Transport Category Airplane Fuselage Master Geometry Parametrical Modeling Method

摘要

The analysis of transport category airplane fuselage design features and master geometry modeling methods showed that the methods should be updated to provide quicker automated editing of the model as well as improvement of its quality and accuracy. Transport category airplane fuselage master geometry parametrical modeling method was developed basing on specification requirements, general view drawing, generalised theoretical drawing and fuselage parameters matrix. The method takes in account main geometrical parameters and allows their variation in wide range with automatic model update for providing required characteristics. Proposed method is verified using data of airplanes made by SC "Antonov". Fuselage parameters influence on its volume and washed surface area was studied. Fuselage master geometry parametrical modeling method implementation in frontend design of passenger airplane for local airlines allowed quick geometrical characteristics determination on early design stage and provide meeting the requirements of specification and aviation regulations.
