Dassault performs Falcon 8X business jet’s noise certification test
July 6, 2016
Dassault Aviation has confirmed the completion of a noise certification test for its newly unveiled Falcon 8X business jet.
The news comes from an article published on the Executive and VIP Aviation International (EVA) website, on 4th July 2016. Dassault completed the test “using an acoustic data acquisition and analysis system from Brüel & Kjær.”
The testing of the exterior aircraft noise is a regulatory requirement in the aviation industry. According to the news article published on the EVA website:
“The tests establish certified aircraft Effective Perceived Noise Levels (EPNLs) for each of the flight conditions: approach, flyover and sideline.”
The Testing Process
The testing process is an advanced technological endeavour and involves the use of remote data processing parameters. This is conducted through the use of Brüel & Kjær’s proprietary system. The operational infrastructure of Brüel & Kjær’s system comprises three data acquisition portals. These are then appropriately positioned in the test area. In addition, the three stations designed to work in synchrony with GPS and convey communication signals through Wi-Fi connections. The whole idea revolves around having the three remote locations measure and record the data. This picks up on the exterior noise levels of an aircraft while recording the entire activity using a webcam.
The data acquisition and processing procedure is usually monitored and adjusted from a central station. The EVA website article explains that the:
“Central monitoring station controls the data acquisition, uploads data, interfaces to flight-track data and layered weather data, and calculates results.”
The Brüel & Kjær system is also integrated with automated computational modules. These then facilitate the determination of the noise levels of an aircraft.
The advanced functional features of the Brüel & Kjær system serve to reassure prospective buyers and users of the Falcon 8X business jet. By proving that the aircraft’s regulatory credentials have been acquired accordingly, this should attract new buyers too. In conclusion, acquiring the certification is a positive move for Dassault Aviation.
