德国下一代民用发动机新技术

Several New Technologies Studied by Germany for Next Generation Civil Engine

德国MTU公司和德英合资的宝马·罗-罗公司正在实施由德国政府发起的为下一代民用发动机研究新技术的研究计划。编号为3E发动机的计划可能是导致下世纪初研制成生产型发动机的有涵道桨扇发动机验证机的第一步。3E发动机的资金来自德国政府的为期4年、投资6亿德国马克的民用航宇研究-支援一揽子计划。这项计划分为定翼机、旋翼机和发动机研究,并在1995到1998年之间进行。总计约1.44亿马克(1亿美元)指定用于3E发动机,其中MTU公司占的份额最多,达48％,而宝马·罗-罗公司占29％。根据这项政府的计划,两公司必须协调政府的和自已的资金。

The MTU and BMW Rolls-Royce are participating a German government-sponsored research programme to develop nevu technologies for the next generation civil engine. The MTU' s target is to have a 20% reduction in the number of stages , a 10% cut in length , a 20% cut in the number of blades in the HP compressor by 1998, compared with today' s technologies. The company also is developing advanced turbine technologies. The BMW Rolls-Royce is pursuing a two-stage combustor concept and planning to test the combustor in a core engine in the first half of 1997. The combustor tests will evaluate the NOx reduction potential of the combustor, and test its controls and fuel system under realistic flight conditions.
