Introduction Fokker Aerostructures

We are market leading and technology leading in aerostructures, supporting our customers in making aircraft fly faster, further and greener. We provide empennages, wing structures, fuselages and components for major platforms ranging from helicopters to business jets and from advanced fighter aircraft to the most used single aisle aircraft and the largest passenger planes in the world. With lightweight composites, additive manufacturing and innovative high speed machining technologies we help to reduce emissions and weight on the aircraft and enhance passenger comfort.

Future WF (RiaM)

With the Rudder In A Month (RiaM) project we want to reduce lead time for the design process.

Using:
Standardized design process. Workflow with integrated design logic and MDO.
Design process innovation (including knowledge management and IT

infrastructure).

Re-use of knowledge. Formalizing tacit knowledge and best practices.
Real-time connection between knowledge and solution / geometry.
Automation of business process and tasks where possible and helpful.
In order to:
Accelerate the execution of tasks on the critical path.
Reduce non-recurring cost of the total program by more than 50%.
React quicker to customer requests and changes.
Improve and expand available knowledge by front loading process (e.g. sensitivity

analysis, design space exploration, driving design parameters) and virtual rapid prototyping, in order to aid the creative process.

Improve quality of the product and process by having a predictable design process,

performing more iterations and having automated requirements compliance checks.

RiaM is not limited to Rudders only.
Objectives achieved for thermoplastic movable

Using large files in file variables is not working well
Using plugins very user friendly
Linking input and outputs is very easy
QuickWrap very useful for programs which do not have a plugin
Centerlink components are very useful for web based access
