为避免美国的直升机发动机对西欧的渗透,西欧主要发动机公司曾签约要合作研制这类小发动机.在这样的历史背景下,德国、法国和英国的发动机公司组成MTR公司,并于1989年开始研制MTR390发动机.目前,这项研制计划已历时近6年,正处于试飞研制阶段,不久后就将在“虎”直升机上投入使用. In order to avoid the infiltration of U.S. helicopter engines into Western Europe, major Western European engine companies signed a contract to jointly develop such small engines. Under such a historical background, engine companies from Germany, France and the United Kingdom formed MTR Corporation and started to develop them in 1989 MTR390 engine.At present, this development plan has lasted nearly 6 years, is in the stage of flight test development, will soon be put into use on the “tiger” helicopter.
