AMCOM MK66 guidance module Assessment and progress made

New progress Acquisition of Garmin etrex Legend portable GPS with RS-232 interface for simulation purposes Allows for creation of accurate GPS position information simulation model

New Progress (cont’d) Thermal/Lithium battery manufacturer specifications and power profiles (EaglePicher) Initial design phase of power transitioning system (Bus power to thermal/Lithium battery) Detailed specifications on new IMU Confirmation of interface specifications

Altera Initial system interfacing and soft-core setup Physical interaction schematics EECE 277 project integration

Desired outcome Mechanically functional model External logic control (Nios devel. Kit) External GPS and IMU simulated data Both GPS and IMU will be physically simulated in the constructed model; data from GPS and IMU will be simulated from PC Electromechanical arrangements Servomotor control interfacing, detonation systems, power conversion and transition

Embedded system reference diagram Altera Nios GPS (or PC) Hydra missile body (contains battery, servomotors, fins, etc.) PC (IMU, RMS simulated data)

ME Timeline Begin construction of finalized design components Missile Tube/Outer Shell Machine Spline Fittings Machine Tube Threads Finalize Fin Deployment Design and Create 3-D Rendering Simulation Present Findings to Amcom Source Materials Begin Construction of finalized design Fin Deployment Inner Frame

ME Timeline Canard Deployment System Construction Design Finalization One Month Two Months Present Outer Shell Construction Simulation and Amcom Presentation

Finalized Designs Missile Tube/Outer Shell Spline fitting Threaded end Internal Framework Constructed to accommodate thermal battery, IMU, GPS, servomotors, canards, wiring, and linkages

Fin Deployment Front

Fin Actuation Features: Direct Drive Gear directly linked to servomotor via flex cable Minimizes moving parts High torque rating

Fin Actuation Features (Cont’d) 2. Gearbox Compact Design Gear Reduction (most servomotors require reduction of speed) Non-backdriving gears allow for highly accurate control
