A method for applying linear optimal control theory to the design of a regulator for a flexible- aircraft

This report deals with determining a hypothetic control system which provides improved rigid body and structural mode damping of a flexible aircraft in order to improve the riding qualities and to minimize the wing bending moment during flights in turbulence. The equations of motion used in the computations are related to a high' performance...

An ALGOL-program for the calculation of incompressible three-dimensional turbulent boundary layers

A computer program has been prepared for the calculation of turbulent boundary layer development, based on a 3-D version of the turbulent energy method. The method is briefly discussed. The computer program is described in detail. The present program is restricted to developable surfaces.

Axisymmetric liquid sloshing under low-g conditions: numerical simulations method (-reference manual-)

A mathematical model is presented for the description of axisymmetric three-dimensional transient flow of a viscous liquid in a partially filled cylindrical container under low gravity conditions. The mathematical model consists of the Navier-Stokes equations with either no-slip condition at the solid boundaries, and with the continuity of...

PROCRU simulation results compared with Metro II in-flight ILS approach data

The PROCRU (Procedure Oriented Crew) model has been developed for the analysis and modeling of flight crew procedures during an ILS approach. The model's specific capability concerns the generation of "timelines" of the necessary actions to be carried out by each crew member during the approach. Besides, also the corresponding timelines for...
