The space agency has decided to remove foam from that area of the tank and has conducted aerodynamic tests to make sure it can be done without additional risk.

In fact, basic aerodynamic tests are sometimes performed underwater.

From the various aerodynamic tests on the seven different airframes, one airframe in particular the J-13V was later incorporated into the further development of Chengdu's J-10 project.

This was his second time driving Formula One machinery following a straight-line aerodynamic test for the team earlier in the year.

However aerodynamic tests on models of the bridge showed that, while the bridge itself would be stable, the presence of the adjacent railway bridge would cause severe oscillation.

At first, simulation was limited to pilots practicing night landings or aerodynamic tests in wind tunnels.

Air also moves like water does - in fact, some aerodynamic tests take place underwater instead of in the air.

Dr. Hollenberg has tested only a small sample, and aerodynamic tests have not been performed elsewhere.

Because the car had to have a very low drag coefficient, aerodynamic tests were part of the early evaluations.

These systems are normally tested by a truck based aerodynamic test.
