AX-40 turboshaft
A light shaft engine for medevac and survey aircraft.
Axiom Turbines / Propulsion / Derby
Built apart. Run as one.
A small-engine maker that publishes the drawings. The turbine on this page starts in pieces and comes together as you scroll, then spins up to speed.

Stage 01 / Parts
Eighteen blades, one hub, three rings.
Each part is made on a separate line and signed off by the person who machined it. On this page they hang apart so you can count them.
Stage 02 / Fit
Tolerance is the product.
Blades seat to within four microns. We do not claim that to sound good. It is why the engine can turn faster than the one it replaces.
Stage 03 / Spin
Then it earns its heat.
At speed the blade tips pass through gas hotter than their own melting point. The metal stays solid because the air film is doing half the work.
Numbers, measured.

Programs
Three engine programs. Each one ships with its test data.
02
AX-90 auxiliary
A compact power unit that starts cold in seconds.
03
AX-12 micro
A turbine small enough to carry, loud enough to prove a point.
Seventy engineers, one test cell.
We work out of a former foundry in Derby. Every engine runs on our own test stand before it goes anywhere, and the logs stay with the customer.
