Military Technology

The invention is an aerosol search and rescue (SAR) grenade. A smoke signal is produced that is comparable to the smoke signal produced by a pyrotechnic grenade. An aspirating provides a propellant gas/air mixture to a reservoir of smoke material. A container configuration and gravity operated valve provide for a smoke plume only in the upward direction. The smoke grenade is useful in life rafts. It is also useful in inland areas posing a risk of fire.
