1. Concepts for Path Correction P07106 METEOR Guidance Group

2. Two categories Cold Jet Uses pressurized gas Fast response High electrical usage No thrust loss On/Off control Heavy Thrust Vectoring Control Surfaces in Exit Flow Slower response Low electrical usage Reduces thrust Proportional control

3. Cold jet parts &consumables –COTS or custom valves and nozzles –Plumbing –Electrical support –Pressurized gas –Electrical power 2 layouts studied –4 nozzle asymmetric –8 nozzle Marotta Thruster

4. 8 valves in 4 pairs

5. 8 jets Fire same direction pairs for pitch and yaw Fire 2 or 4 valves for roll

6. 4 jet for 3 axis control

7. 4 offset jets Fire diagonal pairs for roll control Fire same-side pairs for pitch and yaw Fewest valves but needs even larger High waste of working fluid YawPitch Roll

8. Thrust vectoring Parts & consumables –Actuators –Control surfaces –Linkages and wiring –Electrical power –Some thrust loss 2 layouts considered –Jet vanes –Hybrid vane/tab Historical Application

9. Jet vane 4 control surfaces deflect to divert thrust Constant thrust losses Roll Pitch or Yaw Mounted on Nozzle

10. Hybrid vane/tab 4 pairs of control surfaces move into flow when needed Untested Design Mounted on Nozzle Shape from Above

11. Pitch/yaw and Roll Pitch or YawRoll

12. Interesting Alternative Concepts Flexible Fuel Grain Multiple Nozzles

13. Concept Analysis Selections from Criteria: Jet Vane Jet Vane - Tab Hybrid
