Aileron Control Rod Fittings

Name: Aileron Control Link Fittings & Wing Rod Assemblies for Flight Systems – Frigate
Price: 249.00 USD
Availability: InStock

Aileron Control Rod Fittings endure complex multi-axis vibrations along the wing span, especially in transonic flight where aeroelastic flutter can trigger secondary structural modes. To ensure stability, these fittings are engineered with anti-rotation spline geometries and concentric spherical bearing mounts that maintain precise alignment under high-frequency excitation.

Material Specification

Titanium 6Al-4V (AMS 4928), Steel 4340 (AMS 6414), or Aluminum 7075-T73 (AMS 4050)

Control Rod Attachment Method

Threaded Fork End (UNJF-3B), Spherical Bearing (NAS 1431), or Rod End (AN/MS)

Aileron/Bellcrank Attachment

Clevis (SAE AS2301), Taper Pin (NAS 561), or Flanged Bolt (NAS 1441)

Pin Hole Diameter & Spacing

Ø6–25mm (H7 Tolerance), Spacing: 30–100mm (±0.1mm)

Load Capacity

Tensile – 15–50kN, Compressive – 10–40kN, Shear – 12–35kN

Product Description

Sub-micron machining tolerances—less than 2 µm on bearing bores—paired with line-to-line bearing fits effectively prevent oscillatory fretting. This design approach preserves control surface stiffness and eliminates progressive freeplay typically seen in older linkage assemblies, ensuring long-term responsiveness and reliability.

Fatigue Life

10⁷ Cycles @ 30% UTS (HCF), 10⁴ Cycles @ 70% UTS (LCF)

Stiffness/Deflection

≤0.2mm @ Design Limit Load, Natural Frequency >150Hz

Corrosion Resistance

Passivation (Ti), Cadmium Plate (Steel), Alodine (Al)

Dimensional Tolerances

Hole Position – ±0.05mm, Parallelism – ≤0.02mm, Surface Finish – Ra 0.8µm

Certification Standards

FAR 25.671, AS9100, NASM 1312, MIL-STD-1568

Technical Advantages

Fatigue-induced failure at thread roots is a known failure mode in control linkage assemblies subjected to cyclic tensile loading. Aileron Control Rod Fittings mitigate this through precision-rolled UNJ3A threads with optimized fillet radii to reduce stress concentration factors. Each fitting is treated with rotary shot peening, introducing compressive residual stresses to delay crack nucleation. Fatigue life is validated under variable amplitude spectrum loading per MIL-STD-1530, with observed growth rates remaining below 10⁻¹¹ m/cycle.

In swept-wing configurations, aileron actuation paths often encounter slight angular offsets due to structural flex and manufacturing variances. Aileron Control Rod Fittings are machined with bore centerline alignment maintained through dual-axis referencing during final inspection. Angular misalignment is constrained to less than 0.03°, preserving actuator linearity and avoiding asymmetric bearing loading. Coupled with matched clevis interface geometry, these fittings enable consistent aileron response under both static and dynamic wing loading.

Industry Applications

Fixed-Wing Aircraft Primary Flight Control Systems

Transfers lateral command input to aileron surfaces with minimal backlash under dynamic aerodynamic and inertial loading conditions.

Unmanned Aerial Vehicle (UAV) Wing Actuation Assemblies

Enables precise roll control in UAVs by maintaining alignment under variable payload-induced wing bending and torsional deformation.

Military Fighter Aircraft Roll Control Linkages

Withstands high-g maneuver loads and transonic flutter environments while maintaining torque path integrity and bearing concentricity.

Regional Jet Aileron Drive Mechanisms

Ensures consistent control response by compensating for thermal-induced linkage expansion during rapid altitude or environmental transitions.

Supersonic Flight Test Platforms

Functions in high-temperature, high-vibration envelopes while preserving joint preload and preventing thread-based fatigue failures.

Tiltrotor Aircraft Control Conversion Linkages

Supports transition between vertical and forward flight modes by handling changing control vector angles and loading axes.

Retaining Dimensional Stability Through Thermal and Flutter Loading

Thermal expansion mismatches and transient flutter loading induce dimensional shifts and vibratory strain on control hardware. Aileron Control Rod Fittings are built with dual-material architectures, combining low coefficient-of-expansion shaft segments with hardened raceways for bearing seats.

Procurement of structural hardware demands full material traceability and dimensional repeatability across all production lots. Aileron Control Rod Fittings are serialized and delivered with AS9102-compliant First Article Inspection Reports, full material test reports (per AMS/ASTM specifications), and coordinate metrology records. Heat treatment, anodizing, and nondestructive testing are conducted at NADCAP-accredited facilities, with all process steps documented per AS9100D flowdown.

Having Doubts? Our FAQ

Check all our Frequently Asked Question

How does Frigate ensure zero backlash in Aileron Control Rod Fittings during high-frequency control inputs?

Frigate machines all bearing seats with sub-2 µm runout and maintains tight line-to-line fits with spherical bearings. This prevents micro-slippage under high-frequency excitation from flutter or gust loads. Each assembly is dynamically tested under simulated control input frequencies to verify stiffness response. The result is near-zero backlash even in rapid actuation environments.

What fatigue life validation methods does Frigate use for Aileron Control Rod Fittings under spectrum loading?

Frigate performs fatigue life validation using variable amplitude loading based on representative fighter aircraft mission spectra. Crack initiation and growth are monitored under ASTM E647 compliance with R-ratio and frequency matched to actual flight profiles. Rotary shot peening is applied pre-assembly to introduce compressive stress zones. Final validation includes high-cycle durability tests exceeding 100,000 simulated flight cycles.

How are Frigate’s Aileron Control Rod Fittings protected from galvanic corrosion in mixed-metal assemblies?

Frigate selects alloy combinations with minimal galvanic potential difference based on electrochemical compatibility charts. Interface surfaces are coated using ion-assisted deposition to form a dielectric barrier below 10 µm thickness. Coating systems meet MIL-DTL-5541 and MIL-A-8625 where applicable. Every batch is tested in salt fog chambers for over 1000 hours per ASTM B117.

How does Frigate control angular alignment during final inspection of Aileron Control Rod Fittings?

Frigate uses dual-axis coordinate measuring machines (CMM) to verify bore alignment and shaft straightness within 0.03° angular deviation. Fixtures replicate actual clevis geometry to check true in-situ alignment. Assembly stack-up tolerances are reviewed using digital metrology software. This ensures consistent fit without inducing torsional strain in control linkages.

What quality documentation is delivered with Frigate’s Aileron Control Rod Fittings for aerospace compliance?

Each fitting from Frigate comes with full traceability including mill certs, mechanical property validation, and AS9102-compliant First Article Inspection Reports. NADCAP-accredited special process records for anodizing, NDT, and heat treatment are included. Dimensional inspection reports are provided using tactile and optical CMM outputs. All documentation complies with AS9100D flowdown and OEM configuration control standards.
