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 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 submerged ram air turbine generating system adapted for use in a pod mounted to the wing of an aircraft comprises a submerged inlet extending substantially entirely around the outer surface of the pod housing, a stator in the form of adjustable or fixed inlet guide vanes which direct an air stream to a hybrid ram air turbine having alternating turbine blades and splitters, and, a number of adjustable exhaust panels which are movable with respect to one or more exhaust openings in the pod housing.

1. A ram air turbine generating apparatus, comprising: a pod including a pod housing having a forward end, an aft end and an outer surface collectively defining a pod interior;a submerged inlet formed in said pod housing between said forward end and said aft end, said submerged inlet extending substantially entirely around said outer surface of said pod housing;a stator located in said pod interior downstream from said submerged inlet;a turbine located downstream from said stator;a generator coupled to said turbine; andat least one exhaust opening formed in said pod housing. 2. The apparatus of claim 1 in which said submerged inlet has an inlet opening which is substantially flush with said outer surface of said pod housing. 3. The apparatus of claim 2 in which said inlet opening of said submerged inlet is formed with a curved surface, said curved surface being effective to minimize flow separation of a stream of air entering said submerged inlet from outside of said pod interior. 4. The apparatus of claim 2 in which said submerged inlet decreases in cross sectional area which decreases in a direction from said inlet opening toward said pod interior. 5. The apparatus of claim 1 further including a closure device located within said submerged inlet, said closure device being movable between an open position in which a flow of air is permitted to enter said pod interior through said submerged inlet and a closed position in which the flow of air is substantially prevented from entering said pod interior. 6. The apparatus of claim 5 in which said closure device comprises a number of louvers mounted within said submerged inlet, each of said louvers being movable between said open position and said closed position. 7. A ram air turbine generating apparatus, comprising: a pod including a pod housing having a forward end, an aft end and an outer surface collectively defining a pod interior;a submerged inlet located between said forward end and said aft end of said pod housing, said submerged inlet extending substantially entirely around said outer surface of said pod housing;a stator located in said pod interior downstream from said inlet;a turbine located downstream from said stator;a generator coupled to said turbine;a number of exhaust panels mounted to said pod housing, each of said exhaust panels being movable between an open position and a closed position with respect to at least one exhaust opening formed in said pod housing, said exhaust panels when in said open position being effective to reduce pressure within at least a portion of said pod interior. 8. The apparatus of claim 7 in which said open position of said exhaust panels comprises any position in which said exhaust panel is spaced at an angle of up to about 30° relative to said outer surface of said pod housing. 9. The apparatus of claim 7 in which each of said exhaust panels is mounted by at least one hinge to said pod housing, said exhaust panels being pivotal about said hinge between said open and closed positions. 10. The apparatus of claim 9 further including a drive mechanism and an actuator ring coupled to said drive mechanism. 11. The apparatus of claim 10 further including a pivot arm connected between each of said exhaust panels and said actuator ring, said actuator ring being rotatable in one of a clockwise and counterclockwise direction in response to operation of said drive mechanism to cause each of said pivot arms to move an exhaust panel to said open position, and said actuator being rotatable in the other of a clockwise and counterclockwise direction in response to operation of said drive mechanism to cause each of said pivot arms to move an exhaust panel to said closed position. 12. The apparatus of claim 11 in which said drive mechanism is a motor coupled to a gear reducer. 13. A ram air turbine generating apparatus, comprising: a pod including a pod housing having a forward end, an aft end and an outer surface collectively defining a pod interior;a submerged inlet located between said forward end and said aft end of said pod housing, said submerged inlet extending substantially entirely around said outer surface of said pod housing;a stator located in said pod interior downstream from said inlet;a turbine located downstream from said stator, said turbine having a turbine housing whose cross sectional area decreases in a forward to aft direction, a number of circumferentially spaced turbine blades being mounted to said turbine housing and a number of splitters each being mounted to said turbine housing in between adjacent turbine blades;a generator coupled to said turbine;at least one outlet opening formed in said pod housing. 14. The apparatus of claim 13 in which said decreasing cross sectional area of said turbine housing is effective to create a reduction in pressure within at least a portion of said pod interior. 15. The apparatus of claim 13 in which said turbine housing has a forward end and an aft end, each of said turbine blades extending between said forward end and said aft end of said turbine housing, each of said splitters extending from said forward end of said turbine housing to a terminal location which is spaced from said aft end thereof. 16.

The apparatus of claim 13 in which said stator includes a number of circumferentially spaced inlet guide vanes each positioned to direct said air stream onto said turbines blades and said splitters, said number of inlet guide vanes being different than said number of turbine blades and said number of splitters, collectively. 18. The apparatus of claim 13 in which said turbine blades function substantially as an impulse turbine blade. 19. The apparatus of claim 13 in which said splitters function substantially as a reaction turbine blade. 20. The apparatus of claim 13 in which said turbine housing is substantially frusto-conical in shape. 21. A ram air turbine generating apparatus, comprising: a pod including a pod housing having a forward end, an aft end and an outer surface collectively defining a pod interior;a submerged inlet located between said forward end and said aft end of said pod housing, said submerged inlet extending substantially entirely around said outer surface of said pod housing, an air stream entering said submerged inlet and moving through said pod interior;a turbine located within said pod interior, said turbine having a number of turbine blades and splitters;a stator located between said submerged inlet and said turbine, said stator including a number of circumferentially spaced inlet guide vanes each oriented at an angle relative to said air stream flowing through said pod interior so as to direct said air stream into engagement with said turbine blades and said splitters, said angle of said inlet guide vanes being adjustable to vary the location at which said air stream engages said turbine blades and said splitters;a generator coupled to said turbine;at least one outlet opening formed in said pod housing. 22.
