$88000.00

A 1960's original all-titanium rocket engine combustion, throat and expansion shell; as thick as a dime. Three feet in diameter and 40'' tall. 23 lbs.
The engine chamber and exit bell portions were machined from 6A1-4V titanium alloy forgings and welded into one unit at the throat centerline. The shell thickness is a uniform 0.035" except at the upper end where the head end bolts on, and at the lower flange where the nozzle extension attaches. This is the design tested and flown in the Apollo Moon program from TRW in Euclid Ohio.
All these Lunar Module descent engines that were carried into space on the Saturn-V have remained there, a few others are on public display. This LMDE was aliquid chemical rocket engineconsisting of an ablative combustion chamber and nozzle throat held within a continuous titanium shell, covered with a lightweight insulated shield.... with a maximum thrust of 10,500 lbf. Of the 28 engines delivered to NASA,10 were tested at White Sands and9 flew.
This engine is a very late iteration, part number '109403-6' Revision-1, upgraded during manufacture by Ryan Aeronautical, San Diego.
This rocket engine is discolored from test firing, and the one inch flanges that held the nodal-point gimbal externally are missing.
This was the only throttleable design built for mannedUS moon exploration.
