  2. Launch Plans • Organizations • Huntsville Area Rocketry Association (HARA) with Field in Manchester, TN or Bragg Farms, Toney, AL • Phoenix Missile Works with Field in Childersburg, AL • Subscale/Component Tests • February 8-9: Childersburg, AL • March 8-9: Childersburg, AL • March 8: Manchester, TN • Full Scale Tests • March 16: Bragg Farms, Toney, AL • April 5-6: Childersburg, AL • April 13: Manchester, TN • April 20-21: Bragg Farms, Toney, AL

  3. Supersonic Design Considerations • Superheated Skin • Aerodynamic Forces • Rigidity

  4. Subscale Plans • Modified ARCAS kit with Nose Cone Profile • Level 2 Motors • Simulate high G loading • Test Sensors

  5. Motor • CTI M4770 • Complex Motor Assembly • Separate Glue/Epoxy • Time Dependent • Jason Winninghamwill assemble

  6. Launch Rail • Rail Buttons • 1” • Locations • Lower Button – Approximately Fin’s mid chord. • Top button – 24 inches above lower • Rail • 8ft • 1in • Rail Exit Speed – 131ft/s

  7. Descent

  8. Drift

  9. High G Considerations • Materials • 3-D printed material brittle • 6061 Al used at critical interface points • Sensors • Subscale ARCAS test launches with similar conditions • Inspect parts for damage • Check for usable data

  10. Payload Bay • Build envelope • Size defined by subscale Nanolaunch dimensions • Preliminary designs allow for some size increase • Dielectrophoresis improvements, no significant volume increase • Payload at or Close to CG • Dielectrophoresis • Part of Nanolaunch • Forward payload • Radio and tracking • Additional Nanolaunch Payload

  11. CRW Safety Plan • MSDSs, SOPs, and State and Federal regulations. • SOP reviews. • CPR/ AED training. • Facility usage policies.

  12. Parachute Design References • FAA Rigger Handbook (344pages) • The Parachute Recovery Systems Design Manual (T.W. Knacke). (~730 pages) • Two Parachute manuals on hardware, materials, sewing, equipment, etc…

  13. Dielectrophoresis • Problems • Cryogenic boil off – Muratov (2011) • Loss of useable propellant • Vapor bubbles develop • Liquid collection for engine restart – Blackmon (1965) • Solution • Non-Mechanical fluid manipulation device • Consolidate fuel away from tank walls to reduce heat transfer • Easily collect fluid at key locations while reducing dangerous vapor regions

  14. What is Dielectrophoresis? • Gradient : [∂/∂x, ∂/∂y,∂/∂z] • Polarity Independence Uniform Electric Field Non-Uniform Electric Field • 2: Blackmon, James. Collection of Liquid Propellants in Zero Gravity with Electric Fields. Journal of Spacecraft and Rockets, Vol. 2, No. 3, 1965. p 3.

  15. Experiment Fluids • Experiment fluids with comparable dielectric constants to common fuels • Common fluids for comparison of dielectric constants • Peanut oil chosen • Highest dielectric constant of experimental fluids • Theoretically most responsive to dielectrophoretic force

  16. Mass Statement

  17. Supporting Personnel • Tony Hall • PRC Test Engineer • 10 Years of Experience • Jason Winningham • NAR/TRA Level 2 • HARA Member • UAH Employee • Previous NASA Rocketry Workshop Leader • Amit Patel • PRC GRA • HARA Member • 2012-13 CRW Project Manger • NRA / TRA Level 1 • Current Team Member • Dr. Robert Frederick • PRC Director • UAH Faculty for past 20 years • Propellants and Energetics • USLI Academic Advisor • Dr. David Lineberry • PRC Research Scientist • 10 Years of Experience • NAR / TRA (Level) 1 • NSL Course Instructor
