Primordial helium from the beginning of the solar system may be stuck inside Earth's solid core, new research suggests. The findings could have implications for a long-standing debate about how ...
They found that this technique effectively tripled the thrust of solid-fuel rockets ... and the SM-3 Block IIA interceptor, rely on detecting hot rocket plumes. Helium could provide a means ...
detailed how injecting helium into traditional solid rocket motors via micron-scale pores triggers a thrust surge. Helium does not burn, but optimal ratios of helium to combustion gas (1:4 ...
