Overview

EN 2587:1990 is a European standard published by CEN that specifies the dimensional and load requirements for aerospace series adjustable rod ends featuring a double fork and threaded shank. These rod ends are critical components used primarily in flight control rods and various aerospace structural applications. The standard ensures that these components meet stringent quality, safety, and performance criteria required in the aerospace industry.

Rod ends covered by EN 2587:1990 consist of a rod end body with a threaded shank, a double fork designed to interface precisely with mating parts, and specific grooves to assist with location identification and optional locking. The cadmium plating applied to these rod ends restricts their operational temperature to a maximum of 235°C, ensuring durability and corrosion resistance under aerospace operating conditions.

Key Topics

• Adjustable Rod Ends: Detailed specifications for adjustable rod ends featuring a double fork design and threaded shank for precise mechanical linkage.
• Dimensional Specifications: Exact measurements and tolerances to ensure interchangeability and compatibility with aerospace flight control systems.
• Load Capacities: Defined mechanical load limits that the rod ends can safely withstand during operation.
• Groove Features:
  • Circumferential Groove: Used for location identification.
  • Longitudinal Groove: Optional feature for locking purposes to prevent loosening under vibration.
• Material and Coatings: Use of cadmium plating to provide corrosion resistance with a thermal application limit of 235°C.
• Safety and Reliability: Standards aimed at ensuring the structural integrity of rod ends used in aerospace components subjected to dynamic loads.

Applications

EN 2587:1990 compliant rod ends are essential components in aerospace engineering, where precise control and reliable mechanical linkages are paramount. Typical applications include:

• Flight Control Systems: Connecting control rods and actuators to enable precise movement of control surfaces such as ailerons, rudders, and elevators.
• Aerospace Structural Assemblies: Serving as adjustable joints in structural rods for load distribution and adjustment in aircraft fuselage and wing assemblies.
• Maintenance and Repairs: Standardized rod ends simplify component replacement and maintenance in aerospace vehicles by providing consistent dimensions and load ratings.

These rod ends are optimized for aerospace use where operating conditions involve cyclical loads, high safety margins, and controlled environmental exposure.
