Structural Health Monitoring Of Composite Helicopter Rotor Blades
(Indian Institute of Science, 2007-04-18)
Helicopter rotor system operates in a highly dynamic and unsteady aerodynamic environment leading to severe vibratory loads on the rotor system. Repeated exposure to these severe loading conditions can induce damage in the ...
Wavelet Based Spectral Finite Elements For Wave Propagation Analysis In Isotropic, Composite And Nano-Composite Structures
(2009-04-02)
Wave propagation is a common phenomenon in aircraft structures resulting from high velocity transient loadings like bird hit, gust etc. Apart from understanding the behavior of structures under such loading, wave propagation ...
Numerical Simulations Of Axisymmetric Near Wakes At High Reynolds Numbers
(2009-03-13)
The flow past the needle of a Pelton turbine injector is an axisymmetric wake embedded in a round jet. The wake does not fully relax to yield a uniform velocity jet due to the short distance
between ...
A Neural Network Approach To Rotorcraft Parameter Estimation
(2009-07-03)
The present work focuses on the system identification method of aerodynamic parameter estimation which is used to calculate the stability and control derivatives required for aircraft flight mechanics. A new rotorcraft ...
Rotationally Invariant Kinetic Upwind Method (KUMARI)
(2009-03-11)
In the quest for a high fidelity numerical scheme for CFD it is necessary to satisfy demands on accuracy, conservation, positivity and upwinding. Recently the requirement of rotational invariance has been added to this ...
