"Jahesh-700", Iran's first turbofan engine

[mohsen]

Jahesh-700 (Leap-700) is Iran's first turbofan engine, which incorporates cutting edge single-crystal blades technology. defense minister described it similar to engine of drones used in advanced countries including the RQ-170 which was captured by Iran in 2011.

This engine has 700kg thrust and can be installed on planes with up to 4000 kg weight. it increases the flight ceiling of Iranian drones to 60000ft.

Jahesh is modular, has advanced control system, has very long TBO (time between overhaul) and very low fuel consumption which gives the long flight endurance to our drones.

A very significant development. This is indeed generations ahead compared to Iran's previous jet engines. What this highlights is that Iran is more ahead in this very difficult sector than we had thought.

Now we can expect the arrival of next generation UCAVs in Iran.

is it ok if i copy that?

 

[Imran Khan]

it can be used for drones only . even light trainers like k-8 have 3500 to 4700 LBF engines

Just a fact: The fuel consumption per kg thrust of this new engine is half of that of a Owj/J-85 --> twice more efficient --> twice range/flighttime.

The more the better!

It feels like our first steps with Scud missiles in 90s ... wish to see advanced Iranian-made heavy fighter jets ... we produce everything so cheap with high quality ... if China helps us we can do it faster ...

3500 to 4700 LBF

3500-4700 lbf=1575-2115 kgf. two of these engines can power a plane with ~4000 kg take off weight.

and some big cruise missiles too , but if Iran add 4 of this bad boy on a large stealth drone the maximum takeoff weight of the drone would be 16000 kg that mean at least 5-10, 2000-3000 km cruise missile or about 200 - 250 Iranian sadid smart bombs.

Just a fact: The fuel consumption per kg thrust of this new engine is half of that of a Owj/J-85 --> twice more efficient --> twice range/flighttime.

so it's specific fuel consumption is around 0.5 lb/lbf*h??
that means for an hour of full thrust flight it will use ~350 kg of fuel, impressive.

 

[triangle]

the payload capacity of the drone would be 16000 kg

No, not payload capacity but MTOW

 

[PeeD]

In the IRGC version for Simorgh, it will add a electrofan which provides additional thrust and increased fuel efficiency.

 

[skyshadow]

No, not payload capacity but MTOW

you are right, it still can carry up to at less 3-4 of those cruise missiles with that maximum takeoff weight

How much % extra thrust can one expect in this case?
