COMBUSTOR.
a steady fire in a hurricane
The annular combustor has to hold a stable flame in air moving at tens of metres per second, burn every drop of fuel, and deliver an even temperature profile to the NGV. Rows of primary, secondary and dilution holes set where the air goes in and how hot the gas gets.
An even exit temperature profile protects the NGV and turbine more than any alloy upgrade.

Materials
Hastelloy X
Oxidation resistance and weldability in thin sheet for the liners.
Inconel 625
Fuel manifold and injector parts, printed or machined.
How it is produced
Designed by Vector Dynamics, produced by qualified manufacturing partners to our drawings.
- 01
Laser-cut sheet
Liner blanks with all hole rows cut flat, then rolled.
- 02
Forming & TIG welding
Rolled, seam-welded and sized on a mandrel for concentricity.
- 03
Printed dome option
LPBF Inconel dome with integrated swirlers for later builds.
- 04
Heat treatment
Solution anneal to relieve forming and weld stresses.
- 05
Flow check
Injectors flow-matched so every one delivers the same fuel.
and then we check it
- Hole pattern optical check
- Weld X-ray on seams
- Rig ignition & exit-temperature traverse
