Flame Deflector
</dt>
1. In a vertical launch, any of
variously designed obstructions that intercept the hot gases of the rocket
engine so as to deflect them away from the ground or from a structure.

''The flame deflector may be a relatively small device fixed to the top
surface of the pad surrounded by the framework of the launcher, or it may be a
heavily constructed piece of metal mounted as a side and bottom of a flame
bucket. In the latter case, the deflector may be perforated with numerous
holes connected with a source of water, bending at an angle of about 45� into
the line of the exhaust stream. During thrust buildup and the beginning of the
launch, a deluge of water pours from the holes in such a deflector to keep it
from melting. See deluge
collection pond.

2. In a captive test, an elbow in the exhaust conduit or flame
bucket that deflects the flame into the open.
