No, the overheating issue is still valid. Currently TMS (thermal management system) is still a bit dodgy. Since the PAO(liquid coolant for avionics) lines still run through the fuel tanks, and the addition of heat from being in the sun, the F-1B temp still gets rather high. There are ways around this however. One is chilled fuel. Chilled fuel is not easy to come by, so there are two more practical measures that are usually pursued. Sun shelters help quite a bit to keep temps down. The other one, well, just get out of chocks before F-1B reaches 160*.


calhoun, it is a good read on your account to the overheating issue. Sounds privileged, but I'm sure you know best.

I'm just wondering, why are these problems not identified and resolved when the Raptor was tested in ED?


regards,


These problems were identified during OT at Edwards. It was one of the main concerns from both ops and maintenance. There have been improvements, ie tweaking some of the software for the IVSCs to adjust valve positions and timings for what goes where. Its not as bad as it used to be, but it could be a lot better.
