Modern aerospace systems are highly complex and expensive; the US Army is the main procurer of rotorcraft in the world and has not developed a completely new airframe in some time. High development and procurement cost have instead driven the US Army to rely on constant upgrades to its ever aging fleet. These upgrades alter the performance and geometry of the systems dramatically, in order to better optimize the vehicle and aid in the design of new rotorcraft an integrated design tool was developed that enhances the overall system based on certain performance and manufacturing criteria and redesigns the system to the optimal configuration.
The objective of this study is to improve gear design for specific applications through Finite Element Analysis (FEA). A gear web (thin rimmed) is created in gears to improve strength to weight ratio of a given gear. The process, known as excess material removal, is done in this study through HyperWorks OptiStruct’s topology optimization tool.
