The new maritime laboratory at Hochschule Emden/Leer is built around a new towing tank by Edinburgh Designs.

The tank is 33m long and 3m wide and features 8×0.7m hinge depth force feedback flaps in a movable box module.

The Towing machine is capable of 5m/s and high acceleration rates.

The new laboratory is design to falilitate the validation of their state of the art CFD research.

Mini Flap Paddle for the NTNU Karmsund Flume

Back in the 1980′s, Edunburgh Universities Professor Stephen Salter installed a single flap wavemaker for Professor Johannes Falnes at NTNU. It fits that Edinburgh Designs would be the company to replace this machine almost 40 years later.
The new machine is a single dry back force feedback flap paddle with a set of 8 wave gauges.

Glass Sided Compact 3D Tank at Strathclyde University

Full Electronic Upgrade at DGA, France

The 24 paddle machine was installed in 1998 and was the first multi paddle, large flap Edinburgh Designs machine.

Having worked well for over 20 years, the servo amplifiers and digital controllers are now obsolete, and spares are hard to come by.

The machine is now like new and can be seen in action in the following video:

After 20 years, it was a good time for a full electronic upgrade.
The mechanical side of the machine only required some minor renewal works.
