Total Energy Compensation for the MicroVario!

The TEK nozzle is the ideal complement for the MicroVario. This has a TEK connection on the vario and allows together with the TEK nozzle a vario experience like the man-carrying gliders.

Especially because of the pendulum behavior of the glider system, you will be able to find and center the thermals much faster by using the TEK nozzle. Misinterpretations are eliminated and one reduces the time flying through downwind fields.

In cooperation with the MicroVario, it is even possible to measure the TAS, i.e. the true airspeed with respect to the air. Thus, the nominal speed theory can also be applied and one can fly either in the area of least sink or best glide.

Since 80% of RC Para pilots fly in flatland, the use of the MicroVario and the TEK nozzle greatly enhances the thermal flying experience.

The TEK nozzle works on the principle of the "Brunswick nozzle". Today, man-carrying aviation uses this design almost exclusively. While the design is more complex than the simple curved Nicks nozzle, it is unsurpassed in compensation and delivers perfect results even in model flight.

The nozzle is made entirely of stainless steel and is hard soldered.

The 2.5 mm diameter tube is approximately 240 mm long and 40 mm high for the angled version for installation in the vertical stabilizer.

The straight version for installation on the back of the fuselage is about 120 mm long.

What is TEK anyway?

TEK simply means the suppression of "stick thermals" by taking the model's flight into account. This is achieved by connecting a TEK nozzle to the variosensor.

For slow models flying at constant speed, the simple vario without TEK is often sufficient. Here the errors due to controlled altitude changes are not so great and you can already see the thermals well through the vario. The cleaner you fly and the smaller the speed changes are, the better the vario without TEK nozzle works. But just because the speed changes vary with the RC paraglider due to the pendulum principle, it makes sense to fly with TEK.

However, if the flying style is not perfect, there will always be vario outputs that do not show the true climb and sink of the model, but only a controlled speed or altitude change, the "stick thermals" or pendulum of the pilot. In fact, however, the only thing of interest when searching for thermals is whether you are flying in rising, falling or neutral air mass - as independently as possible of how the aircraft is currently moving.

Exactly this behavior is achieved by using a TEK nozzle on the variometer. This nozzle generates a negative pressure dependent on the airspeed and thus simulates a climb with increasing airspeed which compensates for the loss of altitude. So you press on, the altitude decreases and the vario without TEK would indicate sink. The TEK nozzle compensates for this by indicating climb for the increasing speed when pressing on. The conversion of altitude (potential energy) into velocity (kinetic energy) is therefore no longer incorrectly interpreted as sinking or climbing with the TEK nozzle.

Ideally, with full compensation, the vario will always show the current intrinsic sink of the model in absolutely still air. Of course, this is not a constant value, but depends on speed, lift and other factors.

The connection between TEK nozzle and MicroVario is made with the separately available nozzle holder and the hoses included there.
