  1. Adjunct Missile Seeker Deployment Mechanism Concept Review University of Arizona Raytheon Missile Systems

  2. Team Members • Thomas Jefferson • Material Sciences • Ryan Moore • Mechanical Engineering • Philip Pierson • Optical Sciences • Scott Nielsen • Optical Sciences • Karl Heiman • Aerospace Engineering • David Kraemer • Electrical Engineering

  3. Outline • Problem Statement • Customer Needs • Design Constraints • Design Ideas • Concept Selection • Plan of Action

  4. Problem Statement • Design an Adjunct Seeker Deployment Mechanism (ASDM) that will deploy an Infrared (IR) seeker in the final stages of missile flight.   • Mechanism must: • Minimize changes to existing airframe • Minimize the drag on the missile • Maximize the field of regard (FOR) of the seeker

  5. Customer Needs I • Mitigate new threats • Utilize existing components • Optimized for different system • Minimize changes to proven systems • Autopilot • Airframe • Identify trades and risks of proposed design • Implement a reliable design

  6. Customer Needs II • Use an existing IR Seeker • Minimize System Weight and Volume • Survive Thermal Environment • Storage • Flight • Rapid Deployment

  7. Design Space Circuit Cards

  8. Design Constraints

  9. Design Components • Deployment method • Must meet deployment time restrictions • Seeker orientation • Target must be visible until impact • Door mechanism • Affects previous design characteristics

  10. Deployment Mechanism

  11. Seeker Orientation

  12. Door Mechanism

  13. Concept Selection Note: This is only an example of the Selection Process

  14. Concept Selection I Slide Rail System Pros • One direction of Movement • Indexed Direction Cons • Lubrication required IR Seeker MissileCross-section Slide Drive Track System Circuit Card Space Utilizes: Slide Drive System, Any Seeker, maximum length available

  15. Concept Selection II Pivot Arm Pros • Single Motion • Easy to Implement Cons • Large Deceleration • Large torque for movement Torsional Spring? IR Seeker Pivot Arm Circuit Card Space Missile Cross-section Utilizes: Pivot Arm, Any Seeker, Few moving parts

  16. Door Cut-out Pivot Axis Missile Cross-section Circuit Card Space Concept Selection III Seeker Rotation Pros • Simple control of movement Cons • Volume for motion • Torsional force required IR Seeker Utilizes: Seeker Rotation, Any Seeker, Few moving parts

  17. Plan of Action • Next two weeks • Flesh out design details • Trade analysis • Identify risks • Next two months • Design analysis • Finalize design

  18. Summary • Evaluated our customer’s needs • Presented rough ideas • Eliminated ideas based on customer needs • Came up with our preliminary designs
