EN 4459:2005 - Aerospace series - Studs, in titanium alloy TI-P64001, with serrated locking ring in corrosion resisting steel - Design standard

Overview

SIST EN 4459:2006 is a European standard developed by CEN, specifying design guidelines for aerospace studs made from titanium alloy TI-P64001, equipped with serrated locking rings manufactured from corrosion-resistant steel. This standard focuses on the use and installation hole dimensions of these studs in aerospace applications. It also provides critical provisions to facilitate component salvage when necessary.

The standard caters to the high-performance requirements of aerospace engineering by ensuring reliable fixing components that meet stringent material and installation criteria. SIST EN 4459:2006 aligns with other aerospace standards, promoting consistent quality, compatibility, and safety in aircraft manufacturing and maintenance.

Key Topics

  • Material Specifications
    The studs are fabricated from titanium alloy TI-P64001, selected for its strength-to-weight ratio and corrosion resistance. The locking ring uses corrosion-resistant steel with serrated edges to secure the stud during operation.

  • Design and Installation
    The studs feature serrated locking rings that interlock with serrations in the installation hole to prevent rotation once installed. Installation requires precise hole dimensions and optionally, spotfacing on bearing faces for soft materials like aluminum alloys to avoid deformation.

  • Hole Dimensions and Serrations
    SIST EN 4459:2006 details exact hole diameters, pitch, depth, and serration profiles necessary for correct installation and firm fixing. Serrations are mandated in harder materials to ensure a secure locking ring fit.

  • Application Conditions and Limitations
    The standard confirms studs are suitable for use in light alloys, titanium, and nickel alloys and compatible with blind or through holes. The studs are not designed to carry shear loads or be used on rotating parts. Maximum operating temperature is specified as 350°C.

  • Component Salvage Considerations
    It outlines guidelines on how to account for component salvage in design, recognizing that repair considerations affect wall thickness and component weight, crucial in aerospace manufacturing economics.

  • Designation and Drawing Practices
    The standard prescribes a clear designation format for studs and corresponding holes, facilitating precise identification. It also describes how to present holes and assembly details in technical drawings.

Applications

SIST EN 4459:2006 is essential for aerospace manufacturers, engineers, and maintenance teams involved in:

  • Designing and producing aerospace components that require high-strength fasteners with corrosion resistance and reliable load-bearing capacity.
  • Installing titanium alloy studs with serrated locking rings into aircraft structural elements with optimized hole preparation to ensure secure assemblies.
  • Maintaining and repairing aerospace components by understanding installation methods, salvage provisions, and compatible materials.
  • Aerospace quality assurance processes, including testing of stud installation to confirm compliance with dimensional and functional requirements.
  • Designing aerospace joints where lightweight fasteners with specific mechanical properties are critical for safety and performance in demanding environments.
