National Aerospace Laboratories (NAL), Bangalore is a constituent of the Council of Scientific and Industrial Research of India (CSIR). Originally started as National Aeronautical Laboratory, it was renamed National Aerospace Laboratories to reflect its major involvement in the Indian space programme, its multidisciplinary activities and it’s global positioning.

Over the last five decades NAL has successfully contributed to the growth in India of aerospace activities in particular within defence and space sectors. NAL has made significant contributions to a large number of aerospace programmes such as civil and military aircraft, and space and engine development programmes.

NAL’s sophisticated test facilities boast among others full scale fatigue and acoustic testing facilities – actively supported by Brüel & Kjær since the early days. For some 40 years now, Brüel & Kjær has been supplying NAL with the complete measurement chain of sound and vibration equipment – from transducers and conditioners, to noise generators, spectrum shapers and analyzers. Currently, the1100 m3 Acoustic Test Facility extensively uses Brüel & Kjær microphones, conditioning and PULSE systems as part of their acoustic environment testing programme for satellites and satellite subsystems.
