Welcome to Southern Sydney Angiography We are proud to introduce Southern Sydney Angiography, a state of the art interventional radiology unit! Southern Sydney Angiography is an Interventional Radiology Service that operates in the St George Private Hospital.
During takeoff and landing, the flaps on the back of the wing extend downward from the trailing edge effectively altering the shape of the wing. This change enables it to divert more air generating more lift. This change also increases drag, which helps a landing airplane slow down while requiring more thrust during takeoff.
Transcript of Describe the Types of Drag That Act Upon an Aircraft Why? - to take a closer look at one of the four forces that act upon an aircraft/principles of flight MTP 1: What is drag? - The Force that opposes foreword motion of an aircraft. MTP 2: What is Parasite Drag? - The drag created by parts of the aircraft that do not create lift Form Drag The drag created by the body of the aircraft as it resists air MTP 3: Wing Tip Vortexes Phenomenon called Wing Tip Vortexes are evidence that induced drag indeed does exist.
