The purpose of this course is to expose the engineer/student to different subsystems of aircraft. It will be explained about the construction of aircraft. Importance of aircraft systems and influence of each systems in the duration of flight. This course represents a typical modern civil aircraft. After this course, engineer or student is in a position to have a clear picture on complete overview. The course covers the following topics like.
A. Introduction to aircraft.
B. Basic principles of aircraft.
C. Structures.
D. Fly by wire concept.
E. Landing gear.
F. Auxiliary power unit and engines and other systems.
The finite element method is an approach to solve any complex engineering structures with higher degree of structural redundancy. Students will be more exposed to problems related to aero-structures. This course gives special attention in simulating the structure more realistically using FEM and engineering softwares. In this course the important aspects of structural design are addressed. The course is as follows:
A. Idealization of structure more realistically in finite element modeling.
B. Guiding principles for element selection and boundary conditions.
C. Better understanding of the response of the structure for a given loading scenario.
D. Developing finite element models for analysis of components.
E. Solving fracture mechanics problems using Finite element analysis.
F. Finite element analysis of airframe components like aircraft, rotorcraft and engine etc.
G. Structural analysis methods like linear, non linear using FEM.
H. Finite element analysis of structural joints
I. Postprocessing techniques.
A project work will be given to the student at the end of the course. This will include hands on experience on all the stages of pre & post processing of the structural model. Verification of FEA response of the structure for a given set of loads & boundary conditions with Strength Of Material (SOM) calculations.
