Project description
Femtosecond laser creates tiny holes on wing structures and enhances aircraft performance
Recent advances in femtosecond lasers have rendered them a valuable tool for micromachining and microdrilling applications. The EU-funded MULTIPOINT project plans to develop a femtosecond laser that can be used to drill tiny holes on large titanium plates that help stabilise air flow and minimise drag in aircraft. Unlike other laser technologies employed for perforating titanium surfaces, MULTIPOINT’s femtosecond laser will eliminate the need for surface post-processing. The technology does not create burrs or undesirable titanium microstructural phases in the heat-affected area surrounding the micro-holes. The ultimate aim is to develop a femtosecond laser source that delivers 1.2 kW power and new beam delivery technologies that optimise process parameters and maximise production.
Objective
MULTIPOINT's main objective is to develop a high power femtosecond laser system with a multibeam generation unit and custom beam delivery scanning and processing on the fly heads for high throughput micro-drilling of large Ti panels used in the fabrication HLFC structures in the aerospace industry. Three will be the key challenges to be adressed:
• A 1.2 kW femtosecond laser source working at high pulse energy will be developed. This laser has enough power to drive several synchronized processes of percussion drilling at the same time (parallel processing) and hence, maximize the production just taking into account aspects related to the increase of the energy provided to the sample.
• Secondly, a multibeam generation unit will be developed for splitting the main beam supplied by the laser source. This unit will be optimized not only optically but will take into account process optimization and application requirements. It will be designed to optimize the energy balance per beam in a pattern determined by the particular requirements of the micro-drilling of Ti panels for the development of HLFC structures.
• Finally, two strategies for delivering the multibeam pattern to the Ti panel based on the percussion drilling technique will be developed and tested. The first strategy involves the development of a multibeam scanner based on galvanometric mirrors. Its custom design will include a sufficient optical aperture to take a number of parallel beams to the sample, within a working field determined by a focussing f-theta lens, in a controlled environment by means of an inert Ar atmosphere chamber for process protection. The second head will be a multibeam on-the-fly processing head with pulse trains in a multibeam pattern and Ar jet nozzle. These two strategies will also allow us to study the best processing approach through the development of new beam delivery technologies to optimize the process parameters and maximize production.
