Development and application for modeling a comprehensive simulation for helicopter ship landing

Rotorcraft ship landing represents a complex task in which the pilots has to track a moving ship deck while keeping the vehicle stable in the presence of ship airwake. My PhD thesis focuses on developing a comprehensive simulation capability for the helicopter ship landing problem. The capability should include all relevant components: a high fidelity helicopter flight dynamics model, a model for wind-over-deck, a ground effect model, and a robust control system.

Numerical Investigation of The Modal Properties of a Feather Shaft Inspired Parametric Finite Element Model

The central shaft of bird feathers is studied extensively by researchers in different contexts, but yet, very little is known about its dynamic or modal behavior in relation to morphology. It has been shown that the cross sectional shape of avian feather shafts changes progressively from circular, at the base or calamus, to rectangular down the rachis. The modal properties of this circular-to-rectangular transition section are investigated using a parametric finite element model developed in ANSYS APDL.

Experimental modal analysis of a macro-fiber composite based morphing trailing edge concept

Investigated the vibration response of a camber morphing trailing edge concept introduced by Dr. Alex Pankonien as a function of morphing or actuation level, and aerodynamic loading. The trailing edge consists of two Macro Fiber Composite (MFC) patches that are joined to each other at one end and connected to a compliant flexure mechanism on other. With an appropriate voltage input, the compliant flexure system allows one of the patches to extend while the other contracts.
