  • Balance for measuring the thrust of a turbojet engine
    Patent number: 5170662
    Abstract: A balance for measuring the thrust of a turbojet engine comprises a movable frame suspended by flexible suspension strips from an interface structure fixed to the ceiling of a building housing the balance, an adaptor by which the turbojet engine is mounted to the movable frame, and a thrust measuring system fixed to the interface structure and connected to the movable frame to measure the longitudinal force exerted on the frame by the turbojet engine when the engine is in operation. The flexible suspension strips consist of two front suspension strips disposed in a transverse plane symmetrically one on each side of a longitudinal median plane through the balance, and one rear suspension strip disposed transversely in the longitudinal median plane of the balance, these three suspension strips providing an isostatic suspension of the movable frame from the fixed interface structure.
