244/s

[sail]

if to someone can interest, in these days, to livorno, on the occasion of the trophy naval academy, at the booth wass/Finmeccanica it is possible to see and touch a split of a light to244/s

ed un blackshark.

it is interesting to see the use of composite details (coated battery pack for 244/s and propellers for bs).

Moreover, I am curious that the bow of both fishes is flat. do you need for sonar issues? other reasons?

It's probably a cavitating torpedo, I think the flat part is used to create liquid vein detachment from the surface of the torpedo itself, replacing it with a layer of steam.

I don't think so. First of all, the speeds of objects do not justify such a solution, moreover supercavious torpedoes do not use a conventional propulsion to propeller, but to rocket. because the whole body of the torpedo is immersed in the bubble of cavitation.

that of the photo posted by sail, is a “a-184 enhanced” whose last version, the 3, is called black shark.
This is a heavy electric propulsion torpedo with a new engine more powerful and propellers to counterbalance, proguided, able to reach the 50 knots with an autonomy of 50 km whose development began in 1997. the guide is combined between fiber optics and active/passive astra sensor.
carries a 250 kg explosive test of hbx explosive. has a diameter of 533mm, a length of 6 meters and weighs 1265 kg.

wass, a Finmeccanica company specializing in the underwater sector, is a Livorno company with a history of more than one hundred years of activity and that has recently changed its name in whitehead underwater systems keeping unchanged the acronym wass and is without doubt, the world leader in the field of heavy torpedoes, light ones and unique case in the world, also in the field of countermeasures being the company wass, the company and the
The black shark is a very sophisticated torpedo that contains a concentrate of technologies such as propulsion and fiber optics. developed for export, this torpedo was integrated on German platforms of type u209, u214 and u212, French-Spanish type scorpene and Russian type kilo, was acquired by the Chilean, Indian, Malaysian, Peruvian, Portuguese and by those of taiwan and singapore for more than 100 specimens.
meanwhile wass is developing the new heavy torpedo intended to replace the a-184 mod.3 on the Todaro class (u212). the insp is the national variant of black shark reached the third stage of development.

the a244s is instead a light torpedo that should be replaced by a new generation model called "flash back", designed to be launched by unmanned ships and vehicles of surface, aerial platforms with fixed and rotating wing and the predisposition for the use of launch from underwater platforms with philguida, a performance adopted for the first time and of particular interest for all those operators of platforms called midget or mini-sommergibili. other performance of significant interest is that the new weapon system is not only able to engage both conventional and nuclear surface units and underwater platforms but also attacking torpedoes.
consists of 4 sections (guide, warhead, battery, powertrain) instead of the classic 5. the section dedicated to discovering and driving systems has been integrated among them. the flash back is made of carbon fiber and aluminum. Rechargeable propulsion batteries are lithium-polymer with commercial derivative cells (cots) able to offer performance higher than traditional ones. these batteries give rise to lower maintenance costs without counting that the weapon can be launched several times for training activities (30 times in exercise of which 5 consecutive) before undergoing controls over the time of its operating cycle.
the black flash has a diameter of 324 mm but can still be launched from a 533 mm tube with a special adapter, develops a maximum speed of over 50 knots, has a distance of engagement of more than 20,000 meters, is able to operate in salt water, sweet and in closed water mirrors and allows to operate in a wide range of operating quotas. the guide is active/passive acoustics and the torpedo has the ability to approach silently to the target and is able to automatically chase the trail of the surface unit propellers (wake homing).
this makes it ideal for non-lethal attacks against commercial ships that could be seized for piracy purposes or for terrorist attacks.

the supercavious torpedo of which speaks hunter is the Russian shkval of which we spoke above and under the waves.
an 8.2 meter long weapon, 533mm diameter and an estimated weight in 2700 kg of which 210 tnt explosive. the maximum speed should be almost 500 km/h with a useful range of 7000 m. the improved version of the shkval, the shkval-e, sold in the 1990s in about 40 pieces to the cina. In recent years Europe has not been watching and in the meantime has realized at least two types of supercavitation torpedoes, the English mk70 spearfish and the German barracuda.

in the attachments, a black and a244s at launch.

I'm curious and I've been looking for a little bit: you're probably right in saying that the flat tip serves to ensure better sonar performance.

 

[Exatem]

the supercavious shkval.

 

[Er Presidente]

...with an autonomy of 50 km whose development began in 1997. the guide is combined between the thread.. .
...

50 km...Filoguidated... and what's the 10 mt roll in diameter?

 

[Exatem]

50 km...Filoguidated... and what's the 10 mt roll in diameter?

precise...
the "filo" of those currently included is around 14km. the rocchetto is inside the torpedo itself and starts with a connector, at the bottom of the closing door of the launch tube.
Anyway, I didn't say that he's prosecuted for 50 km... but that the torpedo has an autonomy of 50 km.:mixed:
It's always equipped with a looking head.

So after 14 km the leash breaks and the "mask" is "enclosed" in " autonomy"?

:biggrin:

:biggrin:

Why, how do your "birds" do?
after the landing on the radar of the enemy plane launch the missile that, is guided on the target by the illumination of the radar itself (or by a friend)or, "launch and forget" with the missile that follows the thermal trail, radar, etc...
and the engagement also happens beyond the horizon then on a target that you physically do not see.
It takes some confidence in systems...:tongue:

But he's "the bird" or he's "active" or "teleguided", it's not like a guy shoots a strand, and then when he's sick, he's gonna let him go for his count!
:biggrin:

:biggrin:

Maybe not just when "one got tired." .
However, even the torpedoes are "passive", "active".
the difference is that instead of "teleguidati", they are "filoguidati".
We're a step back, all right?
(so the president is satisfied with the air supremacy conquered!):wink:

[rinato]

Hello, as a profane I would say that in water it is more difficult to teleguide something, especially if submerged, and then you have less enemy interference.
At the limit, licensed, you could also fish us, like the kevin kostern in "waterworld". . .

wass recently presented flash black, an unconventional light torpedo designed and developed entirely by the company to meet all the strictest operational requirements in the anti-submarine war.
flash black incorporates a series of innovations in terms of flexibility of use, performance and reduced cost of the product life cycle.
it is launchable from any platform: In addition to the usual ones, such as surface units, helicopters and aircraft for the marine patrol, is previewed the launchability also from underwater platforms and from vehicles without pilot.
the torpedo is effective against each target, from conventional and/or nuclear submarines (both lying on the bottom and counter-managing at full speed), to midgets, from hijacked ships to heavy torpedoes attacking the launch platform (anti-siluro), and can be used in any environment (including coastal waters and confined water mirrors).
The black flash also ensures full effectiveness and high probability of destruction even in the presence of the most sophisticated countermeasures systems.
the torpedo can be used successfully also against surface units, given the high ability to inflict serious damage to medium-small units (e.g.: liquid gas transport ships for anti-piracy purposes) and to perform a non-lethal attack on large military units, thus making propulsion and/or thymones unusable.
It is also prepared to be propelled in the case of launch from underwater platform, it is equipped with an electric propulsion system capable of guaranteeing a peak speed of over 50 knots and to engage a target of more than 20 kilometers. This system consists of a pump-jet engine (derived by mu90), a new alternating current engine and an innovative rechargeable battery that uses state-of-the-art lithium-polymer technology.
the motor allows the black flash to approach silently to the target reducing to the minimum the distance of the counterdiscovery.
the battery can be recharged for a very high number of cycles (about 100) thus reducing the cost of the gun life cycle.
the front section of the torpedo contains a planar acoustic antenna with a profile that minimizes the noise generation even at maximum speed.
the black flash can run up to 30 launches in operation (of which five consecutive without the need for disassembly).
reduced maintenance allows you to have a cost ratio of the double life cycle compared to any other torpedo in the world.
Another unique black flash player is the use of composite materials such as carbon fiber, for structures.

and this is how...... Hi.

 

[Exatem]

I don't usually talk about weapons or weapon systems. I don't understand a snitch. but this time I can make an exception.

skin

and this is how...... Hi.

we have drawn from the same "supplier". . .

I'll explain why.
when the topic are weapon systems, especially of last generation, the risk of treating confidential arguments is quite high.
then to not miss, it is preferable to report as already public domain on any website easily accessible.
are fundamentally the same news that can be found on the sites of the companies producing or on any magazine in the sector (for example).
Ultimately they are "precautive plagiarism".

 

[Er Presidente]

...

...

me cojioni... 100 cycles!
That's great.
but do polymer lithium battery builders know?

p.s.: maybe it's a refuso, or maybe it's the harsh reality, the military apply the norms and don't "marketing".

 

[Fulvio Romano]

Who explains to me what "float" means? (exatem, obviously I have it mainly with you...)
I'm... I'm ashamed.

15km...what thread is it? size? weight? What's in it? information? power?

If the spool is on the torpedo, I imagine that the thread does not make any resistance, because it is "flow" than water...right?
but for the enemy not enough to intercept the wire to put ko the torpedo? and to mate with a wire of a few miles is not that it takes much... the coffee key works so... where am I wrong?

 

[Er Presidente]

The wire is "millimeter" and takes the signal to drive it to the target.
in the 1973 war on the heights of the golan in the "valley of tears", hundreds of Syrian tanks were destroyed by the Israelis.
there was an intense use of philguided missiles (tow) and after the battle the field was sprinkled with an intricate wilderness of thousands of abandoned wires.

Soon it turned out that the smoke of the explosions blinded the "pointers" and that the car to defend itself had to shoot near the missile, in its wake, hoping to interrupt the wire with the explosion and raising a cloud of smoke to prevent the pointing to the enemy.
