The increasing use of unmanned aerial vehicles and micro air vehicles creates a strong
demand for the accurate aerodynamic performance of small-diameters fixed-pitch …

The performance characteristics of a rotor that is typically used for small unmanned aircraft
were analyzed in a series of wind‐tunnel experiments. Wind‐tunnel measurements were …

Abstract In Computational Fluid Dynamics (CFD) simulations, limited full-scale studies with
ship propellers have been conducted due to the limitation of computational resources and …

This paper presents the design and optimization of a new propeller to use on the MAAT
cruiser airship. The inverse design methodology is based on minimum induced losses and …

Design, wind tunnel test, computational fluid dynamics (CFD) analysis, and flight test data
analysis are conducted for the propeller of EAV‐3, which is a solar‐powered high‐altitude …

The geometry of a propeller is closely related to its aerodynamic performance. One of the
geometric parameters of a propeller is pitch. This parameter determines the distance by …

The propulsion system of High-Altitude Platform Stations or High-Altitude Pseudo-Satellites
(HAPS) is commonly based on propellers. The properties of the atmosphere at those high …

Fan affinity laws are combined with a simple scaling relationship for fan noise to show that
truly significant reductions in propeller noise can be achieved by increasing the propeller …

An unbalanced propeller can affect a quadcopter's performance due to vibration, also
decreasing its thrust's yield. Analyses were conducted to determine the correlation between …

Biologically-inspired flap** wing flight is attractive at low Reynolds numbers and at high
angles of attack, where fixed wing flight performance declines precipitously. While the merits …
