Drag The force that resists forward motion and acts against thrust. Two types are: Parasite Drag Induced Drag

Drag Parasite drag is comprised of all the forces that work to slow an aircraft’s movement. Drag that is not associated with the production of lift. This includes the displacement of the air by the aircraft, turbulence generated in the airstream, or a hindrance of air moving over the surface of the aircraft and airfoil. There are three types of parasite drag: form drag, interference drag, and skin friction.

Define Interference drag. The type of drag refers to a change in the physical shape of the boundary layer which causes a dramatic decrease in lift and an increase in drag. What is it?

Form Drag Form drag is the portion of parasite drag generated by the aircraft due to its shape and airflow around it. Examples include the engine cowlings, antennas, and the aerodynamic shape of other components.

Define Interference drag. The type of drag refers to a change in the physical shape of the boundary layer which causes a dramatic decrease in lift and an increase in drag. What is it?

Interference Drag Interference drag comes from the intersection of airstreams that creates eddy currents, turbulence, or restricts smooth airflow. For example, the intersection of the wing and the fuselage at the wing root has significant interference drag.

Define Interference drag. The type of drag refers to a change in the physical shape of the boundary layer which causes a dramatic decrease in lift and an increase in drag. What is it?

Skin Friction Drag This change in the physical shape of the boundary layer causes a dramatic decrease in lift and an increase in drag. When this happens, the airfoil has stalled.

THIS DAY IN AVIATION September 11 1920 — Edison Mouton flies into Marina Field, San Francisco, to complete the first US transcontinental airmail flight. Having left from New York, it took Mouton and his crew over 75 hours to complete the feat.

THIS DAY IN AVIATION September 11 1929 — The Fokker F-32 four-engined luxury airliner makes its first US flight at Teterboro Airport.

THIS DAY IN AVIATION September 11 2001 — The September 11 attacks (called September 11, September 11th or 9/11), were a series of four coordinated suicide attacks by al-Qaeda on the United States on Tuesday, September 11, 2001.

THIS DAY IN AVIATION September 11 On that morning, 19 al-Qaeda terrorists hijacked four passenger jets. The hijackers intentionally crashed two planes into the Twin Towers of the World Trade Center in New York City, killing everyone on board and thousands of those working in the buildings. Both towers collapsed within two hours, destroying nearby buildings and damaging others. A third plane was crashed into the Pentagon in Arlington, Virginia.

THIS DAY IN AVIATION September 11 Hijackers had redirected the fourth plane toward Washington, D.C., targeting either the Capitol Building or the White House, but crashed it in a field near Shanksville, Pennsylvania after passengers tried to take control of the plane. There were no survivors from any of the flights.

THIS DAY IN AVIATION September 11 Nearly 3,000 victims and the 19 hijackers died in the attacks. Among the 2,753 victims who died in the attacks on the World Trade Center were 343 Firefighters and 60 police officers from New York City and the Port Authority, and 8 private emergency medical technicians and paramedics. Another 184 people were killed in the attack on the Pentagon. The overwhelming majority of casualties were civilians, including nationals of over 70 countries.

THIS DAY IN AVIATION September 11 Suspicion quickly fell on al-Qaeda. Its leader Osama bin Laden initially denied involvement, but in 2004 he finally claimed responsibility for the attacks. Al-Qaeda and bin Laden cited United States support of Israel, the presence of United States troops in Saudi Arabia, and sanctions against Iraq as motives for the attacks. The United States responded to the attacks by launching the War on Terror, invading Afghanistan to depose the Taliban, who had harbored al-Qaeda members.

THIS DAY IN AVIATION September 11 It was not until May 2011 that bin Laden was found and killed. Many countries strengthened their anti- terrorism legislation and expanded law enforcement powers. Some American stock exchanges stayed closed for the rest of the week following the attack and posted enormous losses on reopening, especially in the airline and insurance industries. The destruction of billions of dollars' worth of office space caused serious damage to the economy of Lower Manhattan.

THIS DAY IN AVIATION September 11 The damage to the Pentagon was cleared and repaired within a year, and the Pentagon Memorial was built adjacent to the building. Rebuilding at the World Trade Center site began in 2002. Ground was broken for the Flight 93 National Memorial on November 8, 2009, and the memorial was formally dedicated on September 10, 2011.
