  Pitch-Flap Stability of an Articulated Rotor with Fluidic Pitch Links (2016 AHS Technical Meeting on Aeromechanics Design for Vertical Lift conference paper and presentation)• Researched the aeroelastic stability of a medium duty, articulated helicopter with fluidic pitch links• Applied dynamics principles to derive the perturbation equations of motion for a rigid blade with pitch and flap degrees of freedom and an attached fluidic pitch link (4-DOF overall system) in hover and forward flight• Using Matlab, designed a program to determine the stability of the systemo Eigenanalysis techniques were used to determine the stability of the system for a helicopter in hover (constant coefficient A-matrix) while Floquet theory techniques were used for a helicopter in forward flight (periodic terms appear in the A-matrix)o Parallel computing techniques were used to increase the speed of the Matlab simulation in order to perform a significant parametric studyo Created x-y plots, 2-D and 3-D histograms, and contour plots for analysis purposesTesting and Model Verification of a Double Pumper Fluidic Pitch Link• Assumed lumped parameters and linear elemental equations to develop a model for the double pumper fluidic pitch link• Used Autodesk Inventor to modify an existing fluidlastic® isolator, which is used to represent the fluidic pitch link, in order to enable the connections of a newly-designed swappable inertia track and pressure transducers for the fluid chamberso Designed three circuits with varying inertia track length in order to vary location of the first notch frequencyo Designed a fourth circuit with a needle valve in order to vary the resistance of the system and to change the shape and depth of the notch• Developed and executed a test plan using static and dynamic stiffness tests on an MTS single-axis test machine • Compared experimental results to a Matlab simulation to ensure the veracity of the model for frequency-domain and time-domain simulations

• Student Associate in Mechanical Technology and Development

  • Oct 2016 - Nov 2016

  This was a short internship as part of my LORD Corporation Graduate Fellowship to work on the design and testing of a fluidic pitch link for my PhD research project. Additional short trips were also needed to complete the required work. Design: •Used Autodesk Inventor to modify an existing fluidlastic® isolator in order to enable the connections of a newly designed swappable inertia track and pressure transducers for the fluid chambers •Ensured that all of the necessary parts were machined or ordered and that the fluidic pitch link was correctly assembled Testing: •Devised a test plan that consisted of running static and dynamic stiffness tests on an MTS single-axis test machine while recording time, position, force, and the pressures in both chambers for each frequency
