Aerospace Vehicles Design

Aerospace Vehicles Design (EAS411)


EAS411 Aerospace Vehicles Design introduce knowledge and skills to develop a conceptual and preliminary design of a fixed wing manned or unmanned air vehicle based on design requirements. Fundamental knowledge learnt in EAS301 Aerospace Dynamics and EAS309 Flight Dynamics and Control forms the guiding principles and theoretical background of this course. The first part of the topics is structured to approximate the sequence for design layout. The second part of the topics concerns design analysis including aerodynamics, flight performance, stability and control, and cost estimate. Typical design practice, considerations and proven rules of thumb in air vehicle design are introduced and trained through a design project. Applications of open source software and implementations of numerical calculation are integrated into the hands-on design training.
