Explanatory note to the diploma project “Identification of the vibratory error of the navigation accelerometer through the bench tests” consists of __ pages of text, __ illustrations, __ tables, __ bibliographic references.

The aim of the project is to develop a method of determining the additional constant component of the output signal of the navigational accelerometer under the action of deterministic and random vibrations on it.

There is the comparative analysis of existing methods of determining vibratory error. The mathematical model of vibratory error was obtained on the basis of the metrological model of the accelerometer. The method for identifying the coefficients of this model was formed and vibrational stand for testing was also developed.

The practical part of the project contains the test of three accelerometers (AL-15, AL-1, A-17) using existing and own methods. The comparative analysis of the results confirms the effectiveness of the developed methodology.

Keywords: vibratory error, vibratory acceleration, vibrational test, vibrational stand, navigation accelerometer, metrological model.

Explanatory note to the diploma project "Quadrotor of increased reliability, continuing flight during the failure of propeller-driven group" consists of pages of text, illustrations, tables, bibliographic references.

 

The aim of the project is to increase the functional reliability of the quadrotor with the refusal of one or two propeller-driven group (PDG).

 

The following methods are used: redundancy. A way to increase the functional reliability of technical objects and systems software reserve, a method of mathematical modeling. The mathematical model of motion of the quadrotor, as well as the dynamics equation, is supplemented with the forces of aerodynamic resistance. An algorithm for the transition of a quadrotor model from four PDG to two with the refusal of one PDG was developed. The obtained results allow the refusal of one or two PDG to stabilize and extend the flight of the quadrotor for its trouble-free landing.

 

Key words: reliability, quadrotor, propeller-driven group, flight crash.

Explanatory note to the diploma project "Mini ultraviolet pico polarimeter for the studying stratospheric ozone layer of the Earth" consists of  ___ text pages, ___ illustrations, ___ tables, ___ bibliographic references.

 

The aim of the project is to create structural and functional diagrams of the device, create layout for testing in the laboratory.

 

The following methods are used: algorithmic processing of measurement results. The developed algorithm for processing the measurement results makes it possible to determine the degree of ozone polarization. The obtained results let estimating the state of the ozone layer of the Earth.

 

Key words: ultraviolet, polarimeter, ozone layer.
