Modelling of aerodynamic interference of three-DOF GyroWheel rotor

International Journal of Modelling, Identification and Control, 2018
GyroWheel is an integrated mechanism which provides both attitude control torques and measurements of attitude angular rates for tiny spacecrafts. However, aerodynamic interference is inevitable in the process of ground test which hinders the improvement of the system performance.

Aerodynamic interference during sabot discard

Guidance and Control Conference, 1977
Abstract : An experimental program has been conducted to investigate disturbances to the trajectories of gun-launched, fin-stabilized projectiles during the sabot discard process. Correlated near muzzle and down range measurements of sabot component and projectile motion are acquired using both orthogonal, flash X-rays and a ballistics range.

Aerodynamic Interference Issues in Aircraft Directional Control

Journal of Aerospace Engineering, 2015
This 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 of Cascade Blades in Synchronized Oscillation

Journal of Applied Mechanics, 1955
Abstract 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.

Study of aerodynamical interference for a wind turbine

International Communications in Heat and Mass Transfer, 2010
Abstract A two-dimensional interference model of upwind wind turbine, based on NREL Phase VI, was simulated by an available Navier–Stokes solver under parallel process. The simulation domain was divided into a stationary tower domain and a sliding blade domain with varying geometric factors, including blade chord to tower diameter ratio and tower ...

Computational modeling of multibody aerodynamic interference

Advances in Engineering Software, 1998
Abstract 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 ...

Aerodynamic Interference of a Large and a Small Aircraft.

Journal of Aircraft, 2004
The influence of wake from a leading aircraft, Boeing 757, on a following aircraft, Cessna 750 Citation X, is investigated using the unsteady vortex lattice method. The effect of the wakes from both wings and each other is considered and the new position of the wakes from both aircraft calculated. As the midspan of the Cessna wing approaches the Boeing

An experimental study of highway aerodynamic interferences

Journal of Wind Engineering and Industrial Aerodynamics, 1984
Abstract Energy and material considerations today point in the direction of smaller and lighter vehicles. With further reductions in the weight of vehicles, aerodynamic forces emerge as a major factor in energy and stability calculations. In the present study the aerodynamic interference forces between two vehicles (passenger cars and articulated ...
