CWCD-1000/1010 Sonic Analyzer with CH-47A/B Helicopter Capability
Abstract
The purpose of the work encompassed in the report was (1) to fabricate an automated diagnostic sonic analyzer, (2) to design and fabricate a CH-47A/B helicopter plug-in module with both T55 engine and CH-47A/B helicopter power train components capability, and (3) to design and fabricate an auxiliary microphone switch box. The methods employed in achieving this work consisted of (1) analyzing mechanical data to determine the frequencies of the rotating components, (2) performing a microphone survey and locking frequency investigation, (3) analyzing the acoustical data to develop spectral familiarity and to establish initial analyzer programming and system compatibility, and (4) conducting a field application program utilizing the automated sonic analyzer to correlate analyzer indications with the mechanical condition of the rotating components and to establish analyzer limits.
