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.

A multimodal vehicle includes a ground based vehicle with an attached high-capacity airfoil parachute for deployment. The ground based vehicle includes a drive system for use on either land, water or both. Furthermore, the ground based vehicle is sized and dimensioned for transport of multiple vehicles in a cargo plane. The high-capacity airfoil parachute allows high-altitude deployment of the multimodal vehicle. The risers to the parachute may be adjusted for powered parachute flight rather than free fall flight. The ground based vehicle may include a ...

The invention claimed is: 1. A multimodal vehicle comprising: a ground operable vehicle having an air propulsion source dischargeable from an aircraft in-flight; a multimodal ram air parachute operable in one free fall mode as a free fall parachute and in another powered parachute mode as a powered parachute attached to an upper portion of the ground operable vehicle deployable as a free fall parachute in said free fall mode following discharge of the ground operable vehicle from the aircraft for controlled descent of the ground operable vehicle to a target location and redeployable upon landing of the ground operable vehicle at the target location as a powered parachute in said powered parachute mode for controlled takeoff, flight and landing of the ground operable vehicle using said air propulsion source; a reefing mechanism operatively connected to said multimodal ram air parachute, said reefing mechanism controlling the rate at which said multimodal ram air parachute opens to prevent damage to said multimodal ram air parachute; and a riser adjustment mechanism allowing changes in the length of risers attaching said ground operable vehicle to said multimodal ram air parachute to controllably select between a front edge down canopy to provide operation in said free fall mode and a front edge up canopy to provide operation in said powered parachute mode. 2. The multimodal vehicle according to claim 1, wherein the ground operable vehicle includes wheels and a drive mechanism attached to the wheels for operation on land. 3. The multimodal vehicle according to claim 1, wherein the ground operable vehicle includes a drive mechanism for operation on water. 4. The multimodal vehicle according to claim 1, wherein the ground operable vehicle includes armament. 5. The multimodal vehicle according to claim 1, wherein the riser adjustment mechanism changes the parachute trim between a position for free fall and a position for powered flight. 6. The multimodal vehicle according to claim 1, wherein the ram air parachute is packable. 7. The multimodal vehicle according to claim 1, wherein said source of air propulsion includes a propeller attached to a drive mechanism of the ground vehicle for powered flight. 8. The multimodal vehicle according to claim 1 further comprising: control means operable in the ground vehicle for controlling direction during flight. 9. The multimodal vehicle according to claim 8, wherein the control means includes means for shifting the weight of the vehicle relative to the parachute. 10. The multimodal vehicle according to claim 8, wherein the control means includes steering lines attached to the parachute. 11. A method of operating a multimodal vehicle including a ground operable vehicle having an air propulsion source and a multimodal ram air parachute operable in one free fall mode as a free fall parachute and in another powered parachute mode as a powered parachute that is attached to the ground operable vehicle, the method including the steps of: discharging the ground operable vehicle from a delivery aircraft; deploying the multimodal parachute for operation in said free fall mode as a free fall parachute; steering the ground operable vehicle to a target location during descent using the multimodal parachute in said free fall mode; landing the ground operable vehicle on the ground using the multimodal parachute in said free fall mode; redeploying upon landing the multimodal parachute for operation in said powered parachute mode as a powered parachute including of changing the trim of the parachute relative to the ground vehicle between a position for falling and a position for powered flight; and causing the ground operable vehicle to takeoff, fly and land using the multimodal parachute in said powered parachute mode and said air propulsion source. 12. The method of operating the multimodal vehicle according to claim 11, further comprising the step of driving the ground vehicle while on the ground. 13. A multimodal vehicle comprising: a ground operable vehicle having an air propulsion source and dischargeable from an aircraft inflight; a multimodal ram air parachute, operable in one free fall mode as a free fall parachute and in another powered parachute mode as a powered parachute, attached to an upper portion of the ground operable vehicle and deployable as a free fall parachute in said free fall mode following discharge of the ground operable vehicle from the aircraft for controlled descent of the ground operable vehicle to a target location and redeployable upon landing of the ground operable vehicle at the target location as a powered parachute in said powered parachute mode, for controlled takeoff, flight and landing of the ground operable vehicle using said air propulsion source; and a riser adjustment mechanism allowing changes in the length of risers attaching said ground operable vehicle to said multimodal ram air parachute to controllably select between a front edge down canopy to provide operation in said free fall mode and a front edge up canopy to provide operation in said powered parachute mode. 14. A multimodal vehicle comprising: a ground operable vehicle having an air propulsion source and dischargeable from an aircraft in-flight; a multimodal ram air parachute, operable in one free fall mode as a free fall parachute and in another powered parachute mode as a powered parachute, attached to an upper portion of the ground operable vehicle and deployable as a free fall parachute in said free fall mode following discharge of the ground operable vehicle from the aircraft for controlled descent of the ground operable vehicle to a target location, and redeployable upon landing of the ground operable vehicle at the target location as a powered parachute in said powered parachute mode for controlled takeoff, flight and landing of the ground operable vehicle using said air propulsion source; a riser adjustment mechanism allowing changes in the length of risers attaching said ground operable vehicle to said multimodal ram air parachute to controllably select between a front edge down canopy to provide operation in said free fall mode and a front edge up canopy to provide operation in said powered parachute mode; and control means for providing steering in said free fall mode and in said powered parachute mode.
