I am an Aerospace engineering student. There I might be able to answer ur question.Red aRRow said:The intakes of the JF-17 have been modified. They are now DSI (Divertless Supersonic Intake). Here are some links to pictures:

Any ideas how DSI helps an aeroplane? I can think of just the reduced Radar Cross Section (RCS) of the plane. Any other benefits?
No. Radar absorbing material is typically less than 20% of the process required to reduce RCS. You also cannot stick RAM everywhere like body filler - thats not the way it works.hovercraft said:1 - radar cross section is only reduced by radar absorbing paints which contains graphite particales the reduces the radar waves and makes the surface invisible examles are F-22, F-35 and B-2.
NO! The fundamental issue is initial design. That means signal deflection issues at various aspects - composites do not have to cover the "whole external body of the plane". Your examples are incorrect because both Gripen and Rafale are not complete composite bodies.hovercraft said:2 - second method to reduce radar cross section is use of composite materials like carbon fibre and glass fibre in whole external body of the plane example is swidish gripen fighter and maybe french rafale too
This is the highest priority. get the basic design wrong and all the RAM in the world won't make it stealthy.hovercraft said:3 - third is to make a special design that reflects the radar waves on safe positions or angles example is F-117 night hawk
SAMS are a important issue but PAF could deal with that at a latter stage when the bloddy jets arrive. (when ever that is). anyway new article.mysterious said:Doesn't matter how many in the 'pipeline' until we actually draw them out of that pipeline and put them on the ground, fully upgraded and ready to go. I must say I am losing patience with PAF's acquisition strategy. They're sitting on their laurels while all around them, potential rival forces are busy in their shopping sprees!
As Elite pointed out, its not just acquisition of more fighter jets that is required by the situation but long-range SAMs are a MUST for the defence of the Pakistani AirSpace. PAF currently operates OBSELETE SAMs which won't even stand half a chance against an aggressor threat. Its about time PAF acted instead of boasting that Pakistani air-defence is impregnable!
Firstly I'd say its good that Air Marshal Kaleem Saadat is looking towards radars and hopefully. Personally if there is one thing I must say is that Pakistan relys VERY HEAVILY on its own hardware. Yes, i know thats sort of good but its really not since you cant get any new SAM's without Pakistan looking deeply into the ANZA. I would really like to see Pakistan create its own SAM's that are comparable to the ones in the international market. Futher to this is the JF-17, again, i know its a Sino/Pak aircraft and is the first fighter jet Pakistan is going to manufacture but Pakistan is way to devoted to it.‘New and used F-16s may be bought’
KARACHI, Jan 20: The Pakistan Air Force is considering buying a mix of new and used F-16 fighter jets, says Chief of Air Staff Air Chief Marshal Kaleem Saadat.
The PAF chief was addressing members of the English-speaking Union of Pakistan (EUP) at a local hotel.
Highlighting the PAF’s high deterrence value, he said Pakistan was fully capable of defending itself and he hoped there would be no war.
He said that maintaining a strong and credible defence was expensive, and pointed out that the PAF needed hardware worth $3-4 billion to maintain a minimum deterrence capability.
He said that various versions of F-16s were available to PAF from the United States. “We are also considering to buy used F-16s from elsewhere. However, we will prefer a mix of new and old F-16s fighter planes for the PAF,†he added.
He said the PAF was focusing on strengthening its reconnaissance and surveillance capability, strike power, detection of enemy aircraft, platform to combat and weapons for defence.
The PAF chief reminded that India had withdrawn its forces from the border with Pakistan after nine months as western countries issued travel advisories asking their citizens not to travel to India in 2002.—PPI

Congress F-16 notification soon: report
ISLAMABAD, Jan 30 : The Bush Administration is set to re-notify the US Congress to carry forward the deal of F-16 fighter jets as the deal is now back on track after it was deferred due to of last year’s earthquake, a media report said on Monday.
Pakistan had postponed the $4 billion pact to buy as many as 75 F-16 fighter planes from the United States after the massive earthquake on October 8 last year that killed over 73,000 people. However, a senior official here said as result of conclusive talks recently held between Islamabad and Washington during the Prime Minister Shaukat Aziz visit to US both the sides had decided to revive the agreement on F-16s, The Nation newspaper reported.
He said the Bush Administration would re-notify the Congress on the vital defence deal by February end or start of the March after which all would be cleared to go ahead with the agreement.
He said the pact was put off earlier because Pakistan was uncertain about the world’s response to the October 8 quake that caused colossal losses.
However, the positive response on the part of international community to Pakistan’s relief and reconstruction needs had encouraged Islamabad to go ahead with the F-16s deal, he maintained.
Pakistan managed to get financial commitments of 6.8 billion dollars for relief and reconstruction work in its quake-affected areas at the international donors’ conference held here in November 2005 for the purpose.
The official said much of the process to estimate the financial losses had been completed and keeping in view the donors’ commitments Pakistan was confident enough that it could go on with the vital defence deal.
Asked whether Pakistan would also go forward with another defence agreement for the purchase of six early warning system aircraft from Sweden worth one billion dollars, he said he had no knowledge of latest developments vis-Ã -vis that very deal.
4 billion? the original price was 3 billion has Pakistan asked for something more? maybe more missiles? Well atleast its back on track, thats more than what i could ask for.Pakistan had postponed the $4 billion pact to buy as many as 75 F-16 fighter planes from the United States
Different news agencie have different & various sources & when too many people get one report & all of them get to tell it than the confusion starts. Any wya my own guess is that deal is no less than of $4 billion. Couple of months back US officials said Pakistan had planned to buy 75 NEW & only 11 OLD F-16s. 75 new f-16s cant be less than $4 Billion.Elite-Pilot said:4 billion? the original price was 3 billion has Pakistan asked for something more? maybe more missiles?

True, because the PAF will also need to pay for infastructure, spare-parts, training, weapons, etc; it will definately cost over 4bn USD. I'm just wondering if PAF will get some Block-52+ - CFTs, bigger spines, etc.Couple of months back US officials said Pakistan had planned to buy 75 NEW & only 11 OLD F-16s. 75 new f-16s cant be less than $4 Billion.
I dont know man, Block 52+ is a gamble. Pakistan is still looking towards choosing a new 4th generation fighter. The F-16 block 52+ has a ability slightly higher than the original 52 model and cost about 5 million more. Personally i want to see a fighter like Rafale in the PAF's inventory. However, Rafale is about 80 million USD which makes it a costly price and the fact that it has one of the best technologies aboard a plane make a wonderful option. 40-45 Rafales can serve extremely well, infact i am so confident in its abilities that i'll say it can shoot down TWO Su-30MKI's in an engagement.True, because the PAF will also need to pay for infastructure, spare-parts, training, weapons, etc; it will definately cost over 4bn USD.

Embargoing Pakistan did not achieve anything except more complications. Did stopping F-16s stop Pakistan from having nuclear weaponry? Did stopping F-16s stop Pakistan from starting the JF-17 project? At the loss of 70 odd F-16s valued less than 2bn USD Pakistan gained power worth a lot more (actually kind of priceless and much longer-term).This is what i dont get, alot of people assume the United States will deliver all 75 F-16's but how do we know FOR SURE that we will recieve them all? i dont wanna hear things like "um....because we are helping them with the War on Terror" i want to listen to something more interesting. Like what are the chances of Pakistan to recieve all those F-16's?
1. i dont see it as a good idea to blame IAF for bad condition of PAF.. india is a much bigger economy and so more military spending in imminent.Elite-Pilot said:I agree with you Bilal, and i understand exactly what you are trying to say. America offers India F-18 E/F & F-16 Block-70 while they are just sitting down and drinking tea and we deployed around a 10,000 troops along the Afghan border, making fences and holding back refugees. It was the Indian Air Force that started this Arms race in South Asia, it was India which yet till today wants to dominate south Asia regardless of keeping defence balance.
Bilal, the PAF hasn't seen anything advanced in its arsenal for A LONG time. It's time for a change. Pakistan definately needs a new fighter plane platform. I managed to dig up some stuff on the Rafale, turns out PAF is just not in favor of it but rather the Euro-fighter would be more suitable for us. There are only a few Air crafts pakistan is actually looking towards.
J-10 (which i think we should lay off and wait to mature)
Euro-fighter (is just perfect for our new platform)
Rafale (failed to meet complete our standard):
Besides these air crafts there is just nothing there for the PAF.
