In the cockpit of aircraft, one of the essential instruments is theotherwise called badin. It displays the statement of the of the’ against the wing via a tube called Pitot directed facing the air flow and the static pressure thanks to two orifices on the sides of the cabin. It is effective and to indicate the of the’ related to , but the instrument is expensive, bulky and hinders aerodynamics. When it comes to small drones, measuring the air pressure on the aircraft is therefore rudimentary, or even non-existent.
This is why, to reinforce flight safety, especially during the take-off and landing phases, scientists from thein the United States, have developed a revolutionary. It can both indicate real-time air pressure and wind direction; it allows by the games of algorithms to estimate more precisely the consumption of of the aircraft. The measuring instrument was designed using so-called “intelligent” materials. The detects pressure variations and reacts to deliver flight information.
A sensor made of “intelligent” material
The research team used aelectric called polyvinylidene fluoride (PVDF). This is what is found in the envelopes of the batteries . the has the advantage of being able to generate energy when pressure is applied to it. It is precisely this pressure that allows both to feed the and also to measure the of the against the .
The PVDF sensor is directly integrated into the profile of the wing, which reduces. To determine the direction of the wind, the sensor is associated with a small compass digital. It measures the orientation of the airfoil relative to the . This type of sensor could be implanted both in balloons or planes, but also on and even their blades, to improve their efficiency.
