Title: Fueling mechanism for Ares
Post by: anasri1987 on 08/14/2008 04:05 pm
i am starting this thread to get information on the fueling mechanism used for the Ares.

thanks

Why?   It is the same as the shuttle's.  No big changes will be needed

can i have the details of the fueling mechanism used as in some kind of detailed drawing or in dept explanation would be of help.

thanks

Ares I

Current plans are to fuel the crew module's hyergol  (monomethel hydrazine and nitrogen tetroxide) reaction control system prior to integration at the VAB. Similar to other un-manned payloads.

The second stage Reaction Control (for roll mitigation) will be fueled with hypergols prior to intergration at the VAB, The second stage empty will be hoisted in to place.

Both hypergol loading opperation will be using a tanker dirrect propellant transfer system using tanker trucks similar to the Delta 2 second stage or other payload opperations.

A mid crallerway loading station for hypergols was proposed at one time.

Second stage loading will be via modified pad LOX and hydrogen lines to the ML then piped to the FUT umbilical connection near the base of the second stage

Ares V

Most likely fueled at the Pad like shuttle since it appears to be a LOX and hydrogen.

You'd be wise to get L2. It's got literally everything on Ares.

The second stage will be likely fueled with hypergols prior to intergration at the VAB, transporting a full second stage and hoisting it in to place.


The Ares I upperstage uses LH2 and LO2.  Its RCS/ACS systems                      will likely be self contained units that can be fueled offsite and then be installed at the VAB.  Much like the S-IVB ACS

Agreed I ment the second stage RCS ring hypergol load would be loaded off site and stacked fully loaded in the VAB. Emergency de-tanking is a work in progress.

For Ares I the first stage is solid
second stage LOx/LH2 (same as shuttle ET fuel)
