Advanced Aerodynamic Technologies for Future Green Regional Aircraft
Journal Title: INCAS BULLETIN - Year 2014, Vol 6, Issue 1
Abstract
Future Green Regional Aircraft (GRA) will operate over airports located in the neighborhood of densely populated areas, with high frequency of takeoff/ landing events and, hence, strongly contribute to community noise and gaseous emissions. These issues currently limit further growth of traffic operated by regional airliners which, in the next future, will have to face even more stringent environmental normative worldwide and therefore re-designed to incorporate advanced active aerodynamic technologies. The new concept behind GRA is based on several mainstream technologies: airframe low-noise (LN), aerodynamic load control (LC) and load alleviation (LA). These technologies integrate relevant concepts for hybrid and natural laminar flow (HLC/NLF) wing, active control of wing movables and aeroelastic tailoring for LC/LA functions, passive means (micro-riblets) for turbulent flow drag reduction, innovative gapless architectures (droop nose, morphing flap) beside conventional high-lift devices (HLDs), active flow control through synthetic jets, low-noise solutions applied to HLDs (liners, fences), and to fuselage-mounted main and nose landing gears (bay/doors acoustic treatments, fairings, wheels hub cap). The paper deals with the technological readiness level (TRL) assessment of the most promising technologies and overall integration in the new generation of GRA, as a highly optimized configuration able to meet requirements for FlighPath 2050.
