Bruel & Kjar to supply Pratt & Whitney Static Engine Noise Test system
Brüel & Kjær is to supply Pratt & Whitney with a Static Engine Certification Test (SECT) System.
The system will perform all tasks needed for static engine noise certification and development testing. The Brüel & Kjær SECT System follows the measurement requirements and procedures set forth by the industry noise certification standards FAR 36 and ICAO Annex 16, SAE ARP 1846 A and the ARP 866A.
The system is based on Brüel & Kjær’s standard, commercial-off-the-shelf (COTS) products. The SECT System employs the B&K PULSE data acquisition and analysis (overall and 1/3rdoctave) system.
It acquires all the relevant noise and weather data needed to generate certificated noise levels and corrects this data to standard reference conditions.
The system provides a dedicated streamlined workflow to ensure that all required tasks and operations are performed with maximum reliability and efficiency.
