3-D simulation of liquid rocket fuel mixing in the ejection head of a liquid rocket fuel system using CADRA III software. Prior to implementing the final design, StellaCAD Corporation (formerly Russo International) optimized

the angles of the jets of fuel along with the flow rates and control.

Major component of anassembly to a special excavating ISRU device similar to the bucket wheel ladder. The solid model was created using Inventor software. The design was created in 2005 and consists of dust suppression and self-cleaning methods.

3-D Solid Model of StellaCAD's excavating/mining cutting tool attached to a rotating shaft. This is part of the In-Situ Resource Utilization (ISRU) unit that was created by Joe Russo in the mid-90s; it was proposed for use in excavations on the moon and other bodies in space.  Our concepts were well received by the science community.  The model was constructed using Solid Works software.
