SST Cold Spray Technology keeping historical aircraft airworthy - Chipmunk engine restoration
Author: Dr. Ph. D. P. Eng. Julio Villafuerte
Cold spray is a solid-state metal consolidation process that is used to dimensionally restore aircraft components made of materials that are highly sensitive to elevated process temperatures. In this case study, the leaky engine casing of a Chipmunk vintage aircraft was successfully restored, for the first time, using the SST cold spray technology. (SST is an abreviation for Supersonic Spray Technologies which is also a Division of CenterLine Windsor Ltd.) This study shows a step by step restoration procedure, which was then certified as a new repair procedure by Transport Canada, the Canadian organization responsible for safe air transportation policies and programs.
