Your Reply: HTML is ON UBB Code is ON Smilies Legend	[QUOTE]Originally posted by SpaceAholic: [B]The below reply received from retired Rocketdyne Engineer Tim Harmon, an authoritative expert on ablatively cooled engines who developed the SE-7, SE-8 and Lunar Module Ascent Engine, responding to my inquiry regarding the probability that the engine is flown. SE-6 development/testing was concurrent with the SE-7/SE-8's. I think this is a good exercise, first to better understand the visible characteristics/signature of flown ablative engines as a number of SE-6's (and CM SE-8's) were de-installed from returned Gemini capsules for post flight analysis and may still be circulating in the public (all flown SE-7 variants were jettisoned with OAMS packages in space). It's also important to solicit an understanding of the type of testing Rocketdyne was capable of conducting (and its attendant limitations) from the folks who actually worked these programs prior to loosing them. <BLOCKQUOTE>[i]Your guess is probably correct...that is probably an engine that has flown and re entered. We did not have a way of simulating re entry at Rocketdyne.[/i]</BLOCKQUOTE>[/B][/QUOTE]
