Wings are designed for specific airflow, based on the airplane’s purpose. Most airplanes have an asymmetrical design. This design allows Bernoulli’s Principle – the movement of a fluid through a pressure difference – to take effect and produce lift by creating a relatively low pressure above...
Airplanes are equipped with sensors that gather data such as acceleration, airspeed, altitude, flap settings, outside temperature, engine performance, and cabin temperature and pressure. Magnetic-tape recorders can track about 100 parameters, while solid-state recorders can track a lot more. For inst...
While many of the same design, aerodynamic and piloting factors that apply to powered airplanes also apply to gliders, that lack of a motor changes a lot about how gliders work. Gliders are amazing and graceful machines, and are about as close as humans can get to soaring like birds. If ...
When shipping internationally, your document or parcel travels within the DHL Express network, transiting through multiple facilities, people, vehicles and airplanes. A well-packed shipment can reduce the risks of damage, ensuring your consignee receives the contents in pristine condition...
As forces are applied to the axle, the two points identified will attempt to move in the indicated directions. Why does a gyroscope display this behavior? It seems totally nonsensical that the bicycle wheel's axle can hang in the air like that. ...
The trainees want to be among the Air Force’s elite Special Warfare troops, those who leap from airplanes on rescue missions or embed with front-line troops to direct air strikes. But before they can do that, they face a gantlet of unforgiving qualification courses with infamously high wash...
Phobic stressors are those caused by situations you are extremely afraid of, such as flying in airplanes or being in tight spaces. Physical stressors are situations that overtax your body, such as working long hours withoutsleep, depriving yourself of healthy food, or standing on your feet all...
One common cause of fear is a lack of knowledge or understanding. For example, if you are afraid of flying, learning more about airplanes and how they work can help alleviate your fears. Another cause of fear is past trauma or negative experiences. In these cases, it may be ...
due to the way air circulates and is filtered on airplanes, “most viruses and other germs do not spread easily,” but that travelers are still advised to “avoid contact with sick passengers and wash their hands often with soap and water for at least 20 seconds or use hand sanitizer that...
This echoes the official advice from the Centers for Disease Control and Prevention that, due to the way air circulates and is filtered on airplanes, “most viruses and other germs do not spread easily,” but that travelers are still advised to “avoid contact with sick passengers and wash ...
