Improved Model for Small-scale Turbofan Engine Weight Estimation

Evgeny Filinov, Yaroslav Ostapyuk

Abstract

Weight estimation plays a crucial role at the initial stages of gas turbine development. A number of weight estimation models are described in the open sources, but design data available at these stages is scarce, so these models tend to have low accuracy. This study examines the features of available models and proposes improved weight estimation model. The database of the existing 50 turbofans with thrust lower than 50kN was developed to compare models with the statistical information, and to update the regression coefficients of the proposed model. Standard deviations and correlation factors of models were determined. Refining of model coefficients was obtained as a result of minimization of a standard deviation value.
