Near the end of the NASA video Rocket Engine Testing the NASA Way! there is an image that appears to be archival an possibly quite old. It's a metal model of a launch vehicle with two very long boosters, probably for testing in a supersonic wind tunnel.

Can anyone recognize this object, what the purpose is or what experiment is being done, and say a little more about how it was used?

That is a model of the SLS.

ASA engineers and contractors tested four different payload configurations during the liftoff transition testing of a 67.5-inch model of the SLS at NASA Langley Research Center’s 14-by-22-foot subsonic wind tunnel in Hampton, Va.

  • $\begingroup$ Ah, I thought there were four side boosters grouped as two pairs because it looks like four nozzles, but looking at the image in your link, there are two, and each has a double-nozzle-like appearance. $\endgroup$
