Iran claims to have domestically produced drone By ****.***

Tehran announces completion of unmanned aerial vehicle following interception of US drone in December.

Less than four months after confiscating a US drone that went down in its territory, Iran has domestically produced a new unmanned aerial vehicle called the Shaparak (Moth), Iranian state-owned news agency Press TV reported on Saturday.

The drone has an operational radius of 50 kilometers and a flight ceiling of 4,572 meters, Press TV quoted Reza Danandeh Hakamabad, the aeronautics engineer in charge of the project, as saying on Friday.

He added that the aircraft has the capability to fly non-stop for three and a half hours and can carry an 8 kilogram payload.

Powered by a two-cylinder engine, the Iranian drone is equipped with cameras that can submit surveillance images to the base on the ground, according to the report.

Iran claimed to have shot down a RQ-170 Sentinel drone that was flying over its airspace in December, later saying that they had actually commandeered the UAV’s navigation system, making it land in Iranian territory.

US military officials said that the drone went down due to technical difficulties while on a surveillance mission, denying that Iran had actively brought the craft down.

Iran displayed the US drone on television, vowing to “reverse-engineer” the UAV to build its own drone.

Meanhile, the world’s biggest electronic payment system on Saturday cut off Iranian banks blacklisted by the EU, in an attempt to further strangle Tehran’s ability to finance a nuclear program.

Belgium-based SWIFT, which facilitates the bulk of global cross-border payments, said it disconnected designated Iranian financial firms from its messaging system on Saturday after European regulators ordered the company to do so.

“The EU decision forces SWIFT to take action,” Lázaro Campos, SWIFT chief executive, said in a statement on Thursday.

“Disconnecting banks is an extraordinary and unprecedented step for SWIFT,” Campos said. “It is a direct result of international and multilateral action to intensify financial sanctions against Iran.”

با قابليت كنترل ترافيك و امدادرساني

هواپيماي بدون سرنشين سنگين وزن در كشور ساخته شد

محققان تبريزي موفق به طراحي و ساخت هواپيماي بدون سرنشين مدرن و سنگين وزن شدند.

رضا داننده حكم آباد، دانشجوي خلباني سازمان هواپيمايي كشوري در گفت‌وگو با خبرنگار فناوري ايسنا، خاطرنشان كرد: بدنه اين هواپيما كاملا به صورت بومي با استفاده از انواع چوب در تبريز طراحي و ساخته شده است. اين هواپيما از نظر قيمت و هزينه‌هاي پروازي از مشابه‌هاي خارجي خود ارزان‌تر بوده و از مقاومت بالايي برخوردار است.

وي درباره مشخصه‌هاي هواپيماي بدون سرنشين «شاپرك»گفت: طول بال اين هواپيما چهار متر، طول بدنه، 260 سانتي متر و ارتفاع آن 86 سانتي متر است و داراي يك موتور دو زمانه دو سيلندر 116 سي سي است كه بيشينه وزن برخاست اين هواپيما 55 كيلوگرم است.

داننده حكم آباد افزود: اين هواپيما مي‌تواند در باندهاي آسفالت، خاكي، ‌چمن و ... نشست و برخاست كند. سرعت برخاست اين هواپيما از زمين 35 تا30 knot (حدود64 كيلومتر بر ساعت) بوده و سرعت نشست اين هواپيما knot 30 است همچنين داراي سرعت كروز knot 85 معادل 158 كيلومتر بر ساعت و حداكثر سرعت پرواز اين هواپيما knot 130 است.

وي با بيان اينكه اين پرنده توانايي پرواز در هر شرايط آب و هوايي در شب و روز را دارد، تصريح كرد: هواپيماي بدون سرنشين «شاپرك» مي‌تواند تا ارتفاع 15 پا(پنج كيلومتر) اوج بگيرد و برد عملياتي اين هواپيما 50 كيلو متر است و مي‌تواند بدون سوخت گيري به مدت 3.5 ساعت به پرواز خود ادامه دهد.

داننده حكم آباد خاطرنشان كرد: اين هواپيما توانايي حمل بار به ميزان هشت كيلوگرم را دارد و مي‌توان اين هواپيما را در مدت زمان كمتر از 20 دقيقه عملياتي كرد و به پرواز درآورد. يكي از ويژگي‌هاي اين پرنده، قابليت ادامه پرواز با خلبان خودكار (AUTOPILOT) است.

به گفته وي، هواپيما داراي سه دوربين نصب شده در بدنه است كه توانايي همزمان ارسال تصوير به صورت زنده (online) به ايستگاه زميني و ذخيره (save) تصاوير در هواپيما را دارد.

وي ادامه داد: از ديگر توانايي‌هاي قابل توجه اين پرنده مي‌توان به توانايي پرواز در ارتفاع پايين، هزينه پرواز اندك، تعمير و نگهداري سريع و قيمت تمام شده پايين‌ اشاره كرد.

داننده حكم آباد ادامه داد: انجام ماموريت نظامي، حفاظت جنگل و مرزباني، كنترل ترافيك شهري و جاده‌‌يي، استفاده در امداد و نجات، تحت نظر گرفتن و حفاظت از كانال كشي‌هاي نفت، حمل بار، پروازهاي نمايشي و نمادين در جشن‌هاي ملي كشور و تصويربرداري از جمله كاربردهاي اين هواپيماي بدون سرنشين است.

وي در پايان با بيان اينكه اين هواپيماي بدون سرنشين با حمايت معاونت پژوهشي دانشگاه تبريز عملياتي شده است، اظهار اميدواري كرد كه با حمايت‌هاي مالي بتوان هواپيماهاي بسيار مدرن و پيشرفته در سرعتهاي زياد و بردهاي بالا را در كشور ساخت و به توليد انبوه رساند.

به گزارش ايسنا، مهندس محمدرضا سجادي، كارشناسي ارشد مكاترونيك دانشگاه تبريز و مهندس محمدحسين داننده حكم‌آباد، دانشجوي رشته مكانيك دانشگاه آزاد اسلامي تبريز از ديگر اعضاي گروه سازنده هواپيماي بدون سرنشين شاپرك هستند.

jpost is such a bullshit source, they take a BS (at most MS) level university project and announce it as a new military milestone? My God how desperate have they become with their media attack on Iran?

Ayyash · « **Reply #228 on:** March 18, 2012, 05:15:45 PM »

I think a lot of it might come down to mis-perceptions of Iranian media. I doubt JPost has Persian-language experts going over the ISNA version of the article posted above, or doing in-depth research on Iranian UAV projects. Instead they probably just has a staff writer combing wire reports who saw the article by PressTV. In fact, it's specifically referenced as the source for the JPOST article. It doesn't help that PressTV journalistic standards are...lacking to say the least.
http://www.presstv.ir/detail/232095.html

The PressTV article in question doesn't talk about the university research aspect, describes the military potential, and than goes on to talk about other military UAVs. This isn't an excuse for poor intellectual integrity on behalf of JPost, but I think it's a plausible explanation for why the Shaparak was interpreted as a newsworthy development (that, and lack of in-depth technical knowledge about UAVs)

Why most of Iranian drones have a low endurance? Look at these:
Mohajer 1: 45 min Range:Unknown
Mohajer 2: 60 min Range:50 km
Mohajer 3: Unknown (probably 60-90 min) Range:100 km
Ababil: 60-120 min Range:150 km
Saeghe: 45-60 min Range:50 km
Talash:45 min

These are not good. Iran's best UAV (Mohajer 4) has an endurance of 5-7 hours which is still low.

here is some text from the seeker UAV brochure:

.... has a modular all-composite, lowdrag design that ensures optimum performance. The UAV’s highly efficient engine and large fuel capacity provide up to 16 h endurance with extended service intervals. This, combined with a service ceiling of up to 18 000 ft......

So these are the factors... you need to have a light weight + good engine ... if it can fly higher => less drag so more fly time ... you need to have big fuel tanks... the factors are simple .. no magic in there

Sent to me by a reader of the blog, this image (that as far as I know was originally posted by the Iranian site Mashreghnews.ir) is one the few available on the Internet of what should be a Mohajer-3 drone.

Also known as the “Dorna”, Iran’s Mohajer-3 seems to be quite similar to the Mohajer-2. It is a equipped with a forward facing camera, mounted in the front of the fuselage and is believed to be able to carry TV or FLIR cameras in a new payload bay. It carries also a line-scanner that, according to some Iranian websites, is capable of a 1-meter resolution at an altitude of 5 km.

Made-in-Iran Syrian drone dubbed “Pahpad” has been widely employed in Syria but the Assad’s regime against the oppositors. For the moment, in spite of the rumors, no images of other types of drones have emerged.

Well, I think I've found the specification of one of the engines used on Mohajer-4. The one that is more common. It is Limbach L550E. It has a power of 50 hp and is also used on "Pahpad" (aka Seeker 1). Notice the engine on one downed Seeker in Sudan and compare it to Mohajer-4's engine. Exhaust tubes and the overall configuration of these engines match.

If true, you mean it's an Iranian VARIANT of the Limbach L550E, correct? I don't see how this could be a non-Iranian engine for various obvious reasons. Thoughts?

I don't see any reason why would we make this in Iran. There many ways to buy these engines through other countries without notice.

I understand your point and of course it is possible, but it does go against various vectors of Iranian strategy: military self-sufficiency and eliminating reliance for tactical and strategic components, leveraging preexisting industrial capabilities, hedging against future sanctions, and last but not least saving on cash reserves.

If you are correct and these engines are imported I am very surprised.

I don't know does Iran produce Limbach L550E or not, but Iran has announced that produces wankel engines for UAV's.

At least 3 new UAVs in recent wargames:

Seeker 1 (Pahpad)

Mohajer 4

That new drone looks like a smaller version of USA predator!!!

mamdali · « **Reply #241 on:** July 03, 2012, 05:04:01 PM »

These 'new' drones drive the point home: Iran has an unrevealed series of significant capabilities across the board. There is no doubt about it. That is a critical message being delivered with the release of these imagery.

Very interesting indeed! Given that they're all more-or-less in the same class, and bear significant design similarities to other models, but also include equally significant variations, I wouldn't be surprised if these were all test-beds to evaluate specific design features.

The first type with the high-aspect, swept wings also includes the canted tail-boom we've seen on the Sahand and ~~the other one whose name I can never remember~~ the Hodhod. Then there's another one with a similarly skinny body, and high-aspect wings, but with two vertical-stabilizers attached directly to the fuselage and canted in the opposite direction as the boom-equipped one. Neither of these two types appear to have any landing gear; the second type is being launched by RATO.

The third type has a cigarette fuselage combined with the "Reaper" vertical-stabilizers. Unlike the first two, this model has tricycle landing gear and straight wings (though still high-aspect). It's gray color is rather unique, maybe some sort of low-visibility scheme? It's carrying something under its fuselage, but it's difficult to tell what. Assuming the landing gear is the same size as the set used by the other model in the video it's probably relatively large as far as Iranian UAVs go.

The fourth type, the other model with tricycle landing gear, looks a fair bit like Pahpad (aka the Seeker) with it's high wing and basic fuselage shape. The nose and landing gear are different, but the tail section has been redesigned with the same type of canted stabilizers used in the second, third,and fifth types.

The fifth and final version is by far the most interesting because it doesn't use the cigarette or square fuselages that are typically used in Iranian drones, but instead has a low-profile spade shaped nose. This model also has the gray paint-scheme, and canted stabilizers mentioned above. Same type of skids as on the Mohajer-4.

Is it only me or this drone is really bigger than anything Iran has produced till now?

Look at the camera, compare its size to the size of other drones.

Someone in militaryphotos mentioned that it is very similar to Hermes 450. Probably these drones are Iranian versions of the US drones downed (remember that they said they showed Iranian copies to the Russians?).

Anyway, Hermes 450 uses a Wankel engine, and as M-ATF said, Iran announced that it is going to produce Wankel engines for UAVs. Hermes 450 is a good UAV. Almost better than anything Iran has. Hope to see more of it soon.

You can easily identify stealth characteristics by geometry: triangle fuselage cross section, V or inverted V shape fins, parallel leading edge/trailing edge of wings

Catsoo · « **Reply #245 on:** July 04, 2012, 07:31:44 AM »

Te first photo seems to me to be a flat shaped fuselage rather than a triangle one. The combination of the V-tail and the fuselage characteristics seem to be for stealth or low RCS signature. But I would say these new UAV's are prototypes and we have yet to see a final design.

Some people are speculating that this is a evolution of the "Shir Dal" uav project:

http://www.uasvision.com/2011/11/22/another-domestic-iranian-uas/

But I think that is rather unlikely.

The frame, wings and propeller also do not look very similar to that of the Hermes 450 .
