Principle Stress Analysis Engineer
Current-IPT Lead of two $1 million Future Advanced Rotorcraft Drive System (FARDS) research projects. Lead the technical team responsible for the design, manufacture and test of a composite-steel helicopter mast and a composite-steel sprag clutch. Coordinated the development and test activities with multiple departments and external subcontractors. Developed and tracked the project schedules. Supported all briefings with the Army customer and prepare monthly technical and project reports. -Performed static and fatigue FEA analysis on transmission cases, gears, drive shafts, masts and clutches for the drive systems group at Bell Helicopter. -Created a non linear model of the planetary system for the FARDS transmission. Iterated the model to obtain a geometry that minimized the fatigue and static stresses while decreasing the weight of the assembly.-Created a model of the FARDS transmission case. Analysis was used by the designed to determine low stress areas where material could be removed and high stress areas that required modifications. Worked with the designer to iterate the design/analysis to minimize the transmission’s weight.-Designed and analyzed a composite-steel mast. Iterated the FEA model of to design a geometry that reduced the mast’s weight and the stress levels.-Designed and analyzed the fatigue test fixture for the composite-steel mast.-Designed and analyzed a composite-steel sprag clutch. Performed the FEA analysis of the clutch to determine a geometry that reduced weight the stress levels.-Performed static and fatigue analysis of transmission cases to determine damage limits. Analysis required nonlinear models with plasticity to correctly describe the load paths.-Performed a transient heat transfer analysis of the FARDS transmission to determine different configurations that decreased the temperatures in the transmission.-Conducted training sessions for less experience engineers on ANSYS and engineering topics.
