variable-pitch adj. of or pertaining to †(a) a propeller in which the blades are shaped so that the pitch varies along their length (see quot. 1912) (obsolete); (b) a propeller, fan, etc., in which the angle of the blades with respect to the direction of air flow can be adjusted, esp. while they are in motion.

1912 Ledeboer & Hubbard tr. Duchêne's Mech. of Aeroplane vii. 197 M. Drzewiecki, with the idea of getting the maximum efficiency out of every part of the propeller, varies the pitch at each point so that the actual angle of incidence is everywhere the optimum angle. Propellers of this kind are known as variable-pitch propellers, and are consequently no longer true screws.

1918 W. H. Berry Aircraft in War & Commerce vii. 91 Worked in combination with a variable pitch propeller the gearbox would allow the pilot a range in power and speed.

1919 H. Shaw Text-bk. Aeronaut. xi. 147 In the variable pitch type, the blade angle is varied continuously from the hub outwards in such a way that the slip column of air is forced backwards with a velocity which is uniform throughout.

1952 A. Y. Bramble Air-plane Flight x. 153 The problem of providing the essential static thrust for take-off found its solution in the variable-pitch propeller.

1971 Daily Tel. 4 Nov. 3 (advt.) Variable pitch engine cooling fan. Large range to fit most popular cars.

1974 Encycl. Brit. Micropædia I. 375/1 Additional features have been engineered into variable-pitch propellers; first, the ability to feather..a propeller on an engine stopped in flight.
