TCD Students in Microgravity
|Last January four TP students from TCD
proposed an experiment to ESA to fly on the Student Parabolic Flight
Campaign. It was accepted.
|In June we put our experiment togethor in the TCD Physics workshop|
|The experiment flew on the 26th and 27th of
July. It was a success.
From a steady horizontal flight, the aircraft gradually pulls up its nose and starts climbing at an angle of approximately 45 degrees. This "injection" phase lasts for about 20 seconds, during which the aircraft experiences an acceleration of around 1.8 times the gravity level at the surface of the Earth, i.e. 1.8 g. The engine thrust is then reduced to the minimum required to compensate for air-drag, and the aircraft then follows a free-fall ballistic trajectory, i.e. a parabola, lasting approximately 20 seconds, during which weightlessness is achieved. At the end of this period, the aircraft must pull out of the parabolic arc, a manoeuvre which gives rise to another 20 second period of 1.8 g on the aircraft, after which it returns to normal level flight attitude.
formed a soap film in a cubic wire frame and then injected liquid into the
Plateau Borders (film intersections) during microgravity. This allowed
them to observe the transition from a dry film configuration to a wet
are the first microgravity experiments of there kind.
