The aerodynamic surfaces (viz. wings) are generally considered to be in steady condition (i.e. time-invariant) and thus the resulting forces and moments are also ‘steady’ (i.e. no change with time). However, this assumption has limitations at various critical flight conditions, such as, during maneuver and gust response analyses the behavior of aerodynamic surfaces under dynamic…

Foundations of CFD
The prerequisites of learning CFD are: 1. Governing conservation equations of fluid dynamics. 2. Navier-Stokes (N-S) equation. 3. Basic heat transfer equation. 4. Programming Skills. (C/C++/MATLAB/Python) Objective: To solve numerically the N-S equation. Discretization: FDM,FVM,FEM Central Difference, Forward Difference, Backward Difference. Exploration of new schemes , extension of new schemes.
Morphing Wings: Bio-inspiration from Birds.
Wing design for aerospace vehicles is a compromise between stability and performance. Depending on the intended flight regime of operation, design parameters for wings are chosen. Thus, the wing for a particular flight condition will not remain optimal in another flight regime. However, birds do not conform to these engineering design laws, as they have…
The Art of Flight
The reason for the noise in aircraft is not only due to the jet engines but also because of the behavior of the air as it travels over the wing and the fuselage surfaces. This is astonishing when we compare this to a bird flying over our head gliding almostsilently. The secret lies in how…
