    Abstract: An impedance shaping element (or more simply, an impedance shaper) physically alters or shapes the mechanical impedance of a drive system as it appears from an interface and facilitates use of feedback control to improve performance by altering or shaping a dynamic coupling between an interface and a control system. For example, the impedance shaper can be used to adjust a coupling value from a first value to a second different value. In one embodiment, an impedance shaper controls the compliance, damping and inertia characteristics of fluid within a fluid path.

    Abstract: A gas-oil pressure accumulator having a load-bearing structure of composite material, suitable for aircraft hydraulic circuits. The accumulator is formed of a cylindrical body with closed ends, at least one of which is composed of a convex cap. A piston slideable in the cylindrical body defines two chambers, one adapted for containing hydraulic oil and the other adapted for containing gas under pressure. The walls subjected to internal pressure are formed with an internal core of metallic material of small thickness, and are provided with a facing of composite material, composed of high-strength fibres impregnated with synthetic resin, adapted for resisting the loads due to the pressure, which facing of composite material extends at least over one of the end caps of the cylindrical body, the winding of the fibers being continuous and without the superposition of consecutive turns in any one layer of turns, with winding angles differing from the angles corresponding to the equilibrium path of the stresses on the surface of the cylindrical body itself.

    Abstract: A reduced weight and repairable piston accumulator. The accumulator includes a load bearing metallic cylinder with removable end caps secured thereto with slip flanges for allowing repairability and for achieving the required cycle life. The cylinder serves as the surface on which the piston slides and is designed such that it sustains the axial stress induced by pressurization of the accumulator. A composite over wrapping is designed such that it sustains the stress in the hoop (radial) direction. A stress transitioning bushing can be provided for transitioning hoop stresses between the overwrap and the slip flange. When combined with the cylinder, the fibers of the composite wrap will not be placed in shear and thus will not fatigue in the same manner as some prior art designs.

    Abstract: A pressure vessel for receiving at least one fluid medium has a first shell (1) and a second shell (3) at least partially encompassing the first shell (1). The first shell (1) has, at least at one of its ends, a collar portion (5) having a securing element (15) that forms an opening (13) for supplying and discharging the medium. A support element (19) in the form of a split ring surrounds the opening (13), is provided inside the container and has a contact surface (39) adapted to the curved shape of the first shell (1) inner side attached to the collar portion (5). The contact surface is able to be pressed onto the first shell inner side attached to the collar portion (5). The contact surface is able to be pressed onto the first shell (1) using a pressing device (43, 45).
