Then there was the subject of of how water has small viscosity and other fluids high.Also things like that the viscosity of air could be gauged by the air tempture. It was all about learning the aero dynamics how drags can be generated. We also studied the Stress mechanics which had alot of units like megapascals from memory other things like deformable body stuff as well. It was alot of Physics and calculas involved.

Anyway, i'm off to work for 4 weeks now so i wont have access to to my laptop for a while i cant log on for around 4 weeks.

It sounds like you guys got a lot more of the raw theory than we did. I had many aerodynamics courses, but I don't recall it going that deep. We were more into Reynolds numbers, airfoils, and the makeup of the atmosphere. I've forgotten it all because it has little to do with actually getting about in an airplane.

Why bother to learn how to calculate true airspeed based upon air temperature, altitude, indicated airspeed, etc, when there is a digital readout of TAS right there on the display?

Tell me about it. . I would spend maybe around 3 to 4 hours a day just doing revisions on these stuff on how the the vertical stabilizer is based on the airfoil area.. They were very strict about it .They wanted us to know the exact parts of the plane that was in the vicinity of airfoil section. Then how we could use the aerodynamic the best way for different angles of attack.It wa pain stakingly boring.


The Physical Training i thought wa alot easier. lol.

Greetings IR, well there was no sarcasm and I just asked if when Iranians say manufacture they meant rebuilt. I do not read or write in Arabic so I would not know what they say in the Iranian news that someone posted. And I said there is no shame in rebuilding/upgrading systems and everyone does it. I don't see where I would have insulted Iranians or being sarcastic. Anyways thanks for letting me know they Iranians said that it is a rebuilt.

Even if you could read and write in Arabic...you wouldn't understand what Iranians were saying...Iranians don't speak Arabic..the official language of Iran is Persian!

Greetings Iran33,
I meant I do not read the arabic alphabet, anyways there seems to be a great deal of confusion in the Iranian side about what manufacturing means. Some here think it means building from scratch while others can safely say that manufacturing can also mean rebuilt or upgraded.

Israel Says Iran Choppers Launched in Navy Drill Better than US Cobra

Israel Says Iran Choppers Launched in Navy Drill Better than US Cobra
07/05/2010 07:29:12 PM GMT

Israeli military sources have said that the Iranian Toufan (storm) chopper launched during the Iranian 8-days navy drill was heavily upgraded and much (more)


Israeli military sources have said that the Iranian Toufan (storm) chopper launched during the Iranian 8-days navy drill was heavily upgraded and much better than the US Cobra.

Iranian made Cobra choppers took off and landed on Iran’s army naval force battleships during this phase of the war game in the Straight of Hormuz and the Sea of Oman, successfully carrying out tactical operations. They attacked and shot down surface and sub-surface mock enemy targets during the second day of naval drill dubbed (Velayat-89) on Thursday.

Iran's helicopter gunships were also dispatched to the area to act as covers for Cobra choppers during the tactical operation in Iranian territorial waters.

Debkafile's website quoted Israeli military sources as saying that if Iran has indeed designed a weapon of this type and quality (Toufan), it has come up with a powerful answer to US and Israeli cruise missiles, which pose the “biggest threat� to Iran's nuclear facilities in a military strike.

The Iranian Air force have received 10 new "Toufan" attack helicopters based on the Bell AH-1K Sea Cobra design. After studying photographs, Western military sources reported the Iranian version has been heavily upgraded compared with the original.

Debkafile's intelligence sources also note that the Iranian Air Force's Badr Base for light aircraft and helicopters in Esfahan, central Iran, accommodates 1,000 aerial military vehicles of different types, and is the biggest air base of its kind in the Middle East and Southwest Asia.

Iran has also successfully conducted interception operations by drones on Thursday. Flying surveillance drones could gather information about hypothetical enemy forces.

Iran's defense minister Brig. Gen. Ahmad Vahidi had also announced on Wednesday the development of the "Mesbah 1" (Lantern), the new air defense system for countering aircraft, cruise missiles, choppers and other low-altitude threats. He said the new system, which is capable of firing “four thousand rounds per minute,� has unique features that differentiate it from other similar air defense systems.

The new system is equipped with a three-dimensional interception radar and an optical guidance system, he added.

In the meantime and according to Fars news agency, Iranian Navy destroyers accompanied by frigates and submarines carried out reconnaissance missions during Thursday's maneuvers.

Admiral Qassem Rostam Abadi, the maneuvers' spokesperson, said the reconnaissance missions were aimed at securing Iran's shipping routes in the Sea of Oman. The Iranian army is scheduled to carry out electronic and anti-electronic warfare and gather radar information in the region, the military official added.

Meanwhile, Brigadier General Kiumars Ahadi -- another commander with Iran's Military -- said troops and military hardware will be dispatched to the area during the drill through special operations.

Iranian Navy commander Rear Admiral Habibollah Sayyari said earlier that by holding the maneuver, Tehran sought to send out a message of "peace and friendship" to regional states.

Late last month, Islamic Revolutionary Guard Corps (IRGC) staged four days of maneuvers in Persian Gulf and Strait of Hormuz, testing missiles and a new speedboat capable of destroying enemy ships.

The development of the "Mesbah 1" (Lantern), a new air defence system for countering aircraft, cruise missiles, choppers and other low-altitude threats, was announced by Iran's defence minister Brig. Gen. Ahmad Vahidi Wednesday, May 5. It will go into operation in the near future. debkafile's military sources say that if Iran has indeed designed a weapon of this type and quality, it has come up with a powerful answer to US and Israeli cruise missiles, which pose the biggest threat to Iran's nuclear facilities in a military strike.
Vahidi boasted that the Mesbah can fire 4,000 shots a minute, is very precise and can be operated by a smaller crew than similar artillery systems. He claimed it was also effective in tracing and shooting down unmanned aerial vehicles - drones.

The Iranian Air force is also reported to have received 10 new "Toofan" (Storm) attack helicopters based on the Bell AH-1K Sea Cobra design. After studying photographs, Western military sources reported the Iranian version has been heavily upgraded compared with the original. It has a narrower airframe for greater flexibility and is armed with M197 3-barrelled 20-mm "Gatling-type" cannon in the A/A49E turret. Its wing-stub stations carry a pair of 19-tube 70-mm rocket launchers. The rear section has a Vulcan-type 20-mm automatic cannon, and two clusters of 38 anti-tank 70-mm missiles.

Bullet-proof glass protects the pilot's cockpit and weapons officer station, internal avionics have been revamped with the addition of a GPS and receiver in the nose, and a warning radar attached to the rear, with four antennae providing 360 degrees coverage and all electronics systems integrated.debkafile's intelligence sources note that the Iranian Air Force's Badr Base for light aircraft and helicopters in Esfahan, central Iran, accommodates 1,000 aerial military vehicles of different types, and is the biggest air base of its kind in the Middle East and Southwest Asia.

The Badr airbase is huge. There are also some Mushak trainers with some Cessnas as well used for training future Sepah airforce pilots . Havanirooz and Sepah Airforce both are active there. Havanirooz Builds spare parts and maintains her fleet there.

You must be kidding... LOL

You know very well that Israel wants to use Iran to black mail the U.S.... so what

Israel also says Iran is building a Nuke... maybe we should all listen to that as well??

[Mr.Jo]

Also tufon's capabilities are not the Issue the real issue is that the Tufon is only an overhaul / upgrad program & that they were not produced in Iran

Chinese copied MiG-19 and Mig-21 and renamed them F-6 & F-7. Manufacturing means manufacturing. Iran has the capacity to manufacture every part for the Cobra gunship and several other Helicopters.

I don't think that anyone would argue whether this a copy of Cobra or not. Question is; are they 100% Iranian, 80% Iranian or less, and what improvements are made.

Go back & look at the pictures

These are overhauld cobras not Iranian cobras

You don't paint only parts of a new Aircraft

You don't equip some with old guns & some with new on a brand new attack helicopter

You don't build an old style cockpit in a new Aircrat you just manufactured from scratch when you have the tehcnology to put MFD standerd euiped in the cockpit & specially since you have done it in the past

unlike the HESA P-4 the Tufon was not produced in Iran

This was a photo up staged by IRI. we already know that. But even as an overhaul and upgrade, a good part of these helicopters are made from Iranian parts.

Bringing available airframce back to active duty should be the number 1 priority before designing and building a new one. Basically, I don't care if every part has a made in iran stamp on it or not, as long as the helicopter force has the numbers that it needs, I am happy.

Arri,
I am not arguing that, all I am saying is that some Iranians here appear to be confused about what their own news tell them regarding their industries military products.
If you would have read my post then you would have read that I said upgrading is nothing to be ashamed of and that all nations do it. As a matter of fact a crap load of our gear over here is all reconditioned stuff. many nations have started their military industries by upgrading their equipment, an example can be Israel, Chile, South Africa, Taiwan etc.... it is a starting point from where others have moved to design and production of their won products.

[yaghoot]

Even if they werent made in Iran, The upgrades were done in Iran meaning we can upgrade almost all the other exsisting fleet. Thats pretty good news to me.

Yes many of the parts are 100% Iranian
Yes It's important to maintain & upgrade our current fleet

but lieing about it just makes us look weak & it's an insult to all Iranians

thank god we increased out defense budget this year.... It took Ahmadi 5 years to realize the importance of spending money on defence
I just hope we don't end up paying for it in the long run
