Propeller with Adjustable Thrust for Reducing Operational Losses "PATROL" is a project led by Teignbridge Propellers International in partnership with; University of Warwick manufacturing group (WMG) and iNetic.
This pre-deployment trial-based feasibility study will develop a cutting-edge, fully electric azimuthing podded drive with an automated control system to adjust the thrust loading on the propeller blade to improve propulsion efficiency and reduce emissions from marine vessels.
Our project aims to create a novel and impactful electric propulsion system utilising an azimuth pod design with a highly efficient propeller system featuring adjustable control surfaces. This initiative will integrate a compact electric motor and transmission propulsion driveline with advanced inverters and a DC power system, coupled with the azimuth pod, to develop an effective, efficient, and versatile drive suitable for medium power applications like workboats. The innovation of merging this new propeller with an electric drive results in total energy consumption improvements that surpass the individual efficiency gains of each component. These advancements are expected to significantly reduce emissions using battery electrical storage and decrease the amount of material (battery, mass, and power) needed by enhancing energy utilisation and efficiency.
In order for the International Maritime Organisation and the UK government to meet their targets of 50% reduction in carbon emissions by 2050 (compared to 2008 levels), technologies such as PATROL must be developed in order to reduce carbon emitted by hydrocarbon burning vessels which currently dominate marine transportation.
In addition, PATROL project's on-board data gathering and control system supports the UK Government's and the Department for Transport (DfT) plans for developing smart shipping in the maritime sector. This project could strengthen and enhance the UK's reputation as a leading maritime country in the field of electric propulsion and autonomous vessels.
Marine propulsion is a multi-billion pound industry undergoing a rapid change from direct drive diesel and petrol to electric. To support this change there is an urgent need for innovative electric propulsion systems like those being developed by RAD. The technology that RAD has developed is safer (no external rotating blades), more robust to becoming entangled with debris and has minimal moving parts. Reducing product and manufacturing complexity and costs are critical if such a product is to fill this current gap in the marine UK PEMD market.
This is a collaborative project between RAD Propulsion Ltd, iNetic Ltd and the National Composite Centre. The team will undertake industrial research targeted at significantly reducing Bill Of Material (BOM) costs, improving manufacturability and enabling early life product monitoring of the PEMD element of the marine rim-drive hubless propulsion system that RAD has developed.
This project is focused on the manufacturing element of our products PEMD technology and so directly underpins the UKs move towards electrification and is a key step in Driving the Electric Revolution
Electric rim drives and hub-less propellers are not new technologies but the merging of the two together into a single product to achieve the levels of performance needed in the target market means its introduction will be transformative to the marine market in the sub 50kW power range.
The operating environment, the required manufacturing tolerances and the performance demands placed on the product in this market introduces specific technological /manufacturing process challenges that this project will address, namely:
* the hydrodynamic drag effects from the motor housing are critical if the required boat speed is to be achieved.
* the rim drive and the materials its manufactured from must withstand submergence in salt water for prolonged periods
Our product not only opens the way to a huge new market sector but is a stepping stone towards the introduction of green technologies into a sector that is traditionally dominated by fossil fuel engines. There is clear commercial opportunity and conservative analysis indicates that the current global electric propulsion market in this size range is ~£150-200m/year with strong indications of growing to £1.5Bn+/year over the next decade.
We have assembled a strong and experienced project team consisting of RAD Propulsion Ltd (Lead Partner), iNetic Ltd (motor supplier) and are supported by the National Composite Centre (NCC) who will provide specialist materials and manufacturing expertise in the use of composite materials.
Jaguar Land Rover demands the development of cutting edge electrified propulsion technologies to remain globally competitive. This aligns to and sustains the strategy for all new Jaguar Land Rover models to have an electrified option from 2020.
Jaguar Land Rover have created a consortium of world class academic and industrial partners to create a state of the art electric drive unit (EDU), and the supply chain to deliver it, to power future Jaguar Land Rover electric vehicles.
The electric drive unit will stretch the boundaries of the electric motor, inverter and transmission technologies to provide an integrated electric drive unit which will offer class leading efficiency for increased vehicle range, coupled with high power and torque density, all within a lightweight and compact package envelope.
The unit will build on Jaguar Land Rover's existing learning and partnership arrangements and will provide Jaguar Land Rover and its expert consortium partners with a competitive edge intended to create UK intellectual property (IP) and supply chain.
Jaguar Land Rover will provide overall management of the programme, and lead specifically in the areas of integration and industrial procurement.
The expert UK based partner group will lead in the following areas:
Industrial partners
MDL, Inetic, Lyra will lead on e-machine and inverter design, analysis,integration and support prototype build.
Tata Steel and Bradauer will lead on electric steel material supply and stamping development.
Fuchs will lead on lubricants/coolants and support design, analysis and manufacturing.
Academic partners
WMG will support EDU and e-machine integration, manufacturing and metrology,analysis, pilot build and testing.
Newcastle University will support transmission design, including prototype build and testing.
The proposed industrialisation of the unit at Jaguar Land Rover's Engine Manufacturing Centre (EMC, Wolverhampton, UK) will serve to create and sustain UK job opportunities within Jaguar Land Rover; the project's industrial and academic partners; and critically, it will provide a compelling product landscape to drive additional vehicle sales and promote the establishment of a UK production supply chain. The involvement of UK subcontractors and SMEs will represent a key enabler to the development of a UK production supply chain.
The creation of this EDU is intended to cement Jaguar Land Rover's position as a provider of world class electric vehicles, evidenced through the recent Jaguar I-PACE triple award of "2019 World car of the year"; "World car design of the year, and "World car green award".
Williams Hybrid Power (WHP), supported by GKN Land Systems, have developed a hybrid system to regenerate braking energy on city buses utilising their Gyrodrive system with a high speed flywheel originally developed for Le Mans Prototypes KERS technology.
To date this development work has shown the fuel savings in excess of 25% for the bus operators.
In this new project WHP and GKN have joined with Alexander Dennis Limited (ADL), the UK biggest bus manufacturer, to develop a solution that will be optimised for fitment to buses as original equipment at build. This will widen the potential market for the technology, generating genuine cost savings throughout the industry and giving opportunity for increased production and export success. In this project WHP will develop the Gyrodrive technology, GKN will use its manufacturing skills to develop the production systems and ADL will supply its expertise in the manufacture of buses and their knowledge of the customer base. GKN will also look to exploit the technology into its key customer markets such as off highway machines
