Patent number: 10851805Abstract: An actuator assist apparatus for use with an actuator has a housing and a piston member slidably disposed in the housing. The piston member divides the interior of the housing into a first fluid chamber and a second fluid chamber. The actuator assist apparatus is configurable between a first, primed, configuration and an activated configuration. A force applicator is configured to store energy when the apparatus is in the primed configuration and release the energy to move the piston member relative to the housing. Movement of the piston member applies a force which assists in urging the actuator towards an extended configuration, thereby reducing the minimum operating pressure of the actuator.Type: GrantFiled: May 25, 2017Date of Patent: December 1, 2020Assignee: GE OIL & GAS UK, LTD.Inventors: Graeme Alexander Thomson, Peter John Davey

Patent number: 9956653Abstract: A method of manufacture of a cladding body for an edge of an aerofoil, the method including the step of providing a core member shaped to include an elongate recess portion for mounting on the edge of the aerofoil, the elongate recess portion being shaped across its width to define a smoothly curved concave surface. A support member is provided; the support member has a support portion for complementary engagement with the recess portion. Both the support member and the core member are arranged between a pair of opposing membranes. The core member is bonded to each of the pair of membranes to form an intermediate cladding body, wherein the recess portion of the core member is arranged to engage, at least during the bonding step, the support portion to be supported thereby. At least the membranes are shaped using a hot forming process.Type: GrantFiled: January 8, 2015Date of Patent: May 1, 2018Assignee: ROLLS-ROYCE plcInventors: Craig Wilson, Michael John Davey, David Cowherd, Stephen John Wilkinson

Publication number: 20090173827Abstract: A method for monitoring the integrity of a permeable structure that is disposed in an environment containing a fluid at ambient pressure is provided. At least one cavity is formed in or on the permeable structure. A source of first fluid is provided at a first pressure greater than the ambient pressure. The cavity is coupled to the source through a high-fluid-flow impedance to establish a flow of the first fluid through the permeable structure via the cavity. A rate of flow of the first fluid through the permeable structure is allowed to stabilize to a steady-state rate. A change in the steady-state flow rate of the first fluid through the permeable structure is monitored.Type: ApplicationFiled: February 23, 2009Publication date: July 9, 2009Inventor: Kenneth John Davey
