Aerofoils

Aerofoils are some of the most critical aeroengine components. Their material capability and geometry directly affect engine performance and fuel consumption.

Aerofoils

The aerospace industry’s constant drive to improve performance and efficiency places increasing demands on aerofoil manufacturing processes.

These improvements must be achieved through cost-efficient manufacturing processes which can meet production targets.

The AMRC with Boeing’s aerofoil platform team, part of the Machining Group, is dedicated to improving the performance and quality of aerofoil machining techniques.


Capabilities

The AMRC Factory of the Future offers a number of machining centres with proven capabilities in aerofoil machining processes. We can also draw on the additional capabilities of our key strategic partners.

Mori-Seiki NT5400

Flexible five-axis mill-turn capability for single blade machining, from a range of inputs including forging and bar stock. Twin spindle and lower turret application allow the development of single-hit machining for complex aerofoil geometries.

Mori-Seiki NT4250 automated cell

Flexible five-axis mill-turn-grind capability for single blade machining from a range of inputs. The NT4250 has been integrated into an automated processing cell combining machining processes with mass finishing techniques (Rösler drag finishing and vibratory bowl) and rapid component inspection.

Starrag-Heckert STC1250 – Starrag-Heckert ZT1000

Large five-axis horizontal milling capability for wide chord fan blade (WCFB) machining as well as integrally bladed disc (blisk) and bladed ring (bling) applications.

Mori-Seiki NMV8000 – Hermle C50

Five-axis mill-turn capability (with additional grinding capability on the NMV8000) for blisk, bling and impeller applications.

Starrag LX051

Five-axis single blade and small blisk / impeller milling capability with the addition of through spindle coolant options including cryogenics (CO2 based), minimum quantity lubrication (MQL), air and conventional high-pressure coolant application.


Research

 

We aim to cover all single and multi-bladed aerofoil applications for aeroengines and for power generation.

We can work with a variety of conditions of supply and machining processes to handle fan, compressor and turbine engine modules.

Our current research areas include:

  • Advanced materials and condition of supply.
  • Advanced component design and tighter tolerance features.
  • Cost-based method of manufacture development.
  • Process control, monitoring and modelling.
  • Green button manufacturing methods.
  • Milling, grinding and surface finishing processes.
