Nosecones 鼻锥 

Proper use of a microphone with a nosecone is to aim the nosecone towards the air flow. The nosecone has an inner threading and is installed by replacing the protection grid with the nosecone.

正确使用带有鼻锥的麦克风是将鼻锥对准空气流动。鼻锥具有内螺纹,是通过替换保护网格以安装鼻锥。

More details

The design of G.R.A.S nosecones is based on requirements from the National Aeronautical Laboratory of the Netherlands (NLR), who investigated the classical sharp-tipped nosecone and concluded that with this design, the stagnation point is unpredictable i.e. the turbulence could emerge at any point on the surface and cause unwanted pressure variations, which could reach the diaphragm.

GRAS鼻锥的设计是基于荷兰国家航空实验室(NLR)的需求设计的,他们研究了经典的尖头鼻锥,并得出结论。通过这种设计,即湍流可能在任何一点,出现停滞点是不可预测的,。 換句話說,表面并引起不必要的压力变化,这也可能接触到麦克风隔膜。

G.R.A.S

A new design with a blunt tip was developed. This forces a predictable stagnation point already at the tip. As this turned out to be a success and a great improvement compared to the classical design with a sharp tip, this is now specified in the NLR requirement TP 96320. The surface is high-gloss polished to further improve the aerodynamic performance.
