SUMMARY:Modelling and design of geared mechanical powertrains for aerospace
  - questions of architecture\, simplicity versus complexity\, and future o
 utlook
DESCRIPTION:Lecturer:Christos Spitas\n Faculty:Machine Design\n Institute:N
 azarbayev University\n Location:\n Zoom: \n Abstract: \n Details: \n We an
 alyse some of the main challenges in the geared mechanical transmissions o
 f modern aeroengines such as large-bypass-ratio turbofans\, open rotors a
 nd turboshafts/ turboprops in terms of efficiency\, power density\, weigh
 t\, and reliability down to their casualties and present related models f
 rom recent research. We demonstrate limits to the existing architectures a
 nd\, following basic principles of mechanics\, we discuss how different to
 pologies and interface geometries may help affect force- and torque-transf
 er to produce better efficiency\, material utilisation\, power density and
  light weight\, insensitivity to errors and perturbations\, including fail
 -safety\, and ultimately higher reliability and lower cost. Beyond its str
 ict disciplinary focus\, we use the presented case to raise questions rega
 rding how to approach design effectively at the level of architecture and 
 how to reconcile simplicity\, where one may hope to find design intent\, w
 ith complexity and the realm of "the details"\, where the devil proverbial
 ly resides.\n
