The Nuclear Thermal Turbo Rocket - A Conceptual High-Performance Earth-to-Orbit Propulsion System

Abstract: A new propulsion concept called the Nuclear Thermal Turbo Rocket (NTTR) is proposed for Earth to Orbit applications. The NTTR utilizes a nuclear fission reactor to thermally heat hydrogen propellant into a rocket plenum. The rocket nozzles are located at the tips of a variable pitch thrust fan connected to the plenum by passages in the fan blades, and each nozzle is a linear aerospike on the trailing edge of the blade.The thrust fan is located in a duct such that the heated hydrogen propellant is combusted wit… Show more

“…At low Mach numbers, sufficient thrust will be produced in this NTTR. [9] Seung Hyung Nam(et.al, 2015) said nuclear propulsion is one of the best ways to conquer the hard environment of space. Due to its high thrust and efficiency, NTR is a choice for space missions to Mars.…”
