Eating right with Alejandra
What will happen if you put jet fuel in a reciprocating engine?
It will several damage or ruin the engine.
Name the major components in a gas turbine engine
Air inlet, compressor section, combustion section, turbine section, exhaust section, gearbox, and accessory section.
The stress that produces twisting
Torsion
Four factors of flight
Life, weight, thrust, and drag
How many days do you have to notify the FAA of an address change?
30 Days
What is the color of jet fuel?
Clear or straw colored.
What determines the amount of airflow through a turbine engine?
The forward speed of the aircraft, compressor speed, and air density.
THE STRESS THAT RESISTS A CRUSHING FORCE
COMPRESSION
What advantages do lowering flaps give you?
Decreased stall, increased life, and increased drag.
What FAR covers mechanics?
Part 65, subpart D.
What type of oil is used for reciprocating engine break-in?
Straight mineral oil
Name the two types of compressors commonly used in turbine engines.
Axial and centrifugal flow compressors.
STRESS THAT RESISTS A FORCE THAT TENDS TO PULL SOMETHING APART.
TENSION
In order to remain airworthy, what is the minimum inspection required?
An annual inspection.
What regulation defines a major or minor repair?
Part 43, Appendix A
What is the color of the main fuel used in reciprocating engines?
100LL is blue
Name two different methods for attaching turbine engine rotor blades to the rotor disks.
-Dovetail-type root -or- Bulb-type root -or- Fir tree-type root
THE STRESS THAT RESISTS THE FORCE TENDING TO CAUSE ONE LAYER OF A MATERIAL TO SLIDE OVER AN ADJACENT LAYER.
Shear
What is the term that describes the angle between the relative wind and the chord line of an airfoil
Angle of Attack
A certificated mechanic may not exercise the privileges of his certificate and rating unless, within the preceding 24 months
He has, for at least 6 months—
(1) Served as a mechanic under his certificate and rating;
(2) Technically supervised other mechanics;
(3) Supervised, in an executive capacity, the maintenance or alteration of aircraft; or
(4) Been engaged in any combination
What are some of the possible outcomes of using a lower grade of avgas than the specified grade
Detonation, loss of power, and increased likelihood of overheating.
What is a split compressor system?
Also called dual or twin spool compressors, these are connected to the turbine section with two rotor shafts, one inside the other.
STRESS IS A COMBINATION OF COMPRESSION AND TENSION
Bending
What is the function of a wing mounted vortex generator
Vortex generators delay or keep the airflow from separating from the upper surface of a wing during high speed flight
What part of the FARs describes the performance characteristics that a small aircraft must demonstrate in order to be airworthy?
Part 23
Describe the important precautions that should be observed when fueling an aircraft.
Correct fuel, properly ground the aircraft and refueling unit, and protect surfaces from hose and nozzle damage.
What are the different types of combustion chambers used in turbine engines?
Can, annular, can-annular, and reverse flow annular.
What is the grip length of a bolt?
The length of the unthreaded portion.
How does blade-flapping help to compensate for dissymmetry of lift in helicopter main rotor systems?
Flapping increases the angle of attack and lift on the retreating blade and decreases the angle of attack and lift on the advancing blade.
How does the FAA notify aircraft owners of unsafe conditions that must be corrected?
By issuing Airworthiness Directives
