Cost-Effective Reusable Thermal Protection System for Re-Entry Vehicles

This proposal addresses the long-standing challenge of high-cost, labor-intensive, and low-scalability thermal protection systems (TPS) currently derived from Space Shuttle heritage. As reusable spacecraft become essential for a sustainable low-Earth orbit economy, the need for an innovative, cost-effective TPS is critical. Our project seeks to revolutionize the design, manufacturing, and integration of TPS by leveraging advanced material systems, streamlined production methods, and efficient operational practices. The proposed solution involves developing a multilayer TPS that combines a high-temperature, oxidation-resistant outer layer with an underlying lightweight insulating substrate. By exploring alternative materials such as novel ceramics and metallic composites, our approach aims to achieve superior thermal performance while reducing overall mass and cost. Key to our strategy is the integration of modern manufacturing techniques including additive manufacturing, automation, and microwave sintering. These methods promise not only to reduce lead times and supply chain vulnerabilities but also to facilitate a seamless integration process with the vehicle’s structural components. Phase I will focus on conceptual design, small-scale fabrication, and rigorous testing to validate material properties and thermal performance under simulated reentry conditions. The project will also include a comprehensive analysis of cost reductions relative to heritage systems, ensuring that the final TPS design is both robust and economically viable. Ultimately, this research is poised to deliver a next-generation reusable TPS that meets the demanding thermal, mechanical, and operational requirements of future spacecraft, thereby supporting NASA’s broader goals of sustainable space exploration and commercial spaceflight.
