The quality evaluation of aero-thermal flowfield in 0.75m × 0.50m icing wind tunnel

Hangkong gongcheng jinzhan
The quality of aero-thermal flowfield of the icing wind tunnel is the precondition for its experimental application. In order to evaluate the quality of the aerodynamic flowfield and the thermodynamic flowfield of 0.75 m × 0.50 m icing wind tunnel, the ...

New Transonic Tests of HB-2 Hypersonic Standard Models in the VTI T-38 Trisonic Wind Tunnel

Aerospace
Recent experience has shown that test results of standard wind tunnel models under off-design conditions could be a useful aid in preparations of some nonstandard wind tunnel tests.

Prediction of Wind Velocity to Raise Vortex-Induced Vibration through a Road-Rail Bridge with Truss-Shaped Girder

Shock and Vibration, 2018
Vortex-induced vibration (VIV) of bridges, related to fluid-structure interaction and maintenance of bridge monitoring system, causes fatigue and serviceability problems due to aerodynamic instability at low wind velocity.

WIND TUNNEL TEST FOR MEMBRANE STRUCTURE

Wind Engineers, JAWE, 1999
Membrane structures are very light weight structure and those deflection at strong wind are very large, frequently. Therefore, wind tunnel tests has been planned to investigate aerodynamic behavior. The model for test requir that many similarity parameters are matched for model and prototype. In practice, it is almost impossible to match all similarity

The Design of Autonomous UAV Prototypes for Inspecting Tunnel Construction Environment [PDF]

arXiv
This article presents novel designs of autonomous UAV prototypes specifically developed for inspecting GPS-denied tunnel construction environments with dynamic human and robotic presence. Our UAVs integrate advanced sensor suites and robust motion planning algorithms to autonomously navigate and explore these complex environments.
