4-8 Holes (NAS/MS Bolts), PCD 120-250mm, Flush/Rail Mount Options

Retention Method

Shear-Bolt Clamp (M8-M12), V-Block with 200-500N Clamping Force, Quick-Release Lever (MIL-C-5040)

Crash Load Capacity

3,400g (TSO-C124), 20kN Static Load, Fireproof to 1100°C (60min)

Product Description

This design effectively attenuates high-frequency microvibrations, preventing false triggers in accelerometers and maintaining accurate timestamp synchronization in high-speed data logging systems, even under demanding operational environments.

Vibration Control

Isolation Pads (30-70 Shore A), Natural Frequency >500Hz, DO-160 Cat S

Temperature Range

-65°F to +160°F (Standard), -100°F to +400°F (Engine Bay)

Dimensional Tolerances

Clamp Alignment – ±0.2mm, Flatness – 0.1mm/m, Hole Position – ±0.05mm

Certification Standards

TSO-C124/ED-112A, FAR 25.1457, EU 996/2010, AS9100

Technical Advantages

Recorder displacement due to structural flex or thermal strain alters reference geometry and impacts data accuracy. The clamp architecture is modeled using finite element analysis to ensure minimal deflection under torsional and axial loads. Materials with matched coefficients of thermal expansion are selected to prevent clamp stress on the recorder housing during extended high-altitude or supersonic operations where temperature gradients exceed 200°C.

Sensor offset errors arise when data recorder mounting clamps introduce tilt or drift under mechanical load. High-precision alignment features such as dowel pin bores, anti-rotation shoulders, and multi-axis nesting surfaces are integrated to maintain recorder orientation within ±0.02° over the entire load cycle. This is essential for inertial navigation systems or mission recorders requiring consistent reference frames relative to the vehicle body axis.

Industry Applications

Flight Test Instrumentation Systems

Supports secure mounting of flight data recorders during dynamic loading, preserving alignment under high-G, vibration, and thermal cycling conditions.

Black Box Integration in Commercial Aircraft

Ensures rigid, vibration-isolated attachment of FDR units, maintaining recording fidelity during turbulence, engine resonance, and emergency maneuvers.

Defense Avionics Data Acquisition Modules

Provides mechanically stable interface for mission recorders inside rotorcraft or UAVs operating under rapid attitude changes and environmental extremes.

Missile Telemetry Recorder Mounting

Secures high-speed data logging units within constrained fuselage space, tolerating extreme accelerations and transient shock during launch events.

Satellite Subsystem Recorder Fixtures

Maintains fixed positioning of space-grade recorders relative to inertial frames, ensuring uninterrupted data collection during orbital maneuvers and deployment.

Helicopter Crash Recorder Assemblies

Supports structural survivability of crash-survivable memory units, preserving alignment through high-frequency rotor vibrations and impact shock scenarios.

Minimizes Electrical Interference from Structural Coupling

Recorder ground loops and induced noise from conductive airframes can interfere with high-frequency signal paths. Electrical decoupling is achieved using dielectric spacer materials combined with optional grounding continuity paths verified through low-resistance bonding.

Dynamic environments such as carrier takeoffs, missile launches, or hard landings produce impulse loads that exceed 20G. The clamp structure is validated through static and modal testing to withstand such conditions without yielding or allowing recorder displacement. Fastener preload recommendations and thread locking features are provided to maintain mechanical integrity under shock and vibration spectra defined in RTCA DO-160G.

Having Doubts? Our FAQ

Check all our Frequently Asked Question

How does Frigate ensure precision alignment in its data recorder mounting clamps for directional sensors?

Frigate machines all alignment surfaces using CNC equipment with ±0.01 mm tolerance control. Locating pins and anti-rotation features are integrated to prevent angular drift. This ensures recorder orientation stays constant during flight or dynamic test conditions. The data recorder mounting clamps are validated for stability across mechanical and thermal cycles.

What materials does Frigate use to avoid thermal mismatch between the clamp and aircraft structure?

Frigate selects alloys like 7075-T6 aluminum and Ti-6Al-4V titanium for matched thermal expansion with recorder housings. These materials reduce internal stress during temperature changes at altitude. Structural integrity and mounting force remain consistent across extreme operating ranges. This avoids recorder deformation or signal path distortion.

How does Frigate validate clamp performance under real-world vibration profiles?

Each data recorder mounting clamps design undergoes modal and harmonic response analysis during development. Physical prototypes are tested using sine and random vibration profiles per DO-160G. Fastener loosening, displacement, and resonance behavior are recorded. Frigate also evaluates fatigue life to ensure long-term durability.

Can Frigate's clamps be used in missile or high-acceleration applications?

Yes, Frigate designs clamps to withstand accelerations over 20G using load-path optimized geometries and aerospace-grade materials. Shock absorption layers can be included where necessary. Finite element models simulate dynamic impulse events for critical applications. Structural margins are maintained above 1.5x the design load.

What options does Frigate offer for EMI shielding in recorder mounting?

Frigate provides data recorder mounting clamps with optional integrated grounding paths, conductive gaskets, or non-conductive isolation layers. These options reduce EMI transfer from the airframe to sensitive electronics. Electrical continuity or isolation is verified during final inspection. All EMI configurations meet requirements for MIL-STD-461 environments.
