As the aerospace industry evolves with a renewed focus on space travel, there is a growing need for innovation in the area of thermal protective systems (TPS). Even as older systems are refined for viability, new systems must be carefully designed to meet the demands of new atmospheres and multi-launch vehicles.

Developing such new technologies is far from easy given that aerospace requirements are necessarily stringent. Complying with industry regulations often means identifying new manufacturing techniques that push beyond current capabilities to find solutions that are safer and more practical.

As interest in space travel grows once more, Tex Tech is leading the push for customized hybrid TPS systems to protect vessels from re-entry heating.

How to Prevent the Dangers of Re-Entry Heating

Re-entry has always been one of the most challenging aspects of space flight. As an object falls through the earth’s atmosphere, it experiences intense friction. Compound that friction with a fast re-entry speed and a spacecraft can experience temperatures of >3,000° F as the air around it compresses into plasma. A TPS protects astronauts and internal equipment from these extreme temperatures.

There is no single thermal protective system design that accounts for all flight variables, but all systems will include a lightweight heat shield that dissipates the heat while insulating the occupants. A well-designed TPS reflects most of the heat back into the atmosphere or sheds it away from the vehicle, preventing any damage to the interior of the craft.

Advances in material science have led to the development of many different synthetic materials to perform this job, each varying in weight and temperature resistance capabilities. Selecting the best materials for a heat shield or TPS requires a careful evaluation of applicable heat zones, heat fluxes, and mechanical forces that will be present during re-entry.

In most cases, a curated selection of multiple materials will be necessary since the forces experienced during re-entry are not uniform. The nose of the craft, for instance, experiences substantially more heat and pressure, so the material selected for that region must withstand higher temperatures.

Types of TPS Materials

Tex Tech specializes in the manufacture of flexible, graded TPS structures. For each project, we assess the performance requirements carefully to select an appropriate combination of TPS materials from the following:

  • Needle-punched felt
  • Woven fabrics
  • 3D woven/braided fabrics
  • 5D assemblies
  • Unidirectional tows reinforcement
  • Coatings
  • Lamination
  • Hybrid fabrics
