This is what Harry mentioned:

HAL HTT-35

HTT-35 is designed to meet the IAF Air Staff Target 208. This details a replacement for both HPT-32 and HJT-16, inferring a requirement for more than 150 aircraft.

Unveiled in mockup form at Avia India 93 (Dec 1993), the HTT-35 is a conventional looking tandem seat low-wing monoplane, with a distinctively hump backed appearance and stepped cockpit covered by separate upward hinging canopies. The retractable tri-cycle undercarriage retracts inwards (main units) and rearwards (nose gear). The pilots will sit on lightweight ejection seats.

HAL hopes to use either the 1150 SHP Garrett TPE-331-12D (flat rated to 11 SHP / 819 KW) or the 1150 SHP P&W Canada PT6A-62 (flat rated to 950 SHP / 707 KW) to power the new aircraft.

Full scale development awaits a government nod, which HAL hopes to receive by Mid-94, leading to the first flight 24 months later.

Performance:

HAL claims a maximum level speed of 290 mph (470 kmph) at Sea Level with a stall speed in approach configuration of 80 mph (127 kmph).

The Take-Off to 50 ft (15 m) is 850 ft (260 m) and landing distance from 50 ft is 1900 ft (580 m). The sea level rate of climb is calculated as 4000 ft (1220 m) per minute, and service ceiling as 29,500 ft (9000 m).

The HTT-35 will be fully aerobatic, with a normal operating load factor of +6 to –3.8 and a fatigue life of 7000 flying hrs.

Weights:

The integral wing and fuselage tanks will carry 450 kg of fuel, with an inverted system allowing upto 30 s inverted flight. This gives a range of 790 miles (1270 km) and allows two high-density aerobatic/spinning sorties to be flown on a single load of fuel.

Underwing hardpoints (stressed for loads of up to 250 kg each allow the carriage of bombs, gun or rocket pods for weapons training of CI duty.

The Su-27M (T10M-3 or Su-35 no 703) featured new wing panels with bigger fuel cells and increased area fins with internal fuel cells. This resulted in an increased fuel capacity by nearly a ton to a total of 10,250 kg. This was done to compensate for the heavier airframe (canards) which would have led to a decrease in range. Not this is a bird with conventional AL-31 engine.

….

The MKK has ‘borrowed’ the Su-35 tail fins. But Fomin book say that the internal fuel laods of the Su-35, MKI and MKK are 10,250, 10,000 and 9,400 kgs respectively. But they carry same max warload and MKI and MKK have a slightly shorter range at high alt and sea level when compared with the Su-35 (note NOT the UB just the single seater).

Doesnt the MKI contain an ‘insert’ at the base of the moving rudder in the fin that correspondingly increases the height of the fin? :confused:

I still say that they (india) should retain some of the Su-30K/MKs for an exclusive agressor task 😎

The HAL Sus will be a lot cheaper to manufacture, but the balance would be compensated by royalties that have to be paid to Irkut. HAL

HAL chairman Nalini Ranjan Mohanty has said that the Indian-built Su-30s will cost only about $22.5 million a unit against the current import price of about $37.5 million [Financial Express, 10-Dec-2001].
