TRURBINE ENGINE QUIZ Flashcards
A TUBINE ENGINE USUALLY HAS A ACCESSORY SECTION GEAR TRAIN GIVEN BY ?
THE ENGINE HIGH PRESSURE COMPRESSOR THROUGH AN ACCESSORY DIRIVE SHAFT GEAR COUPLING.
THE BASIC ELEMENTS OF THE ACCESSORY SECTION OF A TUBOFAN ENGINE ARE?
THE ACCESSORY GEARBOX, WHICH HAS MACHINED MOUNTING PADS FOR THE ENGINE DRIVEN ACCESSORIES, AND THE GEAR TRAIN, WHICH IS HOUSED INSIDE THE ACCESSORY CASE
WHAT IS THE PRIMARY FUNCTION OF THE ACCESSORY SECTION OF A TURBINE ENGINE?
IT PROVIDES SPACE FOR THE MOUNTING OF ACCESSORIES NECESSARY FOR OPERATION AND CONTROL OF THE ENGINE.
THE REDUCTION GEARING WITHIN THE ACCESSORY SECTION CASING PROVIDES SUITABLE DRIVE SPEED FOR ?
EACH INGINE ACCESSORY OR COMPONENT.
REDUCTION GEAR RATIOS WITHIN THE ACCESSORY SECTION ARE RELATIVELY HIGH BECAUSE ?
THE ROTOR OPERATING RPM IS SO HGH
IN A GAS TURBINE ENGINE THE INLET, COMPRESSOR, AND DIFFUSER SECTIONS ARE RESPONSIBLE FOR?
BUILDING POTENTIAL ENERGY OF THE AIRFLOW
WHAT IS A PRIMARY DESIGN LIMITATION OF A TURBOJET ENGINES?
TURBINE INLET TEMP.
DESCRIBE THE PURPOSE OF THE TUBINE SECTION OF A TURBOJET ENGINE
TURN THE COMPRESSOR
WHICH ENGINE COMPONENTS WOULD BE MOST DAMAGED BY EXCESSIVE EGT?
TUBINE BLADES
UNDER NORMAL OPERATING CONDITIONS, WHAT POINT IN A JET ENGINE HAS THE HIGHEST STATIC PRESSURE?
THE COMBUSTION CHAMBER INLET
UNDER NORMAL OPERATING CONDITIONS, WHAT POINT IN A JET ENGINE HAS THE HIGHEST TEMPERATURE?
THE TURBINE SECTION INLET
WHAT EFFECT IN ANY DOES HIGH AMBIENT TEMPERATURE HAVE UPON THE THRUST OF TURBINE ENGINE?
THE THRUST WILL BE REDUCED DUE TO THE DECREASE IN AIR DENSITY
WICH ENGINE INSTRUMENT WILL BEST INDICATE ANGINE DAMAGE?
N2
ENGINE PRESSURE RATION IS DETERMINED BY
DIVIDING TURBINE OUTLET TOTAL PRESSURE BY ENGINE INLET TOTAL PRESSURE
WHICH OF THES ITEMS WOULD NOT NORMALLY BE FITTED TO THE ENGINE ACCESSORY SYSTEM
NOT NORMALLY
EGT/TIT
WHICH OF THESE IS THE BEST INDICATION THAT THE ENGINE HAS SEIZED IN FLIGHT?
OIL PRESSURE
THE PROCESS OF TAKING HIGH VELOCITY, LOW PRESSURE AIR, AND TURNING IT INTO LOW VELOCITY, HIGH PRESSURE AIR IS THE PRIMARY FUNCTION OF THE ?
DIFFUSER
DESCRIBE THE PURPOSE OF THE COMPRESSOR SECTION OF A TURBOJET ENGINE.
INCREASE THE PRESSURE OF THE AIR FLOWING THROUGH THE ENGINE.
WHERE IS THE HIGHEST PRESSURE IN A GAS TURBINE ?
COMPRESSOR DISCHARGE
THE SECTION OF THE ENGINE WHICH INCREASES THE ENERGY OF THE AIR RECEIVED FROM THE ENTRANCE DUCT, THEN DISCHARGES INTO THE DIFFUSER SECTION AND THE COMBUSTION CHAMBER IS CALLED
COMPRESSOR
PRIMARY FUNCTION OF THE TURBINE SECTION IN A TURBINE ENGINE IS TO
DRIVE THE COMPRESSORS THROU COMMON SHAFTS
IN THE COMBUSTION/BURNER SECTION OF AN ENGINE , PRIMARY AIR IS USED FOR WHAT PURPOSE?
MIXING WITH FUEL PRIOR TO COMBUSTION
IN WHAT FLIGHT REMINE WOULD YOU MOST LIKELY ENCOUNTER A COMPRESSOR STALL?
T/O WITH STRONG CROSSWIND
THE PRIMARY FUNCTION OF THE COMPRESSOR SECTION IN A GAS TURBINE ENGIE IS
PROGRESSIVELY SQUEE=ZE AIR IN PREPERATION FOR COMBUSTION
