Ventions

Ventions, LLC is a launch vehicle development company based out of San Francisco, California, that has been working to develop pump-fed, liquid bipropellant propulsion engines for DARPA and NASA.〔(【引用サイトリンク】url=http://aviationweek.com/awin/darpa-revisits-air-launch-focus-cost )〕 Most recently, Ventions was a technology provider for DARPA's Airborne Launch Assist Space Access program, and is currently working on the Small Air Launch Vehicle to Orbit (SALVO) program, a pathfinder air-launched vehicle for placement of cubesat sized payloads into Low Earth Orbit.
== 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.
