Journal ArticleDOI
Aerodynamic optimization of helicopter rear fuselage
TL;DR: The demonstrated method can be applied to fuselages of any shape during the initial design phase and is shown that a decrease of fuselage drag around 2.5% is possible without compromising the structure and the functionality of the design.
Journal ArticleDOI
Estimates of hover aerodynamics performance of rotor model
TL;DR: In this paper, the influence of CFD mesh construction peculiarities and mesh parameters on the results was considered, including the rotor polar, loads per unit length, and vortical flow below the rotor disk was also visualized.
Journal ArticleDOI
Computational Fluid Dynamics Modeling of Helicopter Fuselage Drag
TL;DR: In this paper, the authors present aerodynamic analyses of realistic fuselage configurations using computational fluid dynamics using a development model of the Ansat helicopter, and further modifications are introduced to the fuselage model to demonstrate drag reduction via small shape changes.
Journal ArticleDOI
Simulation of Tail Boom Vibrations Using Main Rotor-Fuselage Computational Fluid Dynamics (CFD)
TL;DR: In this paper, fully-resolved rotor-fuselage interactional aerodynamics is used as the forcing term in a model based on the Euler-Bernoulli equation, aiming to simulate helicopter tail-boom vibration.
