An Assessment of the CFD Effectiveness for Simulating Wing Propeller Aerodynamics
… see a renewed interest in aircraft with multiple propellers. To support conceptual design of these vehicles, one of the major needs is a fast and accurate method for estimating wing aerodynamic characteristics in the presence of multiple propellers. For the method to be effective, it must be easy …

Aerodynamic study of a small, ducted VTOL aerial vehicle
… with mixed results. Concerns regarding duct aerodynamics led to the proposal for further aerodynamic study to investigate effects of inlet lip radius and surface area, diffuser area ratio, blade tip clearance and rotor position on thrust, power and efficiency. This report covers the theory of …

Post stall propeller behavior at low Reynolds numbers
Limited data exists for propeller and wind turbine post stall aerodynamics. Post stall aerodynamics was observed in small propellers at low Reynolds numbers. First, performance data (thrust, power, and efficiency) of set variable pitch propellers was acquired in a wind tunnel. The propellers were 6 …

Regional Transport Aircraft Design using Turbo Electric Distributed Propulsion (TEDiP) System
… interference between the wing and the tractor propeller wake to provide increased lift during takeoff.In the present research, the advantages and disadvantages of integrating a turbo-electric distributed propulsion (TEDiP) system are assessed for a regional transport aircraft (RTA). With near …
