新一代舰用燃气轮机即将问世

Development of New Generation of Surface Warship Gas Turbine

自从60年代英国皇家海军决定水面舰艇动力采用燃气轮机以来,舰用燃气轮机获得了迅速发展。西方国家在发展舰用燃气轮机过程中选择了采用成熟的航空发动机改型的道路。英国的“泰恩”、“埃汶”、“斯贝”、“奥林巴斯”及RB211,美国的LM-2500、LM-500、LM-1600、FT-9等均被广泛用于海军舰艇,其中,通用电气公司的LM-2500是美国当前海军舰艇的主要动力。由于在航空发动机基础上衍生的轻型燃气轮机具有优异的性能,因此,是否采用燃气轮机已经成为海军装备现代化的一个重要标志。

Development of new 19 . 7MW WR-21 intercooled-recuperated (ICR) gas turbine for the US Navy's surface warship programe is on schedule . The gas turbine is derived from Rolls-Royce RB 211 and the programe is designed to reduce fuel consumption by better than 30% . In this article the ICR gas turbine programe, including research, development and testing, and some features of WR-21 are described .
