	Flight physics Probing the mysteries of flight To be able to fly is one of mankind's oldest dreams. In the course of the last century it became a reality, and today flying is a matter of course. We go on vacation by plane, and flying kites or sailplanes and paragliding are leisure activities.

A modular wind tunnel

For over 100 years wind tunnels have been one of the tools used by fluid mechanics engineers. Aircraft, automobiles, trains, sportsmen and even bridges have been investigated with the help of wind tunnels. There were various reasons for such studies. The origins of air turbulence are of special interest, and air resistance also plays an important role, for example in the fuel consumption of cars. At DLR_School_Lab Göttingen you yourselves can put together a wind tunnel and learn about the functions and effects of each component in fluid flow.

Detecting tornados

Do we have tornados here too? What is a tornado, anyway?

Tornados not only exist in the USA; they can arise here in Germany as well. Observations confirm that in southern Lower Saxony there are about five tornados every ten years which leave behind a destructive track. That's reason enough for the DLR_School_Lab Göttingen to investigate this phenomenon. With the help of a "tornado machine" you can yourselves produce a whirlwind and become acquainted in experiments with the interesting conditions that favor the emergence and destructive impact of tornados.

	Flow physics Seeing the invisible Why can an airplane fly? How does the air behave that flows around automobiles, trains, buildings or aircraft, and what influence does it have? To be able to answer such questions, scientists first of all had to develop various methods for making flows in water or in air visible.

Helicopters

We encounter helicopters in daily life and often wonder: how does a helicopter stay up in the air and how is it even able to remain in one place? At DLR_School_Lab Göttingen you can learn the basic principles of helicopter flight. And also get acquainted with the IPCT measurement technique, which makes visible the deformation of rotor blades.

	Resonance frequencies The wind as musician Why are the vibrating strings of an aeolian harp interesting to scientists? Wind not only makes musical instrument strings vibrate. It can also cause bridges, high voltage transmission lines, towers and automobile antennas to vibrate violently, ending up in a "resonance catastrophe" causing their destruction.

	Measurement technology Videographs of ultrafast processes In research and technology one is often confronted with processes which occur at such high speeds that they can neither be seen with the naked eye nor recorded with traditional methods.

	A miniature drop tower When astronauts float around in space the reason is weightlessness, or better, microgravity. But can that be experienced on Earth as well? At DLR_School_Lab Göttingen you can conduct microgravity experiments with a miniature drop tower and observe the behavior of objects in free fall. The entire text is only available in German.

	Flows around objects Light brings clarity Everything that flies makes use of flow. That’s why someone who constructs aircraft has to completely understand flow to assure that a plane will fly safely and efficiently. Since flow generally cannot be seen, it has to be made visible. Scientists use various methods to do this; one of them involves a layer of soap film.
