Aerodynamic interference in tall rectangular buildings

Journal of Wind Engineering and Industrial Aerodynamics, 1992
Abstract 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.

Aerodynamic Interference for Hypersonic Missiles at Low Angle of Attack

Journal of Spacecraft and Rockets, 1998
An Euler code is used to predict the e owe eld over a hypersonic missile and to determine the carryover factors KW(B), e n liftinthepresenceofthebody,and KB(W),liftproducedby thebody in thepresenceofthee ns. Themissile is assumed to have cruciform, delta e ns in the + orientation and an aspect ratio of 1.529.

Aerodynamic interference and unsteady loads for a hovering intermeshing rotor

Physics of Fluids, 2022
Synchropters are increasingly applied for precision work in placing suspended loads due to their unique flying characteristics. However, the special intermeshing rotor structural helicopter easily introduces rotor-and-rotor interference, leading to unsteady aerodynamic loads on the rotor blades in mission flight.

Studies in Transonic Aerodynamic Interference.

1977
Abstract : The work reported herein represents the first phase of a study of transonic aerodynamic interference problems as applicable to store-wing-body combinations without the pylon. The nonlifting and lifting transonic integral equations in the velocity components in the field of the flow were obtained.

Wing-Tip-To-Wing-Tip Aerodynamic Interference

41st Aerospace Sciences Meeting and Exhibit, 2003
The 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.

Aerodynamic Interference Between Stores

1992
Abstract : Five tasks were initiated to study the aerodynamic interference between stores and aircraft. Both viscous and inviscid calculations were made. Steady state interference calculations matched well with experimental results and with other computational results.

Aerodynamic interference of vertical axis wind turbines

Journal of Propulsion and Power, 1990
The 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 ...

Fin-interference effects on the aerodynamics of a swept-fin missile

13th Applied Aerodynamics Conference, 1995
The flow about the complete Hypersonic Applied Research Technology (HART) missile is simulated for inviscid, laminar, and turbulent conditions and Mach numbers from 2 to 6. An explicit, second-orderaccurate, flux-difference-splitting algorithm is implemented and en~ployed to solve the Navier-Stokes equations.

Aerodynamic interference for supersonic low-aspect-ratio missiles

Journal of Spacecraft and Rockets, 1995
and K for low-aspect-ratio, cruciform wingbodies with clipped delta fins for Mach numbers from 3 to 4 and angles of attack up to 20 deg. The ratios of fin span to body radius (S/R) range from 1.3 to 2, so that aspect ratios vary from 0.05 to 4 and taper ratios vary from 0 to 0.975. Euler results compare well with experimental data.

Aerodynamic interference of airfoils in a subsonic unsteady flow

Fluid Dynamics, 1966
Integral equations [1] are used to study the case of unsteady gas flow about a system consisting of a finite number of airfoils. As an example, the aerodynamic forces acting on the airfoils of a biplane in an unsteady subsonic gas flow are calculated. In this very simple case, a special study is made of the acoustic resonance effect reported previously
