System of measurement and recording of touch-down parameters type AVI-a

System AVI-a of measurement and recording of the touch-down process, elaborated by Adaptronica Sp. z o.o., performs the measurement of vertical speed of an aircraft and its distance from runway during touch-down. The system enables the user to assess the loads acting on the aircraft structure during landing.

The measurement of vertical speed of the aircraft and its distance from runway utilizes a transmitting-receiving ultrasonic head as well as targeted aquisition and signal analysis. The transmitting-receiving head, operating in the range of ca. 40 kHz, allows for improving the ratio of the analyzed signal to noise level generated by the aircraft in flight.

The level of loads acting on the aicraft structure during touch-down is measured by an accelerometer placed in a preselected spot on the aircraft.

Thanks to aquisition and storage of measurement data on SD card, the system AVI-a provides better assessment of pilot skills based on recording of the touch-down process. It also enables monitoring of structural fatigue.

AVI-a can be applied on ultralight and light aircrafts and can be also adapted for unmanned aicraft vehicles.

The advantages of the AVI-a system are the following:
  • possibility of assessment of pilot skills based on recording of the touch-down process,
  • better evaluation of structural fatigue due to repetitive loads,
  • possibility of assessment of aircraft failures,
  • storage of data on SD card,
  • waterproof ultrasonic head,
  • autonomous power supply,
  • low power demand,
  • compact dimensions and low mass,
  • easy mounting.

The application of the AVI-a system on a specified airplane requires user-producer interaction.

We look forward to cooperation
