In-Situ Fabrication of Spacecraft Heat Shields
Current state-of-the-art methods for the fabrication of thermal protection systems (TPS) for spacecraft are costly, labor-intensive, and limited to on-Earth production. To address these shortcomings, Mainstream, in collaboration with Virginia Tech is developing additive manufacturing (AM) system for the in-situ fabrication of a high-heat-flux ablative TPS.
The Spacecraft Thermal protection system Additive Manufacturing (STAM) system utilizes a robotic arm that is programmed to allow for heat sink material deposition on any complex geometry of a spacecraft. The STAM system can autonomously fabricate a full-scale conformal TPS directly onto the spacecraft exterior.
Improving heat shield performance and lowering cost is critical to future missions, including manned missions to the Moon and Mars. In addition, hypersonic vehicles experience high heat fluxes and temperatures associated with hypersonic flight. These vehicles would also benefit from an improved thermal protection system.
