Aerodynamic Hovering Performance of Rigid and Flexible Wing Planform Shapes
Wing geometric parameters govern the aerodynamic performance of insects and micro aerial vehicles. Previous studies of wing shapes have been limited to rigid wings. The aerodynamic hovering performance of rigid and flexible wing shapes for aspect ratio AR = 1.5 is evaluated computationally at the Reynolds number (Re) of 400. The three-dimensional viscous incompressible Navier-Stokes equations a...
متن کاملVortex patterns generated by a heaving flexible plate
We present dye visualizations of the wake behind a flexible plate flow when its leading edge is forced into harmonic heave motion. We show that, when the forcing amplitude is sufficiently large, a reverse Bénard-von Kármán vortex street is formed in the wake, indicative of the production of positive thrust.
متن کاملPerformance Prediction of a Flexible Manufacturing System
The present investigation presents a stochastic model for a flexible manufacturing system consisting of flexible machine, loading/unloading robot and an automated pallethandling device. We consider unreliable flexible manufacturing cell (FMC) wherein machine and robot operate under individual as well as common cause random failures. The pallethandling system is completely reliable. The pallet o...
متن کاملPerformance Optimizing Gust Load Alleviation Control of Flexible Wing Aircraft
This paper details a control design for flexible wing aircraft that attempts to minimize the load induced by gust disturbance. Wing root bending moment is taken as an available measure of gust load and is used in a performance optimizing cost function to determine the load-alleviating control signal. However, both the disturbance signal and system matrices associated with wing root bending mome...
متن کاملWing Shaping Concepts Using Distributed Propulsion
Distributed propulsion and lightweight structures on transport aircraft pose a significant opportunity to meet next generation aircraft requirements including reduced fuel burn/emissions and enhanced takeoff/landing performance. The objective of this research is to conduct multidisciplinary design analysis and optimization to demonstrate a novel concept of flexible wing shaping aircraft using d...
