Without AIP sub can do around 10 kts underwater for around 3 days which translates to around 720 nautical miles. This is because most of the fuels, oxidizers and other consumables used in AIP are quite expensive and it would not be economical to replenish them on a monthly basis.The capacity and reliability of batteries is increasing due to extensive research being conducted in that field.

Sorry for asking off topic question but I don’t getting answer elsewhere.

Wherever Iam reading , they are talking of Tejas being obsolete and pitching Tejas against rafale for mmrca need.

Some examples are the Before we can understand the working of AIP systems, we need to understand the meaning of a few engineering terms.This technology involves storing a supply of oxygen in the submarine in order to run a diesel engine while submerged. Already read the majority of them in the 4-5 days since i*ve found this website, looking forward to new articlesThanks NRP for providing detailed answers. L' Air-independent propulsion (in sigla AIP, in italiano Propulsione anaerobica) è una tecnologia di propulsione navale che permette ad un sottomarino non nucleare di operare senza aver accesso all' ossigeno atmosferico (cioè senza andare in superficie o senza usare lo snorkel).

3. The 100 Mk1A will replace the old MiG-21 in point defense roles and will have a secondary precision strike role. As battery technology improved, the endurance of these submarines increased proportionally. This is because it has its own fuel supply independent of the fuel supply to the diesel engines. As installed on the Nuclear reactors have been used for 50 years to power submarines, the first being There have nevertheless been suggestions for a reactor as an auxiliary power supply, which does fall into the normal definition of AIP. This will allow them to continue sailing underwater and retain the element of surprise by remaining undetected. They have a large network of batteries which are charged by the diesel generator. They will see if they need another fighter in light fighter category.

Do you think the Tejas mark 2 can match the f16, gripen 39, mirage 2000 in terms of pure flying capabilities like max speed,angle of attack, maneuvering, g force limits,altitude,climb rates etc.

F16 is its direct rival from PAF.

Well I understood your point that Hal doesn’t reveal actual specification, but don’t you think that a company who think that its product has an export potential degrades its specification significantly.

In nuclear powered submarines, the reactors provide the heat in order to convert water into steam.

The submarine could also run its diesel using a snorkel. Sorry, your blog cannot share posts by email.

Modern non-nuclear submarines are potentially stealthier than AIP is usually implemented as an auxiliary source, with the traditional diesel engine handling propulsion on the surface. Although the submarine eventually needs to surface to charge its batteries and their endurance is nowhere on-par with nuclear powered submarines, the vast increase in endurance offered by AIP gives them an advantage over non AIP equipped diesel-electric submarines. N.R.P. always love reading your blogsVery informative and enlightening piece of information.Waiting for more.Thanks.

But the professionals know better. The circle of manufacturers is for the time being very limited.

AIP can augment or replace the diesel-electric propulsion system of non-nuclear vessels.

But it was not enough to last t…

I’ve already written one on INS Vikramaditya.A thoroughly enjoyable read, as always.

Thus in this situation where intelligence is gathered and spy missions are performed, AIP gives these quiet diesel subs an advantage by allowing them to loiter for weeks without the need to surface.The thing to remember about AIP is that just because a submarine is equipped with that technology, it wont necessarily use them on every deployment.

Many countries are operating both nuclear and diesel-powered submarines for their respective advantages. I have received over a hundred article requests till now Excellent article! Several experimental boats were produced, and one, This technology uses a submarine diesel engine which can be operated conventionally on the surface, but which can also be provided with The German work was subsequently expanded upon by the Soviet Union who invested heavily in this technology, developing the small 650 ton In the Soviet system, called a "single propulsion system", oxygen was added after the exhaust gases had been filtered through a lime-based chemical absorbent. These batteries run out of charge within 4-5 days and the sub needs recharge them. If the sub travels at this speed for 15 days, it would have covered 1800 nautical miles.
