Brüel & Kjær (now HBK) delivered their HVME (Hull Vibration Monitoring Equipment) solution to BAE Systems Submarine Solutions. The purpose is to assist ship staff in maintaining a low noise signature by monitoring and analysing hull vibration and hydrodynamic noise.
The HVME system will be deployed on HMS Audacious, the fourth boat in the UK Royal Navy's Astute-class, nuclear-powered attack submarine construction programme.
The Brüel & Kjær (now HBK) HVME system will provide monitoring and analysis facilities of structure-borne noise generated in the submarine. The purpose is to assist ship staff to maintain a low noise signature by monitoring and analysing both hull vibration and hydrodynamic noise.
The PULSETM modular and scalable platform, with over 12,000 systems sold worldwide, includes the flagship LAN-XI acquisition unit. The ‘hand-sized’ network-based LAN-XI modules provide a distributed architecture to give installation flexibility and drastically reduce amounts of sensor cabling.
Brüel & Kjær (now HBK) underwater acoustics products and solutions range from sensors and exterior/interior noise source identification and noise mapping systems, through complete acoustic ranging and noise self-monitoring solutions.
BAE Systems Submarine Solutions based in Barrow-in-Furness North-west England, is a wholly owned subsidiary of BAE Systems, responsible for the development and production of submarines.
The company is constructing the Astute-class submarine, a new generation nuclear attack submarine (SSN) for the Royal Navy, the first of which was launched on 8 June 2007.
LAN-XI is a modular data acquisition system and analyzer platform providing you with a flexible front end capable of delivering over 1000 channels in a portable DAQ system. Both LAN-XI and LAN-XI Light are designed to deliver unrivalled dynamic input range for capturing sound and vibration data in a wide range of demanding measurement applications.
As a world-class naval engineering business, BAE Systems has been working with the UK Ministry of Defence (MOD) to design a new class of frigate: the Type 26 Frigate. To ensure the acoustic stealth of its combat ship, BAE Systems needed a world-class self-noise monitoring system: HBK's PULSE scalable platform.
Dedicated electroacoustic device testing software with applications and profiles for analysis of specific products including microphones, speakers and headsets.
A key requirement for combat ships and submarines, Self-noise Monitoring System (SNMS) help to minimize the noise and vibration of a vessel and its on-board systems. HBK has decades of experience in permanently installed SNMS to reliably identify and analyse noise sources.
Acoustic detection and identification techniques continuously become more advanced and sophisticated. As they evolve, so must acoustic stealth strategies.
