Actuator Interface Design

Spherical Bearing Socket (NAS1431), Flanged (NAS/AN Bolt Pattern), or Spline Interface (SAE J498)

Load Capacity

Static – 25-100kN, Dynamic – 16g Crash Load (FAR 25.561), Shear – 15-60kN

Stiffness/Deflection

≤0.15mm @ Limit Load, Natural Frequency >100Hz

Fatigue Life

10⁶ Cycles @ 30% UTS (LCF), 10⁷ Cycles @ 20% UTS (HCF)

Product Description

Frigate ensures sub-20-micron positional accuracy in these brackets through advanced five-axis CNC machining and rigorous multi-step inspection protocols. This precision prevents misalignment-related issues and supports long-term actuator and airframe reliability.

Aircraft Mounting Points

4-8 Bolt Holes (NAS/AN/MS), PCD 50-150mm, Threaded Inserts (Keensert/Helicoil)

NDT Requirements

Fluorescent Penetrant (FPI), Ultrasonic (UT), X-ray (Welds)

Corrosion Resistance

Anodizing (Al), Passivation (Ti), Cadmium Plate (Steel per AMS 2416)

Dimensional Tolerances

Hole Position – ±0.05mm, Bore Diameter – ±0.01mm, Flatness – ≤0.1mm/m

Certification Standards

FAR 25.571, AS9100, AMS 2750 (Heat Treat), BMS 7-260

Technical Advantages

Flap actuator brackets operate in high-cycle fatigue zones and are exposed to complex loading scenarios involving shear, bending, and torsion due to wing flexure and actuator motion. Improper material selection or poor geometry transitions can result in fatigue crack initiation at mounting lugs or weld interfaces. Frigate applies high-fidelity FEA simulations across full actuation load cycles, incorporating wing deflection inputs and actuator stroke profiles. Resulting designs feature stress-relieved transition radii and load path continuity without abrupt geometry changes, which ensures long-term durability and resistance to high-cycle fatigue propagation.

Localized deformation in brackets during actuation, especially under asymmetrical flap loading or crosswind conditions, can cause persistent actuator misalignment or coupling backlash. Standard aluminum alloys often lack the required modulus-to-weight ratio needed for such conditions. Brackets are fabricated using aerospace-grade alloys such as 7050-T7451 or Ti-6Al-4V, selected for their superior fatigue strength, stiffness, and corrosion resistance. Material batches are subjected to ultrasonic inspection and grain flow validation, and mechanical properties are verified post heat treatment to confirm compliance with MIL-HDBK-5 or MMPDS structural criteria.

Industry Applications

Commercial Aircraft Wing Flap Systems

Used to support and align actuators controlling high-lift devices on large airliners during takeoff, landing, and approach phases.

Military Fighter Aircraft Trailing-Edge Flaps

Integrated into high-load flap systems to manage rapid actuator deployment under variable aerodynamic pressure and extreme maneuvering conditions.

Regional Jet Actuation Assemblies

Facilitates compact actuator mounting in confined wing structures where weight constraints and precision stroke control are critical.

Unmanned Aerial Vehicle (UAV) Flight Control Surfaces

Supports miniaturized actuator systems used for precise flap deployment in autonomous aerial platforms requiring high reliability and low mass.

Business Jet Variable Camber Systems

Enables precision load transfer in high-performance wing sections with variable geometry flaps designed for efficiency at multiple cruise conditions.

Transport Aircraft Cargo Door Flap Systems

Provides actuator support for deployable aerodynamic surfaces near cargo doors that assist in low-speed handling during heavy load operations.

Configuration Traceability and Quality Compliance Across Programs

Aerospace and defense programs require traceable hardware with deterministic process controls and validated repeatability across multiple production lots. Missing documentation or variable geometry between brackets from different batches compromises airworthiness and complicates rigging operations. Each bracket is delivered with full material traceability (including mill certs and batch IDs), dimensional inspection reports, and heat treatment logs.

Brackets must interface accurately with various actuator models—whether electromechanical, hydraulic, or hybrid—without inducing constraint mismatches or excessive actuator side loads. Improper actuator-bracket coupling geometries can cause internal bearing misalignment and reduced stroke fidelity.

Having Doubts? Our FAQ

Check all our Frequently Asked Question

How does Frigate ensure consistent bracket geometry across multi-lot aerospace production runs?

Frigate uses CNC machines with in-process probing and closed-loop feedback to maintain geometry within ±0.01 mm tolerance across all units. Each lot is verified through statistical process control (SPC) and CMM-based dimensional reports. Tool wear compensation is managed digitally, ensuring zero drift in critical features. This guarantees geometric consistency for multi-aircraft integration without requiring field adjustments.

What design methods does Frigate apply to avoid fatigue cracks in actuator mounting zones?

Frigate performs high-cycle fatigue analysis using FEA on all critical stress zones, especially around actuator lugs and bolt interfaces. Brackets are designed with optimized transition radii and fillet blends to prevent stress concentration. Post-machining shot peening is applied to improve surface compressive stress. These design controls significantly delay crack initiation in service.

How does Frigate address thermal distortion during bracket heat treatment?

Brackets are heat-treated using calibrated profiles that account for alloy-specific thermal expansion behavior. Fixturing is used to constrain key geometry during quenching or aging to reduce warping. Final machining occurs post-treatment to restore dimensional integrity. This method ensures that mounting surfaces remain within flatness and parallelism limits.

What documentation does Frigate provide to support aerospace compliance audits?

Frigate delivers full AS9102 First Article Inspection Reports (FAIR), NADCAP process certs, and mill certifications with every shipment. All machining and finishing operations are traceable by part serial and batch number. 3D CAD validation files and CMM inspection datasets are also available. This enables seamless integration into OEM supplier audit systems.

How does Frigate prevent actuator misalignment caused by bracket-hole positional error?

Hole positions on Frigate’s brackets are controlled using multi-axis machining and post-process reaming for exact concentricity. Datum-based inspection ensures all bores are aligned to mounting planes with minimal angular deviation. This prevents angular load transfer into the actuator shaft. Proper alignment ensures correct actuator stroke and avoids feedback errors in the flap control system.
