This chapter introduces the building blocks that make up the aeroelastic and manoeuvre/gust load models. The model should adequately represent the aircraft complexity, including control surface and engine behaviour, and generate sufficiently accurate mode shapes. The chapter first defines the mass properties and idealization and then considers the different possible stiffness models and resulting structural models. The aerodynamic models used in loads and aeroelastics calculations are vital in allowing the aeroelastic mechanisms to be explored and sufficiently accurate deformations and load distributions to be estimated. There is a growing interest in performing aeroelastic calculations using coupled computational fluid dynamics (CFD)/structure finite element (FE) models. A non‐linear flight control system (FCS) model is developed for handling the aircraft; it will be coupled with the aircraft dynamic model for a modern commercial aircraft.
