An accessory drive gearbox for a commercial aircraft was designed to fit below a jet engine compressor case. The gearbox is driven off the engine compressor shaft and drives the electrical generator as well as the engine fuel, oil, and hydraulic pumps.

The main requirements were to provide a detailed schematic layout and analysis of the gear train components, including the shafts and gear stresses, and to reach a targeted RPM and max torque for each of the driven components. These requirements were all met while maintaining a design safety factor of at least 1.15 throughout.

My primary responsibility in this group project involved writing a MATLAB script to parametrically analyze the gear teeth bending and contact stresses using the American Gear Manufacturer's Association (AGMA) Standard. I also assisted in verifying other group members' calculations, 3D modeling, and final rendering of the design.

This was a great experience working in a team environment over an accelerated summer course and provided insight into the level of complexity that's involved with a full system design and analysis.
