1 ton payload capability at 4.5 km altitude is good.
How much Mi -7 v can carry?

I doubt it can carry any meaningful loads at 4.5 km altitude. Haven't seen any Mi17 operating to Siachen base camp helipad or to Daulat Beg OldieHow much Mi -7 v can carry?
That's because of the rotor length requirement came from high altitude performance. Cabin size would be normal i imagine.HAL's IMRH seems to be the largest helicopter in its category. Most other helicopters are coming at a maximum length of around 20m but IMRH goes around ~25m.
Won't the size have any effect on naval variant?That's because of the rotor length requirement came from high altitude performance. Cabin size would be normal i imagine.
It will be different rotor design.Won't the size have any effect on naval variant?
Design and performance goals
In addition to 3,000-shp output, the targets for AATE were a 25% reduction in fuel consumption (less than 0.347 lb/(hp⋅h), 211 g/kWh), a 65% improvement in power to weight (more than 6.5 hp/lb, 10.7 kW/kg), a 20% improvement in design life (more than 6000 hours and 15000 cycles), a 35% reduction in production (less than $650k per engine) and maintenance cost, and a 15% reduction in product development cost. The 3,000-shp goal for AATE is a 50% increase over the most powerful T700-701D variant, but would also require upgrades to gearbox, transmission, rotor blades, and tail rotor.
Both the ATEC and GE designs can start without an auxiliary power unit (APU), using the battery alone. The UH-60 and AH-64 are currently equipped with Honeywell GTCP 36-150 APUs.
Using ITEP, the combat radius is projected to increase by 500 km (270 nmi). The hot and high service ceiling will be increased from 4,000 to 6,000 ft (1,200 to 1,800 m) at 95 °F (35 °C). Performance targets have been determined in part by operations in Afghanistan and Iraq, as well as growing airframe weights.
IMO, joining the US side always comes with some major perks. Those who are using BlackHawk and Apache will continue to do so and replace with what US beings to the table. As was seen in case of Aussi they replaced all of their Tigers with Apache instead of the upgrading them.
So, IMRH engine (HAL-Safran JV) will be clean sheet. I didnt expect this !.
I feel like in the long run it will be a more impactful partnership than AMCA engine or GE414 partnership.
In the 3,000 shp market it will have to compete with GE T901. It was developed under Improved Turbine Engine Program (ITEP). It is the replacement engine for Apache and Blackhawk. Also, for the US Army Future Attack Reconnaissance Aircraft (FARA) program.
If they could active these goal, then there is nothing like it. Is it too much to ask?

If its a cleansheet engine how can it start production in 4 years? Maybe he meant prototype production.What is the status of the joint venture to design and develop helicopter engines with Safran?
The JV will become operational next month, and production of engines is expected to begin in four years. These engines will be for the Indian multi-role helicopter (IMRH) and its deck-based version. There is a requirement for around 400 such helicopters. We are looking at basing the Safran-HAL JV at our new Tumakuru facility, which is the largest helicopter manufacturing facility in the country. We can manufacture up to 90 helicopters in Tumakuru every year, a mix of LCH, light utility helicopters and IMRH. With the JV based there, Tumakuru will become one big complex for helicopters and associated equipment. Safran and HAL will have a 50:50 work-share. IMRH could go into production with the new engine by 2031. The timelines are tight, but the good part is that we are already manufacturing the Shakti engine for the advanced light helicopter with technology transfer from Safran.
