Space Shuttle ice suppression system validation, volume 2
Abstract
The influence of nozzle size is dramatically illustrated in lab runs. It appears that increasing the size of the nozzle provides better coverage of ogive and mid-region of the external tank. It is interesting to note, however, that for the bottom region of the external tank, coverage seems to decrease with nozzle size. This can be explained if both the assymmetry of the lower set of nozzles and the blockage provided by the Orbiter aft-support structure are taken into account.
