Assessment of Aero Engine Assemblability During Preliminary Design

Unabated growth of air traffic interacting with increasing competition between the airlines continuously raises the economic pressure in the aerospace supply chain. New products, such as aircrafts and aero engines, have to be designed to match the resulting requirements. Hence it is important to assess production cost as well as producibility of aero engines already at an early stage during preliminary design. Assessing the assemblability is a vital task in this context. The level of design detail which is required to realize such an assessment has been investigated using a low pressure turbine module as an example. It turns out that the level of detail currently offered by many preliminary design tools will have to be increased moderately.
