Smoke, colored rockets

Titanium (Ti) is used as a major component of Ti alloys, which are used as heat-resistant Ught metals for the construction of aircraft and rockets. Though Ti is also used as an anti-acid metal, it bums in air when heated above 1500 K. TiCl4 is a Uquid used to form colored smoke in air.

Smoke shells and rockets are used to produce smoke clouds for military signaling and, in daylight fireworks, for ornamental effects. The shell case or rocket head is filled with a fine powder of the desired color, which powdered material need not necessarily be one which will tolerate heat, and this is dispersed in the form of a colored cloud by the explosion of a small bag of gunpowder placed as near to its center as may be. Artificial vermilion (red), ultramarine (blue), Paris green, chrome yellow, chalk, and ivory black are among the materials which have been used, but almost any material which has a bright color when powdered and which does not cake together may be employed. 

Uses To produce yellow-colored smoke for military signaling from shells, rockets, or pots. In mixture with indigo for producing green-colored smoke. 

The primary source of perchlorate is the ammonium salt. Ammonium perchlorate is the oxidizer ingredient in solid propellant mixtures for rockets, missiles, and munitions. Other uses of perchlorate salts include medicine, matches, metal cation chemistry, and pyrotechnics (illuminating and signaling flares, colored and white smoke generators, tracers, incendiary delays, fuses, photo-flash compounds, and...

Launch sequence films from previous missions were examined in detail to determine if there were any prior indications of smoke of the color and composition that appeared during the first few seconds of the 51-L mission. None were found. Other vapors in this area were determined to be melting frost from the bottom of the external tank or steam from the rocket exhaust in the pad s sound suppression water trays.
