"First flight of a Navy unmanned X-plane — that's a huge deal, but it's just one of the many firsts to come out of this program," Engdahl said.
Engdahl还说“这是海军无人验证机的第一次飞行，这可是大事儿，但仍然仅仅是这一项目的开始而已”。
For this reason, the paper put forward a comparable method that transforms all of them to R-X plane.
为此提出了将两者都归算到R - X阻抗圆平面上比较的方法。
Through check, it is found that minimum excitation limit is calculated in P-Q plane, while impedance type loss-of-field protection is analyzed in R-X plane.
“发电厂并网运行安全性评价”要求验证低磁励限制与失磁保护的整定关系，在实际校核中，发现低磁励限制是在P-Q平面进行计算的，而阻抗型失磁保护是在R-X阻抗圆平面进行分析的。
We've got a few more steps before it becomes a full aircraft program, but I do envision a demonstrator or 'x' plane in the next couple of years. We're going to need that to establish credibility.
在它成为一个全面的飞机计划以前，我们还有很多步的研究要做，但我能预见到几年后会有一架展示飞机或“X”飞机出现，让我们可以建立起可信度。
