Development of N-class potassium nitrate - sorbitol solid propellant rocket motor / Mohamad Amirul Muhammad

In the age of Internet of Things (IoT), satellite launching has become more common than for the past decades. To date, rocket system is the only means of bringing satellites into Earth’s orbit. However, the technology is very localized, and Malaysia is still in an embryonic stage. In this thesis, th...
