Computational Predictions of the Performance Wright 'Bent End' Propellers by National Aeronautics and Space Administration (NASA) PDF Summary

Book Description: Computational analysis of two 1911 Wright brothers 'Bent End' wooden propeller reproductions have been performed and compared with experimental test results from the Langley Full Scale Wind Tunnel. The purpose of the analysis was to check the consistency of the experimental results and to validate the reliability of the tests. This report is one part of the project on the propeller performance research of the Wright 'Bent End' propellers, intend to document the Wright brothers' pioneering propeller design contributions. Two computer codes were used in the computational predictions. The FLO-MG Navier-Stokes code is a CFD (Computational Fluid Dynamics) code based on the Navier-Stokes Equations. It is mainly used to compute the lift coefficient and the drag coefficient at specified angles of attack at different radii. Those calculated data are the intermediate results of the computation and a part of the necessary input for the Propeller Design Analysis Code (based on Adkins and Libeck method), which is a propeller design code used to compute the propeller thrust coefficient, the propeller power coefficient and the propeller propulsive efficiency.Wang, Xiang-Yu and Ash, Robert L. and Bobbitt, Percy J. and Prior, Edwin (Technical Monitor)Langley Research CenterPROPELLER EFFICIENCY; PROPELLER BLADES; COMPUTATIONAL FLUID DYNAMICS; WIND TUNNEL TESTS; NAVIER-STOKES EQUATION; COMPUTERIZED SIMULATION; APPLICATIONS PROGRAMS (COMPUTERS); LIFT; AERODYNAMIC DRAG
