UKRI-2649 NSTF Direct Field Acoustic Noise Facility

This procurement describes the activities to be executed and deliverables required by STFC in relation to the definition, supply, and commissioning of a Direct Field Acoustic Noise (DFAN) system. This system will to be used to test satellites and large sub-assemblies in the National Satellite Test Facility. An acoustic test system is required for the NSTF to permit the testing of any spacecraft up to 7000kg and to fit inside a 4.6m fairing to the levels and durations required by all the currently available launch systems. To achieve this, RAL Space intends to purchase a system using the latest commercially available DFAN technology to provide a uniform diffuse sound field to test their customer's satellites and large sub-assemblies. The use of DFAN technology gives the opportunity to reconfigure the system, add capacity when needed, and be open to future control upgrades and more flight representative test methods.
