3. 일 시 : 2004년 8월 26일 (목) 14:00 - 15:00

5. 내 용 : Access to space has always been a scientific priority for countries which can afford the prohibitive costs associated with launch. However, the large scale exploitation of space by the business community will require the cost of placing payloads into orbit be dramatically reduced for space to become a truly profitable commodity. To this end, a next generation propulsive technology called the Rocket Based Combined Cycle (RBCC) engine is currently under active research and development. These engines combine a rocket, ejector, ramjet, and scramjet propulsive cycle within a single engine environment.
Recently NASA, under the ISTAR (Integrated System Test of an Airbreathing Rocket) project, in combination with the industry based Rocket Based Combined Cycle Consortium (Boeing Rocketdyne, Aerojet, and Prett and Whitney), has been developing a flight weight, fuel-cooled, RBCC engine for planned ground testing in 2008. The National Aerospace Laboratory of Japan (now part of the Japan Aerospace Exploration Agency, JAXA) has also been involved in RBCC research with their E3 engine, based on previous experience with their E1 and E2 scramjet engine designs.
One of the key elements of a successful RBCC engine is an efficient ejector section. It is this component which is responsible for any increased performance, as compared to traditional rockets, during the low speed, low altitude phases of flight. Using simplified theoretical analyses one notes a tremendous potential for rocket ejectors. However, numerical simulations accounting for real world effects can yield more accurate assessments of the potential benefits of a given configuration. By examining various ejector designs, this seminar endeavors to illustrate the need and importance of continued research and investment in this area while highlighting several effective ejector configurations.
