A bird launcher for hunt training with a door through which a bird is placed in a guide belt in an interior of a housing substantially eliminates injury to the bird. An elastic spring mounted at one end of an operating rod substantially eliminates inadvertent movement of an operating rod thereby preventing a premature launch, thus improving the safety of the operator and the bird. A fixing member is centered on the bird launcher's longitudinal center line and extends to at least one-half of a length of guide rods. The fixing member places pressure in the approximate center of the guide rods thereby preventing the guide rods from opening at the ends and additionally creating a balanced release point when the bird launcher is activated. The balance release point ensures a more stabilized launch so that the bird is released in a desired direction.

A cold-launch uses shape-memory-alloy (“SMA”) actuators to accelerate materiel to a required launch velocity. The SMA actuators are arranged into one or more actuation stages. SMA actuators within a given actuation stage are simultaneously triggered. Actuation stages, however, are triggered sequentially, each triggering adding to the velocity of the materiel.
