Fairey Swordfish W5856 Update

Exciting news from the Navy Wings Heritage Hangar where the brand new valves for the Swordfish W5856 have arrived and the Royal Navy Heritage Flight engineers are working hard to put the engine back together.

In May, during a routine inspection  of the aircraft’s Pegasus 30 engine an unusual problem was discovered with the engine cylinder valves that required specialist investigation.  Further investigation showed, that new valves were required to be made and the Trust sourced the valves from bespoke valve makers G&S Valves Ltd 

The valves have a sodium infill to allow maximum cooling, as one of the hardest working parts of the engine the valves need to cool down from 800 degrees down to 200 degrees all along the length of the valve. The manufacturing of the valves is very complicated with thirty separate processes needed to make the specialist valves.  G&S Valves are the only company with the sodium infill machine to be able to make the valves for the Swordfish and we would like to thank Andy Grenside and the team for all their hard work.

The specialist valves cost over £15,000 to make and the charity would like to thank all our supporters for raising money to keep important, heritage naval aircraft in the skies. The Swordfish has successfully completed the first ground run with the new valves and The oldest surviving Swordfish  W5856 in the world will be joining the Sea Fury T20 in the air very soon.
