Objectives: 

AMATHO (A.dditive MA.nufacturing T.iltrotor HO.using) is aimed to design, assess and manufacture a novel tiltrotor drive system housing exploiting the features of additive manufacturing techniques. Preliminarily, functional, structural and technological peculiarities of rotorcraft main gearbox housings are analysed and relevant requirements are issued.

 

Methodology: 

Viable AM processes will be reviewed, on the basis of specific suitability, technological potential and degree of maturity. In particular, powder feed direct energy deposition techniques (Direct Laser Deposition - DLD) and powder bed fusion techniques (Selective Laser Melting - SLM and Electron Beam Meelting - EBM) will be considered.

The powder precursors will be investigated as well, in terms of chemical nature (magnesium, aluminium, titanium alloy, stainless steel), particles granulometry and morphology. Static, fatigue, fracture mechanics, damage tolerance, corrosion endurance, chemical compatibility, machinability, weldability and heat-treatability testing will be worked out and final trade-off process accomplished for choosing optimal materials and processes.

Characterisation methodologies and NDI techniques will be assessed as well. In addition to test activity on dedicated specimens, smaller, but fully representative, full-scale gearbox housing components (to be considered as proof of concept) will be manufactured through the traded-off technologies and tested to check the compliance with general functional aspects of r/c drive system housing.

In parallel, design rules and methodologies for detail design, optimisation and structural substantiation of AM components will be defined and supporting numerical tools are set-up. Full-scale housing will be manufactured and structural and functional tests will be performed to support flight clearance on the NextGenCTR Demonstrator and procedures (engineering cost and industrial capability assessment) for the start-up of high-volume production will be defined.
