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.

1. A drag-reducing aerodynamic vehicle system, comprising: a central fairing extending from a roof of a vehicle; andside fairings disposed on either exterior end surface of the central fairing, wherein the side fairings comprise airflow guide vanes protruding from an interior surface of the side fairings and wherein the airflow guide vanes attach to an exterior end surface of the central fairing;wherein air flows through the airflow guide vanes and is directed toward a rear of the vehicle to reduce air stagnation around the vehicle and accelerates air flow between the vehicle and a trailer attached to the vehicle to prevent air recirculation to reduce air pressure and drag on the vehicle. 2. The drag-reducing aerodynamic vehicle system of claim 1, wherein the airflow guide vanes slide into corresponding recesses disposed on the exterior end surfaces of the central fairing. 3. The drag-reducing aerodynamic vehicle system of claim 1, wherein the central fairing further comprises support vanes extending from an air facing surface of the central fairing. 4. The drag-reducing aerodynamic vehicle system of claim 1, wherein the side fairings include a bridge suspended over the central fairing, wherein the side fairings are attached to the support vanes of the central fairing. 5. The drag-reducing aerodynamic vehicle system of claim 1, wherein the exterior end surfaces of the central fairing converge toward a pedestal of the central fairing, wherein the pedestal is located at a mid-point of the vehicle. 6. The drag-reducing aerodynamic vehicle system of claim 5, wherein the pedestal (90) has a convex shape. 7. The drag-reducing aerodynamic vehicle system of claim 1, comprising a polymeric material selected from polybutylene terephthalate; acrylonitrile-butadiene-styrene; polycarbonate; polyethylene terephthalate; acrylic-styrene-acrylonitrile; acrylonitrile-(ethylene-polypropylene diamine modified)-styrene; phenylene ether resins; polyamides; phenylene sulfide resins; polyvinyl chloride; high impact polystyrene; polyolefins; or a combination comprising at least one of the foregoing. 8. The drag-reducing aerodynamic vehicle system of claim 1, wherein the airflow guide vanes extend angularly from the interior surface of the side fairings. 9. A process of making the drag-reducing aerodynamic vehicle system of claim 1, comprising: injection molding a central fairing including exterior end surfaces;injection molding side fairings comprising airflow guide vanes (78) protruding from an interior surface of the side fairings; andattaching the side fairings to the central fairing by attaching the airflow guide vanes to the exterior end surfaces of the central fairing;wherein air flows through the airflow guide vanes and is directed toward a rear of the vehicle to reduce air stagnation around the vehicle and accelerates air flow between the vehicle and a trailer attached to the vehicle to prevent air recirculation to reduce air pressure and drag on the vehicle. 10. The process of claim 9, further comprising molding indentations disposed on exterior end surfaces of the central fairing, wherein the side fairings are attached to the central fairing by inserting the airflow guide vanes into the indentations. 11. The process of claim 9, further comprising attaching the side fairings to support vanes extending from an air facing surface of the central fairing. 12. A process of making a drag-reducing aerodynamic vehicle system, comprising a body attached to a roof of a vehicle, wherein the body comprises an air inlet including slits in the body, wherein the slits are disposed laterally to one another on opposing sides of a bisection of the vehicle and wherein the slits extend a length all or part of the way from a top of the body to a bottom of the body; wherein the air inlet includes an air guide boss extending from an interior surface of the body; andwherein the air entering the air inlet exits through an outlet and moves toward a side and rear of the vehicle, thereby reducing the drag experienced by the vehicle and wherein the air guide boss adjusts an air stagnation point away from a windshield and accelerates air flow between the vehicle and a trailer attached to the vehicle to prevent air recirculation to reduce air pressure and drag on the vehicle, wherein the method comprises:injection molding in an injection mold a body configured for attachment to a roof of a vehicle with a sliding core, wherein the body comprises an air inlet extending through a surface of the body, wherein the air inlet includes an air guide boss extending from an interior surface of the body, wherein the air guide boss adjusts an air stagnation point away from a windshield to reduce air pressure and drag on the vehicle; andejecting the drag-reducing aerodynamic vehicle system from the injection mold using the sliding core. 13. A drag-reducing aerodynamic vehicle system, comprising: a frontal member in physical communication with a rear member, wherein the frontal member and the rear member extend from a roof of a vehicle, wherein the frontal member comprises fin boxes having airflow guide vanes disposed perpendicularly between sidewalls of the fin boxes;wherein air flows through the airflow guide vanes and is directed toward a rear of the vehicle to reduce air stagnation around the vehicle; andwherein the air flow guide vanes accelerate air flow between the vehicle and a trailer attached to the vehicle to prevent air circulation and reduce drag on the vehicle. 14. The drag-reducing aerodynamic vehicle system of claim 13, wherein the frontal member includes an outer casing and the rear member includes an inner casing. 15. The drag-reducing aerodynamic vehicle system of claim 13, wherein the frontal member includes an arcuate cap converging toward a centerline of the drag-reducing aerodynamic vehicle system. 16.
