Abstract:

A survey was conducted of essentially nongaseous flare systems at sea level and reduced pressure conditions equivalent to altitudes ranging up to l00,000 feet. The luminosity of nongaseous systems was found to undergo less reduction and their pressure coefficient of burning rate showed less change on transition from sea level to reduced pressure conditions that those developed by gaseous flare systems. It was found that nongaseous systems, when tested at reduced pressure, gave candlepower and burning time values that approximate or exceed those of standard magnesium-sodium nitrate compositions under the same reduced pressure conditions. No nongaseous system studied produced greater candlepower or luminous effieiency at reduced pressures than the metallic calcium gaseous systems found optimum for low pressure use. The materials investigated were Zr, CaB6, B, and mg as fuels and Mn02 B203, Mo03, Cr203, W03, Bi203, BaCr04, Ba02, Sr02, Fe203 as oxidants. Author
