Coupled Aerodynamic/Dynamic Modeling and Optimization of an Avian Inspired Flight Bhavsar, Vivek Nareshkumar; 0000-0003-4003-4566 Chowdhury, Souma Mechanical and Aerospace Engineering fluid mechanics aerospace engineering biomechanics M.S. This study develops the early-stage models for studying and optimizing bird-like flapping wing flight with the objective of power consumption of aircraft flapping frequency and amplitudes. CFD analysis on a flat plate airfoil is performed to study the transient flapping wing flight under prescribed forward velocity where the flow conditions are in the range of Re: O(10^{4}-10^{5}). The aerodynamic model is to be coupled with a flight dynamics model and later optimized with particle swarm optimization(PSO). This optimization constrained with the allowable band in the Z-direction and minimum X-direction position. The dynamic model needs unknown, which obtained with surrogate model techniques. The propulsive efficiency is then calculated to compare it with the bird's power consumption. 2018-10-26T02:57:36Z 2018-10-26T02:57:36Z 2018 2018-08-16 15:14:20 Text Thesis http://hdl.handle.net/10477/78654 eng Users of works found in University at Buffalo Institutional Repository (UBIR) are responsible for identifying and contacting the copyright owner for permission to reuse.
