Definition of Thermal acoustic imaging
Thermal acoustic imaging (TAI) is an active thermographic inspection process developed by Pratt and Whitney (P&W) in 2005. TAI is a nondestructive testing (NDT) method to detect internal and external cracking of hollow-core metallic turbofan engine fan blades. Considered proprietary by P&W, TAI is performed to inspect the PW4000 112-inch (2,800 mm) diameter fan blades in an enclosed air-conditioned room within the engine manufacturer's overhaul and repair facility in East Hartford, Connecticut.
