The European industry is currently a world leader in aviation and to maintain its leading position and competitiveness in the dynamic global market, Europes industry must develop quickly and efficiently high quality products by meeting time-critical market demands and customers needs. Industrial competition is becoming fiercer not only from established regions, such as the USA, but from new emerging challengers, such as Brazil, Canada, etc. Technological leadership and innovation is becoming the major competitive differentiator, most notably in terms of costs, and environmental performance. The market demands shorter cycles of new technology integration and, on the other hand, competitors enter the market with aggressive prices. It is forecasted that in 2050, innovative products and services demanded by the market will be based on state of the art design, manufacturing and certification processes with a significant reduction of the environmental impact. Recent studies have shown that the development and deployment of new structural technologies will have the greatest impact in the reduction of weight and operational costs compared to other technologies. Against this background, composite materials technology is of fundamental importance to current and future aircraft structures where high specific properties and integration of multiple functionalities are essential to improve weight, fuel efficiency, reduce CO2 emissions, and certification costs. The vulnerability of composite structures to localised, dynamic, sudden, and unexpected loads, may result in unpredictable complex localized damage and a loss of post-impact residual strength. The aim of the EXTREME project is to develop novel material characterisation methods and in-situ measurement techniques, material models and simulation methods for the design and manufacture aerospace composite structures under EXTREME dynamic loadings leading to a significant reduction of weight, design and certification cost.


Patent
AgustaWestland Ltd | Date: 2014-03-26

A gearbox including a housing, an input member rotatably supported in the housing, a rotatable shaft supported in the housing, gearing providing a power transmitting connection between the input member and the rotatable shaft; and an oil feed member held against rotation relative to the housing, wherein the oil feed member has at least one helical formation for causing oil within the gearbox to be fed axially of the oil feed member, on rotation of the rotatable shaft.


Patent
AGUSTAWESTLAND Ltd | Date: 2012-02-16

A helicopter tail rotor gearbox including a housing, an output shaft for connection to a tail rotor rotatably supported in the housing and having an open end therein, an input member rotatably supported in the housing, gearing providing a power transmitting connection between the input member and output shaft, a pitch control shaft for effecting a change in the pitch of the tail rotor, the pitch control shaft being disposed at least partially within the output shaft, rotatable therewith, and movable relative thereto along the rotational axis of the output shaft, an actuating member for effecting axial movement of the pitch control shaft, the actuating member being movable axially of the output shaft but held against rotation therewith, and a bearing assembly positioned in between the pitch control shaft and the actuating member for permitting relative rotation therebetween, wherein the gearbox includes at least one formation for diverting oil, dispersed within the housing in use, towards the open end of the output shaft.


Patent
AGUSTAWESTLAND Ltd | Date: 2014-02-25

A device for holding a bearing member relative to a fixed body, including a first part having a formation for engagement with a corresponding formation on a fixed body to hold the first part relative to the fixed body, and a receiving formation for receiving and slidably supporting a generally elongate second part, wherein a first end of the second part is configured for engagement with a part of a bearing member to hold the bearing member relative to the fixed body, and wherein a second, opposite, end of the second part supports an abutment member which prevents the first and second parts separating from each other, wherein the device includes biasing means for biasing the first end of the second part away from the first part.


Patent
AgustaWestland Ltd | Date: 2013-08-16

A gearbox including a housing; an input member rotatably supported in the housing; a rotatable shaft supported in the housing; gearing providing a power transmitting connection between the input member and the rotatable shaft; and an oil feed member held against rotation relative to the housing; wherein the oil feed member has at least one helical formation for causing oil within the gearbox to be fed axially of the oil feed member, on rotation of the rotatable shaft.

AgustaWestland is continuing research into helicopter active rotor technology; this will provide a step change in passenger ride comfort. With support from the Aerospace Growth Partnership (AGP), the Aerospace Technology Institute (ATI) and the Technology Strategy Board, AgustaWestland in Yeovil will carry out manufacture and test activities on an experimental active rotor system in preparation for flight test in 2014. The novel nature of the demonstrator system will require innovative new testing techniques to ensure the rotor can be flown safely. AgustaWestland will be supported extensively by the UK academic community and the aerospace supply chain.
