Set B Vol 3 Self Test Flashcards
What are the four types of tracking energy used in modern missiles?
(1) Light energy.
(2) Electro-optical (TV).
(3) Radar.
(4) GPS.
Which guidance system is nothing more than very high frequency radio waves?
Radar.
What are the three sources that produce the tracking energy used in the guidance systems of
precision-guided munitions.
(1) Active.
(2) Passive.
(3) Semi-Active.
What guidance system allows for a “fire and forget” capability of that particular weapon?
Active.
In what guidance system does the target produce the tracking energy?
Passive.
Which type of guidance system homes in on energy reflected off the target by another outside
source?
Semi-active.
What is the control system designed to do?
Actual steering of a PGM.
What section of a guided bomb do we refer to as the AFG?
Control section.
What are the two types of control surfaces on a guided munition and their purpose?
Fixed and movable. The fixed surfaces stabilize the weapon in flight, and the movable surfaces steer the
weapon.
What are the three different mechanical forces that PGMs use to move control surfaces?
1) Hydraulic.
(2) Pneumatic.
(3) Servo-actuators
What is the science or art of directing PGMs from one place to another?
Navigation.
What is “proportional navigation”?
Movement of the control surfaces is proportional to the error between the flight path of the weapon and the
flight path to the target.
Impact and proximity describe the functioning of what part of an air-to-air missile?
Fuze.
What must take place for an air-to-ground missile to arm?
Sudden acceleration associated with RM ignition and departure from the firing aircraft.
The fragmenting missile case is one way missiles score a kill. What is the other?
Continuous rod construction of the warhead.
What is the purpose of the S&A device?
Keeps the armament system in a safe condition while we are handling the weapon and while the weapon is
on the carrying aircraft.
What are the minimum components of a propulsion system?
The RM and the RM igniter.
Air Force PGM RMs are constructed with what type propellant?
Single-stage, solid-propellant.
What are the three types of RMs used in Air Force PGMs?
(1) Medium thrust.
(2) Dual thrust.
(3) High thrust.
What are the three major component groups of a LGB?
The CCG, bomb (warhead), and AFG.
What is the difference between the GBU-10 and the GBU-12?
The warhead and AFG.
Which CCG is used by the GBU-10 and -12?
MAU-169 series or the MAU-209 series CCG.
What does the CCG do?
Detects laser energy reflected from the target, processes the signals, and guides the weapon to the target.
Which warheads are used by the GBU-10?
MK84 and BLU-109.
What warhead is used by the GBU-12?
MK82.
What are the functions of the WGU-12/WGU-39 series GCU?
What are the functions of the WGU-12/WGU-39 series GCU?
What fuzes are used in the GBU-24 series bombs?
(1) FMU-81/B.
(2) FMU-139A/B.
(3) FMU-143/B, B/B or J/B.
(4) FMU-152A/B.
What does the BSU-84 AFG provide for the LLLGB?
Aerodynamic lift and stability during flight.
What’s the purpose of the ADU-548/B and the ADG-769 adapter group?
Hardback assembly and lug sleeves provide more distance between the bomb and bomb rack, while the aft
fairing assembly provides an aerodynamic interface between the bomb and wing assembly.
Which testers are used for field testing all laser guided CCGs and LGB GCUs?
Digital test set, TTU-373, and TTU-595.
What does the TTU-373 tester do?
Performs a functional check of the CCG or the GCU.
How many modes of operation does the TTU-373 have, and what do they do?
Thirteen modes—six modes to test and troubleshoot CCGs or GCUs; two modes to test and troubleshoot
the DTS; one mode to isolate GCU/DTS problems; two modes to input and display CCG or CGU
parameters; one mode to program a PRF code plug, and one mode to determine GCU mission
configuration.
What hazard is present when the TTU-595 is in operation?
TTU-595 directs invisible laser radiation through its cables and test heads.
Why are JDAMs considered joint weapons?
Both the USAF and USN employ them.
How many GBU configurations are there?
28.
What is the peculiar difference between the different KMU-series kits?
Software and physical interfaces.
What are the components of a typical tail assembly?
(1) Tail fairing/structure.
(2) Tail Actuator Subsystem.
(3) Wire harness assembly.
(4) Guidance Control Unit.
(5) GPS Antenna.
(6) Three moveable control fins and one fixed fin.
Where is the GPS antenna located on the JDAM?
The aft end of the tail actuators Subsystem.
What is the purpose of the aerosurfaces on the JDAM?
Provide aerodynamic lift, maneuverability, and other needed flight characteristics.
Which JDAMs uses the MK-84 2,000 pound GP warhead?
The GBU-31 (V)1 and GBU-31 (V)2.
Which JDAMs uses a 2,000 pound special purpose warhead?
The GBU-31 (V)3 and GBU-31 (V)4.
Which JDAMs uses the Low-Collateral Damage Bomb as its warhead?
The GBU-38 (V)4 and GBU-54 (V)4.
What GBUs are designated as LJDAM?
The GBU-54 (V)1, GBU-54 (V)2, and GBU-54 (V)4.
