Wirbelschleppen Flashcards

Q

Wirbelschleppen:

A
  • Gefährlich für nachfolgende Flugzeuge
  • Separation durch Distanz (Radar) oder Zeit
  • Separation Minima:
    — Distance
    — Arrival - Arrival
    — Departure - Departure (Same Intersection)
    — Departure - Departure (different Intersection)
    — Departure hinter Arrival
    — Arrival hinter Departure

Q

Wie entstehen Wirbelschleppen?

A
  • Durch Auftrieb
  • Druckunterschiede zwischen Ober und Unterseite
  • wandert über Flügelspitzen
  • erzeugt rotierende Bewegungen
  • Gefahr für leichtere Flugzeuge dahinter

Q

Wie können Wirbelschleppen vermieden werden?

A
  • Winglets, Wingtip Tank, Sharklets, Scimitar Winglets
  • Wing Taper (Fläche nach außen schmaler)
  • high Aspect Ratio (breitere Flügel)
  • Reduction of incidence (Flügel nach hinten schmaler)
