History
Ventions was founded in 2005 as a technology development and services company. Initial work focused on demonstrating use of a novel fabrication technique to realize fine featured injectors and cooling channels in rocket engines no more than a few centimeters in size. This was followed by use of the same technique for manufacture of small impellers with blade heights as small as 0.020 inches, and demonstration of small-scale turbomachinery-based pumps for on-board pressurization of propellants.
Ventions is currently integrating its propulsion systems, avionics and other pressurization / plumbing components into a full-up launch vehicle under a DARPA funded program.
Locations
Ventions primary office and lab is located in South of Market, San Francisco.
It also has a small presence in Washington DC, and a dedicated test-site for hot-fire testing of rocket engines and launch vehicle stages at Castle Airport in Atwater, California.
