In-orbit experiment with an attitude control algorithm for ANS based on modern control principles

The existing fine attitude system of the Astronomical Netherlands Satellite was designed on the basis of conventional digital control techniques. The possibility of a more advanced approach is presented in this report. As an example, an alternative control algorithm for the scan mode has been developed with the use of state estimation and state...

Calculation of vibration modes and resonance frequencies of the Northrop NF-5

The component mode technique is used to calculate resonance frequencies and vibration modes of the Northrop NF-5 structure. The results of the calculations are compared with those of a ground vibration test.

Low speed windtunnel measurements on a two-dimensional flapped wing model using tunnel wall boundary layer control at the wing-wall junctions

An investigation on a two-dimensional wing model with a double-slotted trailing edge flap is described where tunnel wall boundeo'y layer control by blowing was applied to prevent premature flow separations at the junctions between the model and the tunnel walls. From the results it is concluded that tunnel wall boundary layer control at the wall...
