However, none of the submitted designs were considered any further by the Air Force, mainly because the aerodynamic configurations and the bypass ration of the turbofans were considered inadequate.

然而，美国空军没有更多任何一个提交的设计，主要的原因是空气动力结构和涡扇发动机的旁路配给量被认为不合适。

For example, it may prove difficult to cope with the in-furnace aerodynamic characteristics resulting from the use of a swirl burner on the arch-crown of the W-shaped boiler. In such a case one will not only be deprived of the advantages attributed to the use of the swirl burner but also suffer from a multitude of troublesome issues.
