SUMMARY:Effect of Poynting-Robertson and Solar Wind drag on Smart Dust in S
 pace
DESCRIPTION:Lecturer:Vinayak Vadlamani\n Faculty:Department of Aerospace En
 gineering\n Institute:Technion – Israel Institute of Technology\n Locati
 on:Classroom 165\, ground floor\, Library\, Aerospace Eng.\n Zoom: \n Abst
 ract: \n Details: \n Due to breakthrough advances in miniaturization\, the
  scale of spacecraft components can now be reduced to the millimeter scale
 . Termed as "smart dust"\, the concept of spacecraft on a chip promises t
 o enable a novel category of such centimeter sized spacecraft to be flown 
 in swarms of hundreds or even thousands. One alternative is to exploit pe
 rturbations like solar radiation pressure (SRP) for orbit control without 
 using artificial forces thus yielding stable equilibrium solutions that co
 uld sustain mission requirements. Previous studies have investigated the 
 effect of Poynting-Robertson and Solar Wind (PRSW) drag for interplanetary
  dust.\nGiven similar area-to-mass ratio to smart dust\, including Poynti
 ng-Robertson and Solar Wind (PRSW) drag could possibly extend the solutio
 n space thereby increasing the span of partial or full equilibrium solutio
 ns for smart dust devices. The inclusion of PRSW drag in the dynamical
  model was studied using averaging techniques based on Gauss Variational 
 Equations.  The study focused on the dynamical behaviour of the relativ
 e perigee-sun angle and its stability as a tool for analyzing long-term ev
 olution. The existence of partial and full equilibria solutions was con
 firmed and the results are discussed in detail. Some trends with respect 
 to different area-to-mass ratio are also presented.
