Following the end of World War II, Dr. Sighard F. Hoerner was a pioneer researcher in the field, having written a technical paper published in 1952 [7] that called for drooped wingtips whose pointed rear tips focused the resulting wingtip vortex away from the upper wing surface. Drooped wingtips are often called "Hoerner tips" in his honor.
A wing tip (or wingtip) is the part of the wing that is most distant from the fuselage of a fixed-wing aircraft. Because the wing tip shape influences the size and drag of the wingtip vortices, tip design has produced a diversity of shapes, including: Squared-off; Aluminium tube bow; Rounded; Hoerner style; Winglets; Drooped tips; Raked ...
Sighard F. Hoerner (18 April 1906, in Münster, Germany – 22 June 1971, in Brick Town, USA) [1] was a German scientist. An important figure in the aerodynamics field, he is known for his two compendiums of aerodynamic knowledge, Fluid-Dynamic Drag and Fluid-Dynamic Lift .
The Ranger differed from the AL-60 in having main landing gear leg fairings and Hoerner wing tips. [1] [2] [3] The Ranger's wing employed large flaps. Approved floats were Edo Aircraft Corporation models and both straight skis and Genaire Limited Canada Fluidyne Engineering wheel skis could also be fitted. Cabin access was through the small ...
The never-before-seen technology has several advantages, but the idea stemmed from airport-gate space limitations and the 777X's huge wingspan.
The boy would tip them off to IEDs and occasionally brought them fresh-baked bread. One day, as Martz’s platoon walked a routine patrol, the boy yanked a trigger wire from a hidden position. Whether he had been a secret enemy all along or whether some incident had turned him against the Americans are questions Martz wrestles with to this day.
How To Make My 3-Ingredient Smoked Salmon Dip. For 2 1/2 cups, or 6 to 8 servings, you’ll need: 8 ounces cream cheese, room temperature 4 to 6 ounces hot smoked salmon, flaked
Wing tips Wing tips are often formed as complex shapes to reduce vortex generation and so also drag, especially at low speed. [11] Wheels on fixed gear aircraft Wheel fairings are often called "wheel pants", "speed fairings" in North America or "wheel spats" or "trousers", in the United Kingdom, the latter enclosing both the wheel and landing ...
