The CM-LAS and the Birdcage

Posted on by .

Ares I-X hardware has the best nicknames.

These images show the Stack-5 Ground Support Equipment Lifting Fixture or as it is known to the I-X team, the “birdcage” being lowered over the Crew Module/Launch Abort System (CM/LAS) for a fit check. The birdcage is a metal framework that was collaboratively built and designed at the Langley Research Center in Langley, Virginia and Kennedy Space Center in Florida. It fits over the CM/LAS in order for it to be moved and stacked creating super stack 5.

The “birdcage” is bolted to the bottom of the crew module portion of the CM/LAS and then lifted into place (by one of the 325 ton overhead cranes in the VAB) and placed on top of the service module, which is already stacked on top of the Ares I-X rocket.  Technicians can then remove the bolts — from inside the CM — and the “birdcage” is removed.
