VARIABLE SPEED AIRCRAFT TRANSMISSION

摘要

A variable state planetary shifting transmission 401 can include an input shaft 501, an output shaft 513; and a planetary system 419 having a sun gear 511 associated with the input shaft, a planetary carrier 507, and a ring gear 523 associated with a ring housing 509. The transmission can include an overrunning clutch 413 operably coupled to the planetary carrier. The transmission can include a clutch assembly 517 coupled to the planetary carrier. The transmission is capable of changing the speed ratio between the input shaft and the output shaft by selective engagement of the clutch assembly against the ring gear which can cause either the freeing or locking of the planetary carrier by the overrunning clutch.
