fans, with one control surface of each pair of control surfaces mounted below one fan of the at least one of the at least one pair of fans, and the other control surface of each pair of control surfaces being mounted below the other fan of the at least one of the at least one pair of fans, such that air leaving said fan impacts on said control surface;one pair of control surfaces of said at least three pairs of control surfaces being configured to control yaw, one pair of control surfaces of said at least three pairs of control surfaces being configured to control pitch, and one pair of control surfaces of said at least three pairs of control surfaces being configured to control roll; two of said at least three pairs of control surfaces being mounted external to, and spaced from, the ducts of a corresponding pair of fans, a third of said at least three pairs of control surfaces mounted to and across the exit end of the ducts of the corresponding pair of fans;control means for controlling the orientation of said control surfaces relative to said fans. 2. The personal flight device as claimed in claim 1 wherein each fan is secured to the housing such that the axis of rotation of each fan is substantially vertical when the device is secured to a pilot standing upright. 3. The personal flight device as claimed in claim 1 wherein the engine is selected from the group consisting of: two-stroke internal combustion engines, four stroke internal combustion engines, rotary engines, gas turbine engines. 4. The personal flight device as claimed in claim 1, further including a drive means arranged to be driven by the at least one engine, said drive means being configured to drive the at least one pair of fans. 5. The personal flight device as claimed in claim 4, wherein the drive means comprises a single drive. 6. The personal flight device as claimed in claim 4, wherein the drive means comprises a double drive. 7. The personal flight device as claimed in claim 5 or claim 27, wherein the drive means includes a drive selected from the group consisting of: chain drives, fluid drives, belt drives. 8. The personal flight device as claimed in claim 1, wherein the device further includes a set of stators arranged in each fan duct to straighten the airflow leaving that fan. 9. The personal flight device as claimed in claim 8, wherein the stators of each set have one end secured to an inner wall of the duct and another end secured to a hub of the fan within the duct. 10. The personal flight device as claimed in claim 9, wherein each stator has a curved aerofoil cross-section. 11. The personal flight device as claimed in claim 8, wherein each of the pair of control surfaces configured to control yaw is mounted diametrically across the exit end of a duct of the corresponding pair of fans and is configured to be pivotable about an axis substantially perpendicular to the axis of rotation of the corresponding fan, such that movement of said yaw control surfaces by said control means yaws the device. 12. The personal flight device as claimed in claim 1, or claim 11, wherein each of the pair of control surfaces configured to control roll is mounted below, and spaced from, the exit end of a duct of the corresponding pair of fans, each said control surface being configured to be pivoted about an axis substantially perpendicular to the longitudinal axis of the corresponding fan, such that movement of said roll control surfaces by said control means rolls the device. 13.
