Goals for the FLOAT Team

• Ultimate Goal of Research
• A successful test will provide motivation for
  increased research into FMCs
• KC-135 Test Objective
• To design a control system that, after an initial
  disturbance, will be able to return the apparatus
  to its original position within 20 seconds

4

• Fluid Loops and Pumps
• Accelerate Fluid to generate a change in angular
  momentum
• Apply torques over time to negate disturbance
  effects

• Accelerometers
• Read acceleration rates of 6 faces
• Input voltages to control system corresponding to
  accelerations

• FieldPoint
• Stand-alone control system
• Integrated modular input/output distributor
• 3 modules
• Control module
• Input module
• Output module

• Batteries
• Supply power to control module
• Control module distributes and regulates power
