Carbon nanotubes (CNTs) are cylindrical molecules with unique structural and electronic properties, making them promising candidates for enhancing the performance of nuclear thermal propulsion (NTP) systems. NTP involves using nuclear fission to heat a propellant, typically liquid hydrogen, to high temperatures before expelling it through a nozzle to generate thrust. The specific thrust equation for rocket propulsion is given by F=m˙ve​+(pe​−pa​)Ae​, where F is thrust, m˙ is mass flow rate, ve​ is effective exhaust velocity, pe​ is exit pressure, pa​ is ambient pressure, and Ae​ is exit area.
