New heights for plastic bearings

New heights for plastic bearings A 67 year-old Indian aviator, Dr Vijaypat Singhania, recently flew to 69,852ft and set a new world altitude record for a hot air balloon. UK expert Flying Pictures Space managed the project from design concept to manufacture, pilot training, launch and recovery. Igus injection moulded polymer bearings were used in the balloon's pressurised capsule, which was vital to reach these heights. A conventional hot air balloon has a large fabric valve in the top. This parachute valve is normally opened by the pilot pulling a string when he requires the balloon to descend. This mechanism was designed into the pressurised capsule by building two hand wheels either side of the pilot's seat. These connected to a drum on the outside of the capsule via a shaft mounted in Iglidur polymer plain bearings from Igus. At 70,000ft, the temperature was expected to be -60 degrees C, and temperatures of +38 degrees C were expected in the shade on the ground. These temperatures were no problem for the high performance polymer bearings.
