Overview

This course offers the student: This course provides the student with general information about marine propulsion units and their classification. This course studies the movement of the ship’s movement from the engine to the propeller. It aims to introduce the student to the concept, classification, requirements and functions of marine propulsion units (the machine), and to identify the speeds, loads, forms, capabilities, moments and competencies of the ship. How to draw curves and calculate the efficiency of the propulsion unit, and the general methods for designing the propulsion units represented by the main propulsion engines of both types, which are diesel engines; gas turbine engines; Then study the characteristic curves for each of them, and know the difference between a single and multi-engine propulsion system, study the time and quality consumption of fuel and calculate the sailing range. Then, the system components represented in: the main propulsion engines of both types, connections of all kinds, gearboxes, drive shafts, and propellers, as well as studying the movement system and its distinctive curves, then identifying the most important propulsion systems used in the marine field and their types, and the installation of the propulsion system and identification About its most important components in both Arabic and English. Then identify the movement system and its relationship to the parts of the propulsion system and draw the curves of joint work with the parts of the propulsion system, And the joint work between the parts of the movement system and its relationship to the propeller with a fixed and moving step, and the relationship of the ship structure to the propeller, and the effect of external conditions and the phenomenon of cavitation on the propeller curve, and the study of the causes of cavitation and its effects on the propeller, and methods of treatment and calculation.

Intended learning outcomes
