With high-speed wind tests of scale models under way, the blended wing could take flight before 2020.

目前，等比例模型的高速风洞测试正在进行中，预计混合机翼能在2020年前起飞。

A natural way to think of it would be analogous to the saffir-simpson hurricane scale that is based on maximum sustained wind speed.

一种自然的思考方式是比照基于最高持续风力的萨菲尔—辛曾森飓风等级。

Those teams will also be allowed unlimited out-of-season track testing, with no restrictions on the scale and speed of wind-tunnel testing.

The Fujita scale is used to estimate the wind speed of a tornado by the damage the tornado causes.

Tornados are rated on several scales for strength based either on wind speed, pressure drop, or damaged caused, but the updated Enhanced Fujita Scale is the presently accepted scale in the United States.
