Volume 5, Issue 3 , July 2008, , Pages 139-144

Abstract
  In some aerospace vehicles, the tracking sensors which act in a tracking loop as stabilizer are mounted on a two degree of freedom gyro. The gyro must align its rotor axis with the line of sight in order to remove tracking errors. The tracking precision and sensitivity are functions of the gyros performance. ...  Read More

Dynamic Stability of Step Beam Carrying Concentrated Masses under Follower Force

M. Sohrabian

Volume 4, Issue 4 , December 2007, , Pages 1-6

Abstract
  This paper investigates the dynamical behavior of an assembled beam like structure with tip masses modeling a two stage space rocket structure. The beam like structure is composed of two beams connected together carrying two masses at the free ends to model the payload, and the stabilizing fins mass ...  Read More
