 The amount of time or vane revolutions needed for the firing train to be aligned after a bomb is released is known as what term?? Arming Time. The action that causes a fuze to detonate before impact when any substantial object is dected at a predetermined distance fron the fuze is known by what. Proximity The time required for a fuze to detonate after impact or preset time is known by what?? Functioning time What term applies when the functioning time of a fuze is longer than .0005 seconds?? Delay In its simplest form, what device is like the hammer and primer used to fire a rifle or pistol?? a mechanical fuze What term applies when the functioning time of a fuze is .0003 seconds or less?? Instantaneous The functioning delay of an electrical fuze is initiated by what means?? Electromechanically What term applies when the functioning time of a fuze is .0003 to .0005 second?? Nondelay A fuze that does NOT have the elements of its firing train in the proper position for firing until the fuze is fully armed is known as what type of fuze?? A detonator-safe fuze the distance along the trajectory that a bomb travels from the releasing aircraft in an unarmed condition is known as what?? (SAT) Safe Air Trevel In reference to their primary operating principles, fuzes are normally divided into what two general classes?? Mechanical and Electrical To help make carrier operations safe, a bomb that is accidentally released during an aircraft's landing or take off will NOT normally have sufficient air travel, velocity, or time to fully arm the fuze because of what fuze feature?? Delay arming. The two observation windows of a M904 series fuze are used for what purpose?? To determin the sare/armed condition. On a Mk339 Mod 1 mechanical time fuze, what is the factory preset primary functioning delay time and optional functioning delay time?? 1.2 sec and .4 sec You are checking the EEa of newer models of the Mk 339 Mod 1 mechanical time fuze. The fuze is considered armed if you see what?? A green foil pierced by an indicator pin. The Navy is corrently using which adapter booster?? M148/T45E, M148E1, M150/T46 What adapter booster is used with thermally protected bombs?? M148E1 The Mk 376 electrical fuze provides an all-electric capability for what weapon?? Mk 80 series bombs Arming delay times for the Mk 376 fuze is automatically selected by that means?? A Mk 31 safety device A FMU-143/B tail fuze is used with what weapon?? GBU-24B/B Mk 339 Mod 1 mechanical time fuze is used in what type of ordnance?? dispenser weapons. If deceleration is NOT sensed by a Mk 31 safety device within 2.6 seconds after a free-fall weapon released, the fuze will arm in what maximum number of seconds. 10.0 sec What device provides airburst capability for a bomb inboth the unretarded and retarded delivery mode?? Mk 43 Mod O What is the alternate method for initiating a Mk 43 TDD?? Mechanical What device prevents Electromagnetic rediation from entering the fuze circuits of a Mk 80 series bomb? A Mk 122 arming safety switch In a LDGP bomb, what percent of the total weight is composed of explosives?? 45% What seriese of LDGP bombs are currently in use in the Navy today?? Mk 80 An FMU-140/B proximity fuze will funtion at what minimum altitude?? 300+- 25 ft A bomb body is shipped with a plastic plug installed in the nose and tail fuze wells to prevent what occurense?? Damage to the internal threads and moisture entering the fuze wells. What factor determins the number of bombs that are loaded oneach metal pallet?? The size of the bombs What total number of Mk 83 GPBs can be placed ona metal pallet?? Three When electric fuzing is used, a path for the charging current fromthe fuze-charging receptacle to the forward and aft fuze wells is provided by which of the following mechanisms?? The electrical fuze wire harness A thermally protected GPB is identified by what markings?? Two yellow bands around the nose Arming wire assemblies are used for what purpose?? To maintain ordnance somponents in a safe condition until the actual release of aweapon form an aircraft. Premature or accidental withdrawal of an arming wite from a component is prevented by the installation of what device?? Safety clips A conical fin assembly is used with what delivery mode?? Unretarded only What is the basic difference between the types of conical fins?? Physical size. A conical fin assembly is attaches to the aft end of a bomb by what means?? Step screws To prevent damage to an aircraft from ricocheting bombs or fragments during high-speed, low-altitude delivery, what fin assembly configuration should be used with LDGP bombs?? Snakeye, retarded mode The MAU-91 fin is attached to a Mk 83 bomb by what means?? An ADU-320/B fin adapter MAU-91A/B and B/B Snakeye fin assemblies are used on shich of the following LDGP bombs?? Mk 83 To provide the pilot with in-flight selection capability, the swivel loop of a Snakeye fin release wire is connected to what component?? The tail arming solenoid What LDGPBs can be confiured as laser-giuded bombs?? Mk 82, 83, and 84 The computer-control group (CCG) of a laser guidance kit is used for wha purpose?? To detect laser-illuminated targets and to provide an attachment point for the guidance fins. A GBU-24B/B will penetrate how many feet of reinforced concrete?? 4 to 6 ft The total amount of thermally coating missing from a GBU-24B/B must NOT exceed what amount?? 40 sq. in. DSTs are identified by what color stripes?? White What kit should you use to configure a LDGP bomb to a DST? Mk 75 Which of the following components is requires with a Mk 42 firing mechanism?? A battery A Mk 20 bomb cluster is designed for use against what kind of targets?? Armored vehicles What total number of bomblets is contained in the Mk 20 bomb clusters?? 247 What fuze is used with the Mk 20 bomb cluster?? Mk 339 Mod 1 The spring-loaded fins attached to the tail cone assembly of a Mk 7 bomb dispenser are secured in the closed position by what retaining devise?? A fin release band assembly What total number of BLU-91 mines are contained in a CBU-78 Gator?? 45 A Mk 339 Mod 1 mechanical time fuze is used with what modification of a Mk 7 bomb dispenser?? Mod 3 What Modification of a Mk 7 bomb dispenser is thermally protected?? Mod 6 The Mk 339 Mod 1 mechanical time fuze has what ptimary or optional time settings?? 1.2 and 4.0 When both the primary and optional arming wires are pulled form the Mk 339 Mod 1 mechanical time fuze, the fuze will function within what time??
