Experimental Study of Vortex Shapes behind a Wing Equipped with Different Winglets
Volume 3, Issue 1 , March 2006, Pages 1-20
Abstract
An extensive experimental study is conducted to examine effects of different winglet-shapes and orientations on the vortex behind a wing, static surface pressure over the wing, and wing wake of a swept wing at various angles of attack. Four types of winglets, spiroid (forward and aft), blended, and winggrid ... Read MoreNumerical Simulation of Flow Past Oscillating Airfoil Using Oscillation of Flow Boundary Condition
Volume 3, Issue 1 , March 2006, Pages 17-21
Abstract
The present study is devoted to an approximate modeling for numerical simulation of flows past oscillating airfoils. In this study, it is shown that the harmonic oscillating objects can be studied by simple numerical codes that are not able to solve moving grids. Instead of using moving grid for the ...

Volume 3, Issue 1 , March 2006, Pages 23-30
Abstract
In this paper application of a simulation algorithm for dynamic and nonlinear analysis of a specific liquid propellant engine is presented. The mathematical model of the engine includes a set of nonlinear algebraic equations which is coupled with a set of time varying differential equations. In contrast ...

Volume 3, Issue 1 , March 2006, Pages 31-42
Abstract
The contribution of this paper to the space transportation system field is to select promising Reusable Launch Vehicle (RLV) concepts by using a formal evaluation procedure. The vehicle system is divided into design features. Every design feature can have alternative characteristics. All combinations ... Read MoreNonlinear Optimal Control Techniques Applied to a Launch Vehicle Autopilot
Volume 3, Issue 1 , March 2006, Pages 43-49
Abstract
This paper presents an application of the nonlinear optimal control techniques to the design of launch vehicle autopilots. The optimal control is given by the solution to the Hamilton-Jacobi-Bellman (HJB) equation, which in this case cannot be solved explicity. A method based upon Successive Galerkin ...
