Abstract (en)
[origin: US6324982B1] The invention involves a process for artificially triggering an avalanche. The invention process includes a first step of filling at least one flexible envelope with an explosive fluid and a second step of triggering an explosion of the aforesaid fluid within each envelope, each envelope being destroyed by the explosion of the fluid. The destruction of the envelope allows for propagation of an aerial spherical overpressure wave which will affect an optimal area of the blanket of snow to be removed and will shake the aforesaid area and trigger an avalanche. The invention also involves a device for applying this process, the aforesaid device including at least one envelope to contain the explosive fluid, and means to trigger the explosion of this fluid within each envelope.
