2w051 Module 6 Flashcards
what are the four types of tracking energy used in modern misiles
Light energy, Electro-optical,Radar,GPS
Which guidance system is nothing more than very high frequency 2 radio waves?
Radar
- What are the three sources that produce the tracking energy used in the guidance systems of PGMs?
Active.Passive.Semi-active.
- Which type of guidance system homes in on energy reflected off the target by
Semi-active.
- What guidance system allows for a “fire and forget” capability of that particular
Active
- What is the control system designed to do?
Actual steering of a PGM.
- In what guidance system does the target produce the tracking energy?
Passive.
. What are the three different mechanical forces that PGMs use to move control surfaces?
(1) Hydraulic.(2) Pneumatic.(3) Servo-actuators
- 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 section of a guided bomb do we refer to as the AFG?
Control Section
- 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.
What is the science or art of directing PGMs from one place to another?
Navigation.
- Impact and proximity describe the functioning of what part of an air-to-air missile?
Fuze.
- The fragmenting missile case is one way missiles score a kill. What is the other?
Continuous rod construction of the warhead
- What must take place for an AGM to arm?
Sudden acceleration associated with RM ignition and departure from the firing aircraft
- What is the purpose of the Safe and Arming 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
- What are the three types of rocket motors used in Air Force missiles?
(1) Medium thrust.(2) Dual thrust.(3) High thrust
- Air Force PGMs rocket motors are constructed with what type of propellant?
Single-stage, solid-propellant
What are the three major component groups of a LGB?
(1) The CCG.(2) Bomb (warhead).(3) AFG
What does the computer control group do?
Detects laser energy reflected from the target, processes the signals, and guides the weapon to the target.
Which CCG is used by the GBU–12?
MAU–169 series or the MAU–209 series CCG
Which tester is used for field testing all laser guided computer control groups and guidance control units?
Digital test set, TTU–595.
What hazard is present when the TTU–595 is in operation?
Invisible laser radiation is directed through the TTU–595’s cables and test heads. Operators must avoid staring into the cables or test heads
What warhead is used by the GBU–12?
MK–82, BLU–111, or BLU–129
How many guided-bomb unit (GBU) configurations are there for the JDAM?
247
Why are JDAMs considered joint weapons?
Both the USAF and USN employ them
What peculiar differences of KMU-series kits prevent them from being interchangeable?
The guidance software and physical interfaces are peculiar to each warhead
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 are the global positioning system (GPS) antennas located on the joint direct attack munitions?
The aft end of the tail actuator subsystem
What is the purpose of the aero surfaces on the joint direct attack munitions?
Provide aerodynamic lift, maneuverability, and other needed flight characteristics
Which joint direct attack munition is used exclusively by the USAF and utilizes only the MK–84/BLU–117 general-purpose warhead?
The GBU–31 (V)1.
