Make flanges for the warm section rectangular?

NIC-FPS Response:

The current design for round flanges and V-groves on the cart has many
advantages for testing and maintenance of the dewar.  Our experience
with this configuration on rocket payloads (typically 1.5-2?  diameter,
12 ? long?twice the size of this instrument) indicate the V-grove
approach is stable and easy to live with.

Current plans are to have V-grove holders at each end of the front
assembly, about an inch or so inside of the flanges, with a restraint
strap between them. A third, retractable V-grove holder would be
positioned at the far end of the cart to support the removable shell
section when installed.  The end bell would be completely cantilevered
off the end of the cart for ease of removal. I believe that this
approach will provide a simple and extremely reliable method of
supporting the instrument during both operating and maintenance
cycles.
