CygniSearch is developing a single-stage centrifugal turbopump system, equipped with the first split-ball, inverse blade impeller, designed to reduce erosion to the turbine and peripheral turbopump system components. Contained in a specially, designed compression housing, the SilverSun turbine has the potential to reduce rocket engine failure rates, optimize launch vehicle performance, and improve space program safety margins.
About one in twenty rocket launches fail every year costing insurers of space missions, launch vehicle operators and their customers billions of dollars. Blade fatigue due to the effects caused by cavitation in conventional, liquid propellant rocket engine turbopump systems, often trigger system failures thus having a negative impact on crew safety and payloads, forcing program launch priorities to shift thus increasing financial risk.
Rapid changes in pressure and temperature due to the high velocity of fluid circulating and being circulated by the turbopump’s internal components causes phase changes to occur in the liquid producing shockwaves that initiate implosion cycles that can damage or destroy space transportation systems.
CygniSearch has the intention of offering rocket launch vehicle manufacturers and operators a reliable and cost-effective fuel management solution with the SilverSun, a stable turbopump system that features an advanced impeller design. The SilverSun split-ball inverse blade impeller’s helical hemispheres, behave similarly to conventional turbine designs but is able to offer increased fuel flow stability for bipropellant feed systems and is more resistant to cavitation.
The inverse blade impeller turbine’s architecture consist of a sphere solid superstructure, a reinforcing sphere solid substructure, and a series of spherical wedges that radiate from the base circumference to the polar region of the impeller, resembling vacuous spiral arms. The wedges are deep contours that are angled and shaped to control vorticity and to stabilize the molecular structure of liquid, thus reducing the effects brought on by cavitation. The primary and secondary spheres act in concert to provide added structural integrity and to leverage angular momentum. The dual sphere structure also serves as a heat sink, helping to stabilize temperatures inside the turbopump system during the time of operation.
The SilverSun turbopump is a versatile technology platform and can easily be customized to handle differing bipropellant rocket motor customer system requirements as well as be reconfigured to accommodate monopropellant fuel feed systems. Likewise the durability of our turbopump makes it a good fit for customers that are in the process of developing and using reusable launch systems.
The Silversun turbopump system was initially designed to be manufactured in small batches using CNC lathes. However, early prototypes are being produced using 3D printers and our research suggests that our turbine assembly would be a great candidate for additive manufacturing
The Silversun is a world-class fuel feed solution that shows great potential for providing safer passage to space by reducing the number of launch-related accidents, saving launch systems manufactures and their customers billions of dollars in unforeseen annual costs, as well as having the potentially reshape the turbomachinery industry.

David is inspired by:
My general sense of complex systems in nature has been the driving impetus for my portfolio of design concepts, routes toward scientific inquiry and the desire to explore the unknown as well as to conceive beyond what is commonly accepted as fact. The philosophical center of my engineering and problem solving strategy combines the formulations for Chaos Theory, The General Theory of Relativity, Evolution and Natural Selection. Together these concepts serve as a guideline for analysis and a solid foundation for hypothesis. It is through this lens that I have been able to imagine other Earth-like worlds, parallel universes and differing configurations of our universe or multiverse. It is this same imagination that has allowed me to embrace uncertainty, and to tackle difficult engineering problems.
