Patent Searching and Data


Title:
可変ピッチプロペラ装置及びそれを使用する可変推力航空機
Document Type and Number:
Japanese Patent JP6971262
Kind Code:
B2
Abstract:
A variable pitch propeller apparatus enables a propeller to have different pitch angles in one revolution about the drive shaft. The propellers are coupled to a race that is flexible and actuated into different offset distances by a race-deflector. A race-linkage may extend between the race and the propeller or drive shaft coupler to rotate the propeller to a pitch angle as determined by the offset distance to the race. A race-linkage may incorporate one or more wheels that engages with the race and rolls along the race and about the drive shaft. An aircraft utilizing one or more of the variable pitch propeller apparatus may be able to produce downward thrust for vertical take-off and landing and transition to forward flight. The pitch of the propellers may be changed from take-off to flight to provide the required propulsion for the aircraft.
