Provide positive control of the warhead, arming and fuzing

Question 7

(010) 2. What purpose does the J-box serve in the SAF system?

Answer 7

It supplies the generator power to the three specific power busses: pulse load, constant load, and main load

Question 8

(010) 3. Which component provides safeing control and monitoring functions in addition to serving as the electrical interface between the warhead and other system components?

Answer 8

The warhead arming device (WAD)

Question 9

(010) 4. The impact fuze assembly consists of how many sensors and in which section of the missile is it located?

Answer 9

Three; the forward section

Question 10

(011) 1. The proper operation of the SAF system relies initially on functions provided by who and what functions do they provide?

Answer 10

The carrier aircraft crew. Nuclear consent, permissive action link (PAL) activation, unique signal generator activation, and coded switch enabling.

Question 11

(011) 2. Explain the purpose and the development of the “ESD words”.

Answer 11

To ensure proper sequencing of events, The first word- ESD parent word- is issued by the carrier avionics control unit (ACU) to the missile INE, 250 milliseconds prior to launch and is used to set up the sequence of events. The second ESD word is made up by the INE based on the parent-word and is an accumulation of 16 events.

Question 12

(011) 3. Which two events required by the ALCM and CALCM equate to good guidance?

Answer 12

100-nautical mile check and final terrain correlation

Question 13

(011) 4. What is impact fuzing?

Answer 13

Programmed ground burst. It is also used as backup in the event inertial fuzing does not detonate the warhead.

Question 14

(012) 1. What two methods of heat transfer of cooling are used within the environmental control system?

Answer 14

Active and passive

Question 15

(012) 2. State the difference of how heat is removed from a component using the two methods of heat transfer or cooling?

Answer 15

Active ECS cools those components that generate a significant amount of heat and therefore requires additional cooling. The passive ECS cools components tat do not generate excessive amounts of heat and therefore, utilizes a different method of cooling-conduction or transfer of heat from one surface to another.

Question 16

(012) 3. What is the primary purpose of the forward environmental control element?

Answer 16

To provide active cooling to the INE

Question 17

(012) 4. How many poppet valves are inside the umbilical enclosure assembly and what purpose do they serve?

Answer 17

Two; to direct the flow of supply and return air

Question 18

(012) 5. There are two distinct airflow path concerning the forward ECS, when do they occur?

Answer 18

Captive carry, ground checkout, and free flight

Question 19

(012) 6. What is the purpose of the aft environmental control system?

Answer 19

To provide cooling for the generator/regulator and engine during free-flight only

Question 20

(012) 7. The GMFC and CMRA produce a fair amount of heat, what provides these components with supplemental cooling during ground checkout?

Answer 20

By the CCU through a fitting in the payload bay.

Question 21

(013) 1. What does the engine inlet seal provide for the engine intake?

Answer 21

A moisture barrier

Question 22

(013) 2. What detects moisture presence within the desiccant system?

Answer 22

The visual humidity indicator

Question 23

(014) 1. Which system provides fuel to the engine?

Answer 23

The fuel containment and transfer (FCAT) system

Question 24

(014) 2. During missile fueling, which tank is filled after tank 4 is full?

Answer 24

Tank 2

Question 25

(014) 3. The turbofan cruise engine produces how many pounds of thrust and uses what type of fuel?
