Recycling metallic materials from rotor aircraft transmissions

Efficient recycling is always a good objective, particularly when the materials are expensive. For aircraft, a major source of efficiency can be detailed processing protocols for each component.
Recycling metallic materials from rotor aircraft transmissions
The components of a transmission system have a finite life, and they have to be recycled. Some methods are less harmful to the environment and workers than others.

With EU funding, the project REMART (Recycling of metallic materials from rotorcraft transmissions) analysed the main recovery processes (dismantling, stripping, remelting etc.) and the design of recycling protocols to return the components to use. The approach targeted efficiency, profitability and environmental sustainability.

The main objectives were to optimise the use of existing technologies and to assign an efficient and environmentally sound recycling protocol to each piece of recovered material.

The first step in this work was the development of a comprehensive market survey. In parallel, a study and analysis of all materials and coatings used in the manufacturing of helicopter transmission systems was completed. Once all materials were identified, including main coatings and surface treatments, each piece could be assigned its most suitable recycling process sequence.

Two different demonstrator components were used in the project (tail gearbox and intermediate gearbox) to validate the developed recycling protocols. The last stage of the project involved a cost-effectiveness analysis of the two recycling cycles.

Recycling of metallic materials from rotorcraft transmissions results in a reduction of aerospace structure and systems environmental impact, a minimisation of the generation of waste associated with the aerospace industry, a reduction in emissions and a corresponding growth in European industry competitiveness.

Another aspect of the project is that the parameters analysed and the spreadsheet obtained may be used in conjunction with other engineering environmental tools such as life-cycle assessment, carbon footprint, life-cycle engineering and design for environment.

Project results and outcomes will boost aluminium recycling all over Europe. The main advantages and impact of the recycling of metallic materials from rotorcraft transmissions include energy savings, reduced emissions and reduced capital costs.
