The invention relates to an electronic safety system for automatic launchers of pilot-free planes, meant to protect persons located in front of the launchers. According to the invention, the system consists of a sensor (S) of PIR (Passive InfraRed) type placed on the frontal side of a pilot-free plane launcher, an antenna (ANT) and an amplifier detector (A), which detects and amplifies the plane launching signal, a logic gate (ŞI1), by means of which the launch is blocked/validated, a logic inverter (I), a logic gate (ŞI2) and a loudspeaker (D), by means of which a warning signal is emitted during the entire period in which the launch command is active and the presence of a person is detected by the sensor (S), a servo-mechanism (SERVO) for actuating a trigger (T) of the launcher, which unblocks the pilot-free plane launch, if the presence of a person in front of the launcher is not detected. |
