Aerospace. Done by the model.
Aether covers ascent aerodynamics, structural margin, aeroelasticity, electromagnetic signature, thermal protection and fatigue under a single foundation model. From wing-body cruise polars to hypersonic re-entry to launch-vehicle stage separation — every loadcase your flight-readiness review needs to clear, in one project file. One aerospace prime retired a $1.8M annual CAE renewal across two quarters.
What the model actually computes.
These are the workloads the AI runs in aerospace — rendered live in SVG. Each panel is the geometry the model is reasoning about, the physics it solves for, and the validation it lands against measured reality.
Aether is the AI doing the aerospace work.
Three things to know about the AI underneath every workload on this page. We aren't building a chat surface for your team — we are training a foundation model that plans, runs and reports.
The AI does the discipline
Not a chat interface over your engineers. A foundation model that plans the study, picks the method, runs the agents, validates against measured reality and writes the report. The same shape an experienced practitioner would follow — done by the model.
One model, your context
We don't ship a sibling model per industry. The same Aether weights serve every discipline, but the agents on top are trained against your standards, your historical data and your regulatory posture.
Reality is the regulariser
We train on simulation, instrument and design data — not scraped text. The model gets better the more reality it touches. Reality is what tells it when it's wrong.

The work, done by Aether.
These are the workloads Aether already runs in aerospace. Not a wish-list. Each ships with validated benchmarks and traces a senior engineer can read end-to-end.
- 01
External aerodynamics
RANS / LES / DES across the full speed envelope. Wing-body cruise polars within ≤1.0% deviation; rotorcraft, propellers, hypersonics on the same model.
- 02
Launch & re-entry
Ascent CFD with reacting-flow combustion, stage-separation 6-DOF dynamics, TPS thermal under simultaneous heat and chemical flux. Re-entry ablation and recession resolved.
- 03
Structural margin & fatigue
Static, modal, nonlinear contact, fracture, XFEM, crash — coupled to fluids where useful. Notched-bar fatigue Pearson 0.92 vs measured life.
- 04
Electromagnetics & signature
Antenna, radar cross-section, SI/PI for avionics, EMC. The accuracy of the leading commercial full-wave tools without the licensing.
- 05
Aeroelasticity
Flutter, divergence, gust response, limit-cycle oscillation — coupled fluid-structure on one mesh. Certification-grade margins by construction.
- 06
Hypersonics
Real-gas thermochemistry, shock-boundary-layer interaction, transition prediction. Mach 5–25 with the same foundation model that handles subsonic cruise.
“We are building the AI that does aerospace — not the one that talks about it. Aether doesn't ask your engineers to drive its solvers. It runs the work, validates the artefact and writes the memo.”
The stack today.
The typical stack in aerospace — a half-dozen seven-figure renewals stitched together with internal glue code. We replace the spine; we don't touch the niches that work.
The agents in the mix.
Aether coordinates these specialist agents for aerospace. Each is independently deployable, but the coordination — and the foundation model underneath — is what makes them more than a folder of scripts.
How we ship into regulated aerospace.
The pieces that matter to procurement, security review and the regulator. We ship into industries where the boundary is real and the audit is unforgiving.

Questions about aerospace.
What does Aether replace in aerospace?
The incumbent stack here — Structural FEA, Computational fluid dynamics, Full-wave electromagnetics, Explicit-dynamics crash codes and more — collapses into one model and one project file, with Aether for engineering doing the work under one safety story.
What outcomes should we expect?
62% (wall-clock reduction at iso-accuracy); 1.8% (drag error vs flight on launcher ascent); $1.8M (annual CAE renewal retired) — scoped to your workload and measured against your own acceptance criteria.
How does a pilot work?
Three to eight weeks against a workload and a win condition you co-author. We run alongside your incumbent stack on real cases; if we aren't better on the metric by quarter end, the rest of the quarter is on us.
Can it deploy inside our boundary?
Yes — managed, in your VPC, on-prem or fully air-gapped on Aether Cloud, with the audit trail and provenance the regulated parts of this work require.
The AI is ready for aerospace.
Send us the workload that hurts. We'll come back with a scoped pilot — three to eight weeks, win condition co-authored. If we aren't better on the metric by quarter end, the rest of the quarter is on us.
