Weightless space
An inside view of the refitted Airbus A310 aircraft. Although the aircraft can weigh up to 157 tonnes, skilled pilots angle its nose 50° upwards to create brief periods of weightlessness. At the top of each curve, the forces on the passengers and objects inside cancel each other out, causing everything to float in weightlessness.
During the climb and pulling out of the descent, the occupants endure almost twice normal gravity. A person weighing 80 kg on Earth will feel as if they weighed 160 kg for around 20 seconds.
Conducting hands-on experiments in weightlessness and hypergravity is enticing for researchers in fields as varied as biology, physics, medicine and applied sciences.
To turn it into a parabolic science aircraft most seats were removed to provide as much space as possible inside, while padded walls provide a soft landing for the researchers – the changes in ‘gravity’ can be hard to handle. Extra monitoring stations have been installed for a technician to monitor the aircraft system’s as it is pushed to its limits – this is no transatlantic cruise.
