This is an injector, with a spark plug, for a liquid fuel rocket of U.S. rocket pioneer Robert H. Goddard of ca. 1920s-1930s. It has a removable injector plate, slotted to accomodate a screw driver. It therefore may have been used to test injectors in static tests conducted by Goddard. The attached spark plug is for ignition.
It was found in the Smithsonian collections, but likely was originally part of a major gift of Goddard artifacts to the Smithsonian by the Daniel and Florence Guggenheim Foundation in 1950.
