The MQ-4C is powered by this:
Rolls-Royce AE3007H engine
The MQ-4C is capable of using these four fuel types:
JP-5, JP-8, JP-8+100, TS-1
This is the altitude at which the EO/IR turret is pressurized.
25,000 feet
This law states the pressure exerted anywhere upon an enclosed liquid is transmitted undiminished, in all directions, to the interior of the container.
Pascal's Law
The area is defined by lines connecting the aircraft’s nose, wingtips, and aft of the tail.
Safety diamond
A two-stage turbine. It changes the energy of the hot gases into a mechanical energy. The HPT uses this mechanical energy to turn the compressor and the accessory drive.
A three-stage turbine that converts energy from the gas flow to power the fan rotor via the inner spool. Air exiting the Low Pressure Turbine mixes with the bypass air and provides thrust.
High Pressure Turbine (HPT)
Low Pressure Turbine (LPT)
How many fuel tanks are in the MQ-4C, what is the total capacity in gallons?
Eight fuel tanks totaling 2,518 gallons.
This type of coolant is circulated through a closed loop system through cold plates.
Polyalphaolefin (PAO)
The MQ-4C uses 4.75 gallons of this Hyd fluid.
MIL-PRF-87257 at 3000 psig
The primary flight control system moves the airplane about three axes, lateral, longitudinal, and vertical. The primary flight control system has these components:
Ailerons, Ruddervators, and Spoilers
Hydraulic pump, Lube and scavenge pump, Fuel pump metering unit (FPMU), Air turbine starter, Permanent magnet alternator (PMA), DC Generator, and 30KVA AC Generator belong to what system?
Accessory Drive Gearbox
The system also circulates fuel through this system for payload equipment temperature control.
ECS
These systems are cooled by PAO coolant.
SATCOM High Power Amplifier/High Voltage Power Supply (HPA/HVPS), Wide-band Receiver Exciter (WBRE), Multi-Function Active Sensor (MFAS) Radar Antenna
The Emergency Blowdown Bottle is pressurized to this amount using what gas?
3000 psi of Nitrogen
This action changes the angle of attack eliminating the need for conventional wing flaps. This function increases the initial lift created by wing.
NLG Hiking
Engine Oil Pressure, Temperature and Level, Engine Fan and Turbine vibrations are parameters sent by IMMC to form this system.
Engine Indicating System (EIS)
What is the largest fuel tank on the MQ-4C?
Wing Root Tank (1285 gal)
Air is used to pressurize fuel tanks when the aircraft climbs above this altitude to prevent fuel cavitation.
46,000 feet
The following components are a part of what system?
Hydraulic Reservoir Temperature Transducer, Pump Discharge Pressure Transducer, Hydraulic Fluid Level Indicator, Hydraulic Fluid level Sensor
Hydraulic Indicating System
Responsible for sending flight control surface commands to all control surface actuators, amongst other functions. Is equipped with two channels A and B for redundancy
Integrated Mission Management Computer (IMMC)
This provides sensor and control data to and from the IMMC Continuous Signal Comparer. Sensors include fan and compressor corrected speeds, Power Lever Angle, Inter-stage Turbine Temperature, and Compressor Inlet Temperature.
Full Authority Digital Electronic Controls (FADEC)
This component monitors pressure, fuel quantity remaining, fuel temperature, avionics compartments’ temperature, fuel float switch positions, fuel probe levels, and fuel quantity remaining
IMMC
The Environmental Control System (ECS) uses these to maintain suitable operating environments
Aircraft fuel, bleed air, and ram air
Ground maintenance personnel can apply this to pressurize the air vehicle system to 3,000 psig at 15 GPM.
