Abstract

The invention discloses a rotor hub lifting system and a control method thereof. The rotor hub lifting system comprises a propeller hub, a propeller hub spindle, a rotary spindle, a movable ring, a first hydraulic push rod, a second hydraulic push rod, a self-locking ring and at least two self-locking clamps. The propeller hub is arranged at the top end of the propeller hub spindle, the movable ring is fixed to the rotary spindle, the rotary spindle is hollow, and a body of the propeller hub spindle stretches into the rotary spindle; one end of the first hydraulic push rod and one end of the second hydraulic push rod are fixedly connected with the movable ring and the other end of the first hydraulic push rod and the other end of the second hydraulic push rod are fixedly connected with the propeller hub so that the height of the proper hub can be adjusted; the self-locking ring and the self-locking clamps are used for locking and unlocking connection between the propeller hub spindle and the rotary spindle. During work, unlocking is carried out through reverse rotation, and after the propeller hub ascends, locking is carried out through forward rotation. It is guaranteed that the output power of an engine is transmitted while the propeller hub ascends and descends, the structure is simple, and system safety is good.

Description

technical field [0001] The invention relates to the field of flying vehicles, in particular to a rotor hub lifting system and a control method thereof. Background technique [0002] Since the first flying car came out in 1917, people have begun to explore a lot of flying cars. Over the past century, inventors and aviation enthusiasts have designed a variety of flying cars with excellent performance. Nowadays, urban traffic congestion is becoming more and more serious, and the traffic accident rate is also high. Therefore, countries are competing to develop flying cars. Research in this field is becoming more and more important. At present, hundreds of flying car patents have been obtained worldwide, and a variety of Flying prototypes, prototypes developed by a small number of countries have been put into small batch production. The development of flying cars has become the general trend. However, the current mainstream flying car with a rotor system in the world has a roto...
