Goddard's Patent Date: 07.07.1914 In 1914, rocketry pioneer Robert Goddard received two U.S. patents, one for a rocket that used liquid fuel, the other for a two- or three-stage rocket using solid fuel. At his own expense, he began to make systematic studies about propulsion provided by various types of gunpowder.
Goddard's designs influenced the basic system elements and functions found in all modern-day liquid rocket engines.
