Exchange on the construction of jet wind tunnel

Overall idea and process of system composition (to be constructed)

With the deepening of research, in order to meet the testing needs of fixed wing and rotary wing unmanned aerial vehicle development and related environmental impact characteristics, a "unified planning wind tunnel" is proposed.

1) 6-meter x 3-meter jet wind tunnel, wind speed of 5m/s-60m/s, blowing angle ± 30;

3) 5.5m x 2.5m reflux wind tunnel, wind speed 3m/s-55m/s, blowing angle ± 30; Consider both temperature and humidity changes simultaneously.

With the deepening of research, in order to meet the testing needs of fixed wing and rotary wing unmanned aerial vehicle development and related environmental impact characteristics, a "unified planning wind tunnel" is proposed.

4) Three parallel jet wind tunnels with wind speeds ranging from 5m/s to 50m/s and blowing angles of ± 30 degrees;

With the deepening of research, in order to meet the testing needs of fixed wing and rotary wing unmanned aerial vehicle development and related environmental impact characteristics, a "unified planning wind tunnel" is proposed.

5) Two parallel jet wind tunnels, one direct flow jet and one backflow jet.

After sufficient technical exchanges with the project team and comprehensive evaluation, only two parallel jet wind tunnels (one small and one large) are currently being considered for construction.
