1965 - Fuel-efficient rocket thruster that keeps today’s satellites in orbit

* Brill developed the concept for a new rocket engine, inventing the Electrothermal Hydrazine Thruster (EHT/Resistojet) for which she holds US Patent No. 3,807,657. * Her innovation resulted in not only higher engine performance, but also increased the reliability of the propulsion system. * She also proposed the use of a single propellant because of the value and simplicity that it would provide. * The reduction in propellant weight requirements enabled either increased payload capability or extended mission life. * Her invention became a standard in the industry and has translated into millions of dollars of increased revenue for commercial communications satellite owners.
