Unul din membri grupului nostru de aici lucreaza ptr Aerojet si ei tocmai au facut un test static cu motorul turnului de salvare pentru Orion.
Merita vazut, asta ca apropo de standuri. Cum se vede, chiar la case mai mari se pot intampla tot felul de lucruri, nu merg toate ca pe roate. Oricum testul a fost un succes.
Va dau un link de pe YouTube cu video.
Va pun textul in original, care intelege bine, care nu, doar se uita la poza si film.
“I designed the test stand. The motor put out almost 50,000 lbs of thrust
with a side vector created by making one of the 4 nozzle throats smaller.
The test stand was designed for 100,000 lbs of axial thrust and overturning
moment capacity of 216,000 in-lbs ( that is 9000 lbs acting horizontal at 24
inches above the stand to turn over the test stand). It also has a roll
capacity of 60,000 in-lbf or 4500 ft-lbs).
The test stand was supposed to have one multi axis load cell that measured all the moments, roll, and axial thrust. But the vendor making the load cell ran into some techincal and structural issues and was unable to deliver the loadcell in time for the test. That is why there is a gap between the "thrust collector" and the deck. That is where the multi axis load cell was supposed to be. I had to
rig up an alternate configuration with 7 different load cells to be able to capture all that was going on (this is our normal set up for horizontal tests). The new Jetison Motor test stand was to depart from old school and test vertically using just one load cell that could measure all direcitons
of loads.
We are hoping to get the multi-axis load cell in time for the next test.
Anyway, It was exciting to watch the test. It was surprisingly loud even in
the bunker/control room where I was and all the clapping came from. Enjoy!
