再使用ロケット実験とは日本の宇宙航空研究開発機構 (JAXA) の研究プロジェクトのひとつで、英語表記 (Reusable Vehicle Testing) の略称でRVTとも呼ぶ。また、本実験で製作した実験用機体である、再使用ロケット実験機のこともRVTと呼ぶ。本実験の目的は、完全再使用ロケット (RLV) の開発に必要な技術の習得である。
, 재사용 로켓 실험(일본어: 再使用ロケット実験, 영어: Reusable Veh … 재사용 로켓 실험(일본어: 再使用ロケット実験, 영어: Reusable Vehicle Testing), 일명 RVT는 일본 우주항공연구개발기구에서 1998년부터 2003년까지 진행한 계획이다. 이 계획에서 RLV 로켓의 반복 시험발사를 위해 여러 시제기가 제작되었으며, 4기의 우주선이 개발되었다. 시제기의 디자인은 미래의 RLV 계획을 위한 즉시 발사, 고속 회선, 높은 출력, 경량 구조 및 재질등 다양한 기술적 과제들을 고려했다. 재사용 로켓 실험에서는 지상 실험과 비행 실험이 모두 이루어졌으며 비행 실험은 일본 북부 노시로시의 우주과학연구소 실험장에서 진행되었다. 일본 우주항공연구개발기구는 재사용 로켓 실험에서 시연된 기술글을 통해 고고도 RLV 로켓 개발을 추진하고 있다. 100 km 고도까지 100 kg의 중량을 수송할 수 있는 로켓이 계획되고 있다. 이 로켓에는 재사용 로켓 실험을 통해 시연된 엔진과 자세제어 장비 등이 사용된다. 로켓의 개발과 시험발사까지 5년, 비용은 500억 엔이 소요될 것으로 예상되었다. 로켓은 하루에 5회 비행할 수 있다. 2500회 비행 시 평균 발사 비용은 1만 엔으로 예상되어, 현재 수백만 엔이 소요되는 로켓 발사 비용을 크게 줄일 것으로 기대되고 있다.재 수백만 엔이 소요되는 로켓 발사 비용을 크게 줄일 것으로 기대되고 있다.
, Le Reusable Vehicle Testing (RVT) (anglais … Le Reusable Vehicle Testing (RVT) (anglais : essai de véhicule réutilisable) est un projet de l'Institut des sciences spatiales et astronautiques (ISAS) puis de l'Agence d'exploration aérospatiale japonaise (JAXA), lancé en 1998 et interrompu en 2009, dont l'objectif était de tester le concept de lanceur réutilisable au moyen d'une série de véhicules expérimentaux. Quatre véhicules complets ont été développés pour mettre au point plusieurs techniques : le lancement sur demande, la réduction de la durée de remise en condition entre deux lancements, l'accroissement des performances, le recours à des matériaux et des structures légères. Le projet comprenait des essais au sol et en vol : ces derniers ont été effectués au Centre d'essais de fusées de Noshiro de l'ISAS, au nord de la principale île du Japon. Les quatre véhicules mis au point au cours du projet ont reçu les appellations de RVT #1 à RVT #4. Les tests au sol et les essais en vol ont reçu un nom de RVT-1 à RVT-11. en vol ont reçu un nom de RVT-1 à RVT-11.
, The Reusable Vehicle Testing (RVT) project … The Reusable Vehicle Testing (RVT) project was conducted by the Japanese Space Agency (JAXA) from 1998 until 2003. The project involved a series of experimental vehicles to test repeated flights of a reusable rocket. Four complete vehicles were developed during the project. The design of the experimental vehicles addressed various technical challenges for future Reusable Launch Vehicles (RLV) such as flight on demand, quick turnaround, higher performance, lightweight structures and materials. The project involved ground and flights tests with the flight testing conducted at the Institute of Space and Astronautical Science (ISAS) Noshiro Rocket Testing Center in the northern part of Japan's main island. JAXA proposed to develop a reusable high altitude rocket based on the technologies demonstrated in the RVT project. The rocket would take a payload of about 100 kg to an altitude of 100 km. RVT-derived equipment such as engines and attitude control will be used. The development and flight testing is expected to take 5 years and the cost is estimated at 50 billion yen. The rocket, capable of five flights in a day. The cost per flight, based on 2500 flights, is expected to be 10,000 yen, reducing the per flight cost compared to current day expendable rocket systems, which cost between 2 and 6 billion yen. The experimental payloads will be recovered after the flight, which will also minimize costs for the payload developer. Moreover, it will be possible to stop and hover the vehicle at any altitude, which is impossible with conventional sounding rockets.ssible with conventional sounding rockets.
