21. On Aircraft Conceptual Design : A Framework for Knowledge Based Engineering and Design Optimization
Abstract : This thesis presents a design framework where analytical tools are linked together and operated from an efficient system level interface. The application field is aircraft conceptual design. Particular attention has been paid to CAD system integration and design optimization.Aircraft design is an inherently multidisciplinary process.

22. Model based aircraft design : high angle of attack aerodynamics and weight estimation methods
Abstract : This thesis addresses modelling of high angle of attack aerodynamic characteristics and weight estimation for highly maneuverable aircraft during conceptual design. In order to allow configuration selection with sufficient confidence, especially with unconventional configurations, high angle of attack aerodynamic prediction and weight estimations methods need to be improved.

23. Affect as a Component of Perceived Sound and Vibration Quality in Aircraft
Abstract : The concept of product sound quality is becoming an integral component of product development and design. The research presented in this thesis test the notion that affective reactions (i.e. positive-negative feelings) are a major determinant of perceived sound quality. READ MORE

25. Modelling of unsteady aerodynamics for aircraft design
Abstract : This thesis present a simple mathematical prediction model for high angles of attack aerodynamics, including dynamic effects over delta wings, and an extension to full configuration. The model presented is intended for application in conceptual design and is extended to parameters identifications in preliminary design with validation against experimental data. READ MORE
