Introduction
This practical work is prepared according to the working curriculum on the discipline «Electricity supply of aircraft» for students with training direction 6.051103 «Avionics».
The purpose of this laboratory practical work is to consolidate students’ knowledge, to improve research skills of physical processes that accompany electro energy production and consumption on the board of aircraft (AC), to learn techniques of gathering of networks’ elements and calculation of their parameters.
Laboratory works are carried out in three stages. At the first preparatory stage, that precedes the work in the laboratory, a student must: learn the purpose of the work; study the theoretical aspects of the work, using recommended literature; answer the control questions; prepare laboratory work report, which has to contain the purpose of the work main stages of the task, basic scheme of the stand (in simplified form), paying attention to regulators, form a table for recording the results of the research.
In the second stage, directly in the laboratory, you must learn the stand, find the location of controls and figure out the sequence of their being used, prepare the scheme of the experiment. After professor’s checking of the work done and his instructions, it is allowed to begin experiments. During the researches, you need to write down and analyze results simultaneously in order to avoid errors that may occur due to imperfectness of the experiment or failures of stand.
At the final stage of work it is necessary to make calculations, to draw graphs and charts, to compare the results of experiments with theoretical calculations, to make conclusions regarding the studied processes, to fix them in the statement of work. Answer the test questions and defend the work to the professor.
Only prepared students who completed the first stage of the planned work and have fully executed previous work are allowed for laboratory work.
