At PC1, our first AMA of 2025 set the stage for a new era of in‐house manufacturing.
Every GT50 and HX50 component is now made under the same roof— from advanced composite laminating and precision aerospace casting to state-of-the-art machining.
15 Apr 2025
Our cutting-edge composite facility is equipped with laser ply cutting machines and digital cure control ovens, while the aerospace casting facility now produces high-grade superalloys and structural aluminium components using both traditional wax injection moulding and modern 3D printing.
In addition, specialised machining centres handle critical parts like fuel spray nozzles and control valves, with a fully calibrated metrology lab actively ‘policing’ each component to guarantee precision throughout the production flow.
GT50 Engine A significant focus of the update was the development of the first GT50 engine. The team shared exciting progress, including the successful test runs of the starter generator (which achieved up to 40,000 RPM), high-speed bearings, and the innovative dual-orifice fuel injection nozzles.
Overcoming challenges such as a minor position sensor error in the starter generator system has allowed the team to refine control algorithms and fully validate component performance across the entire operating range.
Investment Casting and Turbine Blade Production An in-depth look into our investment casting facility revealed the end-to-end process of transforming raw materials into precision cast components. From wax pattern creation and ceramic moulding to advanced heat treatment and post-casting inspections, we’re achieving high-integrity castings for turbine blades, nozzle guide vanes, and bearing housings. Subsequent finishing stages—including EDM machining for cooling slots and precision grinding of fir tree roots—ensure that the turbine blades meet demanding tolerances and performance standards.
HX50 Fuselage and Rotor Blade Progress The update showed improvements in windshield manufacturing, next-generation cabin door designs, and composite fuselage refinements that eliminate vulnerable bond beads and reduce overall weight. Our new composite rotor blades have been engineered to reduce vibration substantially, ensuring that HX50 will deliver exceptional performance and comfort across its operating regime.
With key milestones achieved and further testing of the GT50 engine and associated components scheduled for June, our end-to-end manufacturing philosophy continues to enable us to deliver robust, high-performance aerospace products exactly on budget.
