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.

An aircraft adapted for covert deployment and having low vulnerability to hostile detection and aggression is provided. The aircraft includes a fuselage having a pair of sidewalls and a bottom. The sidewalls and bottom form an armored payload bay. The aircraft additionally includes a pair of wings connected to the fuselage. The wings have a fixed wingspan constrained such that the aircraft can be transported within a larger aircraft. This allows for the aircraft to be aerial deployed from the larger aircraft. Each of the sidewalls include at least one pulse ejector thrust augmentor (PETA) bank that is canted outward. Therefore, a thrust exhaust produced by each PETA bank is directed down and away from a centerline of the payload bay. Furthermore, the bottom of the aircraft is adapted to allow ingress and egress of cargo, e.g. military troops, from the payload bay.

The aircraft of claim 4, wherein the plurality of layers includes a payload bay panel included in each sidewall. 12. The aircraft of claim 1, wherein the fuselage includes long, aligned edges adapted to reduce radar cross section returns. 13. The aircraft of claim 1, wherein an exterior surface of each sidewall is canted to reduce radar cross section side sector returns. 14. The aircraft of claim 1, wherein a cruise propulsion system is included within an interior portion of the fuselage to reduce radar cross section returns and acoustical detection. 15. The aircraft of claim 14, wherein the cruise propulsion system includes a high efficiency, high bypass turbofan to cool exhaust from the cruise propulsion system and thereby reduce infrared detection. 16. The aircraft of claim 1, wherein the fuselage includes a lower aft deck adapted to reduce infrared detection. 17. The aircraft of claim 1, wherein each PETA bank includes at least one absorber adapted to narrow an acoustical bandwidth of noise generated by each PETA propulsion device and thereby reduce acoustical detection. 18. The aircraft of claim 1, wherein the fuselage and wings include a camouflage scheme to reduce visual detection. 19. A vertical take off and landing (VTOL) aircraft comprising:a fuselage having a pair of sidewalls each having an outwardly canted outer surface such that top portions of the outer surfaces are in closer proximity to each other than bottom portions of the outer surfaces;a bottom adapted to form an armored payload bay and allow ingress and egress of cargo from the armored payload bay;a pair of wings connected to the fuselage, the wings adapted to allow the aircraft to be transported within a larger aircraft; andat least one pulse ejector thrust augmentor (PETA) bank integrally formed within each canted sidewall, each PETA bank including:a plurality of interconnected pulsejets, andat least one acoustic barrier adapted to narrow an acoustical b andwidth of noise generated by thrust exhaust produced by each PETA bank,wherein each PETA bank is canted outward such that the thrust exhaust produced by each PETA bank is directed down and outwardly away from a centerline of the armored payload bay. 20.
