20830012 - SENSORS FOR AEROSPACE

The aim of the course is to provide students with in-depth theoretical knowledge on: understanding the operating principles of the main sensors used in the aerospace sector; learning advanced measurement techniques, such as ultrasound, vibrational, sonic, and innovative methods like impact and cross-correlation techniques.
Students acquire critical analysis and problem-solving skills for identifying and solving issues related to the use of sensors in aerospace applications, and ability of analysis of data collected by sensors to optimize performance and prevent failures.

Programma

Sensors for Onboard Instrumentation
These sensors are directly installed on aircraft and provide essential data for:
- Safety: monitoring critical parameters such as airspeed, altitude, position, attitude, and cabin pressure, ensuring the safety of aircrafts.
- Navigation: sensors such as GPS and IMU (Inertial Measurement Units) provide precise navigation, delivering information on the aircraft's position, velocity, and orientation. Space navigation sensors: star trackers.
- Environmental monitoring: measurement of internal and external conditions (e.g., temperature, humidity, air quality, gas sensors, radiation, dust, and micrometeorites) and detection of potential hazards such as fire or smoke.
- Operational efficiency: optimization of fuel consumption and monitoring of potential anomalies to ensure the aircraft operates within safe and efficient limits. flow and level sensors.
- Autonomous radio sensors: LIDAR and RADAR (altimeters and for navigation).
- Sensors for earth and space observation: spectrometers, infrared sensors, and high-definition cameras.

Sensors for Structural Control
These sensors are used both in-flight and on the ground to verify and monitor aerospace structures.
- Vibration Sensors: Detect structural vibrations to prevent damage during launch or operation.
- Strain Gauges: Monitor mechanical stresses on the vehicle's structures.
- Non-Destructive Testing: Technologies such as ultrasound, sonic, vibrational, and ultrasonic techniques are used to inspect the integrity of structures without compromising their functionality.
- Technological Innovations: Advanced techniques, such as energy measurements, impact tests, or cross-correlation, and MEMS, are applied to aerospace materials to ensure reliability and safety.
