RANGE DISCIPLINE.

Ardea‑7 is our longest airframe yet: a 4.1-metre, dual-deploy research vehicle built around a fictional N-class composite motor. Every structural joint has two witnesses. Every wire has a tug test. Every launch has a no-go.

Margins Before Mythology

THE FINS
MUST STAY.

At peak dynamic pressure, beauty is irrelevant. The fin sees air as a load, the root sees load as a question, and the answer must remain inside the laminate.
