Propulsion Systems

Recommended Prerequisites

Mathematical Analysis I, Mathematical Analysis II, Mathematical Analysis III, Physics, Thermodynamics, Fluid Mechanics, Complements of Thermodynamics and Fluid Mechanics, Heat Transfer, Heat and Mass Transfer

Teaching Methods

The methodology followed in the lectures consists first to motivate the student and secondly to present the subject in an understandable way using audiovisual media. It is aimed to develop the student analysis and simulation capacities of propulsion systems and its components using fundamental laws.

In theoretical and practical classes is performed the analysis and solving of theoretical and practical engineering problems where the theoretical knowledge is applied.

Evaluation method:

2 Numerical simulation practical work reports, 15 %

8 Problem solving reports, 20 %

Midterm Exam or Exam, 65 %.

Learning Outcomes

In this course, the student acquires knowledge about the components, the arquitecture and the operating principles of different propulsion systems used in terrestrial vehicles and aircraft. The equations for the calculation of the power requirements of terrestrial vehicles are presented. Some normalized driving cycles for terrestrial vehicles and the equations that allow the modelling of the cycles for the energy consumed, the fuel consumed and the emission of pollutants are presented. Different components for storage of electric energy, their principles of operation, their performance parameters and their limitations are presented.

The student develops skills for modelling the operation of propulsion systems, based on the fundamental laws such as the conservation of energy, the forces that act in the vehicle and the 2nd law of Newton, and applying the knowledge acquired.
