Title Study on the calculation and design of the rotary inertia of the terminal sensitive projectile without parachute
Abstract
The design of rotary inertia is of great significance for the realization of stable
scanning of the terminal sensitive projectile without parachute.This paper mainly
studies the calculation and design of the rotary inertia of the terminal sensitive
projectile without parachute and wing.Firstly,the article establishes a TSP model
with one mass ,and then uses physics formulas and theorems such as the parallel
axis theorem of susceptibility to derive the formula of rotary inertia around an
arbitrary axis of the TSP model with one mass ,then derives the formula of rotary
inertia around an arbitrary axis of the TSP model with two masses.Secondly,the
article analyses the force of the TSP in the stable scanning .In the stable
scanning,because the resultant force and moment of the TSP is 0,so we can establish
the equations and write a program .In this program,we should set the scanning
angle,the quality of two masses and the coordinate of one mass suitably then we
can find out the only solution--the coordinate of another mass.Finally,we feed
all known qualities into the formula of rotary inertia and then,here comes to the
rotary inertia of the terminal sensitive projectile without parachute and wing.
