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.

A vectorable nozzle includes a longitudinally extending upper fixed wall spaced upwardly and aftwardly of a longitudinally extending lower fixed wall and an aftwardly swept fixed ramp extending between the upper and lower fixed walls. The upper and lower fixed walls and the fixed ramp extend transversely between first and second fixed sidewalls. An outer nozzle wall is spaced apart from the upper and lower fixed walls and extends transversely between first and second fixed sidewalls. A nozzle flowpath is defined between the upper and lower fixed walls and the outer nozzle wall and the first and second fixed sidewalls. A sideways pivotable ramp structure pivotally connected to the lower fixed wall and pivotable between the sidewalls includes a longitudinally extending upper pivotable wall spaced upwardly and aftwardly of a longitudinally extending lower pivotable wall and an aftwardly swept pivotable ramp extending between the upper and lower pivotable walls.

What is claimed is: 1. A vectorable nozzle comprising: a longitudinally extending upper fixed wall spaced upwardly and aftwardly of a longitudinally extending lower fixed wall, an aftwardly swept fixed ramp extending between the upper and lower fixed walls, the upper and lower fixed walls and the fixed ramp extending transversely between first and second fixed sidewalls, an outer nozzle wall spaced apart from the upper and lower fixed walls, extending transversely between first and second fixed sidewalls, a nozzle flowpath defined between the upper and lower fixed walls and the outer nozzle wall and the first and second fixed sidewalls, a sideways pivotable ramp structure pivotally connected to the lower fixed wall and pivotable between the sidewalls, and the pivotable ramp structure including a longitudinally extending upper pivotable wall spaced upwardly and aftwardly of a longitudinally extending lower pivotable wall and an aftwardly swept pivotable ramp extending between the upper and lower pivotable walls. 2. A vectorable nozzle as claimed in claim 1 further comprising the upper pivotable wall including a widthwise aftwardly tapered section. 3. A vectorable nozzle as claimed in claim 2 further comprising the tapered section having an isosceles triangular planform area including side edges extending equi-angularly aftwardly from a base line between the tapered section and a non-tapered section of the upper pivotable wall. 4. A vectorable nozzle as claimed in claim 3 further comprising taper angles between the side edges and the base line and the taper angles sized for allowing the side edges to substantially abut respective ones of the sidewalls when the pivotable ramp structure is pivoted sideways. 5. A vectorable nozzle as claimed in claim 4 further comprising a fin attached to the pivotable ramp structure. 6. A vectorable nozzle as claimed in claim 5 further comprising the fin being attached to the pivotable ramp structure along at least longitudinally extending first and second portions of the lower pivotable wall and the pivotable ramp respectively. 7. A vectorable nozzle as claimed in claim 6 further comprising the fin extending longitudinally over a pivot point where the ramp structure is pivotally connected to the lower fixed wall. 8. A vectorable nozzle as claimed in claim 2 further comprising: the upper pivotable wall including a widthwise aftwardly tapered section and a base line between the tapered section and a non-tapered section of the upper pivotable wall, a throat extending substantially downward across the nozzle flowpath from the outer nozzle wall to the ramp structure, and the tapered and non-tapered sections of the upper pivotable wall being contoured so that the throat extends widthwise substantially along the base line during vectored and unvectored operation of the nozzle. 9. A vectorable nozzle as claimed in claim 8 further comprising the tapered section having an isosceles triangular planform area including side edges extending equi-angularly aftwardly from the base line between the tapered and the non-tapered sections of the upper pivotable wall. 10. A vectorable nozzle as claimed in claim 9 further comprising taper angles between the side edges and the base line and the taper angles sized for allowing the side edges to substantially abut respective ones of the sidewalls when the pivotable ramp structure is pivoted sideways. 11. A vectorable nozzle as claimed in claim 10 further comprising a fin attached to the pivotable ramp structure. 12. A vectorable nozzle as claimed in claim 11 further comprising the fin being attached to the pivotable ramp structure along at least longitudinally extending first and second portions of the lower pivotable wall and the pivotable ramp respectively. 13. A vectorable nozzle as claimed in claim 12 further comprising the fin extending longitudinally over a pivot point where the ramp structure is pivotally connected to the lower fixed wall. 14. A vectorable nozzle as claimed in claim 1 further comprising an upper triangular surface of the upper fixed wall bounding nozzle flowpath and at least a portion of the upper triangular surface extending aftwardly of the first and second fixed sidewalls to an apex of the triangular surface. 15. A vectorable nozzle as claimed in claim 14 further comprising the upper pivotable wall including a widthwise aftwardly tapered section. 16. A vectorable nozzle as claimed in claim 15 further comprising the tapered section having an isosceles triangular planform area including side edges extending equi-angularly aftwardly from a base line between the tapered section and a non-tapered section of the upper pivotable wall. 17. A vectorable nozzle as claimed in claim 16 further comprising taper angles between the side edges and the base line and the taper angles sized for allowing the side edges to substantially abut respective ones of the sidewalls when the pivotable ramp structure is pivoted sideways. 18. A vectorable nozzle as claimed in claim 17 further comprising a fin attached to the pivotable ramp structure. 19. A vectorable nozzle as claimed in claim 18 further comprising the fin being attached to the pivotable ramp structure along at least longitudinally extending first and second portions of the lower pivotable wall and the pivotable ramp respectively. 20. A vectorable nozzle as claimed in claim 19 further comprising the fin extending longitudinally over a pivot point where the ramp structure is pivotally connected to the lower fixed wall. 21. A vectorable nozzle as claimed in claim 15 further comprising: the upper pivotable wall including a widthwise aftwardly tapered section and a base line between the tapered section and a non-tapered section of the upper pivotable wall, a throat extending substantially downward across the nozzle flowpath from the outer nozzle wall to the ramp structure, and the tapered and non-tapered sections of the upper pivotable wall being contoured so that the throat extends widthwise substantially along the base line during vectored and unvectored operation of the nozzle. 22. A vectorable nozzle as claimed in claim 21 further comprising the tapered section having an isosceles triangular planform area including side edges extending equi-angularly aftwardly from the base line between the tapered and the non-tapered sections of the upper pivotable wall. 23. A vectorable nozzle as claimed in claim 22 further comprising taper angles between the side edges and the base line and the taper angles sized for allowing the side edges to substantially abut respective ones of the sidewalls when the pivotable ramp structure is pivoted sideways. 24. A vectorable nozzle as claimed in claim 23 further comprising a fin attached to the pivotable ramp structure. 25. A vectorable nozzle as claimed in claim 24 further comprising the fin being attached to the pivotable ramp structure along at least longitudinally extending first and second portions of the lower pivotable wall and the pivotable ramp respectively. 26. A vectorable nozzle as claimed in claim 25 further comprising the fin extending longitudinally over a pivot point where the ramp structure is pivotally connected to the lower fixed wall.
