GE对T901单轴的介绍,简单、可靠、省钱,重量没变化多少,功率还大幅提升50%。八爷,GE砸90亿米,为了菌方5亿多米的合同,是不是有更长远的考量?这投资后期能赚回来嘛?
下面一段介绍文字:
To meet the Army’s ITEP requirements — 50 percent more power and 25 percent better fuel efficiency — the engine needs better compression (a higher pressure ratio) in an architecture that is the same size as the current T700 engine. GE Aviation’s top engineers evaluated single and dual-spool engine designs to meet this challenge and determined that the required performance can be met with GE’s 3D aerodynamic technologies without adding additional spools. Additional spools only add more mechanical complexity and drive up risk. GE’s T901 engine meets the Army’s performance requirements by tapping into GE’s impressive stack of proven commercial technologies, including additive manufacturing, ceramic matrix composite (CMC) components, sand tolerant technologies, advanced cooling technologies and industry leading prognostic and diagnostic tools. We’ve invested $9 billion in maturing these technologies over the past decade to drive down risk, and these technologies currently fly in commercial aircraft, safely transporting passengers all over the world every day.
