Sensores e Sistemas

Objectives

Acquisition of relevant knowledge for the analysis and operation of general and aircraft instrumentation systems: - Instrumentation concept; - Metrology concept; - Analysis of the subsystems that constitute an instrumentation system; - Analysis of aeronautical systems, involving instrumentation systems. Part of the last objective will be approached by the students through the elaboration and presentation in a class of 1 (one) synthesis work, about an aeronautical system involving instrumentation systems. There will be 3 (three) experimental works involving components of instrumentation systems, namely sensors and signal conditioning units.

Syllabus

1. Concept, characterization and application of instrumentation systems. 2. Metrological characteristics of a measurement channel. 3. General analysis of the main subsystems of an instrumentation system: sensors; signal conditioning; sampling; data conversion and modulation; recording; streaming; visualization systems. Calibration of instrumentation systems. The importance of time for data correlation. 4. Classification and analysis of the various subsystems constituting the instrumentation system of an aircraft: aerological data measuring instruments; navigation and guidance; approach and landing aids; satellite navigation systems for aeronautical application (ABAS, SBAS and GBAS); fundamentals and use of data buses (ARINC 429, ARINC 629, MIL- STD-1553B, AFDX and IEEE-488). Examples.

Prerequisites

Previous attendance of Programming course and Circuits Theory and Electronic Fundamentals course.

Cross Competence Component

The curricular unit covers the development of transversal competences in Critical and Innovative Thinking, Interpersonal and Intrapersonal Competences (oral communication, self-discipline, perseverance, self-motivation, organizational and teamwork), Information and media literacy (ability to locate, access , analyze and evaluate information) in experimental and synthesis work on a flight test application. The assessment percentage associated with these skills should be approximately 20%.

Laboratorial Component

At the beginning of the lective period, the laboratory component will be used to perform work aiming the obtention of data in the scope of experimental works. At the end of the lective period, the laboratory component will be used for the presentation of part of the synthesis work prepared by the students and about an aeronautical system, involving instrumentation systems. To carry out the experimental and synthesis work on an aeronautical system, involving instrumentation systems, the students will be grouped in groups, promoting cooperation and teamwork.

Programming And Computing Component

To carry out the experimental work, basic programming knowledge is required (C, MatLab or similar software).

Ethical Principles

All members of a group are responsible for the group’s work In any assessment, every student shall honestly disclose any help received and sources used. In an oral assessment, every student shall be able to present and answer questions about the entire assignment and solution.
