Nanoenergetic material composite-based solid propellant, method of preparing the same, and projectile using the same

A method of preparing a nanoenergetic material composite-based solid propellant, comprising:

• preparing potassium nitrate-sucrose (KNSU) composite powder;
• preparing nanoenergetic material (nEM) composite powder;
• and
• preparing a KNSU/nEM propellant by mixing the potassium nitrate-sucrose (KNSU) composite powder and the nanoenergetic material (nEM) composite powder in a solid powder form,
• wherein upon ignition of the KNSU/nEM propellant, the nanoenergetic material (nEM) composite powder increases the combustion rate and combustion temperature of a potassium nitrate-sucrose (KNSU) propellant.

A projectile using a nanoenergetic material composite-based solid propellant, comprising:

• a clay block disposed at an upper portion thereof;
• a clay nozzle disposed at a lower portion thereof and responsible for releasing the pressure generated by explosion of a propellant;
• and
• a propellant lamination area disposed between the clay block and the clay nozzle,
• wherein a KNSU/nEM propellant prepared by mixing potassium nitrate-sucrose (KNSU) composite powder and nanoenergetic material (nEM) composite powder is laminated in the propellant lamination area, and
• upon ignition of the KNSU/nEM propellant, the nanoenergetic material (nEM) composite powder increases the combustion rate and combustion temperature of a potassium nitrate-sucrose (KNSU) propellant.
