Abstract: An avalanche triggering apparatus having a tower that is connected to a base and two detonation chambers. Two pairs of gas supply lines are configured to deliver fuel gas and an oxidizer to the two detonation chambers. Two spark plugs are configured to initiate combustion of gases within the detonation chambers when activated by one of two flow switches. One or more batteries are configured to provide electricity to the two spark plugs. The detonation chambers are connected to the tower via a central mounting assembly, two detonation mounting assemblies, and a plurality of isolator springs disposed between the central mounting assembly and each of the two detonation mounting assemblies. The central mounting assembly is comprised of a main gusset plate, two side plates, two rear plates, a top frame, and a bottom frame. Each detonation mounting assembly is comprised of a central plate and two side plates.

Abstract: An avalanche triggering apparatus having a tower, a detonation chamber, and gas supply lines that are configured to deliver fuel gas and oxidizer to the detonation chamber. The flow is gas is controlled remotely, and a spark plug is configured to ignite gases within the detonation chamber based on the flow of fuel gas through a flow switch that acts as a sensor. The detonation chamber has a closed, rounded top and an open bottom end that is configured to face a snow surface. The detonation chamber is connected to the tower via mounting brackets and two pairs of isolator springs. Each isolator spring is comprised of a helical cable isolator that is inserted through a plurality of holes in two aluminum members in a helical configuration. The tower is comprised of at least two sections that are secured together via flanges.
