Random 1 Flashcards
What are the forces that affect flight?
Lift
Drag
Weight
Thrust
What is an aerofoil?
The cross sectional shape of a wing or blade.
What is Newton’s third law?
To every action there is an equal and opposite reaction.
When a system expels or accelerates mass in one direction, the accelerated mass will cause a force of equal magnitude but opposite direction on that system.
What is the difference between air pressure and air density?
Air pressure: is determined by the number of air molecules above a surface. More molecules = more pressure and vice versa.
Name the basic components of an aero plane.
Fuselage
Wings
Empennage
Landing gear
Powerplant
Where are the slats located?
On the leading edge of the wing.
What are geometrical features of the wing?
Wing span
Wing area
Wing chord
Wing section
Dihedral angle
Sweep back
What are the main types of aircraft?
- Fixed wing
- Rotary aircraft
Define lift.
The force generated to overcome weight which makes an aircraft fly. This force is obtained by the motion of the aircraft through the air.
How are aircraft engine position numbered?
Left to right from the view of the pilot looking forward.
What are the parts of an aircraft empennage?
Horizontal stabilizer
Elevators
Trims
Vertical stabilizer
Rudder
Name the parts of an aero plane wing.
Flaps
Aileron
Winglets
Spoilers
Slats
A Dihedral angle is the upward angle of an aircraft’s wing from the wing root to the wing tip. True or False.
True.
What is the purpose of the winglet?
To reduce drag (air resistance) as the aircraft pushes through the air.
What are the main components of a helicopter?
The airframe
The fuselage
The landing gear
The power plant (engine)
The main rotor system
The tail rotor system
