- Hindustan Jet Trainer-36 Sitara
The HJT-36 is a subsonic intermediate trainer jet designed and developed by HAL’s Aircraft Research & Development Centre (ARDC). It is a conventional jet trainer with low swept wings and small air intakes for the engine on either side of its fuselage.
The HJT-36 has a conventional tandem two-seat configuration with the trainee pilot forward and the instructor in the raised seat to the rear. The single-piece canopy gives both pilots good, all-round vision.
The trainer features both conventional and manual flight controls to pilots. It features full glass cockpit with a layout similar to current generation combat aircraft. The trainer features an integrated digital avionics system from GE Aviation Systems and Head-up display and repeater from Elbit Systems.
HJT-36: Performance
IJT is powered by Russian AL 55i NPO Saturn Jet Engine produced in house at Engine Division Koraput of HAL. The engine can generate thrust of 17KN. It helps the trainer to achieve a maximum speed of mach 0.75 and g limit of +7/-2.5. HJT-36 has a thrust to weight ration greater than 5.
HJT-36: Weapons
Besides training, the HJT-36 can also be used for light strike or armed reconnaissance role. It has impressive five external hardpoints for weapons training. There is one centerline hardpoint under the fuselage and two-weapon pylons under each wing for carrying rockets, gun pods, and bombs. The maximum external payload is 1,000 kg.
Issues with IJT Sitara
HAL started design work on an intermediate jet trainer in 1997 as a successor to HJT-16 Kiran. Two years later, HAL was awarded a contract for the development, testing, and certification of two prototype IJT aircraft. The first and second prototypes of the HJT-36 flew on 7 March 2003 and in March 2004, respectively.
Long Road Ahead
The development of indigenous IJT was not a smooth sail and was full of roller coaster ride.
The program faced delay by two years due to the late delivery of NPO Saturn engine. Later, two accidents in February 2007 and in February 2009 involving each of the prototypes grounded the aircrafts for repairs and investigations.
After further development and extensive testing, the Indian Air Force placed an order for 73 aircraft. The aircraft entered limited series production in 2009 for the first 12 aircraft. The IJT has already completed sea level trials, night flying trials, high altitude trials as well as weapon and drop tank trials. However, in order to receive the FOC, the trainer was to demonstrate stall characteristics, and spin testing.
In 2016, the IJT program almost stalled over the prototype’s unsatisfactory spin testing characteristics when the aircraft departed from controlled flight. The issues were linked to the platform's critical stall and spin characteristics to provide trainee pilots with greater manoeuvrability to the aircraft. The IJT Sitara was to remain "unfit" for service as an intermediate jet trainer (IJT) until these issues were resolved.
Rise of Phoenix
HAL had to resort to major modifications in the aircraft like shifting the vertical tail aft on the airframe and increasing the rudder area to correct its spin characteristics. In April 2019, Sitara flew for the first time in three years with a modified air frame.
On 6th January 2022, the IJT has successfully demonstrated the capability to carry out six turn spins to both the left- and right-hand sides. With this milestone achieved, now the aircraft will go for certification. HAL performed several test flights before carrying out the 6-turn spin flights, marking the beginning of a resolution to a problem that plagued the programme since 2016. As per HAL, the aircraft will require another two years of testing after which it will be ready for induction.

Sitara looking so cute, ❤️.. Hope that she will over come all technical issues and become the trusted and zero crash jet trainer
Great plane. It has 2.5 decades of development experience
Don't blame HAL for it ! Blame khangress bcoz instead of focusing on Nations Defense it was busy appeasing minorities!! Khangress govt financial record is abysmal. They never had enough money to give for defence projects, No competitive attitude by PSU's during there tenure. Plus, India had way more hurdles 2 decades back then we have now !! It's easy to bark sitting in your own home.
Indian Air Force should induct HTT-40, HJT-36 and HLFT-42 Trainer Aircrafts in good numbers. This will also helps in increasing their Exports and we can also give good Competition to other Countries like Brazil, China, Italy, Russia, South Korea, UK, US who are earning good Revenue by Exporting their Trainer Aircrafts.
They are yet to enter the IAF, yet to prove that they are reliable trainers,yet to prove a lot of things. And you are talking about exports ! Other countries are not mad to buy such untested aircraft. A foreign country will buy an aircraft , only after it has been in use in the home country for at least 3-4 years without problems. Seedha export !!! Bhai wah !!!
@@siddharthshekhar909 Abey Dhakhan why your Ass is Burning???? India is developing all these Trainer Aircrafts by keeping in mind of Exports. All these Trainer Aircrafts will be of High Quality but Gaandus like you are busy Portraying Indian Made Weapons as Useless. Grow Up
@@siddharthshekhar909 why Spain order aircraft even aircraft made design
HTT-40 got the order of 70
@@fly463 A 10 how much old
Beautiful aircraft. Hopefully it is ordered soon.
First it has to be ready still 2-3 years away
HTT40
HJT36
HLFT42
😍
It can be waponised ans sold to some countries
If the sitara finally completes the trials in 2 years time, the HTT-40 and the Tejas
lift trainer will already be in service. Once again training will be done on fully indigenous
planes!
This also opens the doors to valuable exports. Would like to see replacement of these
foreign parts
Digital avionics system from GE Aviation Systems
Head-up display and repeater from Elbit Systems.
Tejas already has indigenous systems that can do the job. Should be simple
task to replace them.
Russian AL 55i NPO Saturn Jet Engine - The Kaveri is a much bigger
heavier engine than this one.
Kavero
Length: 3,490.0 mm
Diameter: 909.3 mm
Dry weight: 1,236 kg
Military thrust: 52 kN
AL 55i Saturn
1,950 mm
Diameter: 590 mm
Dry weight: 315 kg
Maximum thrust: 17.3 kN;
Shrinking the Kaveri to 1/3rd the size should yield an engine that performs on par or
better and weighs the same,.
If wishes were horses! I would love to shrink INS Vikramaditya's engine to fit in my car!
@@kurroth Fuel economy would be terrible. Get a fuel cell or EV kit they can be put into regular cars and you get better fuel economy.
Why wish thinking? HTT40 and LCA lift are already induction/late stages of production.
Only Sitara is two years away.
Do we manufacture all spares in house for the Russian engine in the jet, or do we have to import them?
Russians never allow us to set up complete production line of their weapon system or engine in India. they always keep some of the key parts of it under their control which we need to purchase from them.
.So that they can squeez us anytime at their will.
आत्मनिर्भर भारत is the only and only solution to overcome all these problems. nothing else.
जय भारत.!! जय मोदीजी !!!
HTT 40 is replacement of basis trainer HJT 36 replacement of medium trainer HLFT is fore higher
Will Hal replace Russian engine of hjt36 by htfe25 ?
Is it in hawk category
Hawk comes at level-III of training, this one is at level-II
once IAF inducts it after all the required testing, it will have a huge export potential..
Bro,
Can HLFT 42 replace Hawk
Absolutely!!
as claimed the IAF will take another 2 years to conduct tests of spin and stall before awarding FOC to HJT-36 Sitara which would give way to its full production.
It means that we shouldn't expect the first Sitara IJT before 2026-27 if everything goes okay from hence.
won’ t it be an outdated aircraft by then ?
IAF is still flying 50yrs old Kiran, so it wont be IJT is an excellent platform.
Trainer aircrafts lasts well over 30 years and their technology is not as bleeding edge like fighters. We are using Kiran aircraft which is a 50 year old design. PC-7 aircraft used for basic training is also 50 year old design upgraded with modern avionics
Thrust to weight ratio greater than 5? How?
Ah I think I said it for aircraft which is wrong. It's the thrust to weight ratio of AL 55i "NPO Saturn Turbo Fan engine which powers the aircraft. Thanks for pointing it out.
@@IndianDefenseAnalysis that makes sense. Keep up the good work.
🇮🇳🇮🇳✌️🇮🇳🇮🇳
Proud of India for developing its own trainer jets! However, can we trust Russian engines, that too a single one? I wish the jet looked sleeker but as long as it functional it does not matter!
Sir any idea
If the deal for additional 2 phalcon awacs has gotten through or has it been placed
It's in negative list so can't be imported
Ok thank you
PhysicsOnLine
Shouldn't take so long to develop a trainer; particularly one to replace your owb earlier manufacture. Spmeone took his eye off the ball.
🌀⚔️☠️🌍☠️⚔️🌀✌️
Sir
How beneficial would bomber aircrafts be,
Is it the payload they carry,
How can range be an advantage,
because without entering a contested airspace,
A bomber launching a missile and land based launcher launching a missile, aren’t they the same
Within our borders
Bro can IAF trainers like HJT-36, Hawk I, HTT-40 be turned into UCAV ?
Yes
@John Hero why not ?
@John Hero i see, thanks for the insight, do u know any update on the armed Heron TP program ?
@John Hero HAL is working on it
@John Hero not Mig, I am trying to search my record for it, will share once I have it. It was Hawk as per my memory.
