A METHOD OF MODELLING AT LEAST A PART OF A GAS TURBINE ENGINE

摘要

A method of modelling at least a part of a gas turbine engine, the method comprising: preparing a model of at least a part of the gas turbine engine using a data structure including: a first set of data entities representing geometrical shapes of physical features; and a second set of data entities representing geometrical shapes of aerodynamic boundaries, the second set of data entities being used to preserve aerodynamic design intent during preparation of the model.
