Introduction to sensor fusion

Many researchers would agree that the first steps into experimental aircraft control analysis are sometimes the hardest because young researchers must close the gap between the theoretical knowledge and the know-to-how on the praxis. The main difficulties in a practical set-up involve determining the required instrumentation, programming suitable communication protocols…

Practical example on data science and aeronautics

Airplanes have multiple sensors that help pilots measure air speed, air pressure, and altitude. These sensors can be used to collect crucial data like temperature, moisture, and pressure in different parts of an aircraft. Nonetheless, the absence of explicit models to include all the measurable properties had yield to a…

Boeing: high lift control system

As technology advanced, Boeing 777 was the first aircraft from the company to include a full authority fly-by-wire system. That is, utilizing a flight-control system in which controls are operated electrically rather than mechanically. The main advantages that this maneuvering system provided to Boeing were reduced weight, easer separation of…

Boeing: from redundancy to fault tolerant control

Boeing on the other hand, follows the fault tolerance through detailed hardware redundancy. It is achieved by providing two or more physical copies of a hardware component. Boeing’s redundancy core lies on the triple redundancy of hardware resources for the Flight Control Computer. FCC are configured as a Triple Modular…

Airbus: the tale of fault tolerant control

Flight Control Computers (FCC) take the pilot orders transmitted to the actuators by an arrangement of mechanical components to provide enhanced maneuvering characteristics. The control surfaces follow the FCC commands through electrical connections. It implies that, the aircraft reliability is also dependent on the FCC performance. …
