AE2403 VIBRATIONS AND ELEMENTS OF AEROELASTICITY L T P C
3 0 0 3
OBJECTIVE
To study the dynamic behaviour of different aircraft components and the interaction
among the aerodynamic, elastic and inertia forces
UNIT I BASIC NOTIONS 8
Simple harmonic motion – Terminologies – Newton’s Law – D’ Alembert’s principle –
Energy Methods
UNIT II SINGLE DEGREE OF FREEDOM SYSTEMS 12
Free vibrations – Damped vibrations – Forced Vibrations, with and without damping –
support excitation – Vibration measuring instruments.
UNIT III MULTI DEGREES OF FREEDOM SYSTEMS 10
Two degrees of freedom systems – Static and Dynamic couplings vibration absorber-
Principal co- ordinates, Principal modes and orthogonal condition – Eigen value problems.
65
Hamilton’s principle- Lagrangean equation and application – Vibration of elastic bodies-
Vibration of strings- Longitudinal, Lateral and Torsional vibrations.
UNIT IV APPROXIMATE METHODS 5
Rayleigh’s and Holzer Methods to find natural frequencies.
UNIT V ELEMENTS OF AEROELASTICITY 10
Concepts – Coupling – Aero elastic instabilities and their prevention – Basic ideas on wing
divergence, loss and reversal of aileron control – Flutter and its prevention.
