Abstract: It is proposed to create a tool for a specific maintenance task, which is carried out in the periodic inspection of several aircrafts. The task is described in the maintenance of the HT-29 military tactical transport helicopter (trade name NH90, manufactured by Airbus Helicopters). The maintenance task consists of checking the condition of the landing gear shock absorbers. It is necessary to measure the temperature of the shock absorber shaft, the displacement (length) of the cylinder, and the pressure of the gas it contains. It will be carried out on each of the three axes available in this aircraft. As a project, it is proposed to create a device, which due to its morphology can be placed (by means of a clamp or similar) on the axis of the shock absorber, so that from that position, it can measure the temperature of the cylinder with infrared sensor, the displacement of the cylinder with an ultrasonic probe, and finally send this data wirelessly to another terminal, where the readings can be consulted, in addition to assessing whether or not they are correct. This last device will indicate the valid pressure range to be checked by external elements. Finally, it will store the readings on an SD card.
