27 de may. de 2024 · aircrafts offer high forward flight speeds and efficiency, but they encounter stability issues during tilting transitions, control challenges, and safety risks. Fixed-wing hybrid multi-rotor aircrafts combine the benefits of multi-rotor and tilt-rotor aircraft designs, offering good controllability and relatively higher flight ...
30 de may. de 2024 · This paper investigates the aeroacoustic characteristics of 2-bladed propellers during the edgewise forward flight and descent phases of eVTOL aircraft through experimental and numerical.
27 de may. de 2024 · During vertical flight, eight propellers provide lift for the eVTOL aircraft, with the aircraft’s position and attitude controlled by varying propeller speeds. Upon reaching a safe altitude, the motor of the propulsive wing is activated during the forward flight, providing lift and propulsion.
15 de may. de 2024 · In this paper, we numerically studied the effect of stroke deviation on the aerodynamic performance of the three-dimensional flapping wing in forward flight at a low Reynolds number. Six deviation motion patterns with different stroke deviation amplitudes were investigated.
30 de may. de 2024 · Large-Eddy Simulation and Broadband Acoustic Prediction of a Helicopter Rotor in Forward Flight. A compressible large-eddy simulation (LES) is performed on an helicopter rotor in forward flight in order to compare with wind-tunnel measurements and previous similar simulations in hover.
11 de may. de 2024 · The hybrid high-speed compound helicopter has three flight modes: the low-speed hover mode, the transition forward-flight mode, and the high-speed forward-flight mode. The control strategy is different for different flight modes.
21 de may. de 2024 · The present study introduces a novel adjustable method for practically alleviating the dynamic stall on helicopter blade section in forward flight conditions to improve its aerodynamic performance in different operational conditions.
