AFRL Scalable Panel

• Risks
• Transportable, Lightweight, Deployable Structure
• Alignment and Calibration of Deployed Structure
• Wind Loading of Large Aperture
• Cost of Low Power Panels
• Efficient, Reliable Cooling

• Benefits
• Full Field-of-View
• Affordable
• 30-day Relocation
• Low Power Density
• Efficient
• Enhanced Bandwidth

Transportable, Deployable Structure
Approved for Public Release05-MDA-0971 (28 July
2005)

Summary

• AFRL is investing in modular, scalable,
  lightweight apertures with structural load
  bearing capability
• Primary cost reduction efforts (ManTech) are in
  X-Band due to quantities of X-Band systems
  procured
• Collaboration opportunities also in non X-Band
  systems to increase quantities and reduce cost
