“…Since 1960, the KNO3 with sugar as based fuel, was implemented for the first time in the fabrication of a low cost / low-performance propellant, showing low specific impulse compared to propellants with Ammonium Perchlorate (1). The implementation of this propellant and its derivatives (with sugar -SU, dextrose -DX, or sorbitol -SB) has been popular for the development of small and low cost Solid Rocket Motors Systems (SRMS) around the world, specifically in academic research, and also known as candy propellant, few successful projects were implemented in engineering departments of universities like TU Delft, see (3)(4)(5). The production of solid propellants allows the design and implementation of sounding rockets, essential for the development of aerospace technology.…”

“…In Brazil, the Rocket Design team from the Technology Aeronautical Institute (ITA), developed rocket motors with the KNO3/SO propellant, presenting practical methods for the manufacturing including the use of a casting machine (3,10) and the development of high-performance propellant (11). Other academic projects include the use of KNO3/SB in the second stage of a sounding rocket to recover a glider, work that was presented by Baran et al (12).…”

The use of the Potassium Nitrate as an oxidizer in solid rocket propellants has been common in recent years for experimental research in solid rocket propulsion systems. This chemical is used as a compound of black powder and explosives, but in the last 30 years, it has been studied for applications in semiprofessional rocket propellant, implemented by Universities in research and academic projects. The Potassium Nitrate/Dextrose propellant is also known as Candy propellant and presents some advantages compared with other solid propellants. They are low production costs and ease of acquisition for the chemical components. These advantages are attractive for low-cost projects, compared to the low performance; this does not discourage its use.The Candy propellant presented a lack of experimental data to characterize, for example, its thermal properties. For this reason, were used the Differential Scanning Calorimetry and the Semi-Micro Calorimetry tests, to obtain the heat of combustion, power, and temperatures of melting and ignition. The grains of Candy propellant were manufactured at the University of Conception by the Propulsion Interest Team. This is the first time which is reported the calorimetric data of the Candy propellant (Potassium Nitrate/Dextrose). The results in this work presented a heat combustion in the range 523 -567 Cal•g −1 , decomposition temperature in the range 356 -361 °C and a heat released in the range 1080 -1809 J•g −1 of the mixture KNO3/Dextrose, which contribute to the professional characterization of the propellant.

“…Finally, black powder facilitates insertion of rocket lessons into chemistry classes since combustion processes can be analyzed and tied to motor performance [41,42]. Intrepid chemistry teachers may even consider segueing from black powder to sugar as fuel and developing lessons where students study stoichiometry by mixing, shaping, and launching their own propellant/oxidizer combinations [43,44].…”
