Schwarmverhalten von Steinschüttungen in Wasser

Bulk rock dumping in water for underwater structures bears the risk of grain size segregation. Due to their higher weight, large rocks drop faster than finer material. This can lead to vertical grain size segregation within the dumped resulting structure with the large rocks at the bottom and -sorted by size- the smaller fractions on top. The...

Die Gestalt von natürlichen Steinen und ihr Fallverhalten in Wasser

Research at IWAWI of TU Berlin focuses on rock placement in coastal engineering and port construction. During research work it was found that objective and descriptive shape classification of rocks was needed. The introduced method utilizes three independent parameters: size referred to by volume, shape according to Zingg and roundness according...

Untersuchungen zum Fallverhalten würfelförmiger Einzelkörper in Wasser

The underwater fall of cubes (as reference bodies for sharp edged quarry rock material) of different sizes and densities has . been examined. The experimental study has been carried out by using a shaft (diameter: 5 m) filled with water. Due to rotary motion (Magnus' effect), the trajectories of such cubes deviate from vertical lines. The...

Some Aspects of the Design of a "Fly-By-Wire" Flying Control System for a Supersonic V/STOL Fighter Aircraft

The College of Aeronautics adopts a pragmatic approach to the teaching of aircraft design. Students will only be awarded an MSc degree if they have the ability to produce workable, realistic designs in which all of the major problems have been addressed. This ability is assessed by means of annual group projects in which relevant aircraft types...
