Abstract:

This report presents the results of the Laser-Heated Rocket Thruster Program, Contract NAS3-19728. The objectives of this program were to 1 perform design and analysis of a 5OOO-kw laser heated rocket thruster 2 design a lO-kw configuration through scaling and design analysis and 3 fabricate and deliver lO.kw experimental hardware thrust chamber assembly, thrust stand, and plasma initiation system. A space vehicle application using 5000kw input laser power was conceptually evaluated. A detailed design evaluation of a lO-kw experimental thruster including plasma size, chamber size, cooling, and performance analyses were performed for a 3.45 X l05 NM2 5O psia chamber pressure and using hydrogen as a propellant. The l0-kw hardware fabricated included a water-cooled chamber, an un-cooled copper chamber, an injector, ignitors, and a thrust stand. Also a detailed design of an lO-kw optical train was performed.
