Abstract
A safe and arm device with a thermomagnetic generator sharing a tubular sed shaft with a turbine. Weapon propellant exhaust gas enters the shaft and heats thermomagnets in the generator causing their magnetism to be produced and flux lines to flow from rotor to stator. The gas moves translationally through the shaft and into the turbine. The gas leaving the turbine rotationally is discharged into a radial exhaust tube. A plug in the tube must be removed to permit gas exhaust from the turbine. Only then can the turbine and connected generator rotate causing the thermomagnetically produced flux lines of the rotor to be cut by the stator resulting in an induced voltage out of the generator.
