Doug Fisher: 3729. Application of SAWE Course ‘Developing Basic Parametric Methods’ to Nacelle Weight Estimating. 2019.



This paper details how the learning contained in SAWE course ‘Developing Basic Parametric Methods’ was applied at Collins Aerospace for estimating nacelle weights of new commercial and business jet aircraft. Collins has decades of experience developing nacelles and a large database of historical weight data, but has not effectively leveraged that data into better weight estimating tools. Learning from this course was applied to develop improved methods of estimating the weight of nacelles for new product proposals. This has allowed us to not only provide better weight estimates but also better understand the limits of our data and estimating methods.
