Abstract
495,309. Thrust indicators for propellers. ALDERSON, H. J., and MILL, T. G. March 8, 1937, No. 6806. [Class 106 (ii)] Means for measuring the thrust of an aircraft propeller comprises making the propeller shaft slidable longitudinally, and in mounting upon it piston means which acts upon separate volumes of fluid, controlling separate pressure indicating devices, so that the thrust exerted on the shaft in either direction is indicated. A cylindrical non-rotatable casing 15 having annular fluid chambers 16, 17 at each end has a longitudinal bore for the propeller shaft 18. Annular pistons 21, 22 mounted on the shaft 18 are rigidly connected at the exterior of the casing 15 by rods 23, 24 which can be adjusted to ensure proper co-ordination of the pistons. The rods 23 24 pass through clearance holes in ftanges on the casing 15 to prevent the pistons rotating. The propeller shaft is fixed at one end to the propeller 27 and splined at the other end 28 to the engine shaft 29. The propeller shaft carries two thrust faces 25, 26 which are located adjacent the end face of pistons 21, 22, and impart thrust through the medium of balls 19, 20. Pipes 32, 33 connect chambers 17, 16 to pressure tanks 30, 31 carrying pressure gauges 34, 35. Branches 36, 37 may connect to recording devices.
