Abstract
Disclosed are a nanoenergetic material composite-based solid propellant, a method of preparing the same, and a projectile using the same. The propellant includes: potassium nitrate-sucrose (KNSU) composite powder; and nanoenergetic material (nEM) composite powder in a solid powder form mixed with the KNSU composite powder to prepare a KNSU/nEM propellant. The method includes: preparing KNSU composite powder; preparing nEM composite powder; and preparing a KNSU/nEM propellant by mixing the KNSU composite powder and the nEM composite powder in a solid powder form. The projectile includes: a clay block; a clay nozzle 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. Upon ignition of the KNSU/nEM propellant, the nEM composite powder increases the combustion rate and combustion temperature of a potassium nitrate-sucrose (KNSU) propellant.
