| 摘要： | One objective of the NASA-sponsored High Speed Civil Transport (HSCT) propulsion studies is to determine the potential benefits of alternative advanced technologies. These benefits should be explicitly expressed in terms of meeting either environmental acceptability or economic viability. The potential benefit information is used to screen alternative technology candidates to the most promising technologies that, if successfully developed, will enable the propulsion system to achieve high performance and low weight without unduly sacrificing favorable emissions and noise characteristics. A second objective is the provision of key information to high-level decision makers--enabling them to make rational decisions concerning the technology program content. It will be necessary to pursue more than one concept/technology until experimental validity is convincingly demonstrated. Some technologies will likely fail to achieve their stated goals, and timely program redirection depends upon far-sighted system studies to provide such information. |
