In collaboration with Boeing, the world's largest aircraft maker, DTU Mechanical Engineering has copied the interior of a Boeing 767. The purpose of this is to perform experiments regarding the indoor environment in aircrafts by exposing subjects to conditions which correspond to the climate in the cabin during a flight. One example is the ventilation: "The experiments show that the majority prefer a relatively high level of ventilation. Dryness is perceived as less annoying than the existence of chemicals and heavy air, "says Geo Clausen, Associate Professor at DTU Mechanical Engineering.
The project has been running for a couple of years, and DTU and Boeing have now made a larger consortium that works with the indoor environment in aircrafts under the American Federal Aviation Administration. "There is great international interest in our results. There are not many places in the world where you have the opportunity to make such controlled trials with human subjects. In this way we have got a head start, "says Geo Clausen.
