Therefore, independently from the specific interest of ACIENG as end users members of the consortium, this task aims at determining the requirements of the system in order to respond to this multi-stage flexibility.
RTM Leading Edge Challenge
During the period 2016-2017, Aciturri Engineering has been leading the project “Development of leading edges in RTM”, which it is executing together with Aciturri Composites and the technology center CIDAUT, in an R&D program that forms part of the "COLLABORATION CHALLENGES" funding program. The challenge of the project is to be able to manufacture a new leading edge concept using the RTM technique and considering high production rates.
SLS Aero Project
The general goal of the project is to undertake the necessary research for the definitive and industrial application of additive manufacturing (AM) technology in the aeronautics industry, allowing the mass production of flight parts and tooling, which is to say, to increase the TRL of metallic additive manufacturing technology in the aeronautics market.
The following specific technical objectives have been proposed to achieve this:
- Determine the current capacity of AM technology using laser sintering to address the high-level requirements of the aeronautics industry.
- Increase knowledge of the influence of the principal variables of the laser sintering process on the final quality of parts (structural performance, metrology, etc.).
- Determine the possibility of maintaining the capacity for homogenization, repetition, and reuse of the material from AM technology, while still responding to the industry's requirements.
- Determine the current capacity of AM technology using post-processing to address the high-level requirements of the aeronautics industry.
- Increase knowledge of the influence of the principal variables of the post-processing processes on the final quality of parts.
- Validate findings by manufacturing tests of prototypes on a laboratory scale to demonstrate the capabilities and real needs of the complete technology (laser sintering + post-processing).
- Determine the most suitable process conditions that will make it possible to certify additive manufacturing processes for obtaining aeronautical components in the future.
Degree of homogeneity, repeatability and reuse of ALM technology materials applied to aeronautical sector requirements.
In order to study the repeatability of the process along with its quality, different experiments have been made that have allowed to analyze both mechanical properties and tolerance. Results indicate that the process is repeatable and that no significant differences are identified between the different working areas in the work platform of the SLS equipment.
Identification of the variables of operation of the laser sintering process more adequate to respond to the needs of the aeronautical sector.
We worked on the design, development and manufacture of test pieces, ad hoc parts and demonstrators. During the processes, we have evaluated the manufacturing strategies and machine parameters most appropriate to get the best results both from the dimensional and physical-mechanical point of view of each element. This experience has served to establish the most appropriate manufacturing methodologies to build right parts, guarantee repeatability of the process and its homogeneity.
Finishes and dimensional tolerance.
High requirements required in finishing and dimensional tolerance are characteristic of the manufacturing processes of the aeronautical sector. Inside this framework, analyzes, experiments and studies related to different technologies have been made, complementing the SLS, allowing to improve surface finish and achieve the required dimensional tolerance.
Identification of suitable materials for the aeronautical sector within the families of metal alloys previously identified as more appropriate.
Inside of aeronautics requirements, the metallic materials used are characterized by providing adequate mechanical properties with the smallest weight as possible. In this case, one of the materials most used is a titanium alloy (Ti6Al4V), which brings lightness at the same time as resistance. The studies made in the SLSAero project have focused on the analysis of this material and the results have been positive. Titanium alloys processed by SLS have high capacities for the aeronautical sector.
