 |
|
Salve, sono ancora alle prese con 688(I) Hunter/Killer! Volevo chiedere due cose.
-Nel manuale Blue Book ho letto che il cono di acquisizione di un siluro è tridimensionale. Ha un diametro orizzontale di circa 5.000 yards. Vorrei sapere la misura di quello verticale. Quanti piedi in verticale copre?
- Mettiamo che lancio un siluro in modalità passiva a corsa lenta(35 nodi). Quando il siluro acquisisce il bersaglio aumenta automaticamente la sua velocità fino alla massima oppure resta alla velocità pre-programmata? E ancora: passa in modalità attiva o resta passivo?
Vi ringrazio per la pazienza e per le risposte!!!
Salve e...buona caccia! Schaitan |

Hi, I will answer your questions directly in english because most forumers don't understand nor read italian.
In any case speaking of acquisition cones, a cone has a circular section that means that the horizontal and vertical diameters coincide.
No, the speed of the torpedo is fixed at launch time. If you fire a passive torpedo at 35 knots and it acquires a target it will continue at the same speed and will not accelerate.
The torpedo doesn't automatically change passive and active modes.
Good hunting  \
Ps: stop playing 688i h/k and buy Dangerous Waters  |

Come on kapitan, you can surely guess what the questions where from the answers I gave him.
In any case he asked wether once launched a torpedo in passive mode at 35 knots, the torpedo would accelerate once acquired its target, and once acquired its target whether it would change automatically from passive mode to active mode.
The other question regarded an issue in the blue book regarding the term acquistion cone. He was asking what was the vertical aquisition diameter.
Since a cone has circular section, the horizonatal aquisition distance = vertical acquisition distance.
Last but not least, these questions were asked for the game 688i h/k. |

Ciò vuol dire che un siluro attivo può pingare un target da una profondità 0, per esempio, ad una profondità di 5000 yards( più di 15.ooo piedi)? Che senso ha se il settaggio della profondità massima di operatività non va oltre i 3000 piedi?
Nel Blue Book si afferma il contrario riguardo la seconda questione. Un siluro a lenta corsa, una volta acquisito un bersaglio, accelera fino alla velocità massima. Sto leggendo manuali diversi e alcuni si contraddicono e comunque credo che questi questioni esulino riguardino cognizioni valide per tutte le sim sottomarine e navali in genere. Non so a chi credere!!Comunque ti ringrazio! Buona caccia!! | goldorak wrote: | Hi, I will answer your questions directly in english because most forumers don't understand nor read italian.

I'll translate what he said. I'm a bit "multilingual"...shall we say. Though someone else must answer because my sub skills aren't that good. 
"So does it mean that an actively homing torpedo can ping a target from a depth of 0, for example, to 5,000 yards (more then 15,000 feet)? What's the point if the torpedo has a maximum operating depth of not more then 3,000 feet?
In the Blue Book the contrary is written regarding the second question. A torpedo set at a low speed, once acquired a target, will accelerate to it's maximum velocity. I'm reading different manuals and some of them are contradictory and anyway I believe these questions are relevant for all sub and naval sims in general. I don't know who to believe!! Anyway, I thank you. Good hunting."
Now if someone would like to answer him...cos I have no clue. :doh: |

Well...With the 688I game I played for several years...I would have to disagree...
If a speed on either fish (active or passive) was set at anything less than 55 knots...it would remain at that speed untill a target was aquired, THEN accelerate to 55kts...and stay there |

Salve! (Latin)
I am currently a team member on a mod team... the next version of the mod will have this kind of behavior for torpedoes, as well as many other improvements.
In the mean time, you may enjoy LWAMI 3.02 (link on the bottom of my signature)!
Cheers,
David |

A torpedoes , and also a mine, can be a efficient reflector for active sonar searching? It can help for spooke an incoming torpedoes ?
It can became an valid countermeasure?
Tanks, and...good hunting Schaitan |
