Abstract
1,023,303. Measuring engine thrust. JOHN CURRAN Ltd. Nov. 14, 1962 [Nov. 17, 1961; June 7, 1962], Nos. 41179/61 and 22005/62. Heading G1W. An engine test bench for testing the thrust of jet engines comprises an engine carrier 1 (Figs. 1, 2) on a platform 2 having two converging arms 3, 4 with a cross beam 18 and supported on a fixed base 5 by flexure straps 6, 11. A hydraulic capsule 16 is supported on post 14 fixed to the base 5, and a similar capsule 17 is fixed to the cross beam 18 of the platform 2. The capsules have movable heads, 16b and 17e (Fig. 3) respectively, which abut one another, the head 16b having an adjustable part 16e. Movement of the platform 2 by the engine thrust moves a housing 17c of the capsule 17 and reduces the volume of a chamber 17a between the head 17e and the housing 17c thus actuating a Bourdon tube instrument 19 which indicates the engine thrust. The head 16b is not displaceable by the force exerted upon movement of the platform 2 so long as the volume of a hydraulic compensating circuit (Fig. 3) remains unchanged. This circuit comprises a compensator device 21 having a variable volume chamber 22 defined by a fixed housing part 23a and a diaphragm 24 bonded to a rigid block 25. The block is bolted to a piston 26 movable in a chamber 31 in a housing part 23b and is coupled to a motor (Fig. 4 not shown). When the platform 2 moves due to the engine thrust a projection thereon engages a switch to start the motor which moves the piston 26 so as to reduce the volume of the chamber 22. Liquid is thereby forced through a pipe 140 to the space 16a which causes the head 16b to push the head 17e toward the housing 17c. But, as the housing is rigidly connected to the beam 18 of the platform 2, the platform moves to its original position from which it was moved by the engine thrust, and the relative displacement of the head 17e and housing 17c remains unchanged. During this return movement of the platform therefore the instrument 19 still indicates the engine thrust. The calibration and setting up of the test bench is described wherein a hand operated device 42 (Fig. 3) is provided which is similar to and is arranged in parallel with the device 21. Instead of the hydrostatic capsule 17 as a load cell a hydro-dynamic load cell may be used (not shown).
