Assessment of McRm Boost Assist from Orbit for Deep Space Missions

By: Nasa, National Aeronautics and Space Adm

Report provides results of analysis for the beamed energy driven MHD Chemical Rocket Motor (MCRM) for application to boost from orbit to escape for deep space and interplanetary missions. Parametric analyses were performed in the mission to determine operating regime for which the MCRM provides significant propulsion performance enhancement. Analysis of the MHD accelerator was performed numerical computational methods to determine design and operational features necessary to achieve Isp on the order of 2,000 to 3,000 seconds. Algorithms were developed to scale weights for the accelerator and power supply. Significant improvement in propulsion system performance can be achieved with the beamed energy driven MCRM. The limiting factor on achievable vehicle acceleration is the specific power of the rectenna.Marshall Space Flight CenterDEEP SPACE; MAGNETOHYDRODYNAMICS; POWER BEAMING; ROCKET ENGINES; SPACE MISSIONS; ACCELERATION (PHYSICS); PROPULSION SYSTEM PERFORMANCE; RECTENNAS; NUMERICAL ANALYSIS; ALGORITHMS
