Evaluation of A Counter-Rotating Electric Ducted Fan

Abstract

The research and analysis presented in this study quantifies the benefits of a dual-stage counter-rotating electric ducted fan (EDF) that is optimized for high-speed operations. A thrust increase of 29 percent over a single rotor with the same frontal area was demonstrated. A custom thrust stand was developed to obtain these results and leave in place a capability to test future multi-stage EDF concepts. Commercial off-the-shelf components were modified to accommodate the proposed study. In addition, 3D scanning and reverse engineering techniques to create the necessary CAD models for computations studies were developed, which in turn allows for validation of the proposed EDF performance using three-dimensional fluid modeling software.
