Research groups of LNCA present research lines to ITA's Special Programme in New Concepts in Aeronautics and Intelligent Structures (PE-AERO)
Projects recently approved by FINEP INOVA AERODEFESA - a partnership with
Higher aspect-ratio wings and the use of lighter materials lead to an increase of the structural flexibility. In this case, important issues regarding flight control law design and aeroelastic control must be addressed. This research project is dedicated to (i) the study of integrated dynamic models coupling flight and aeroelastic dynamics and their application to flight control law design; (ii) the validation of these models with flight test data, from the aeroelastic flight testing plattform X-HALE, developed at the University of Michigan; (iii) the development of a new methodology for flight control law design of flexible aircraft.

The exhaust jets of turbofan engines have a major contribution to the noise generated during the take-off of aircraft. The latest generation of engines (UHBPR, of Ultra-High Bypass Ratio) has a significantly higher diameter, and their installation on the vicinity of the trailing edge of the wing can increase drastically the radiated sound due to acoustic scattering. This project address the installation effects on jet noise by numerical simulation and reduced-order modelling, the latter focusing on coherent structures in jets modelled as linear instability waves, or wavepackets.

Today's high-strength and damage-tolerant materials allow for significant increases in load capacity and stress limits in aircraft structures. This research project addresses the application of composites in elongated aircraft wings and focuses on numerical and experimental investigations of the hygro-thermoelastic effects on the structural performance of stiffened composite panels manufactured using co-cured (co-bonded) and adhesively bonded joining technologies subjected to static and fatigue induced delamination. This work is part of the green aircraft platform research proposal under development at EMBRAER.
The motivation and inspiration for the creation of the Laboratory of New Concepts in Aeronautics – LNCA is the opportunity of having a high level research orientation and management support group in the Aeronautical Engineering Division at ITA.
Based on identified technological challenges such as higher energetic efficiency and lower environmental impact air vehicles, visionary concepts in aeronautics are the demand of the future aviation technologies. Research and development drivers and initiatives are oriented towards ecological demands and related affairs.
Several initiatives from government or community funded research programs to international advising and regulation organism provides the guidance and fostering for both academia and industry:
· International Civil Aviation Organization – ICAO (Environmental Report)
· Horizon 2020 (The EU Framework Programme for Research and Innovation)
· CleanSky (Single European Sky environmental objectives)
· NASA/FAA NextGen Programs
The academia is an inherent fertile subtract by its conception and working philosophy. The plurality of knowledge, multidisciplinarity, training and contact with people provides conditions for new ideas, such as an environment-oriented engineering education. In the academia there are opportunities to imprint the culture of innovation and entrepreneurship among the students and faculty staff. The LNCA in the academic environment also allows opportunities for redefining engineering at ITA and the best engineer formation. READ MORE
