Additively Manufactured Dynamically Adjustable Venturi, Phase I

Parabilis Space Technologies is pleased to propose development of a novel additive manufacturing based design which enables creation of a dynamically-adjustable, in-line, cavitating flow-control and measurement venturi  for use in advanced propulsion system ground testing. This innovative capability dramatically adds to and extends the advantages of using a cavitating venturi to isolate combustion chambers or other downstream process fluctuations from upstream feed pressure conditions. This design is expected to greatly simplify propulsion testing and reduce costs for cases where desired liquid flow conditions are either not precisely understood or cover a range of high-precision flow rates.  The proposed geometry is capable of scaling to both ultra-high pressure and high flow rate applications.
