It appears logical, that in view of changing economic parameters worldwide, future helicopter engines should be developed alpog the lines of non sophisticated concepts, cautions cycle selection in view of small engine size, development risk to be reduced by technology programs, simplicity of design, with fewer parts and modules, most economic manufacturing processes to achieve low production costs, low spare parts' prices, and high reliability i.e. more early testing when discovery of problems is less costly, good maintainability. Advanced technology should be applied on the next generation engines to improve LCC instead of achieving pure performance. Thus not the performance related technological limits or properties appear to require improvement in the first place but their cost driving factors which will decide whether we can afford military systems in the future. The question will inevitably arise of how the certainly larger front end investment on better engine design, development and more thorough testing to get all those properties into an engine shall be paid for. For the time being, the answer should be: more international cooperation. (Wassmann)
