The structures area of RO-RA includes the development, production and quality control of structural parts, machined metal assemblies and connectors, such as those used in the tail unit of an airplane or in the wings. The high degree of manufacturing competence of our team can meet the diverse needs of our customers with absolute reliability.

Structures manufacturing offers a comprehensive in-house production including the entire control of critical manufacturing processes and a highly efficient quality assurance. All stages of 3D modeling, 2D engineering, computation and load testing, a final compression and tensile stress analysis and a lot more are subject to the high quality requirements of our enterprise, industrial standards, customers’ requests and of course environmental standards.

CONTROL RODS: Structural Strut

RO-RA develops and manufactures all different kinds of structural rods including metallic rods, engine mounting rods, engine rod assemblies, steering rods, turnbuckles and rotary/swaged rods. The development comprises of the conceptual design, 3D modeling, 2D engineering, stress calculation and verification, ultimate compression & tension load analysis & testing, fatigue cycling, windmilling analysis & testing, weight evaluation as well as environmental testing according to industry standards or unique customer requirements.

Our structural struts are manufactured by using aluminum, titanium or stainless steel and are swaged in a cold forming process (rotary swaging without changes to the microstructure). Comprehensive testing is made to qualify structural struts including dye penetrate inspection, electromagnetic particle examination, grain size and grain flow inspection, radiography or radioscopy inspection, allowable defects testing (on threads, transverse section, longitudinal section) and paint thickness inspection. Special processes such as insert threading and thread forming are in place. The milling of rod ends is done in-house.


Our modern production provides a comprehensive in-house production with full control of the critical manufacturing processes, including:

Tube swaging
Tube swaging with swaged-in inserts
Rod end and fork end milling
Top of the edge qualified bearing swaging equipment
Surface treatment
Final assembly



Machined metal assemblies

The machining metal packages comprise of different aluminum, titanium, steel and plastics complex machined brackets which are fully assembled, tested and surface treated.

The assembly of the detail components include the injection grouting of the bearings, surface treatment, fasteners installation and sealant application. The milling metal parts comprise of different premium and high-tensile steels and adequate surface treatment. High-tensile steels are mainly used for structural assemblies (Aileron, Spoiler, Flap Track, Fairings, Stabilizers,..).

RO-RA mills and machines offer a wide range of raw materials, including:

All kinds of aluminum (AL2024, 2099, 6061, 7050, 7075)
Steel, stainless steel and hard steel with high chromium and nickel alloys
Titanium
Inconel


We provide benefits to the aviation industry with:

High flexibility in production
Competitive pricing
Wide range of material applications
Improved cycle times

Connectors

RO-RA develops and manufactures all different kinds of Connectors, Flanges, VI-Breaker and Air Ducts. The development comprises of the conceptual design, 3D modeling, 2D engineering, stress calculation and verification and weight evaluation.

Our connectors are manufactured by using aluminium or titanium and are typically machined out of block or bar material to ensure that highest part integrity is provided. RO-RA has developed special machining processes to reduce machining time and set-up costs.

The geometries of the connectors are all different and are fully customized for each customer. Comprehensive testing is made to qualify the Connectors including dye penetrate inspection, electromagnetic particle examination, grain size and grain flow inspection, radiography or radioscopy inspection, allowable defects testing (on threads, transverse section, longitudinal section) and paint thickness inspection.


Our modern production provides a comprehensive in-house production with full control of the critical manufacturing processes, including:

Pre-cutting of Material
Turning and Milling of Parts
Cleaning of Parts
NDT inspection
Surface treatment
Final assembly
