British multinational manufacturerGKN航空已宣布扩张its Risk and Revenue Sharing Partnership (RRSP) with American aerospace manufacturerPratt & Whitneyat theInternational Paris Air Show。
As a result, GKN Aerospace will utilize additive manufacturing to develop the Fabricated Fan Case Mount Ring and the Fan Spacer for the Pratt & Whitney PW1500G and PW1900G engines from its GTF engine family.
“GKN Aerospace’s Technology enables a huge reduction in source material use, and lifecycle energy cost, contributing to reduced CO2 emissions in the manufacturing process,” said Joakim Andersson, CEO of GKN Aerospace Engine Systems.
“This represents the largest fully automated deposition of AM to be certified on commercial aircraft and is a huge milestone for GKN Aerospace in the use of this exciting technology, paving the way for many opportunities to come.”
“这项协议是一个里程碑,它重申the success of the engine participation programs.”
GKN航空航天和普拉特惠特尼
The Pratt & Whitney GTF engine family entered service in 2016. Since then, according to Dave Emmerling, VP, Strategy & Business Development at Pratt & Whitney, the engine “has delivered on its promised ability to reduce fuel burn by 16 to 20%, and to significantly reduce regulated emissions and noise footprint.”
Part of the GTF family, the PW1900G engine which powers the Embraer E190-E2 aircraft, and the PW1500G engine which powers the Airbus A220 aircraft, will be developed in the RRSP with GKN Aerospace. Under the original agreement, GKN Aerospace became responsible for the design and manufacture of the turbine exhaust case (TEC) and intermediate compressor case (IMC) as well as the manufacture of the engines’ low-pressure turbine (LPT) shaft.
现在，扩展合同加强了GKN航空航天参与这些引擎计划，以及公司作为Pratt＆Whitney的发动机部件的长期供应商的作用。此外，GKN航空航天还拥有普拉特和惠特尼的RRSP，用于空中客车A320NEO家庭飞机的组件，以及三菱地区喷气机（MRJ）。
Laser Metal Deposition with wire technology
GKN航空’s additive manufacturing process combines metal wire feedstock with a laser mounted to a robotic arm, i.e, Laser Metal Deposition with wire (LMD-w). This month, continuing a1780万美元的协议with橡树岭国家实验室（ornl），公司委托新型大规模添加剂制造生产细胞 -雷电竞充值细胞2.- 使用LMD-W技术，开发大型飞机组件。
GKN航空is also involved in the EU-Canadian fundedAMOS项目which aims to develop定向能量沉积(DED) technologies for the repair of components used in aerospace.
