Lunar Lander Propulsion System 100 g, 10 kg and Arbitrary payload cases ThaddaeusHalsmer Thursday, March 12, 2009 Propulsion System Sizes, Performance and Power requirements Propulsion system cost estimate Designed 10 kg payload hopper engines Worked jointly with SaadTanvirto complete propulsion system sizing codes for all three payload cases Thaddaeus Halsmer, Propulsion
(4) ** numbers on this page are a result of engine sizing scripts written by SaadTanvir & myself. Credit must also be given to John Aitchison for its integration into the Ops trajectory code and many iterations to produce final sizing (3) (1) (2) Stick is 6.5 feet high, same as a standard doorway Thaddaeus Halsmer, Propulsion
1) Propulsion system costs • Not including R&D/Testing to meet reliability requirements • Assumed $10000/kg Integration/manufacturing cost • Propulsion System Power Requirements • Power for fluid control systems Thaddaeus Halsmer, Propulsion
