Sensors may soon be able to tell aircraft maintenance engineers just where the aircraft needs attention. A joint project between the Vienna University of Technology and EADS Germany may see a sensor network being developed throughout the body of aircraft.
The sensors, developed by the Institute of Sensor and Actuator Systems at Vienna University of Technology, are self powered and able to report to aircraft maintenance crew just where to work, bringing down maintenance costs by saving time. The sensor network will be independent from the electrical wiring of the aircraft and thus will not be affected if it malfunctions.
The sensor has a small water tank and thermoelectric generator for its power needs. The electricity is generated due to the temperature difference between the cold air in high altitudes and the air close to the ground said Dominik Samson of EADS.
Electricity could also be generated as the aircraft comes in to land. This method of energy generation for the sensors will be much more economical than relying on regular batteries to power them. The sensors would also be able to, at an advanced stage, tell the cabin crew which passenger has fastened their seat belt, does not have a table in the upright position or does not have the seat upright.
