Aerospace & Defense
Engineering Reliability Beyond the Atmosphere
In aerospace engineering, every gram of weight and every milliwatt of heat matters. Whether it’s protecting a satellite’s sensitive electronics from the ±150°C fluctuations of low Earth orbit (LEO), or ensuring the structural integrity of a hypersonic vehicle during atmospheric re-entry, thermal management is the boundary between mission success and catastrophic failure.
We engineer Thermal Protection Systems (TPS) strictly focused on SWaP reduction. By integrating aerospace-grade aerogels and polycrystalline ceramics, we enable OEM engineers to hit aggressive Delta-V targets, slash parasitic mass, and ensure survivability during severe thermal cycling and atmospheric re-entry.
Overcoming the Critical Challenges of Flight
Aerospace and defense OEMs face a unique set of "non-negotiable" constraints. We specialize in addressing these high-stakes pain points:
- The "Mass Penalty" of Insulation:
Every additional kilogram of insulation requires more fuel and reduces the available payload. Traditional insulators are often too heavy for modern efficient aircraft and spacecraft. - Thermal Runaway in Avionics:
Compact, high-power electronic suites generate immense heat. In the vacuum of space, convection is non-existent. Without ultra-reliable conductive heat spreaders and dielectric isolation, dense RF modules and processors suffer catastrophic thermal failure. - Acoustic & Thermal Integration:
Modern jet engines and rocket fairings require materials that can simultaneously provide ultra-high temperature insulation and acoustic damping to protect delicate cargo and personnel. - Vacuum Outgassing & Contamination:
In space environments, standard materials can release volatile condensable materials (VCM), which can fog optical sensors or contaminate solar arrays. - Cryogenic Fuel Management:
Managing liquid hydrogen (LH2) or liquid oxygen (LOX) requires insulation that remains flexible and effective at temperatures near absolute zero without cracking.
To assist in your material selection process, the following tables highlight how AIMRSE technologies outperform legacy aerospace solutions.

Weight Reduction in Commercial APU Compartments
A major aerospace OEM needed to reduce the weight of the Auxiliary Power Unit (APU) fire shield. Traditional micro-porous silica was too fragile and required heavy steel cladding.
