Biomechanics: Wind tunnels

Question 1

Wind tunnel

Answer 1

A chamber through which air is forced

Question 2

How wind tunnels work?

Answer 2

Object/performer tested is placed in the tunnel.
A controlled flow of air is forced through.
Airflow around the object studied to measure resistance around it.

Question 3

Benefits of wind tunnels

Answer 3

• Equipment & technique can be abated to increase the aerodynamic properties (reduce the effect of air resistance & increase performance)
• Wind speed & direction are controllable to mimic competitive conditions
• Individual pieces of equipment can be tested

Question 4

Disadvantages of wind tunnels

Answer 4

• Equipment is expensive & usually located in engineering facilities/research labs
• Real life conditions may impact unexpectedly so results not always realistic
