How Automated Tape Laying Is Transforming Thermal Protection Systems for Hypersonic Glide Vehicles

As demand grows for hypersonic vehicle technology, so does the need to produce Thermal Protection System (TPS) materials with greater quality, consistency and performance—areas where Automated Tape Laying is poised to make a significant impact.

Key Takeaways

• Textron Systems is advancing hypersonic Thermal Protection Systems (TPS) with an Automated Tape Laying (ATL) process that improves quality, precision and repeatability in composite heatshield manufacturing.
• Textron Systems’ ATL approach strengthens carbon/carbon components, reduces delamination and increases production yields.
• The Textron Systems ATL process helps deliver more reliable TPS structures for extreme‑temperature hypersonic environments while decreasing cost and material scrap.

Advancing Thermal Protection Systems with Automated Tape Laying Technology

Hypersonic glide vehicles face some of the most extreme environments of any aerospace system. As these vehicles travel at velocities greater than five times the speed of sound, the air around them compresses and heats dramatically, creating temperatures capable of compromising even advanced materials. To survive these conditions, hypersonic glide vehicles rely on Thermal Protection Systems (TPS). These systems are specialized barrier structures engineered to shield them from intense heat and maintain structural integrity.

Textron Systems has long supported government and industry partners in producing high‑performance TPS materials. Today, Textron Systems is investing in next‑generation manufacturing capabilities designed to improve the quality, consistency and performance of carbon‑based TPS structures. These manufacturing capabilities are developed through a patented Automated Tape Laying (ATL) process, specifically tailored for carbon composite heatshields.

From Manual to Automated: A Step Forward in Quality and Efficiency

Traditional tape‑wrapping techniques for composite heatshields involve significant manual labor, which can introduce variability and make it harder to control quality. Textron Systems’ modified ATL process changes that.

ATL offers several advantages over manual tape wrapping, including:

• Process data collection and quality control during the preform fabrication process
• Low part‑to‑part variability due to automation
• Precision and dimensional stability after cure and densification
• The ability to work with many types of prepreg carbon and silica fiber tapes

The automated process increases reliability; reduces material scrap compared to manual methods and enables nearer‑net‑shape manufacturing—all of which help shorten production timelines and decrease costs.

Strengthened Structures and Higher Yields

Textron Systems has developed a proprietary enhancement process that improves the strength of the interply composites produced through ATL. This enhancement is especially important for carbon/carbon (C/C) components, which are used in the highest‑temperature sections of hypersonic vehicles.

TPS preforms manufactured using Textron Systems’ ATL process can drastically reduce delamination in densified C/C parts and increase yields for these critical and expensive structures.

A Versatile TPS Manufacturing Capability

The temperature range faced by hypersonic vehicles varies by mission and vehicle design. To meet these diverse needs, Textron Systems manufactures:

• Silica phenolic for moderate‑temperature equipment
• Carbon phenolic for higher‑temperature applications
• Carbon/carbon for the most extreme thermal environments

When paired with ATL’s reproducible precision, these material capabilities deliver TPS components engineered for performance, durability and mission reliability.

Preparing for the Future of Hypersonics

Looking ahead, Textron Systems plans to incorporate in‑process nondestructive evaluation (NDE) into the ATL workflow, enabling real‑time quality monitoring and further improving yields. Due to its flexible nature, the automated system can also be adapted to a wide array of hypersonic-relevant geometries with minimal difficulty to support evolving customer needs.

Textron Systems continues to collaborate closely with government and industry partners to address the nation’s most pressing challenges in advanced materials and hypersonic system development.

Frequently Asked Questions (FAQ)

• Q: Why is carbon/carbon material so important for hypersonic vehicles?
  • A: Carbon/carbon is used where heat is highest, and improving part durability—such as by reducing delamination—directly enhances mission safety and material longevity.
• Q: What types of thermal protection materials are used for different temperature ranges?
  • A: Textron Systems supports multiple TPS types—silica phenolic, carbon phenolic and carbon/carbon—to address a wide spectrum of thermal environments and system requirements.
• Q: How will future automation and in‑process inspection technologies impact TPS production?
  • A: Integrating real‑time nondestructive evaluation (NDE) into ATL will help manufacturers detect issues during production, reduce scrap and improve the overall efficiency of TPS manufacturing.
• Q: What challenges do hypersonic vehicle designers face when selecting Thermal Protection System (TPS) materials?
  • A: Hypersonic vehicle designers must balance extreme thermal requirements with weight, manufacturability and reliability. Each vehicle profile experiences unique heat loads, meaning materials must be tailored to mission‑specific conditions while still supporting efficient production and integration.
• Q: Why is reducing delamination in carbon/carbon components so important?
  • A: Delamination can compromise structural performance, particularly in components exposed to extreme temperatures. Improving interply strength reduces the likelihood of failure, increases ablation performance and usable yields and minimizes production time lost to rework or scrap.
• Q: What problem does Automated Tape Laying (ATL) solve in manufacturing TPS components?
  • A: ATL reduces variability from manual fabrication, increases uniformity and quality and helps manufacturers produce more consistent heatshield components for hypersonic systems. The automated process also increases production throughput and reduces manufacturing time and cost.
• Q: How does ATL improve the performance or reliability of hypersonic vehicle materials?
  • A: ATL improves layer placement and structural quality, which supports better performance at extreme temperatures and reduces the amount of ablation and the risk of structural failures.
