RISTip Clearance Investigation of a Ducted Fan Used in VTOL Unmanned Aerial Vehicles—Part II: Novel Treatments Via Computational Design and Their Experimental Verification
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Ducted fan based vertical lift systems are excellent candidates to be in the group of the next generation vertical lift vehicles, with many potential applications in general aviation and military missions. Although ducted ...
Tip Clearance Investigation of a Ducted Fan Used in VTOL Unmanned Aerial Vehicles—Part I: Baseline Experiments and Computational Validation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Ducted fans that are popular choices in vertical takeoff and landing (VTOL) unmanned aerial vehicles (UAV) offer a higher static thrust/power ratio for a given diameter than open propellers. Although ducted fans provide ...
Factors Influencing Computational Predictability of Aerodynamic Losses in a Turbine Nozzle Guide Vane Flow
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper deals with the computational predictability of aerodynamic losses in a turbine nozzle guide vane (NGV) flow. The paper shows that threedimensional (3D) computations of ReynoldsAveraged Navier Stokes (RANS) ...
