Filton Systems Engineering (FSE) intends to establish methodologies, which have been verified using test data, to provide validated accurate surge pressure predictions within aircraft fuel systems. This would replace physical Aerospace Test Rigs with a virtual test rig to reduce development cost and lead-time by improving the robustness/integrity of surge/ two phase flow fluid modelling. This allows aerospace companies to optimise architecture early in the design phase minimising installation and structural weight, increasing aircraft efficiency, thereby lowering operating cost and also reducing carbon footprint.Commercial realisation of the programme is through the sale of services/methodologies to aerospace customers and also potentially through the sale of validation test data to software houses to improve their marketing position relative to claims for predicting surge pressures; and the expansion of methodologies to cover fluid applications in other industries.FSE is uniquely positioned to succeed within this task due to existing surge analysis, test management and rig specification capabilities which will also protect further work that develop from this programme of work.The feasibility study undertaken under Phase 1 will comprise:1. IP investigationa. Current IP for similar methodologiesb. Use of IP to protect methodologiesc. Use of copyright to protect data2. Potential commercial arrangements with final customersa. Requirementsb. Use of data, services & methodologies 3. Potential commercial arrangements with software housea. Support for commercial codeb. Use of validation test data4. Statement of Work for Phase 2 (inc. plan & budget)5. Top level test facility requirements6. Top level test requirements7. Produce Comprehensive Feasibility ReportIf Phase 1 is successful, further funding will be applied for under Horizon 2020 Phase 2 with FSE providing the balance of the funding. It is estimated that Phase 2 will take a further 2½ years.
