PRODUCT DETAILS INTERIORS
Setting new standards: RO-RA is clearly the leader when it comes to Aerostruts
Interior products connect the fuselage with the interior of the cabin.
+43 7662 57888
Our interior products connect the fuselage with individual cabin elements. This means overhead compartments as well as galley kitchens, stowage boxes or the wet cells. We ensure that the aircraft even after high stress - such as when landing - remains stable and does not fall apart.
The development of our high-quality components is based on 3D modeling and 2D engineering. We focus on the individual customer needs in compliance with the strict standards and testing requirements of the industrial standards of the aviation industry such as compression and tensile stress analysis, free rotation analysis, cyclic fatigue tests, environmental tests, etc.
RO-RA develops and manufactures all different kinds of tie rods including drag links, rotary rods and connecting elements in conjunction with integrated shock mounts and attachment brackets.
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.
The AEROSTRUT® system includes an integrated/inner distortion lock mechanism with independent anti-twist devices. The system allows significant improvements during the installation process at the assembly lines of our customers.
The adjustability range for the ends is up to +/- 75mm or +/- 3 inches in overall. The AEROSTRUT® System is supplemented with fork end locking clips which are clipped on the threaded sleeve by one hand, a loose prevention feature for the interface pins and a maximum turn-out device.
The AEROSTRUT® system provides major benefits to the aviation industry by:
Significantly reducing cycle times at installation
Plug & play solutions
Reduced testing for design adaptations
No tooling for adjustments and adjustability requirements
No wire lock
No counter nuts
High adjustability with a range of +/- 50mm or 2 inches
High resistance against environmental conditions
Optional loose prevention
Pivot Point Kinematics
The core competences of RO-RA are the development, product definition, qualification & testing as well as the production of pivot point kinematics which comprise of the pivot mechanism, damper unit, lift assist and damper bin brackets.
The development comprises of the conceptual design, 3D modeling, 2D engineering, stress calculation and verification, acoustics and vibration computation, 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.
The pivot point kinematics was developed to support narrowbody and widebody interior configurations and provides a modularity concept.
The benefits of our lift assisted kinematic system are:
Simple and quick installation and removal of the stowage bin units by using an integrated clip system
Light weight solution by utilizing thermoplastic materials for the pivot point elements considering high stiffness, loading and cycling requirements.
Very low lift assist requirements for the closing of the stowage bins and significant support of the damper system during the opening process
AEROSHOCK® and lower attachment fittings
RO-RA develops and manufactures all different kinds of shock mounts with axial and radial applications (also combined), different stiffness, damping behaviors and amplitudes as well as integrated devices in metal brackets, injection moulded & glass fiber reinforced brackets or other substructures.
The AEROSHOCK® system comprises of the machining and milling of metal parts and applications with the design & manufacturing of elastomeric shock absorbing, noise, temperature and vibration dampening devices. The standard features include axial & radial applications with a stiffness range of around 25N/mm to 4500N/mm. The standard features include axial applications with different stiffness ranges and hardness behaviors according to the customer's requirements (from stiffness range of 25 N/mm to 4500 N/mm) with respect to different amplitudes and end stops.
RO-RA develops customized and integrated AEROSHOCK® solutions for our customers, including:
Elastomeric rod ends
Seat rail attachment shock mounts and absorbers
Fixed pin lower attachment shock mounts and absorbers on hard-points to AC structures
Axial & radial shock mounts for monuments & overhead stowage bins with adjustable brackets
Axial & radial shock mounts for sidewalls with adjustable brackets
Lining panels axial shock mounts with quick release fitting systems
Shock mounts with spherical bearings
AEROLIFT® - Dampers
RO-RA develops and manufactures all different kinds of linear and rotary dampers, actuators, gas springs, hydraulic dampers, vibration dampers, lifting columns, piston rods or seat reclines in conjunction with integrated quick release ball cup features.
The development comprises of the conceptual design, 3D modeling, 2D engineering, stress calculation and verification, ultimate compression & tension load analysis & testing, life cycle testing, windmilling analysis & testing, weight evaluation as well as environmental testing accordning to industry standards.
Our AEROLIFT® system provides improved homogeneity of damper motion and a massive reduction of the “air jump” effect due to a new, innovative valve system. The system includes a safety relief valve for overload protection in case of misuse.
The AEROLIFT ® system provides major benefits to the aviation industry with:
Damper systems especially developed for the aircraft industry
High performance lifetime
No air jump during operation
No pressure loss during opening/closing process
Load-dependent damping action
High corrosion resistance
Multiple end fitting designs available based on customer requirements
Injection Moulded Parts
All common plastics and special technical plastics (e.g. glass fibre filled) are used for the development and production of aviation products. Thermoplastic-elastomers (TPE) are applied in areas where product requirements and temperature are sensitive.
Other thermoplastics are utilized including PPS, PEI, PC, PA, POM and ABS. The application of PEEK will be introduced.
Following processes are in use at RO-RA:
Glass fiber filled or carbon fiber filled
Two-component injection moulding
Internal gas pressure moulding
We provide benefits to the aviation industry by:
Flexible manufacturing system
Wide range of material applications
Improved cycle times
