Experiment on Engineering

The experiment conducted was the small
wind tunnel lift and drag experiment. In this experiment, the drag and lift
coefficient were recorded as part of our data collection. It is important to
note that a small wing was used in part of the experiment conducted. In the
experiment, the angles were changed within each recorded data set. After
testing different angles, a stall angle was determined to be 12 degrees. In
confirming the stall angle, extra data was recorded to ensure the value was
correct. Angles were taken at increments of 2 degrees. The readings complied
with the main goal of achieving a stalling angle.

The purpose of this experiment was to
measure the lift and drag of a wing. A small wind tunnel with a wing was
utilized to gather lift and drag coefficients. Thus, there are several factors
that are dependent on the wing’s position/angle. There will be different
affects at different angles. This can be applicable to many objects in modern
day such as aircrafts or UAVs. Lift is a big factor in making an aircraft take
off or land. Drag creates a downforce that will push an object down. The three
variables of cross section, air speed and angle of attack are vital in the
application of lift and drag. The experiment conducted was applicable with a
small wing. The angle of the angle was able to changed from a negative to
positive coordinate of degrees to observe stalling angle. As the angle
increases, the lift begins to decrease and stalling will be achieved.
