# Propulsion simulation tools

> Simulation + CAD + analysis tools for rocket + satellite propulsion.

**Sector**: [Space Tech](https://signals.gitdealflow.com/niche-down/space-tech)  
**Build cost**: Team-sized build  
**Deal velocity**: Trickle — one deal per quarter

## Why now

Propulsion R&D is the slowest part of space dev. Simulation accelerates it 10x.

## What the signal looks like

Repos with CFD adapters, propulsion-modeling libraries, and CAD-integration frameworks.

## Public examples

*Public projects + categories only — we never name founders tracked inside the paid product.*

- Rocket Lab internal tooling
- ANSYS + AI adjacency
- Open-source propulsion-sim libraries

## What this displaces

A custom CFD + manual analysis.

## Our build-vs-invest call

Niche, research-heavy. Fund only with aerospace + simulation team. The moat is accuracy + ecosystem.

## Frequently asked

### Buyer?

Aerospace engineers + space startups.

### Pricing?

License + support.

### Defensibility?

Accuracy + ecosystem.
