Within the scope of the Cleansky Programme, CIDAUT leads a research project aimed at the manufacturing of composite rotorcraft blades with very tight tolerances that will incorporate an Active Gurney Flap mechanism. Active Gurney Flap (AGF) systems enable the rotorcraft to safely operate with reduced tip speeds while preserving high performances with reduced fuel consumption and noise; something that constitutes one of the most challenging research areas led by the Green Rotorcraft Consortium in the Cleansky Programme: the development of Active Rotor Technologies.

In the ACCUBLADE project, CIDAUT researches on the development of a robust and very accurate molding process for the manufacturing of carbon fiber model blades that will be used for validation of the AGF systems through wind tunnel tests. Due to the small scale of the model blades, the dimensional requirements for the manufacturing are very tight, less than +/- 0,1mm on the aerodynamic profile. In order to fulfill the tight tolerances, not only the mold must be machined with high precision means, but also the cavity design must be defined with special consideration for minimizing any distortion during the process.

The analysis of potential process-induced distortions, such as warping or spring-in, has been carried out by means of process simulations based on accurate material parameters identified through laboratory material characterization tests. The influence of different material and processing parameters including the weave pattern, ply stacking, mold interaction, curing temperature and pressure has been experimentally characterized and correlated with the simulation models. These have been developed for the prediction of the distortions that would appear during the processing of the model blades. Using this methodology, the design of the cavity can be defined to fulfill the required tolerances.

During the close to follow validation stage, CIDAUT will take part in the processing of the model blades and the non-destructive and destructive inspection tests that will be carried out to demonstrate the functionality of the tools and to validate the design methodology.

In particular, the following outcomes from the ACCUBLADE project will stand out among the technological expected results:

  • An optimization methodology for tooling and molds design based on accurate distortion simulations accounting for different thermal coefficients of the composite materials.
  • A reduction in current development costs and lead-times for aeronautic composite parts, that usually need expensive and long lasting trial and error procedures to be carried out before a suitable mold cavity design is experimentally determined.

3. Development
3.1. Evaluation and selection of suppliers
The Foundation Purchasing Manager establishes the criteria based on which the evaluation and selection is carried out in order to guarantee that the selected supplier supplies the products and services in accordance with the necessary requirements. The selection criteria are a combination of the following depending on the type of product/service:

  • Ability to meet legal requirements and customer requirements
  • Adaptation to the specific need: For complex products/services, the proposal of the supplier that best meets the need
  • Technical Capacity: The supplier has the appropriate material and human resources
  • ENAC accreditations: The supplier is accredited by ENAC for the development of calibrations, tests, etc.
  • Certifications: The supplier has a current ISO 9001 certification and within its scope are the products and/or services that are the object of the need.
  • Provider recommended or established by the Client
  • Previous experience: Provider in other departments or projects
  • Market recognition
  • References from clients, competitors, etc.
  • Risk and guarantees: Level of risk assumed by the supplier and/or guarantees offered
  • Financial Capacity: For large purchases
  • Supply Capacity
  • Flexibility towards changes
  • Accessibility
  • Ability to meet deadlines
  • Price
  • Payment method
In addition to the established criteria, whenever possible, for purchases exceeding the amount of 3.000? The selection of the supplier will be carried out by requesting offers from at least 3 suppliers.

3.2. Monitoring performance and reevaluation of suppliers.
To ensure that controlled external suppliers continue to supply in accordance with established requirements, suppliers are subject to periodic monitoring and control. Depending on the type of provider, it is established:

Supplier type Tracking Re-evaluation
Regular: regular suppliers X X
About project: specific suppliers for a given project X Does not apply
Occasional: single purchase suppliers Does not apply Does not apply

Tracking
Monitoring of external suppliers is carried out continuously:

  • Checking the maintenance of the ISO 9001 certification or ENAC accreditation that served as the basis for the approval. In case of loss, approval could be withdrawn.
  • Checking compliance with commercial agreements
  • Review of the quality of purchases made.
    • Anomalies attributable to the supplier are tracked. When an incident gives rise to a customer claim or significantly affects the outputs or results of the project, technological service or test, a Non-conformity is opened. When the supplier's response is not adequate or when the severity of the anomaly causes the CIDAUT Foundation to lose confidence in the supplier, the approval is withdrawn.
Continuous monitoring also takes into account response times and price developments. When necessary, the Purchasing Manager may define other monitoring activities. Some possible follow-ups are:
  • Audits
  • Service quality reviews
  • Visits to the supplier
  • Product inspections
  • Monitoring of indicators
  • Meetings with service users

Re-evaluation
Regular suppliers are periodically re-evaluated. For this, it is reviewed:
