Rebuilding a piece of aeronautical history
TFC were pleased to assist in supplying a small volume of Spirolox® double-turn retaining rings when called upon to help by the de Havilland Mosquito Museum based at Salisbury Hall in Hatfield, Hertfordshire.
The de Havilland Mosquito Fighter Bomber was a British multi-role combat aircraft with a two-man crew that served with the RAF and other Allied countries during WW2 and with many other air forces around the world in the post war era. Only a few aircraft survive of the 7,000 built, mainly because the wooden construction has been unable to readily withstand the rigours of an external environment over so many years.
The specific role played by TFC was in the supply of double-turn Spirolox® retaining rings used to ensure the hub nut, housed in the de Havilland hydromatic propellor assembly, cannot become unscrewed. Unlike a conventional retaining ring or circlip that has a gap-end profile, Spirolox® rings are made from a continuous coil of round-edge flat wire that is coiled on edge to form a full 360º support shoulder when fitted in a mating shaft or housing groove. Designed to conform to standard Imperial and DIN groove standards, these innovative products are readily available from stock in a wide range of materials to suit diameters from 6mm to in excess of 2,000mm.
TFC are exhibiting at the prestigious Farnborough International Air Show being held 14th - 20th July and, if you are planning a visit, we would be pleased to welcome you to our stand FT3, Hall 4. On display are the extensive range of space saving Smalley Crest-to-Crest® flat wire wave springs and the Spirolox® edge wound retaining rings used in the Mosquito application.
