87 kg was determined. Besides an analysis of the structural strength, we identified additional factors, which could prevent the realization of a small-scaled modular design: the necessary installation space and the possibility to disconnect electrical cables. Current aviation regulations specify a maximal number of disconnection points of 60 L. Overmeyer and A. Bentlage Fig. 4 Installation space leading edge (worst case) electrical cables. The result is that for a small-scaled modular aircraft wing a complete pre-equipping of all electrical cables is currently not possible.
Figure 1 shows in an exemplary manner four rough design concepts of a smallscaled modular wing. In order to identify the best design concept, all concepts were evaluated on the basis of the following criteria: manufacturability of the components, easy assembly with a high proportion of preassembly, the use of state of the art technologies, the estimated weight and the comparability to the reference wing. Using this evaluation method variant 4 was chosen, especially because this variant shows a high level of comparability to the reference wing and is based upon currently available production technologies.
For the different operations spindles speed, power and cutting forces can be computed. This computation is very straightforward. In general the well-known basic models can be used. e. to machine productively, must be determined with more effort. Selection of the Kinematic Concept of the Machine In general, the most appropriate kinematic build-up for Blisk machining process should be selected. In addition to the usual design criteria like accessibility, ergonomics, floor space, etc. there are characteristics that are not very straightforward to evaluate, especially the machine dynamics for the application to keep finishing times as low as possible and the process stability to be able to us the optimal roughing strategies.
