Newton’s Law of Gravitation is universal. Airplanes aren’t any exception. They need to act against this law to lift off and fly. And, you need to have exemplary knowledge of Aerodynamics to make them not just fly, but also to take-off and land, to maneuver, to climb, to turn, roll, pitch and yaw to your satisfaction.
Don’t let gravity pull your score of this Airplane Aerodynamics Quiz down!
Which force does NOT act on an aircraft in steady and level flight?
In steady and level flight, the four forces are thrust, drag, lift and weight.
It's the angle between the wing chord and the wind direction
The aircraft 'attacks' the wind at this angle!
In steady and level flight, the sum of forces is zero. The aircraft still moves forward. What is it?
The aircraft is stable in its motion - Dynamic Stability
Retracting landing gears nearing the airframe produce
Interference drag is produced by the mixing of two air streams around two different aircraft surfaces.
Which force makes an aircraft turn?
The Vertical Component of Lift
The Horizontal Component of Lift
Centrifugal Force
The Turn-side Component of Lift
For a aircraft in turn, vertical lift opposes gravity and horizontal lift which opposes inertia. It is the horizontal lift component that assists the aircraft in turning
This type of flow is practically impossible over the aircraft
Inviscid flow only exists in assumptions
Shocks are feature of what type of flow
Shocks is a feature of flow over Mach 1 (Supersonic flow )
It's the Mach Number
Speed of Sound by Speed of Aircraft
Speed of Aircraft by Speed of Sound
Speed of Aircraft by Speed of Light
Speed of Sound by Speed of Light
By definition of the Mach Number ...
It's the Reynolds Number
Viscous force by inertia force
Inertia force by viscous force
Pressure force by inertia force
Inertia force by gravity force
By the very definition of Reynolds number...
