Parker Aerospace 3D prints fuel atomizing nozzles and dual fuel manifold assemblies

China3D printingCalifornia aerospace parts manufacturer Parker Aerospace has announced that it will provide Vericor Power System’s oilfield gas turbine3D printingFuel atomizing nozzle and dual fuel manifold assembly.
Electron beam technology will be used to produce new components, enabling reductions in emissions and part counts while improving manufacturing predictability.

Parker Aerospace offers aircraft manufacturers a range of3D printingparts, including fuel system components and high temperature exhaust valves. Over the past few years, the company has provided parts and maintenance for machinery produced by Airbus, Rolls-Royce and Commercial Aircraft Corporation of China.Gas general manager Steve O’Connor said:
“Working with Vericor to establish specifications and performance parameters helped the PowerGen team gain a clear understanding of the best way to design and manufacture fuel nozzles and manifolds for the TF50F gas turbine. The Turbine Fuel Systems PowerGen Division, a division of Parker Aerospace, is alsoParker Hannifinof a department.

“By utilizing additive and electron beam welding manufacturing methods and removing the limitations of traditional manufacturing techniques, we are able to provide higher performance systems that require fewer parts, which also provides cost advantages to our customers,” added O’Connor. .According to China3D printingInternet understand,
Made by Parker Aerospace3D printingThe first contract for a fuel nozzle, but it is not an industry first. GE’s LEAP jet engine fuel nozzle is one of the most well-known additive manufacturing success stories in aerospace.In fact, last year GE announced that it had developed its 30,000th3D printingnozzle.

Electron beam welding3D printingTechnology Has Better Part Performance

Parts produced for Vericor’s TF50F oilfield gas turbine will be fabricated using Parker’s fully automated electron beam welding technology. Welding takes place in a high-purity vacuum chamber, resulting in a clean and predictable welded joint free of oxides and nitrates. Electron beam welding also eliminates the need for multi-pass welding, greatly reducing shrinkage and distortion.
Parker Aerospace claims this approach improves the fuel flow path within the nozzle, resulting in better fuel atomization and distribution within the engine combustion chamber. It also improves combustion performance, improves fuel efficiency and reduces emissions.

Control of fuel atomization and fuel droplet size is critical for efficient gas turbine engine combustion, and a key driver for droplet size optimization is the geometry of the flow path inside the engine’s fuel nozzles. Parker Aerospace also claims that compared to conventionally manufactured nozzles,3D printingThe TF50F fuel nozzle will reduce the number of parts by 30%.CurrentlyTesting and validation of the nozzle and manifold assembly is now complete, manufacturing is underway, and it is understood that parts will be delivered to Vericor for use in early Q3 2019.
