US Patent #12,715,621
The mission
Next-Generation Atmospheric Reentry Technology
Active Reentry Systems is currently in the development phase of its newly-patented adaptive, gas-exuding heat shield that eliminates replacement and refurbishment of current technology heat shields,enabling a previously unachievable relaunch cadence.
PROPRIETARY IP ASSETS
Protected, Defensible Space Hardware Architecture
Our technology (protected under US patent law and pending internationally under the Patent Cooperation Treaty – PCT) replaces passive, single-use ablatives and heat shield tiles with a dynamic gas exudation network that neutralizes atmospheric heat flux while eliminating post flight tile maintenance and wholesale heat shield replacement.
The technology in action
Passive Shielding vs. Active Shielding
When a seal fails on a passive heat shield, hot gas burns straight through. With active shielding, barrier gas flows out through the same gap and keeps the plasma off the structure. Tap any image to see it full size.
01 / Without active shielding
Seal failure means burn-through.
Hot plasma finds the weak spots in the seal and burns through the flap, causing severe damage to the ship body.
02 / With active shielding
Same seal failure. No damage.
Barrier gas flows out through the failed seal. No erosion of the structure and no hot gas incursions.
03 / Space capsules
A barrier layer across the whole heat shield.
A gaseous barrier layer forms along the entire face of the capsule and holds the reentry plasma away from the surface.
04 / Flight control surfaces
Protection that moves with the flap.
The gaseous barrier layer follows flight control surfaces through the hinge line, so moving parts stay protected too.
Who are we
About Active Reentry Systems
Active Reentry Systems is an aerospace technology company pioneering active thermal protection architectures for atmospheric entry, and orbital return. Engineered to replace heavy, single-use ablative materials and fragile ceramic tiles, our technology utilizes a dynamic gaseous boundary layer to shield spacecraft hulls and deflect extreme plasma shockwaves. By combining real-time flight control automation with advanced additive manufacturing, Active Reentry Systems dramatically reduces vehicle heat shield mass and eliminates post-flight turnaround maintenance—delivering a fast relaunch cadence thermal protection solution for the modern space economy.
