Defence
Performance, Reliability, Monitoring
Brüel & Kjær supplies the aerospace and defence industry with tools and systems to measure and validate noise and vibration parameters to ensure reliability and high performance of military equipment, instrumentation and vehicles while withstanding often extreme conditions.
In addition, we specialise in systems that actively monitor and report noise and vibration under operations, in the workplace and the surrounding environment, to ensure stealth, help implement nuisance abatement and improvement programmes.
Standards Compliance
Whether turnkey solutions or dual-use application needs, Brüel & Kjær provides the defence sector with solutions that comply with common industry standards, such as MIL-810, NATO STANAG 1136 and AS/EN9100.
Brüel & Kjær continuously evaluates policies and applications against the requirements of International Traffic in Arms Regulations (ITAR) and Export Administration Regulations (EAR). Brüel & Kjær recognizes the offset obligations of aerospace and defence companies and we work closely with the Danish Enterprise and Construction Authority to assist foreign companies in fulfilling the obligations entered in their Industrial Co-operation Contracts.
Occupational Health and Safety
Injuries, complaints and litigation are just as relevant concerns for the defence industry as anywhere else. With Brüel & Kjær instruments, a military organisation can identify where, in high-risk areas, a person is allowed to work and for how long he may work. Specialised measurements and modelling can also help determine what protection, damping and design elements are needed to improve the work environment.
Ensuring structural performance
Defence applications demand high structural performance under extreme environments. Although load cases can be simulated through virtual modelling, these models must be validated through testing of prototypes. To this end, Brüel & Kjær provides an integrated Structural Test Suite.
Product durability
Military personnel have to be confident that highly dangerous material is stored safely and transported without affecting its performance, or that onboard components and systems hold up against extreme conditions. To achieve this, they often need to carry out shock, vibration, temperature, altitude and humidity testing. Brüel & Kjær has a range of solutions that ensure that anything from the smallest of triggers to the largest of missiles can be properly designed for safe storage, usage and transport.
Identifying Noise Sources
Noise has a major impact on many aspects of a military vehicle – from crew health and acoustic discretion to environmental considerations in a non-combat climate. Identifying a particular noise source can be a challenge in itself and the extreme conditions under which military vehicles operate magnify this challenge considerably. Brüel & Kjær offers a wide range of acoustic customer-oriented solutions, ranging from simple sound level measurements to the most sophisticated microphone array systems using advanced algorithms and hardware.
Ensuring Acoustic Stealth
As acoustic detection and identification techniques evolve, so must acoustic stealth strategies. To maintain acoustic discretion, all of a vessel’s or air vehicle’s noise sources must be considered. Brüel & Kjær’s extensive experience with underwater and aircraft acoustics and shock response properties combined with underwater testing solutions can be used in application-specific tasks, from investigating, analysing and identifying noise sources to validating advanced designs.
Maintaining Operational Integrity
If there is a problem with an engine, the airvehicle does not fly. Preventative maintenance and manufacturer-specified checks prolong the health of engines. With the right equipment, they improve early problem detection, which is a must for maximising the up-time of an aircraft....
