Application of Point-Based Smoothing to the Design of Flying Surfaces
The aerospace industry is becoming increasingly competitive and customer focused. Competitive edge is achieved by providing the customer with an improved product with quicker lead times from concept through to manufacture. This can be facilitated using a fully integrated Digital Mock-Up (DMU), i.e. a complete solid model, which allows physical activities, such as clash detection on assembly and mock air battles, to be simulated within a virtual or synthetic environment. Design changes, such as alternative wing profiles or fuselage sections, can then be incorporated into the DMU at an earlier stage allowing more ‘what if..?’and ‘how to..?’ scenarios to be analysed without manufacturing any components.
