MADISON, Wis. (Nov. 10, 2015) - Sierra Nevada Corporation’s (SNC) wholly-owned subsidiary Orbital Technologies Corporation (ORBITEC) recently completed successful testing and demonstration of three different propellant combinations for its existing 30,000-pound thrust vortex rocket engine. Completing this advancement in less than a year, ORBITEC is rapidly progressing its offering of engines for orbital maneuvering, upper-stage engines that ignite at high altitude, and small-to-medium-scale air and ground launch stage engines.
“We are extremely optimistic about the performance and broad application of the vortex engine which, during tests, exhibited very smooth and stable combustion and Specific Impulse efficiencies,” said Tom Crabb, ORBITEC’s executive vice president and chief operating officer. “With ORBITEC’s natural ability to rapidly iterate design and testing, these performance results should quickly lead to refinement and qualification of engines for next generation launch systems and to continued scaling for larger engines.”
These tests demonstrate the ability to transition use of different propellant combinations in the same core rocket engine design with slight changes to accommodate a specific combination of fuel and oxidizer, including propane and kerosene fuels with nitrous oxide (laughing gas) and liquid oxygen oxidizers. This latest development offers customers a suite of engines scalable to higher thrust levels and customer-selected fuel combinations from a single core rocket engine design. ORBITEC’s patented vortex rocket engines utilize a unique swirling propellant flow to naturally cool the engine walls, allowing for the development and manufacture of simpler, low-cost, light-weight and more robust rocket engine systems.
“SNC is very pleased that ORBITEC has exceeded expected performance and efficiency targets for this rocket engine,” said Mark N. Sirangelo, corporate vice president of SNC’s Space Systems. “ORBITEC is going to apply their patented vortex engine technology to develop a new family of rocket engines that will serve as booster and upper-stage engines for a variety of customers such as the U.S. Air Force, NASA and other commercial space companies.”
