NASA tames flames in space with SoFIE

At present, security in the face fire It is a topic that is often overlooked. Thus, various studies have been conducted with the aim of excluding some flammable materials in the design of certain instruments. Until recently, researchers conducted experiments aimed at better understanding the behavior of flame extraterrestrial. Ultimately, data from the experiments could help improve fire safety on Earth.

In fact, the experiments were conducted aboard a safe compound specially equipped. In addition, this project is called sophie (Solid Fuel Ignition and Extinction) will be launched aboard Northrop Grumman’s 17th cargo resupply mission to the International Space Station.

In addition, NASA (National Aeronautics and Space Administration) was the initiator of this large-scale study. On the other hand, Paul Vercola researcher on the SoFIE project at Glenn Search NASA Center in Cleveland, participated in the research.

The critical importance of SoFIE

Indeed, current safety measures make it possible to better control fires a land than before. Logically, these procedures were applied to astronauts’ suits. But unfortunately, fire behaves differently in space. Gravity changes And the air flow It can change the way it spreads and make it harder to put down.

As a result, it was necessary to create a special project to study in the best possible conditions The behave flame in space. Thus, the Solid Fuel Ignition and Extinction (SoFIE) project was conceived.

“Understanding how flames spread and how certain materials ignite in different environments is critical to the safety of future astronauts.”

In addition, the complex’s unique controlled gravity environment allows scientists to study The true nature of a single flame Nor A change by gravity. The data collected can then be applied to mathematical models that predict how these materials will burn in space environments.

Well organized experience

To conduct this study, the researchers decided to divide the experiment into five main stages. First, these researchers will focus on diffusion flame Stable and unstable using thin materials for spaceflight. Then they will look at the spread of fire thick surfaces And the petition.

By following these two steps, these scholars will proceed to study Limit From growth And the’Firefighting. In addition, they will perform a material ignition test and suppression test. Finally, the latter will do the work interconnected relationship Between the study of flammability of spacecraft materials and test data for flammability by gravity.
