WK1: 5 Components of an Aircraft Flashcards
What is a fuselage?
(1) Fuselage is the connecting point of all the other components of an aircraft.
(2) Houses the cabin, and/or cockpit which contains the seat of the occupants, and the controls.
(3) Is the main body of an aircraft.
What are the 4 parts of a fuselage?
- Bulkhead
- Stringers
- Formers
- Skin
Enumerate the two structures of a fuselage.
- Open truss structure.
2. Skin stressed structure.
A type of a fuselage structure that can be identified through clearly visible struts and wire-braced wing.
Open truss structure
What are the different types of a skin stressed structure? Define each.
- Monocoque: Carries all the parts or major parts of the stresses.
- Semi-monocoque: Has a sub structure that maintains the shape of the airframe and increases its strength.
Define the bulkhead.
- It separates a section of an aircraft.
- Provides shape for the fuselage.
What is the function of a former?
Provides shape for the fuselage.
What is the purpose of the skin?
- To cover the integral parts.
- Must be strong enough to keep the fuselage rigid.
Explain an aircraft wings.
(1) Where the fuel tanks are located.
(2) Generates a force called lift when air surrounds the wings.
(3) Are airfoils that is located in each side of the fuselage, and is the main lifting surfaces that supports an aircraft in flight.
What is a lift?
A type of force that is generate when air surrounds the wings.
What are the different classification of wings?
- High wing
- Low wing
- Mid wing
Enumerate the 2 types of wings.
- Monoplane
2. Biplane
What are the wing support designs? Describe each.
- Cantilever design: A self-supporting wing.
2. Braced type: Are braces that helps support the wings.
What are the 2 sub-types of braced type wings? Describe each.
- Strut braced (Semi-cantilever): Has one or more stiff struts to support the wings.
- Wire braced: Commonly used in biplanes.
Define the empennage.
It consists of the vertical stabilizer (fin) and the horizontal stabilizer.
What are the 5 parts of an empennage?
- Horizontal stabilizer
- Vertical stabilizer
- Elevator
- Trim tabs
- Rudder
What is a rudder?
It can be used for moving the nose of an aircraft up and down.
What is an elevator?
Responsible for the pitching movement of an aircraft.
What is a trim tabs?
It aerodynamically minimizes the workload.
The principal support of an aircraft when parking, taxiing, taking off, and landing.
Landing gear
State the 4 types of landing gear.
- Tricycle landing gear
- Conventional landing gear
- Tandem landing gear
- Amphibious landing gear
Enumerate and define the 2 classifications of a landing gear.
- Retractable landing gear: Used by high-performing aircrafts.
- Fixed landing gear: Less expensive.
What are the parts of a landing gear?
- Oleo strut
- Brakes
- Torque link
- Shimmy dumper
________ is the hinge between the piston and the cylinder. It also allows the piston to move freely in & out the landing gear but prevents it to rotate.
Torque link
It minimizes the vibrations due to engine output.
Shimmy dumper
Define an oleo strut.
Uses a piston enclosed in a cylinder.
Typical training aircraft uses disc brake that is located in the ______.
(Provide 2 answers)
- Brakes
2. Main wheels
In small airplanes, the (1)________ includes both the (2)______ and the (3)_______.
- Powerplant
- Engine
- Propeller
It provides the power to turn the propeller.
Powerplant
What are the 4 parts of a powerplant?
- Firewall
- Engine
- Propeller
- Cowling
What are the 5 major components of an aircraft? And where does it belong?
- Fuselage: In the center
- Wings: Both sides of the fuselage
- Empennage: At the back of an aircraft
- Landing gear: Beneath the fuselage
- Powerplant: In front of the aircraft
Move in opposite directions to create aerodynamic forces that cause an aircraft to turn.
Ailerons
What is a flap?
It increases the lifting force of the wing for take offs and landing.
