A next generation medium power helicopter engine will have to show significant advances, when compared with engines representing todays high standard of technology. Towards this end, reduced fuel consumption will be a prime contributor, but new development can only be justified, if it results in improved overall engine economics as well as reliability. The basis for success is the application of advanced but proven component technology. Design activities need to start well in advance of the actual engine program to define the environment for component development, with the target to have technology and design methodology available at the beginning of engine development. Starting off with an optimized thermodynamic cycle, it will be discussed which components need intensive research and development to render a mature and reliable first production engine. Present date results, with regards aerodynamic and structural technology, are presented from both rig and demonstrator test programs. (Wassmann)
