Sonobuoy cartridge percussion apparatus

A sonobuoy cartridge percussion apparatus comprising:

• a CO2 cartridge filled with CO2 gas;
• a percussion ram configured to hit one end of the CO2 cartridge;
• a spring configured to enable the percussion ram to hit the CO2 cartridge by applying force to the percussion ram;
• a CO2 cartridge fastening body configured such that a spring reception hole is formed therein to enable the spring to be compressed and inserted into the spring reception hole;
• and
• a thread-shaped fastening member configured such that one end thereof is wound around the percussion ram and a remaining end thereof is passed through the spring reception hole, wherein the fastening member compresses the spring, and is fastened to a stop protrusion formed on the CO2 cartridge fastening body;
• wherein when the fastening member is broken by a heating resistor that generates heat, the percussion ram receives elastic force of the spring, and thus hits one end of the CO2 cartridge so that the CO2 gas inside the CO2 cartridge is discharged.
