Abstract(s)
Acting as a bridge for the development of the aeronautics sector in the European
Union, the Clean Sky project is being developed in partnership with leading European
manufacturers of aircraft and their components. Taking into account all the
environmental problems addressed during the recent past, this project has the goal of
revolutionizing the industry through the construction and operation of aircraft with a
low environmental impact. Consequently, the development of this dissertation focuses
on the Green Rotorcraft (GRC2) project that is part of the mentioned European
programme, which aims to shorten the time to market for new solutions tested on
heavy-sized utility aircraft, aerodynamically improved to reduce fuel consumption and
consequent emissions.
The present work shows, through a literature search focused on guidelines and
studies for active and passive control methodologies, a theoretical review of methods to
reduce the parasite drag of the fuselage and non-lifting rotating systems with the
objective to implement them on heavy-sized helicopters, which can ensure the
achievement of the primary objectives established by the European Commission for the
Clean Sky programme. Consequently, design guidelines are shown with practical
examples demonstrated, to give evidence and enable the development of this project.
An analytical work is performed in this thesis, divided into two distinct areas:
Active Horizontal Stabilizer, to trim the fuselage; and Cooling Systems, improved to
reduce their net ram drag. Optimization solutions are presented in this research,
showing the theoretical benefits obtained from the implementation of such changes.
Description
This work was made possible through the collaboration between University of
