What are the primary flight controls for? How are they called?
to ensure maneuverability and controllability of the aircraft
aileron, rudder, elevator
When came Junkers Ju 52 & what was special about it?
1932
- diesel engine -> proper aircraft
- 3 engines
- cantilver wings & corrugated aluminium sheet metal
When came Airbus A320 & what was special about it?
1987
-digital fly-by-wire system -> safer
What is an airfoil?
wing with infinite wingspan (2D)
to investigate aerodynamic characteristics -> look at airfoils cross section; no 3D-effects
How is Lift generated (surface forces)?
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?
1905
-the first biplane motorized plane
-controlled by a pilot
What are the functions of the wings? primary &secondary
- Generation of lift
- Attachment of control surfaces
Secondary Function:
- Storage of fuel/cargo
- Attachment of: landing gear, powerplants, mission equipment
What is the Sweep angle?
When came Junkers D.I & what was special about it?
1918
- all-metal aircraft -> stable for weather conditions
-> light metal aluminium into aircraft construction
What is the Aspect Ratio?
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?
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
Which Flaps do you know? And what are they for?
(Trailing edge) flaps
&
(Leading edge) flaps
they are leading to a higher lift at lower flight speeds
