ABSTRACT

In this report different mathematical models for a ballistic missile are derived and simulated for the complete guided control system. In this research work V-2 rocket is taken as an example. Equations of motion are used in SIMULINK to perform simulations. An optimum trajectory is in accordance with launch angle and different burnout parameters. The missile would follow this ideal trajectory in the absence of any disturbance. But in real flight there are various errors and perturbations that make the vehicle not to follow the designated path. To have a successful flight it is required to remove the effect of these disturbances through a properly designed control and guidance system. 6DOF program is simulated which is then incorporated with the pitch orientation controller and a roll stabilization controller and results are simulated in accordance. Inertial navigation mechanization model is constructed in Simulink to propose an ideal navigation model for the rocket system. The controller analysis is performed at various points in the trajectory and the measurements are made in frequency domain. A comprehensive roll control model is designed along with pitch controller using Simulink and various frequency domain plot; bode plots & root locus for analysis.

Aim

...Example 1: Rectangular ThreePointBending
A rectangular specimen is subjected to a three-pointbendingtest. The specimen is 10 centimeters long, 10 millimeters wide (b) and 10 millimeters tall (h). The specimen is placed on two supports that are 5 cm apart (L), and the actuator is applying a force in the exact middle of the two supports (L/2). Immediately before failure, the Instron records...

...depending on its contents, sometimes a new label is added or if the packet contained more than one label (label stack) a label might be removed from the stack or in some cases labels get swap. This process continues until the exit LER is reach at this point the LER removes the MPLS label or label stack and the payload is then handed out to a device or different type of IP network outside of the MPLS domain. In addition, MPLS provides Traffic Engineering (TE) which gives...

...refers to the ability of a material to return to its original shape after the force applied to it is removed. However, at a certain point the material will not be able to resist the force applied to it and the material will plastically deform (i.e. will break and not recover its original shape). This point is called the yield point and the stress applied at this point is called the yield stress. The rate of deformation differs from one...

...Introduction
A bending moment is simply defined as “the algebraic sum of the moments of all the forces which induces bending of an element” (1). The aim of this assignment is to work out the bending moment in a simply supported beam when different concentrated loads are applied to it. A simply supported beam is a structure, usually with a straight profile supported at the ends, often pinned on one side and simply supported or on a roller on the...

...Abstract
A tensile test was conducted on an Instron tensile machine using a 3/16 inch copper rod. Using data acquired stress and strain was calculated and plotted on Excel to analyze stress strain curve. Modulus of elasticity, 0.2% yield stress, ultimate tensile stress and % elongation were also calculated.
Introduction
A tension test is probably the most fundamental type of mechanical test you can perform on material. Tensile...
