Abstract
Aerial training flare or flare simulator comprising a polymeric case, a begradable polymeric candle housing, and a candle comprising a pyrotechnic illuminant and an environmentally friendly, fast-burning ignition composition. An expulsion cartridge ejects the candle and the candle housing while the case is retained on the launching aircraft. The only major component of the flare which falls to earth is the partially melted candle housing, which is biodegradable and thus reduces requirements for environmental cleanup.
