Abstract

452,611. Screw propellers. FAIREY, C. R., c /o Fairey Aviation Co., Ltd., Cranford Lane, Hayes, Middlesex. Aug. 24, 1935, No. 23786. [Class 114] An air-screw blade is provided with a hollow central tubular back bone member to which is attached the sheet metal fairing and this back bone is formed of coaxial laminated tubes of different length. A back bone of hollow tubular form is constituted by three tapered steel tubes a<1>, a<2>, a<3> of circular crosssection, the root ends being co-terminous and being riveted to a sleeve d for fixation in the boss sockets. The outer blade surface is constituted by a sheet metal fairing b, it being secured by rivets c to the tubular back bone. In an alternative form the section of the back bone is of channelled form beyond the root portion, the parts a<4> a<5>, a<6> having gaps between them and in this case the fairing is affixed by welding m. In another form the tubular member is secured to channel members n by rivets o which are in turn secured to the fairing by rivets p. The nose portion may be stiffened by additional corrugated ribs q riveted to the fairing. In one construction the fairing b stops short of the tip at z and the outer tip portion y is separately provided and secured thereto. Specification 394,799 is referred to.
