Aerodynamics I

Presentation

Aerodynamics is an area of technical and scientific knowledge that aims especially to analyze and solve problems arising from the interactions of atmospheric air with moving objects. Aerodynamics has traditionally been used in aeronautical engineering as a field of application, but its field of intervention is much wider, also finding application in the automotive industry, in energy systems, in the climate, in the environment and in sport. Examples of applications are pneumatic transport, the action of the wind on structures (buildings, bridges, electrical networks) and the dispersion of pollutants. Providing methods to predict the dynamic behavior of systems and equipment, aerodynamics improves the efficiency of their operation (components of aircraft and wind turbines), increases stability, as well as reducing noise and energy consumption.

Introduction. Relevance of Aerodynamics in Aerospace Engineering.

Review of fundamental concepts of Fluid Mechanics: Newton's law of viscosity. Standard atmosphere. Bernoulli's equation. Similarity and modeling. Drag and lift.

Differential formulation of mass and linear momentum equations. Couette's flow.

Flat-plate flow: Prandtl / Blasius solution for the laminar boundary layer. Integral analysis of Von Kármán. Turbulent boundary layer. Separation and its relation with the pressure gradient.

Lift: Lift generation. Flow around an airfoil. Airfoil features and efficiency. Effect of the finite dimension of the wing. Marginal vortices. Induced drag.

Aerodynamics surfaces for aircraft flight control: Considerations about the control and stabilization of the flight.

Laboratory work: Measurement of speed and pressure. Calibration of the wind tunnel. Determination of aerodynamic forces.

Objectives

The main objective of the curricular unit is to know, understand and apply the principles of Aerodynamics in order to analyze issues in the field of Aerospace Engineering.

Specific objectives:

- Review the concepts of Fluid Mechanics most related to Aerodynamics.

- Analyze problems based on fundamental equations in differential form.

- Analyze flows around wing profiles.

- Understand the mechanisms that cause drag and lift in an aircraft.

- Recognize the importance of experimental modeling in aerospace engineering.

- Provide introductory bases for aircraft design.

Teaching methodologies and assessment

METHODOLOGY OF TEACHING: aims to encourage participation and restore student initiative in the educational process of their own formation. The class structure is divided into theoretical and practical sessions. The theoretical sessions are given remotely through the TEAMS platform, using audiovisual media for the
presentation of the subjects. In the practical sessions, students are confronted with problems / situations, to be carried out individually or in groups, with the help of the teacher, where they can apply the acquired knowledge. These sessions are expected to contribute to a good teacher-student relationship and greater proximity between them.

EVALUATION: carried out in accordance with the ULP Regulation.
