Noise protection

"There will be a day when humans are fighting noise just like cholera and pest." (Robert Koch)
It is already known for some time that noise can damage or even completely destroy our hearing capabilities. This experience was gathered a long time ago from military, where boisterous sounds occured on a regular basis due to gun fire. In the course of time the expression however changed and noise occured everywhere: at military, factories, on the road and at home.

	Flight simulator The first flying lesson! "The invention of a flight device means nothing; manufacturing is more important; but the most decisive thing is flying it!" At DLR_School_Lab Braunschweig you can find out if Ferdinand Ferber was right with his statement or not. The entire text is only available in German.

	Ultrasonic testing On the tracks of what's hidden from view You've probably heard about ultrasonic tests during a visit to the doctor sometime. Using this method a doctor can look inside your body and, for example, identify tissue or bone damage. This technology was originally developed to rapidly and precisely locate submarines during World War I. The entire text is only available in German.

Piezo strips

Piezo ... what?

In 1880 Jacques and Pierre Curie discovered piezoelectricity. The name comes from the Greek word "piezo" ("pressure"). The two scientists exerted mechanical pressure on a tourmaline crystal and noted a measurable electrical voltage on the surface caused by the resulting deformation. They successfully conducted this experiment also using other crystals like quartz, topaz and potassium sodium tartrate (Rochelle salt).

	Airflow investigations in a wind tunnel Much ado about nothing? Aerodynamics can offer three methods of investigation for determining how new airplanes, automobiles or high-speed trains will actually behave in the air, on roads or rails: free flight or in situ experiments, numerical simulation with supercomputers, and wind tunnel tests.

Driver assistance systems

Tracking down stress

Most accidents are not caused by technical failure connected with the car, but by human error on the part of the driver. The main causes are lack of concentration, a lapse in attention, or distraction. For this reason, DLR researchers in Braunschweig are developing driver assistance systems that can give a warning if there is a risk of an accident happening, thereby making traffic even safer.

Air traffic controller station

Just like an air traffic controller in the tower

Maybe you have been on a flight yourself. The plane is loaded, you and the other passengers board, the plane is backed up and then rolls toward the take-off runway. The pilot gives gas, the plane rises and flies into the heavens ... but who gave the commands for all this activity? And can the pilot himself decide each time which particular route to use to get to the plane's destination? What happens when the plane approaches the airport where it is to land and there are other planes wanting to do the same thing? Who decides the order of landing?

What's the connection between Archimedes and helicopters?

The eminent Greek physicist and mathematician Archimedes (287-212 BC) made an assertion over 2,000 years ago which Leonardo da Vinci (1452-1519 AD) took up much later: "A body submerged or floating in a liquid or gas is buoyed up by a force equal to the weight of the displaced fluid." Leonardo da Vinci concluded that air had to have a certain density before it could generate lift. That gave him a decisive idea: a spiral-shaped surface cycling at high speed around a vertical mast should be capable of lifting loads and holding them up in the air ...

Testing model aircraft

"The only thing dangerous about flying is the earth." (Wilbur Wright)

The ability to leave the earth's surface and fly through the air has long fascinated mankind. Otto Lilienthal was one of the first to realize this dream: he completed over 1,000 successful flight tests by sailing down from a hill using self-made wings. His experiments marked a milestone in aviation. You can carry out your own test flight in this experiment, using small model airplanes.

Rail safety technology

A logical path through the daily train routine

With tne invention of the steam engine and its subsequent further evolution into a steam locomotive by the British engineer Richard Trevithick in 1804 the path was cleared for the development of today's trains. The German rail network is over 30,000 kilometers long and one of the densest worldwide. And although rail traffic increases more and more, the train is one of Germany's safest means of transportation. How can that be?
