The Bantam family goes all the way up to 200,000 pounds of thrust and can be adapted to different fuels such as kerosene, ethanol, methane and storable propellants. In addition to reducing the cost of the engine by about 65 percent, the team was able to reduce total design and manufacturing time to a couple of months, when it would usually take more than a year for this kind of engine.<\/p>\n<p>\u201cWe are not just making a stand-alone chamber or injector derived from traditional design approaches.
