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 reusable, mach-velocity mobile platform delivers a weapons payload via vertical launch, powerless glide, weapons release, and landing operation phases. The platform includes a generally tubular shaped body having an aft and forward end, and a payload section. An arch wing is supported by the body aft end. The arch wing has an upper and a lower wing joined at distal ends by two curved end plates. A nose assembly is connected at the forward end having an upward directed fixed angle-of-attack to generate forward end lift. Thermal tiles attached under the body and the lower wing under-side radiate/dissipate heat generated during a high angle-of-attack platform reentry. Radar absorptive or radar translucent material is used. The platform preferably discharges payload from the aft end for safe separation. A landing gear is extended for the landing phase of operation.

The mobile platform of claim 2, further comprising: said upper wing and said curved end-plate formed of a radar translucent material; said lower wing formed from one of a metal and a composite material; and a radar absorbing material applied to external facing surfaces of said lower wing. 4. The mobile platform of claim 3, wherein said upper wing further comprises: an upper wing forward point disposed approximately coincident with a body longitudinal axis extending along said tubular shaped body; a swept wing angle measured from said upper wing forward point to a forward facing point of each of said upper wing distal ends. 5. The mobile platform of claim 4, wherein said lower wing further comprises: a lower wing forward point disposed approximately coincident with said body longitudinal axis and said swept wing angle; and said swept wing angle measured from said lower wing forward point to a forward facing point of each of said lower wing distal ends; wherein said lower wing forward point is positioned forward of said upper wing forward point such that said lower wing shields said upper wing from elevated temperatures occurring when said mobile platform operates at a reentry phase high angle-of-attack. 6. The mobile platform of claim 5, wherein said lower wing, said upper wing and said curved end plate further comprise: a generally rounded leading edge; and a generally squared-off trailing edge. 7. The mobile platform of claim 5, further comprising: said lower wing having a starboard wing half and a port wing half; a pair of elevons symmetrically spaced about said body longitudinal centerline, one of said elevons disposed on each said split upper surface of said starboard wing half and said port wing half; and a pair of ailerons each positioned adjacent to one of said elevons. 8. The mobile platform of claim 1, wherein said upward fixed angle-of-attack of said nose assembly varies over a range of approximately 4 degrees to approximately 15 degrees.9. A reusable, mach-velocity mobile platform comprising: a generally tubular shaped body having an aft end, a forward end, and a payload section disposed about a longitudinal axis of said body; an arch wing supported at said aft end of said body; a nose assembly connected at said forward end, said nose assembly having an upward fixed angle-of-attack to provide lift force at said forward end; and a plurality of landing devices extendable from said body; a payload including one of an equipment package and a munitions package stowable in said payload section; and a rear-release discharge face to discharge said payload from said aft end of said body during said weapons release phase; wherein said platform is adaptable for operation phases including at least one of a propelled vertical launch phase, a powerless glide phase, a weapons release phase, and a landing phase. 10.
