The challenge in sonar housing design is balancing physical durability with acoustic transparency. A housing that is structurally sound but acoustically opaque is useless. AIMRSE utilizes advanced finite element analysis (FEA) to simulate acoustic transmission losses. We specialize in Rho-C Matched Polyurethanes and thin-wall Titanium windows that minimize impedance mismatch at the water interface.
For active sonar systems (projectors), our housings are engineered to manage the violent mechanical stresses of high-power piezoelectric oscillation without delamination or fatigue failure. We employ vacuum-degassed potting compounds to ensure a void-free encapsulant, eliminating the risk of internal corona discharge or cavitation damage during high-duty cycle operations.
Fig.1 Multi-layer acoustic window design minimizes signal attenuation and reflection.
Window materials are selected to match the acoustic impedance of seawater (approx. 1.5 MRayls), reducing signal reflection and ghosting.
Optional C63000 Marine Bronze or Cupronickel construction naturally inhibits marine growth, essential for long-term deployed observatories.
Hard-anodized surfaces and elastomeric coatings protect the housing face from erosion caused by high-intensity cavitation bubbles.
Sonar arrays often mix noble metals (piezoelectric elements, silver ceramics) with structural housings, creating a perfect recipe for galvanic corrosion. AIMRSE solves this through material isolation and careful alloy selection. We offer three primary material tiers depending on the deployment environment.
| Property | Titanium (Gr 5) | Marine Bronze (C63000) | Stainless (316L) | AIMRSE Acoustic PU |
|---|---|---|---|---|
| Density (kg/m³) | 4,430 | 7,450 | 8,000 | 1,050 |
| Sound Speed (m/s) | 6,070 | 4,700 | 5,790 | 1,550 (Match to Water) |
| Acoustic Impedance (MRayls) | 27.0 | 35.0 | 45.7 | 1.6 |
| Magnetic Permeability | < 1.001 (Non-Mag) | < 1.05 | ~1.02 (Work hardens) | 1.0 |
| Corrosion Resistance | Immune (in Seawater) | Excellent (Bio-fouling Resistant) | Pitting Risk (Requires Anodes) | Immune (Non-Metallic) |

We specialize in non-cylindrical geometries. From conformal flank arrays to streamlined towfish bodies, our 5-axis CNC machining centers can produce complex Titanium and Bronze housings that minimize hydrodynamic drag and flow noise.
Every sonar housing undergoes rigorous testing to ensure it meets both mechanical and acoustic specifications. Our testing protocols include:
Our quality management system is certified to ISO 9001:2015. For sonar housings, we offer material traceability according to EN 10204 3.1. Every housing undergoes non-destructive testing (NDT) and Hyperbaric Pressure Testing to its rated depth before shipment.
Standards: ASTM, ASME, MIL-SPEC, DNV-GL Compliant.
We provide full technical support for sensor integration, including:
Our housings are electrically isolated and grounded to eliminate electromagnetic interference (EMI), crucial for sensitive passive hydrophones.
We can reverse-engineer legacy housings for discontinued sonar systems, offering modern material upgrades for aging fleets.
Proprietary epoxy coating systems for Aluminum housings that survive 2,000+ hours of salt spray testing (ASTM B117).
Integrated heat-sink fins machined directly into the housing body to dissipate heat from high-duty cycle transmitters.
Your sensor data is only as good as the housing protecting it. Don't let corrosion or acoustic impedance compromise your mission. Whether you are building a new benthic lander or retrofitting a fleet of AUVs, AIMRSE provides the material expertise and manufacturing precision to ensure crystal-clear acoustic performance.
Need a specific Rho-C match for your transducer frequency? Our engineers can customize acoustic window layers for your specific mission profile.
Note: Our Laboratory Reagents and Chemicals are for research and industrial testing use only. However, our Subsea and Oil & Gas hardware components are fully rated for operational field deployment.
