Title:
PULSE TYPE PROPELLING MACHINE UNIT
Document Type and Number:
Japanese Patent JP2013174204
Kind Code:
A
Abstract:
To provide a pulse type propelling machine unit capable of operating while maintaining a high propelling efficiency for a long period of time.
A pulse type propelling machine unit has an electric discharge chamber formed from an upstream electrode, a downstream electrode, and a high melting point insulation member, and a supply part to supply a propelling agent to inside the discharge chamber. According to the constitution, the discharge chamber wall is not formed from a solid propelling agent itself, so that the discharge chamber remains out of deformation even though the solid propelling agent has worn ununiformly, and a high propelling efficiency can be kept.
