Abstract
605,045. Variable-pitch propellers. UNITED AIRCRAFT CORPORATION. Oct. 26, 1943, No. 17683. Convention date, Feb. 3, 1943. [Class 114] In a variable-pitch propeller, a fluid motor having members 54, 65 rotatable' relative to each other is insertable as a unit into the hollow shank of each blade 30, the act of insertion causing the outer member 54 to be operatively connected with the blade. In the form shown, the member 54 contacts the inner surface of the blade at spaced locations 80, 82 on opposite sides of a splined connection 84. There is also a splined connection 66 between the inner member 65 and a member 60 stationary on the hub 10. Each blade 30 is retained in a socket 24 by means of stacked thrust ballbearings 36, 38, 40, 42 comprising elongated grooves and entry holes 44, 48 closed by screw pegs 50, and is held in its operative position by a wedge arrangement 52. The outer member 54 carries a gear sector 88 to engage a blade-synchronising gear 90 adjustable as at 92 by the means described in Specification 594,396. The motor 54, 65 may be of the kind described in Specification 605,063, [Group XXVI], and it may be supplied with pressure fluid by the means described in Specification 560,522.
