  4. More about… Raytheon • Specializes in defense systems, government and commercial electronics, business aviation and special mission aircraft • Chairman & CEO: Daniel P. Burnahm • $16.9 billion revenue in 2001 • 79,000 employees worldwide • Client contact: Brian Scott, Electronic Systems

  5. Problem Definition • Preliminary design and proof-of-principal prototype needed for a window positioning system to be used in a tank-launched infrared guided warhead

  6. Problem Definition Cont. • Infrared sensor in projectile requires Non-Uniform Compensation to be performed • Necessary to see uniform image • Accomplished by temporarily blurring the scene by shifting the focal point

  7. Non-Uniformity Compensation • Non-Uniformity Compensation never performed at this scale before • Uniform Adaptive Compensation used in the Sidewinder A-A Missile

  8. Seeker Device Layout

  9. Project Needs • Packaged in 0.2” tall by 2.9” diameter cylinder, excluding electronics • Move a 0.352 lbm Germanium lens .04” thick by .6” diameter to cover a photocell array • Lens must stay in position for 1 second, and move in and out of the field in less than 1 second

  10. Project Needs • Require less than 24 Watts at a max of 24 Vdc for less than 1 sec and less than 5 Watts continuous • Lowest mass possible • Be capable of repeated actuation for testing • Thermal Aspects: -320 to 190C Operating, -460 to 630C Storage • 10-15 year storage life

  11. Shock Response Spectra • Launch Conditions • Set Back: 10,000G • Balloting: 3,300G • Set Forward: 2,000G • Flight Conditions • Lateral: 0-3G • Vibration: 5G

  12. Preliminary State-of-the-Art Research • Research on potential methods of generating movement • Micro-motors • Pneumatic Actuators • Solenoid and Non-Solenoid Linear Actuators
