What Are the Different Types of Thermal Protection Systems?

Highly complex assemblies in aerospace applications can face exposure to severe heat, intense cold, and sudden temperature changes, leading to costly (or dangerous) damage. These assemblies require specialized thermal protection systems (TPS) built for long-lasting, zero-failure applications.

The materials and structural components used in TPS systems are carefully designed and developed to protect critical components in spacecraft from conditions faced during a given mission.

Choosing the right type of TPS for each application can mean the difference between a successful mission and failure.

At TexTech, we create a wide range of Q Shield materials that can support various vehicle requirements and applications. Our TPS solutions include:

• Coated high-temperature felts
• Silica felts
• Rayon fabrics for carbon cloth phenolic applications (e.g., rocket nozzles)
• 3D woven/felt preforms for hypersonic applications
• Reinforced carbon/carbon composites
• Felt reusable surface insulation (FRSI)

Different TPS for Different Missions

Common types of thermal protection systems used in aerospace are:

Heat Shields

One popular form of TPS is a heat shield. Heat shields work as thermal insulators, protecting everything from space vehicles and missile payloads to aeronautic structures and surfaces from sudden exposure to heat. They can even help with aerodynamics, reducing the amount of stress the spacecraft experiences during flight.

Reusable TPS

Reusable TPS can protect vehicles during multiple reentries and work over extended periods. These materials are durable and optimized for weight and cost.

TPS for Hypersonic Flight

When flights go hypersonic or above Mach 5, they are exposed to powerful aerodynamic heat and force that can critically damage exterior surfaces and internal hardware. TPS shields can protect exterior surfaces and keep interior temperatures stable for operation.

TPS for Launch and Assent

Aerospace vehicles and assemblies experience high heat during launch and ascent as well as reentry. The right TPS materials will protect payload fairings and other at-risk surfaces from exposure to high thermal loads.

Choosing the right material can be challenging. We’ve created a selection guide that includes varying Q Shield options and their performance data to help you select the perfect system for your needs. This data set shortens our customers’ design timelines and provides key metrics for modeling the different options.
