Numerical Investigation of Stage Separation Control of Tandem Hypersonic Vehicles Based on Lateral Jet

Aerospace
The stage separation of hypersonic vehicles is critically challenged by severe aerodynamic interference, which induces significant attitude deviations and jeopardizes subsequent flight missions.

Travelling-wave similarity solutions for an unsteady shear-stress-driven dry patch in a flowing film [PDF]

, 2013
We investigate unsteady flow of a thin film of Newtonian fluid around a symmetric slender dry patch moving with constant velocity on an inclined planar substrate, the flow being driven by a prescribed constant shear stress at the free surface of the film

Geometry requirements for unsteady aerodynamics in aeroelastic analysis and design [PDF]

Aircraft geometry requirements for unsteady aerodynamic computations are discussed and differences between requirements for steady and unsteady flow are emphasized within the framework of a general potential-flow aerodynamic formulation.

Numerical solutions of the linearized Euler equations for unsteady vortical flows around lifting airfoils [PDF]

A linearized unsteady aerodynamic analysis is presented for unsteady, subsonic vortical flows around lifting airfoils. The analysis fully accounts for the distortion effects of the nonuniform mean flow on the imposed vortical disturbances.

An overview of a Lagrangian method for analysis of animal wake dynamics [PDF]

, 2008
The fluid dynamic analysis of animal wakes is becoming increasingly popular in studies of animal swimming and flying, due in part to the development of quantitative flow visualization techniques such as digital particle imaging velocimetry (DPIV).

Unsteady transonic flow in cascades [PDF]

There is a need for methods to predict the unsteady air loads associated with flutter of turbomachinery blading at transonic speeds. The results of such an analysis in which the steady relative flow approaching a cascade of thin airfoils is assumed to be
