Flight dynamics analysis of a small tandem helicopter considering aerodynamic interference
Proceedings of the Institution of Mechanical Engineers, Part G: Journal of Aerospace Engineering, 2022The interference calculation is essential to the flight dynamic analysis especially for multi-rotors configurations. To analyze the flight dynamic characteristics of a small tandem helicopter precisely, a vortex method is utilized to obtain the ...

Aerodynamic Interference Issues in Aircraft Directional Control
Journal of Aerospace Engineering, 2015This work investigates the aerodynamic interference among airplane components caused by rudder deflection for a typical turboprop aircraft geometry through the computational fluid dynamics technique. At no sideslip, an airplane is in symmetric flight conditions.

Aerodynamic interference and unsteady loads for a hovering intermeshing rotor
The Physics of Fluids, 2022Synchropters are increasingly applied for precision work in placing suspended loads due to its unique flying characteristics. However, the special intermeshing rotor structural helicopter easily introduces rotor-and-rotor interference, leading to ...

Aerodynamic interference in tall rectangular buildings
Journal of Wind Engineering and Industrial Aerodynamics, 1992Abstract An aerolastic model of a typical rectangular multistoreyed building has been tested in a boundary layer wind tunnel together with a rigid interfering building model placed at a number of locations upstream as well as downstream of the aeroelastic model.

Computational modeling of multibody aerodynamic interference
Advances in Engineering Software, 1998Abstract The research effort has focused on the development and application of a versatile overset grid numerical technique to solve multibody aerodynamic problems. The developed numerical capability has been used successfully to determine the aerodynamics and provide critical information on the design and development of two multibody systems: sabot ...

2021 Aerial Robotic Systems Physically Interacting with the Environment (AIRPHARO), 2021
Inspection and maintenance tasks are increasingly being carried out by multi-rotor platforms in order to avoid certain risks being taken by humans. In this way, it is necessary to have a good knowledge of the aerodynamic effects that occur when tasks are

Aerodynamic interference of vertical axis wind turbines
Journal of Propulsion and Power, 1990The laminar flowfield and performance of clusters of two-dimensional vertical axis wind turbines are analyzed by idealizing the rotors as momentum sources. The flowfield dominated by the pressure field of the operating turbines is determined by solving the incompressible Navier-Stokes equations and mutual interference is observed to be elliptic in ...

Aerodynamic Interference of Cascade Blades in Synchronized Oscillation
Journal of Applied Mechanics, 1955Abstract The failure of a compressor is sometimes due to flutter of the blades. Essentially, this problem is equivalent to a cascade in oscillation. The present analysis is to find the aerodynamic load on cascade in synchronized harmonic oscillations, pitching, and flapping. Conformal mapping is used.

Wing-Tip-To-Wing-Tip Aerodynamic Interference
41st Aerospace Sciences Meeting and Exhibit, 2003The aerodynamic interaction of finite wings flying in very close proximity is investigated experimentally. Docked wings are also examined. Tests were carried out in a water tunnel and Particle Image Velocimetry (PIV) was employed to generate velocity data along Trefftz planes.
