Abstract: (I) Research and development of required performance evaluation
In order to derive the performance evaluation criteria for visual observation and flying over third
parties, analysis of the equivalent of class N class of air-classification and the global performance
evaluation criteria analysis of the Ministry of Land, Infrastructure, Transport and Tourism Aviation
Bureau examination guidelines was conducted.
(II) Examination of the method of performance evaluation
 For noise evaluation, noise measurement was carried out using sound power level measurement,
which has become the international standard measurement method in recent years. The reverberation
room method is used for measurement. As a method of drone noise measurement, we developed a
measurement device equipped with a thrust measurement device on a measurement stand that fixes
the drone and compared with the noise measurement of a drone hovering in the air, it is almost ± 1.5
dB error. The same acoustic spectrum data measurement results were obtained.
 Regarding drop dispersion, we developed a drop test device to clarify the drop mechanism of the
drone. The drop test device is a device for receiving a drop of a drone, and each of the height and
width thereof is 10 m × 10 m × 6 m. The drone which has reached the terminal velocity due to the
fall is decelerated to zero velocity at 6 m in height. The termination speed was 15 m / s for almost
every drone. The decelerating acceleration is controlled by the control of the tension of the receiving
device.
 The collision safety evaluation device is a device for evaluating the damage caused by a drone
collision on the head, and is a measuring device having a human head structure called a head
impactor, an impact accelerometer, a load measuring device, etc. Is mounted inside.
(III) Verification of performance evaluation criteria
 For noise evaluation, the sound pressure level characteristics by distance derived from the sound
power level, which is the total sound energy generated by the unmanned aircraft, and the sound
pressure level characteristics by the distance measured in the field are compared. It was shown that
the evaluation of noise performance was displayed stably. From the drop test, the characteristics of
the multi-rotor type unmanned aerial vehicle drones that use a lot of planes revealed the mechanism
of falling like a card. In the collision safety evaluation, measurement of the head impact index (HIC)
used for car collision safety evaluation was carried out, and the value of 220 was obtained in the
measurement of HIC. It was found that this was measured as a small value compared to HIC = 1000,
which is a lethal value in cars.
