SUMMARY:Development of Adaptive Cycle Micro-Turbofan Engine for UAS Applica
 tions
DESCRIPTION:Lecturer:Michael Palman\n Faculty:Department of Aerospace Engin
 eering\n Institute:Technion – Israel Institute of Technology\n Location:
 Classroom 165\, ground floor\, Library\, Aerospace Eng.\n Zoom: \n Abstrac
 t: \n Details: \n The current research is focused around the development o
 f a variable cycle micro-turbofan engine an existing micro-turbojet with l
 ess than 1kN thrust. The project involves the conversion of a single spool
  micro turbojet via integration of a fan\, a continuously variable transmi
 ssion (CVT) and a variable bypass nozzle.\nAs the micro gas turbine market
  suffers from restrained design costs\, in order to shorten the design pro
 cess to a minimum\, the aspiration is to entail as few changes as possible
  to the core design. The solution\, analyzed in the scope of this work\, s
 ignificantly improves maximum thrust\, reduces fuel consumption by maintai
 ning the core independently running at its optimum\, and enables a wider o
 perational range\, all the meanwhile preserving a simple single-spool conf
 iguration. Moreover\, the introduction of a variable fan coupling would al
 low real-time optimization for several operational modes. Small gear ratio
  would yield a lower fan bypass ratio\, and therefore performance resembli
 ng a turbojet suitable for high speed flight\, whereas large gear ratio wo
 uld alter the engine cycle towards a modern turbofan\, which provides impr
 oved fuel consumption during loitering and take-off. Thus\, a small UAV eq
 uipped with this high-performance and cost-effective variable-gear-speed t
 urbofan\, would be able to operate efficiently in both "fly-fast" and "loi
 ter" modes.\nIn addition\, the acquired thrust increase translates into gr
 eater take-off weight\, while independently varying bypass area and fan sp
 eed enables transonic flight and general reduction in fuel consumption. Th
 e combination of these effects yields an increase in range and loiter time
 . The aircraft architecture equipped with this adaptive engine can enable 
 realization of unique missions that were prior unattainable or required di
 fferent UAV propulsion systems. These unique characteristics are explored 
 in a set of realistic scenarios.
