A unique leak detection system in spaceships.


In space, a huge number of tiny meteors and space debris pose a threat to spacecraft. A little bit, a couple of millimeters in diameter can, for example, spread aluminum airframe of the International Space Station, which is spinning over our heads at an altitude of 220 miles (354 kilometers).

The new device, sensor, developed at the University of Iowa, will reveal the leak in the hull of a spaceship. Repair the damage is much easier than figuring out where it is. Spacecraft are full of all kinds of electronics, computers, engines and research equipment, the noise of which does not allow astronauts to hear the distinctive capabilities for leaks by the sound of a whistle and find the leak.

Developed device "listens" hull of a ship and finds leaks by vibration, which causes the air flowing away into space through the casing. This sensor, a width of a few centimeters, consists of 64 detectors that detect the sources of vibration throughout the body of the spacecraft. Each of the detectors senses vibrations at different times. The difference in the readings and processed by the computer calculates the direction and location of the leak.

At the gathering of information from the sensors and the determination of the leak takes about a minute (by the way, with the help of ultrasonic devices, which now uses NASA to search for leaks, such a search would have taken weeks!). For cost and reliability of such a detector exceeds all existing analogues. In the near future, these devices will be used on the ISS and other space vehicles. We will tell you the exciting news from the horse’s mouth.
