VLS AND MISSILES Flashcards

1
Q
  1. What are the four ‘cardinal’ rules of safety for VLS?
A
  1. The VLS Mk 41 is operated and maintained only by trained personnel following authorized procedures.
  2. A dead electrical missile interface is always maintained until a missile is intended to be launched with the exception of the procedure outlined by enclosure (1) to NAVSEAINST 8394.2F and restated below.
  3. No simulators of any type will be mixed with live ordnance except during highly controlled special test and evaluation scenarios.
  4. No Developmental Test (DT) ordnance, programs or Weapons Control Systems (WCSs) will be mixed with tactical VLS Mk 41 ordnance or programs.

Q
  1. What safety measures must be used when handling circuit cards?
A

Circuit cards contain Electrostatic Discharge Sensitive (ESDS) devices. Do not touch edge connectors or test connectors when handling cards. To prevent damage to electrical components, use grounding straps when handling circuit cards. Wrap ESDS circuit card assemblies in Electrostatic Discharge (ESD) protective covering and packaging. Observe ESDS handling procedures in MIL–STD—1686.

Q
  1. What is a restrained fire?
A

Restrained Fire is a failure of the missile to launch from the cell and it continues to attempt to leave…all the while continuing to burn inside the cell. It’s a bad day all around.

Q
  1. What is the definition of an overtemperature condition?
A

The deluge circuits in the LSEQ are also activated if a missile is present in the canister and the Overtemp signal from the canister reports an interior temperature of 190 (+8) ‘F or higher.

Q
  1. How much psi is the accumulator tank pressurized to?
A

50 psi ( +/- 10% )

17
Q
  1. How much psi can the accumulator tank drop to before an alarm sounds in CCS?
A

Additionally, there is a Low Pressure Alarm installed in conjunction with a wet type sprinkler system that provides an indication of a pressure drop in the pilot pressure piping below 40 PSI.

18
Q
  1. What is contained in the Damage Control System of the VLS?
A

The system consists of:
a. Hazard monitoring system
b. Deluge system
c. Sprinkler system
d. Plenum drain system

19
Q
  1. At what temperature are the HSDs inside the VLS magazine designed to actuate?
A

160 degrees.

20
Q
  1. How many minutes must the Blowout System be used for before entering the magazine after a launch?
A

The ship blowout system must be operated for a minimum of 20 minutes before personnel are allowed to enter the launcher or environmentally attached spaces.

21
Q
  1. How long must the Blowout System be used for before entering the magazine after a restrained fire situation?
A

After a restrained firing, blowout system must be operated continuously when personnel are in the launcher or environmentally attached spaces until the affected canister is offloaded.

22
Q
  1. Why are there no pre-fire requirements for the VLS? (Use exact wording from the tech manual)
A

Because of the design philosophy, the high state of readiness, and overall reliability of the VLS, pre-fire maintenance requirements are not required.

Q
  1. What are the Test Equipment used when working on the VLS?
A

SW394-AF-MMO-030 contains a full listing of tools, parts, and test equipment. Page 3-42.

26
Q
  1. What is a telemetry round?
A

Used to gather data on missile launch and effectiveness.
