News & Events-Frazer-Nash set to deliver future architecture project in support of MOD research programme


Engineering consultancy Frazer-Nash is set to deliver a project looking at the electrical architecture of the future for MOD in support of the Advanced Electric Power and Propulsion Project (AEP3) being run in conjunction with the US Navy until 2017.

The consultancy will look at the future of naval vessels by developing a set of models that analyse the optimum way to design and power the marine vessel of the future. The work is based on existing modelling tools delivered to MOD under the Maritime Equipment Systems (MES) Enabler. This framework was awarded by the Equipment Support Group (ESG) under competitive tender in 2011 and offers the provision of mathematical modelling and technical support for marine power and distribution systems.

Frazer-Nash is developing the models using virtual blocks that represent the core parts of a ship's electrical system using SimPowerSystems within the MATLAB/Simulink toolset. These models will then be validated against hardware in the loop test data at a later stage of the AEP3 programme of work. The approach has adopted a Model Based Systems Engineering (MBSE) methodology to verifying and validating modelling requirements in SysML. By adopting this strategy, it will be possible to demonstrate full traceability from requirements to implementation and validation.

This work will help to characterize, model and de-risk electrical power and propulsion system architectures and technologies for future surface platforms to meet the needs of both Navies. The project could increase propulsion power density and efficiency, develop advanced distribution systems, reduce Life Cycle Cost, make scaling integrated power systems affordable in smaller vessels, and accommodate increases in electricity demand from equipment that requires greater amounts of energy, including sensors and weapons.

Commenting on the work that Frazer-Nash has done to date, Chris G Jones at Frazer-Nash said: "We are very pleased to be working on such an exciting and challenging project for the MOD which builds on the work that we have been delivering for the last three years through the MES Enabler agreement we hold with MOD. Having the chance to model concept architectures for our future naval vessels is a unique opportunity and one that plays to our extensive expertise in systems engineering and naval power systems."

This appointment follows Frazer-Nash's selection onto the framework as the preferred supplier by the Equipment Support Group (ESG) under competitive tender in 2011.
