Early design of the Apollo Lunar Module Ascent Engine Injector Plate, measuring approximately 13 x 13.5 x 4.75, engraved on the edge with part numbers, "8258-473040-1, #S/N1 C1." The outlet nozzles on top are etched, "Ox" and "Fuel." In fine condition. This was an essential component of the engine utilized by the Lunar Module to lift off from the moon and return its crew and precious cargo to a safe rendezvous with the Command Module for their return home. The injector proportioned the correct amount of propellant in just the right geometric configuration to provide combustion in the Ascent Engine’s thrust chamber. Development of the injector proved to be a significant challenge to Bell Aerospace and North American Rocketdyne who jointly designed and fabricated the Ascent Engine.
