OSKBES MAI AV-15-D2 variable-pitch reversible propeller

AV-15-D2 variable-pitch propeller is designed to create the forward and reverse thrust. Specially designed blades allow realizing the value of reverse thrust up to 50% from the forward one. Unlike traditional propellers, AV-15-D2 has an increased operation speed of the pitch control system. The minimal full reversing time of the blades is 0.5 seconds. This enables it to control and stabilize the aircraft with multi-engine powerplant. To exclude the vibrations at the transient mode and at oblique flow, each
