TESTE DEIN WISSEN

What is an airfoil?

Lösung anzeigen
TESTE DEIN WISSEN

wing with infinite wingspan (2D)


to investigate aerodynamic characteristics -> look at airfoils cross section; no 3D-effects

TESTE DEIN WISSEN

How is Lift generated (surface forces)?

Lösung anzeigen
TESTE DEIN WISSEN

A body generates high amount of lift by ascelerating the flow on the upper side; decelerating the flow on the lower side

When came the Wright Flyer & what was special about it?

Lösung anzeigen
TESTE DEIN WISSEN

1905

-the first biplane motorized plane 

-controlled by a pilot

TESTE DEIN WISSEN

What are the functions of the wings? primary &secondary

Lösung anzeigen
TESTE DEIN WISSEN
Primary Functions:

- Generation of lift

- Attachment of control surfaces


Secondary Function:

- Storage of fuel/cargo

- Attachment of: landing gear, powerplants, mission equipment

TESTE DEIN WISSEN

What is the Sweep angle?

Lösung anzeigen
TESTE DEIN WISSEN
higher sweep angle helps reduce drag at high Mach velocities, essential for efficient cruise flight at high speed

TESTE DEIN WISSEN

When came Junkers D.I  & what was special about it? 

Lösung anzeigen
TESTE DEIN WISSEN

1918

- all-metal aircraft -> stable for weather conditions


-> light metal aluminium into aircraft construction 


Lösung ausblenden
TESTE DEIN WISSEN

What is the Aspect Ratio?

Lösung anzeigen
TESTE DEIN WISSEN

a measurement of the slenderness of the wing AR=(b^2)/2


higher aspect ratio reduces the lift dependent drag thus increasing aerodynamic efficiency of a wing

usually 4-50

high AR only gliders

When came Sopwith Camel & what was special about it?

Lösung anzeigen
TESTE DEIN WISSEN

1916

- a biplane and is considered the most successful British fighter of the First World War -> fast developement in the first 20 years of aviation

TESTE DEIN WISSEN

Which Flaps do you know? And what are they for?

Lösung anzeigen
TESTE DEIN WISSEN

(Trailing edge) flaps 

&

(Leading edge) flaps 


they are leading to a higher lift at lower flight speeds
