SpaceDev has been issued a United States patent for its hybrid propulsion technology. The U.S. Patent Office issued U.S. Patent No. 7,069,717, entitled “Hybrid Propulsion System,” to SpaceDev for technology related to fine altitude and control systems on a spacecraft. The patented Hybrid Propulsion System provides increased control of thruster minimum impulse over conventional systems while simultaneously reducing oxidizer waste. This translates to reduced costs and higher efficiency for SpaceDev’s systems. According to the patent, liquid oxidizer from a main motor is used in a gas thruster by converting the liquid oxidizer to a gas state. This ensures that gas, rather than liquid, is delivered to the thruster.
The technology behind the patent was developed and funded by SpaceDev. SpaceDev creates and sells affordable and innovative space products and solutions to government and commercial enterprises. SpaceDev’s innovations include the design, manufacture, marketing and operation of sophisticated micro- and nano-satellites, hybrid rocket-based orbital Maneuvering and orbital Transfer Vehicles as well as sub-orbital and orbital hybrid rocket-based propulsion systems for safe human space flight.
