RepAIR

Future RepAir and Maintenance für Aerospace industry

Funding: Europäische Kommission, 7. Forschungsrahmenprogramm

Duration: 06/2013 - 05/2016

At the C.I.K. the following doctoral thesis resulted from this project: „Entwicklung einer Entscheidungsunterstützung für den Einsatz Additiver Fertigung in der zeitkritischen Ersatzteilversorgung“ by Gereon Deppe, 25.10.2018.

Description

The goal of this research project with twelve partners from all over Europe and from the USA is the onsite maintenance and repair of aircraft by integrated direct digital manufacturing of spare parts. Additive Manufacturing is ought to make the maintenance, repair and overhaul of aircrafts more efficient and effective. Therefore it is necessary to reduce the aircraft's downtime; this has to be achieved not only for the regular maintenance but also for urgent repairs. The challenge is to design cost efficient and lightweight parts but additionally ensure a high robustness and reliability of the parts. Additive Manufacturing offers a high potential for these requirements. The overall aim of the project is to shift the 'make-or-buy' decision to 'make' with respect of an on-site production. Spare parts should be manufactured completely or damaged parts should be repaired.

The chair C.I.K. of Universitaet Paderborn focuses in RepAIR on the requirements engineering as well as it focuses on the cost analysis to increase the cost efficiency. The requirements analysis and the accompanying requirements management provides as a basis for the development of the RepAIR IT Management Platform which is going to enable an optimized production and information flow for maintenance, repair and overhaul service providers. A basic aspect of the platform is the decision support tool that is mainly based on the cost calculation. This tool will be developed with respect to the product life cycle and the supply chain. It supports the decision between 'make' and 'buy' including further influence factors like ecological aspects. The C.I.K. has the responsibility to scientifically answer the basic questions and to demonstrate the additional benefit of the RepAIR solutions in contrast to the technology's state of the art. The investigation is based on workshops and interviews as well as the collaboration of the other project partners and work packages and especially on the intensive exchange with the end users within the project.

Objectives

  • Reduce the repair and maintenance costs of complex spare parts by 30% with simultaneously reduction of the turnover time with the help of innovative technologies
  • Increase the automation level for spare parts production processes through an integrated production and supply chain
  • Reduce scrap and toxic chemicals in the repair process and part weight by the use of a new production technology
  • Increase the technology readiness level (TRL) of innovative repair processes for aeronautics focusing on the AM technology
  • Develop processes to decrease certification effort for additive manufactured aerospace spare parts in terms
    of cost and time based on an integrated quality control and process data monitoring
  • Reduction of inspection time by integrating continuous health management and usage based prognostics
  • Prediction of costs and future possibilities of AM technologies for MRO in 2020

Research at C.I.K.

In RepAIR, the C.I.K. department of the University of Paderborn focused on the determination of requirements to achieve the objectives as well as cost analysis to increase cost efficiency. The determination of the requirements and the accompanying management served as a basis for the development of the RepAIR IT Management Platform, which should enable an optimized production and information flow in maintenance, repair and overhaul companies. An essential component of this platform is the decision support tool, which has the cost calculation as a basis. This tool has been developed on the basis of the supply chain and the product life cycle and supports the decision between 'make' and 'buy', taking into account other influencing factors such as ecological factors. The C.I.K. took on the task of providing scientific answers to fundamental questions and demonstrating the added value of RepAIR solutions compared to the current state of the art and science. The investigation was based on workshops and interviews as well as the cooperation with the other project partners and work packages, but especially on the intensive exchange with the end users in the project.

 

This project has received funding from the European Union Seventh Framework Programme (FP7/2007-2013) under grant agreement n°605779.
