Total energy compensation for the vario in the GPS-Logger 2!

The TEK Düse is the ideal complement for our GPS-Logger 2. This has über a TEK connection to the vario and allows together with the TEK Düse a vario experience as with the man-carrying gliders.
Our TEK Düse works on the principle of the "Braunschweiger Düse". The man-carrying aviation uses this type of construction today almost exclusively. The construction is more complex than the simple curved Nicks Düse, but is unsurpassed in compensation and also provides perfect results in model flight. D
he Düse is made entirely of stainless steel and hard gelötet. The Düsenkopf is held in the Maßstab 1:2. This sounds bigger than it is, as the original dampers are very small. The Düse seems correctly dimensioned on models of virtually any size.
. The 2.5 mm diameter tube is about 240 mm long and 40 mm high in the angled version for installation in the vertical stabilizer. In the original this length is about 750 mm, so our Düse has the correct length for 1:3 he model. For smaller models the tube can be shortened a little, for larger ones it could be lengthened and stiffened with a carbon fiber tube. The straight version for installation on the fuselage back is about 120 mm long.

What is überhaupt TEK?

TEK means simplified the fading of the "Knüppelthermik" by Berücksichtichtigung of the ride of the model. This is achieved by connecting a TEK Düse to the variosensor.
For slow models flying at a constant speed, the simple vario without TEK is often sufficient. Here the errors due to controlled heights are not so large and you can see the thermals through the vario already well. The cleaner you fly and the smaller the speed changes are, the better the vario works without TEK Düse.
However, with dynamic models or even with less than perfect flying style, vario outputs always occur that do not show the true climb and sink of the model, but only a controlled speed or altitude change, the Knüppelthermik. In fact, the only thing of interest in the thermal search is whether you are flying in a rising, falling or neutral air mass. As far as possible, regardless of how the aircraft is currently moving.
Exactly this behavior is achieved by using a TEK Düse on the variometer. This nozzle generates a negative pressure that is dependent on the airspeed and thus simulates a climb as the airspeed increases, compensating for the loss of altitude. So you press on, the altitude decreases, and the vario without TEK would indicate sink. The TEK Düse compensates for this by displaying climb for the speed that is increasing as it is decreasing. The conversion of height (potential energy) into velocity (kinetic energy) is therefore no longer incorrectly interpreted as sinking or climbing with the TEK Düse.
In the ideal case, with full compensation, the vario always shows the current intrinsic sink of the aircraft in absolutely calm air. Of course, this is not a constant value, but depends on the speed, lift and other factors.

The connection between TEK Düse and GPS-Logger 2 is made with the separately available Düsen holder, Order No. 2785, and the hoses contained therein.
