    摘要: A method of determining the lift generated by a lift-generating member is presented. The lift-generating member being coupled to a component within the lift load path with the lift load path component experiencing strain as a result of the lift generated by the lift-generating member. The method involves the steps of coupling at least one strain measurement means to the lift load path component, obtaining strain measurements from the strain measurement means, and calculating the lift generated by the lift-generating member from strain measurements.

    摘要: An engine test system includes a base constructed and arranged to reside at a fixed location. The system further includes an engine support member constructed and arranged to concurrently support an engine and move relative to the base. The system further includes a linear transducer having (i) a first portion supported by the base, (ii) a second portion supported by the engine support member, and (iii) a circuit adjacent the first and second portions. The circuit is constructed and arranged to provide a linear transducer signal identifying an amount of linear compression and/or tension between the engine support member and the base along a predefined direction. When the linear transducer resides at a break in station, such an embodiment provides a simple, low cost mechanism which is capable of providing a horsepower measurement for every engine passing through the break in station.

    摘要: A system and method use an optical strain gage to measure engine bearing thrust. Reflecting surfaces, or mirrors, encapsulated in a housing, are separated by an initial gap. An incoming fiber receives light from an interferometer and transmits the light to the reflecting surfaces, which then reflect the light back to the interferometer. An engine load is introduced to a bearing element bonded to the housing, and the rotor thrust into the bearing element causes a change in the initial gap. An increase in the initial gap indicates tension and a decrease in the initial gap indicates compression.

    摘要: In present day propeller driven aircraft, the engine is mounted on slightly resilient engine mounts which in turn are secured to the aircraft fuselage. Under propeller rotation, the developed thrust causes the engine housing to move slightly forward relative to the fuselage due to the resiliency of the mounts. The amplitude of the engine displacement is directly proportional to the magnitude of the thrust, and the present invention measures this displacement and converts it to an indicated value of thrust. A displacement or force balance transducer, remote from the engine proper, is mounted behind the engine on the engine compartment firewall. A dimensionally stable compliant tensile member such as a steel cable having one end bolted to the engine housing and the other end connected to the spring loaded moveable core of the transducer transmits the engine displacement to the transducer. Securing the cable to an existing stud on the engine housing is a simple mechanical connection, and requires no modification to the engine itself.
