چکیده

This paper presents a time-accurate procedure for computing unsteady aerodynamic forces on wings with a full-span oscillating control surface by using sheared grids. In this procedure, the flow is computed by solving the unsteady Reynolds-Averaged Navier-Stokes (RANS) equations in conjunction with the one-equation Spalart-Allmaras turbulence model. A module to model control surface oscillations is embedded into a general purpose RANS solver. Unsteady pressures and forces are validated with experimental data for wall-to-wall mounted and finite-tip wings with full span control surfaces. The effect of Mach number on unsteady aerodynamic loads is investigated for the transonic flow regime.

A Modular Approach to Model Oscillating Control Surfaces using Navier-Stokes Equations

A modular procedure is presented to simulate moving control surfaces within an overset grid environment using the Navier-Stokes equations. Gaps are modeled by locally shearing the wing grids instead of using separate grids to model gaps. Grid movements for control surfaces are defined through a separate module, which is driven by an external grid generation tool. Results are demonstrated for a ...

Computational Investigation of Wings with Miniature Trailing Edge Control Surfaces

Miniature trailing edge effectors (MiTEs) are small flaps (typically 1% to 5% chord) actuated with deflection angles near 90 degrees. The small size, combined with little required power and good control authority enables the device to be used for both high bandwidth control and conventional attitude control. Numerous experiments and computational simulations have been conducted for two dimensio...

Scientific Flow Field Simulation of Cruciform Missiles Through the Thin Layer Navier Stokes Equations

The thin-layer Navier-Stokes equations are solved for two complete missile configurations on an IBM 3090-200 vectro-facility supercomputer. The conservation form of the three-dimensional equations, written in generalized coordinates, are finite differenced and solved on a body-fitted curvilinear grid system developed in conjunction with the flowfield solver. The numerical procedure is based on ...

Efficient Flapping Flight Using Flexible Wings Oscillating at Resonance

We use fully-coupled three-dimensional computer simulations to examine aerodynamics of elastic wings oscillating at resonance. Wings are modeled as planar elastic plates plunging sinusoidally at a low Reynolds number. The wings are tilted from horizontal, thereby generating asymmetric flow patterns and non-zero net aerodynamic forces. Our simulations reveal that resonance oscillations of elasti...
