The present embodiments relate to a pitch angle blocking device 200 for blocking the pitch angle of a multi-blade rotor 110 that has neighboring first and second rotor blades 112 in circumferential direction 205 that extend from a rotor hub 113 of a rotary-wing aircraft 100 in non-operational mode of the rotary-wing aircraft 100. The present embodiments further relate to a multi-blade rotor 110 of a rotary-wing aircraft 100 that is adapted to receiving such a pitch angle blocking device 200, and to a rotary-wing aircraft 100 with such a multi-blade rotor 110. The pitch angle blocking device 200 comprises first and second attachment means 210 that are configured to be non-rotatably and releasably attached to the first and second rotor blades 112 spaced apart from the rotor hub 113, and a connecting device 230 that non-rotatably connects the first attachment means 210 with the second attachment means 210.
