Title:
Gradient-Based Optimization of a Turboprop Rotor System with Constraints on Stresses and Natural Frequencies 
Abstract:
This work presents ongoing investigations of optimization of rotor systems in aero engines. A non-linear constrained optimization problem of shaft mass minimization is considered. Design variables are inner radius and wall thickness of shaft sections. Constraints are imposed on torsional and equivalent stresses, natural frequencies, and design variables. A gradient projection method is applied to solve the sizing optimization problem. Predictions of stresses and natural frequencies are obtained...    »
