After Airbus modified the A330 to create the military version, they needed to update the aircraft’s noise certification so it could still use civilian airports, where noise restrictions apply.
The military version of Airbus’s A330 passenger jet needs to use civilian airports, where noise restrictions apply. After converting the A330 into the military A330 MRTT, aerodynamic changes required new measurements of noise at approach, to update the noise certification. With the support of Brüel & Kjær, Spain’s Instituto Nacional Técnica Aeroespacial (INTA) conducted the measurements and analysis required.
As testing windows are short and fly-over testing expensive, INTA needed to perform noisecertification measurements on the Airbus A330 MRTT on a tight schedule. INTA needed to capture highly accurate data to European Aviation Safety Agency (EASA) certification standards, in just one measurement.
INTA successfully gathered and processed the data to the standards and methods specified by EASA, and International Civil Aviation Organization (ICAO). They used PULSE data acquisition and analysis systems and microphones from Brüel & Kjær, whose staff assisted INTA personnel during the whole certification process.
The A330 MRTT is now one more successful Airbus Group aircraft fulfilling the civil certification rules of EASA. Consequently, the A330 MRTT not only has the capabilities of a military aircraft, but also the potential to operate in civil airports in peacetime roles, such as international aid operations.
The National Institute of Aerospace Technology (INTA) is a public research body, a non-profit organization specializing in aeronautic and space research and technological development. The institute is located in Torrejón de Ardoz, Madrid, and provides technical assessment to administration authorities in the aerospace field. Its activities include R&D activities of defence interest, R&D activities in the civilian sector, and activities such as testing, experimentation, certifying and technical assistance.
INTA has an environmental laboratory LIMA (Laboratorio de Impacto Ambiental). The INTA-LIMA engineers are renowned for their background in aeroand vibroacoustics and INTA’s laboratory has its own quality management system covering both procedures and calibration according to ISO 70354.
