Module Title:Aircraft Structures Fundamentals
Language of Instruction:English
Credits: 5
NFQ Level:6
Module Delivered In 3 programme(s)
Teaching & Learning Strategies: The module will be delivered using lectures, tutorials and laboratory sessions to illustrate the concepts under study
Module Aim: To provide the student with: • the skills to analyse the internal effects of forces applied to the members in an aircraft structure, as evidenced by the stresses and deformations resulting. • a foundation for subsequent modules in the area of Aircraft Structural Mechanics, with particular reference to Aircraft structures
Learning Outcomes
On successful completion of this module the learner should be able to:
LO1 Demonstrate an understanding of basic aircraft structural principles including the behaviour of structural elements under load.
LO2 Demonstrate an understanding of the principal theories of aircraft structural behaviour by performing calculations of stress, strain and prediction of failure, involving the concepts of direct stress, direct strain, modulus of elasticity, Poisson’s ratio, volumetric & area strain.
LO3 Analyse the behaviour of composite materials subject to loading.
LO4 Apply and solve formulae to determine the shear force and bending moment distributions resulting from the loading of a structural element such as a simply-supported beam or cantilever and to determine the resulting stress induced as a function of cross-sectional second moment of area.
LO5 Apply and solve formulae to determine the forces in the individual members of a loaded truss or framework in an aircraft.
LO6 Contribute effectively, as an individual and as part of a group, to the planning and realization of investigations in a laboratory environment into the behaviour of structural materials in service.
