A TR-201 rocket engine, measuring approximately 48? tall with a nozzle diameter of 34?, marked on the top, "X108213-3 B, Manifold Assy, S/N XX4" and "XIII258-I, Man. Assy., Inj, S/N XXI." Also marked "004" on the opposite side. This type of engine was used as the sustainer for the second stage of the Delta II launch vehicle, incorporating a pintle injector designed by TRW and adopted from technology developed for the Lunar Module Descent Engine. In fine condition.

The TR-201 is a hypergolic pressure-fed rocket engine which uses Aerozine 50 as fuel and N2O4 as oxidizer. TRW developed it in the early 1970s as a derivative of the Lunar Module Descent Engine, using the same thrust chamber and incorporating the pintle injector. This injector technology and design is also used on SpaceX Merlin engines today. The TR-201 engine was used as the second stage for 77 Delta launches between 1972 and 1988, and the engine had a 100% reliability record during this 15 year operational period. A decidedly impressive piece of space hardware.
