The Redwire BowSAW Deployable Solar Array Wing is a space power generation solution for small satellites. The BowSAW is a high-performance, reliable, scalable, versatile solution for deriving electricity from sunlight, offering a plentiful power source for running high power payloads, sensors, active heating, cooling, telemetry, and spacecraft propulsion applications.

The BowSAW Deployable Solar Array Wing provides the following benefits:

  • High-Performance: utilizes a lightweight, low volume, stiff, and low-cost deployable backing structure
  • Reliable: passively driven, partially retractable and sequenced deployment reduces risk
  • Scalable: performance is maintained through a wide variety of wing sizes ranging from 150 W to 6,000 W
  • Versatile: multiple types of solar cells can be deployed, enabling optimization for reliability, mass or cost

Applications of the BowSAW include:

  • High Power Payloads
  • Sensors
  • Active Heating / Cooling
  • Telemetry
  • Spacecraft Propulsion

Customers select the BowSAW for the solar array applications because the solution offers:

  • Power-rich capabilities - The BowSAW packs signficant power in a small space using a low-cost deployable backing structure.
  • Usable on any spacecraft - The BowSAW utilizes its distributed lattice structure to maintain high performance across many wing sizes. BowSAW is SADA compatible, and stows within a small footprint that allows flexibility with spacecraft layout.
  • Optimized for many missions - For missions ranging from the mass-constrained Mars transit, or a cost-constrained LEO constellation because the flexible BowSAW power solution can deploy any type of solar cell.

Solar Arrays are export controlled through an ECCN (Export Control Classification Number) issued by the United States Department of Commerce, ECCN 7A104. Export shipment requires successful application for an export license. Redwire is AS9100D/ISO 9001 certified.
