双语：未来飞机应该像飞碟一样(图)

航空工程师们目前正探讨设计新一代的绿色环保飞机

　　Aviation engineers are designing a more environmentally sustainable airplane that may overturn long-held notions of flight engineering.

　　"I want to get rid of the image of a cylindrical body with wings," said Etnel Straatsma of Delft University of Technology in The Netherlands. The plane of the future, in Straatsma's vision, might be as wild as a flying saucer. She and other engineers are toying with lighter materials and some are pondering ideas as radical as returning to propeller-driven planes as an eco-friendly alternative to passenger jets.

　　Straatsma heads the recently-formed CleanEra project, which aims to design an "ultra-eco-friendly plane" that releases 50 percent less carbon dioxide per passenger-mile than current airliners. The project's "greenliner"—depicted in design illustrations as a flying saucer—would also reduce other pollutants and noise, in line with recommendations from the European Aerospace Commission, ACARE.

　　航空工程师们目前正探讨设计新一代的绿色环保飞机，那将在很大程度上颠覆传统的飞行工程学设计理念。

　　荷兰代夫特工业大学的伊特内尔·斯特拉斯玛说：“我想摆脱(飞机一贯的)长着翅膀的圆柱形机身的形象。”在斯特拉斯玛的想象里，未来飞机应该像飞碟一样野性。她和一些工程师们正打算使用一些更轻巧的材料，另一些工程师们则考虑重新启用螺旋桨飞机，用作生态环保的客机。

　　最近，斯特拉斯玛带头设立了“洁净时代”项目，旨在设计一款“超级生态环保的飞机”，这种飞机排放的二氧化碳每客位英里比目前客机的排放量要少50%。项目中的“绿色飞机”在设计图中被描绘成一个飞碟，它可以减少各种污染物质和噪音，符合欧洲航空研究顾问委员会推荐指标。
