Helicopter transmission
The requirements which have to be met by castings in the aircraft industry are stringent in view of the freedom from error necessary in X raying and crack detection, as well as in the mechanical parameters to be achieved. An optimal casting technology has to be developed to cope with these demands. It may be the case that a number of technological cycles are necessary before this goal is achievable. For this purpose, rapid prototyping techniques offer the flexibility necessary to implement changes. Also, the worst case scenario, i.e. changing the casting position of a part, can be handled without additional molding costs. Simulation of mold filling and solidification can be used in order to substantiate the expected results.
Additional savings may be achieved if the prototypes for the first tests on the test bed do not have series characteristics. In this case, the time-consuming and cost-intensive development of an appropriate casting strategy may be cut considerably. Thanks to experience, it is possible to make available a high-value test stand part to be used for testing and refining new concepts.
Due to the great flexibility of the Rapid Prototyping techniques used, one may react to results and implement modifications based on experience even in the next casting within only a few hours or days. The expertise gained here may also be implemented later on when developing a suitable casting strategy for the series parts at the exceptional aircraft quality level.
