AAE450 Spring 2009 Descent Trajectory Hover Trajectory LD Code Integration John Aitchison March 5 th, 2009 [John Aitchison] [Mission Ops]

AAE450 Spring 2009 [John Aitchison] [Mission Ops]  Finalized Descent Trajectory {all payloads} –De-Circularize → Retro→Throttle Down Coast→Vertical –Steering program a possibility Does provide savings if we need to start descent at altitudes approximately >25km Dependent on TLI/LD iterations  LD Code Integration {all payloads} –Complete, will be finalized with updated code from each group  Hover Trajectory {arbitrary payload} –Near complete, small attitude control adjustments needed 2

AAE450 Spring 2009 [John Aitchison] [Mission Ops]  Arbitrary Payload Analysis –Falcon 9 LLO Deliverable: ~5700kg –Falcon 9 H LLO Deliverable: ~18000kg  Mass Deliverable to Lunar Surface –LD Budget available for Structure, Power, Thermal, Comm, Attitude Inert, Usable Payload –Assuming descent engine thrust & attitude thrust scale accordingly Mass in LLODE ThrustPropellantInert PropLD Budget 5,700 kg44,000 N2,825 kg342 kg2,532 kg 18,000 kg143,950 N8,722 kg998 kg8,280 kg 3
