Thermally Efficient Fuel Management Technology

ABSTRACT: Turnkey Design Services of Blue Island IL proposes to develop and demonstrate that a gearbox driven, positive displacement variable delivery fuel system pump can be produced that will reduce thermal output by 35% and be comparable in weight/size to baseline aerospace centrifugal fuel pumps. The advantages of this new technology over baseline aerospace pumps include: Capability of rotating 2X faster than baseline positive displacement pumps which results in lower size and weight Capability to vary stroke and speed which leads to flow on demand and improved thermal efficiency Capability to predict remaining life and compensate for pump internal wear BENEFIT: The benefits of implementing the variable delivery pump include: Lower pump temperature rise Accurately provide flow on demand Lower engine system weight Health monitoring and fault detection capabilities Potential applications include the P & W1100G geared turbofan and the CFM International Leap-X series turbofan engines.
