Design and Dynamic Analysis for Vertical and Horizontal Cylindrical Body in Reentry Flight

Morteza Tayefi; Ramin Kamali Moghadam

Volume 15, Issue 3 , September 2022, Pages 1-9

Abstract
  To create drag and reduce the speed of space payloads in the phase of entering the atmosphere, the payload body itself can be used as brake mechanisms without using additional tools. The approach analyzed in this paper is the separation of the nose and then the stability of the cylindrical body in horizontal ...  Read More

Design of an Nonlinear Extended State Observer to Estimate Unmeasurable Information on the Problem of Flying Objects Guidance

Mahsa Javaheripour; Ahmad Reza Vali; Vahid Behnam Gol; Firouz Allahverdizadeh

Volume 15, Issue 3 , September 2022, Pages 67-78

Abstract
  Proportional navigation is one of the most widely used methods in guiding flying objects. This method requires the rotation rate of the line between the interceptor and the target to calculate the guidance command. For a variety of reasons, including cost savings, simple sensors are used to measure tracking ...  Read More
