Product Description

Product Description

Application scope: 
The Air velocity standard device is suitable for the study of aerodynamic performance of aerospace vehicles, especially the study of performance during takeoff and landing. In addition, it is also used to study the fluid dynamic performance of underwater weapons and the aerodynamic characteristics of aerospace life-saving equipment, as well as the aerodynamic performance of cars and trains. The research scope of the DC low-speed wind tunnel also includes the aerodynamic characteristics of wind power machinery, the stress state of single or group building structures in the wind field and their response characteristics to wind loads, as well as the wind load state and wind vibration laws of bridges. These studies are not only crucial to aerospace engineering, but also play an indispensable role in transportation, housing construction, wind energy utilization and other fields.

 

Features
