Turnkey Design Services, LLC — Department of Defense SBIR Phase I: Emerging platforms such as stealth aircraft have three to five times the heat load of lega

Description

Emerging platforms such as stealth aircraft have three to five times the heat load of legacy platforms while being limited in their ability to reject heat to the environment due to the reduction of vents, grills and inlets that create radar and infra-red hotspots. This increased heat load is the result of modern avionics, advanced mission systems; fueldraulic based vectored thrust control systems, increased use of composite structures, and larger more electric aircraft engine accessories such as generators, or environmental controls. To reduce overall fuel system temperature rise through main engine oil pumps, Turnkey Design Services of Blue Island, IL proposes to design a variable delivery, two stage fixed displacement pump for aerospace applications that has excellent metering capability due to the ability to vary stroke and speed, good thermal efficiency due to the ability to completely unload one stage.
