Availability: InStock

Engine mount struts are engineered to support the engine’s static weight while absorbing dynamic loads from thrust, vibration, and flight maneuvers. Their structural integrity relies on maintaining axial stiffness while offering controlled flexibility to manage multi-directional vibrations.

Material Specification

Alloy Steel (AISI 4140), Aluminum 7075-T6, or Titanium 6Al-4V (for weight-critical applications)

Mounting Point Configuration (Engine Side)

Flanged (4-6 bolt pattern), Clevis/Yoke (SAE J429), or Spherical Bearing (M12–M24)

Mounting Point Configuration (Chassis Side)

Mounting Point Configuration (Chassis Side) h-to-Connect (PTC, 4mm–25mm)

Overall Length

300mm – 1,200mm (Custom lengths ±2mm tolerance)

Adjustability

Threaded Turnbuckle (±25mm), Slotted Holes (±10mm), or Fixed Length

Product Description

Frigate’s mount struts feature optimized load paths that evenly distribute forces across all mounting points. This design minimizes localized stress concentrations and helps prevent fatigue cracking in adjacent structural components, ensuring long-term reliability under demanding operating conditions.

Load Capacity

Tensile – 50–200 kN, Compressive – 75–250 kN (FEA-validated)

Stiffness/Deflection Limits

≤1.5mm deflection @ max load, Natural frequency >50 Hz (Avoids resonance)

Corrosion Resistance/Coating

Zinc-Nickel Plating (Steel), Hard Anodizing (Aluminum), Passivation (Titanium)

Bushing Bore Tolerances & Finish

H7 tolerance (±0.018mm), Ra 1.6 µm finish, Oil-impregnated bronze bushings optional

Certification Standards

ISO 9001, SAE J267, DIN 1480, MIL-STD-1312 (Load testing)

Technical Advantages

Engine Mount Struts experience torsional, axial, and lateral vibrations across variable frequency spectrums, often overlapping structural resonance ranges. Improper damping can lead to resonance amplification, causing damage to frame joints and misalignment of rotating assemblies. Engineered with custom-tuned elastomeric interfaces or integrated metallic dampers, the struts attenuate broadband vibration energy while preserving the mechanical stiffness required for structural rigidity. Dynamic stiffness and loss factor curves are matched to engine frequency profiles to optimize vibration suppression.

Mounting zones near propulsion units are subject to rapid thermal cycling, often ranging from -55°C during cold start to above 250°C during sustained operation. Materials used in engine mount Struts are selected based on their low coefficient of thermal expansion mismatch with adjacent engine and frame components, ensuring dimensional stability. All structural elements are validated for thermal fatigue resistance, creep deformation limits, and resistance to thermally-induced stress relaxation under continuous duty cycles.

Industry Applications

Aerospace Propulsion System Isolation

Used to isolate turbofan or turboprop engine vibrations from airframe, maintaining structural integrity and alignment under dynamic thrust loads.

Military Ground Vehicle Powertrain Support

Supports heavy diesel engine blocks in combat vehicles, minimizing chassis stress from torsional vibration and off-road shock loading conditions.

Marine Diesel Engine Suspension

Dampens multi-directional engine movement in ship hulls, preventing misalignment of propulsion shafts under variable sea state conditions.

Unmanned Aerial Vehicle (UAV) Engine Mounting

Stabilizes lightweight engine assemblies against asymmetric loading and resonance during high-G maneuvers or extended surveillance flight profiles.

High-Speed Rail Power Module Mounting

Supports vibration-isolated traction motor housings, reducing transmission of dynamic forces into cabin and undercarriage frame during high-speed operation.

Helicopter Turboshaft Engine Mounts

Manages axial and radial load transfer from turboshaft engines to airframe, compensating for rotor-induced vibration and pitch axis oscillations.

Controlled Deflection to Prevent Load Transfer to Adjacent Systems

Struts must not transfer unwanted forces or deflections to avionics mounts, airframe panels, or accessory systems during transient events like engine spool-up or emergency shut-down. Controlled deflection characteristics are engineered through precise bushing geometry, radial compliance tuning, and finite element simulation.

Engine mount interfaces frequently experience micro-motion under load, leading to fretting corrosion and crack initiation. Material systems and surface treatments are selected based on resistance to galvanic coupling and wear-induced oxidation. Interfaces are treated with high-performance dry film lubricants or plasma coatings tested to MIL-STD-810 environmental standards.

Having Doubts? Our FAQ

Check all our Frequently Asked Question

How does Frigate ensure consistent performance of engine mount struts under prolonged vibrational loads?

Frigate performs frequency response analysis (FRA) and resonance mapping for each strut design using actual engine excitation profiles. All components undergo dynamic fatigue testing up to 10 million cycles. This validates performance under real-world vibrational load patterns without degradation. Frigate’s materials are selected for stable damping coefficients across temperature and frequency ranges.

What kind of dimensional control does Frigate maintain to ensure precise engine-to-frame alignment?

Frigate uses CNC machining with ±0.01 mm tolerance control on critical interfaces. Each strut assembly is verified using coordinate measuring machines (CMM) for bore alignment, flatness, and angularity. Geometric Dimensioning & Tolerancing (GD&T) is applied to control stack-up across mounting points. This ensures consistent engine alignment without field rework.

How does Frigate mitigate failure from stress corrosion in hostile environments?

Frigate uses high-strength, corrosion-resistant alloys such as 17-4PH and coated 4130 steel. All contact interfaces are treated with anti-fretting coatings tested to ASTM B117 and MIL-STD-810 standards. Struts are sealed or isolated using bushings designed for galvanic compatibility with adjacent materials. Full material traceability and surface treatment data are included in documentation.

Can Frigate support engine mount strut customization for non-standard load profiles or hybrid configurations?

Yes, Frigate uses FEA-driven design iterations to optimize load paths for asymmetric or hybrid engine layouts. Custom damping behavior and compliance values are tuned using elastomer formulation or composite layering. Our team works with platform-specific load envelopes and transient conditions. Deliverables include load-deflection curves and vibration transmissibility data.

What testing does Frigate perform to validate engine mount struts for aerospace-grade performance?

Frigate conducts axial, torsional, and radial static load tests along with cyclic fatigue testing per RTCA DO-160 and MIL-STD-810 standards. Thermo-mechanical cycling simulates real operational stresses, including altitude temperature ranges and pressure variations. Vibration testing covers sinusoidal and random profiles in all three axes. Each batch is serialized and comes with full QA documentation and test reports.
