  1. A new concept for exo-atmospheric KV with large divert capability Dr. Galya Goldner , Dr. Joseph Hasson MLM, IAI

  2. Contents BM employment process System trade-offs KV design analysis Divert system alternatives A new design Concept Divert capability Sub-systems Design example Typical weight budget Summary

  3. Trade –off BM employment process Target Detection Detection and Tracking Performance Target tracking Interceptor Launch Interceptor Performance Discrimination: • Ground sensors • Airborne sensors • On-board sensor

  4. BMD system components • Detection & Tracking Systems • Satellites • Ground/sea radars • Air Born Sensors • BMC • Launchers and missiles

  5. Interceptor Poor slow large time constant small divert capability High performance small & fast agile high divert capability Detection and tracking sensors Exceptionally efficient very large detection range high tracking accuracies Released requirements shorter detection range released accuracies decreased discrimination range System Trade – Offs

  6. Exo-atmospheric KV design - analysis • Thermal protection, aerodynamic shape or window cooling are not required. All covers are ejected before divert motor ignition. • EOS requirements • large detection range • high resolution and accuracy • Accurate navigation system • Low weight • High agility • High performance divert system • Design goal – simple and inexpensive

  7. LOS Target trajectory Interceptor trajectory

  8. Divert system alternatives Liquid fuel Gel Gas generator Solid DACS

  9. Ordinary rocket motor with flexible nozzle EOS mounted on 2-axes gimbals The angle between the sensor LOS and the body – according to the required divert. Near constant acceleration LOS attitude Thrust New Design - Concept This KV design is protected by: Israel application 162863 issued in Israel at Jul, 5th 2004, PCT application No. PCT/IL2005/000712, European application No 05759181.0 and USA application No.11/631501

  10. Divert capability analysis (1) Divert Capability Tburn

  11. Divert capability analysis (2) ΔV Minertial to Mtotal ratio Divert Capability Minertial to Mtotal ratio

  12. KV design (1) Reflecting Optics FPA, cooler & MEMS sensors Batteries, signal processor, GPS, computer & drivers Divert motor Flexible nozzle

  13. KV design (2) At the last stage of the end game the angle between TV and LOS approaches zero LOS Target trajectory Interceptor trajectory

  14. Summary A new concept of KV was presented Main features Simple design based on mature technologies => reliable and inexpensive Large divert capability and high agility => released requirements for detection and tracking systems Thank you !
