Am unable to find the link for BRF dictionary. Is the site down? Can someone please post a link here.
Thanks!

Guys, the luh will be purchased by the 100s. Don't get too anxious about that. The machine achieved IOC inspite of the tail rotor vibrations. That has now been fixed. It will be the next Chetak. All rotors vibrate, there were no problematic tail rotor vibrations. The TR blade was modified for addit...

The engine cowling opens downwards to become a platform for maintenance personnel to stand and work in the field. It is the same for the LUH too, because access to the UCS and TX system is a critical aspect of DI and we cannot expect elaborate facilities in the field, so cowlings are designed to ca...

Why would you need ATGM launchers for a medium lift helo. This will be approximately in the same weight class as the Mi-17. There is no need for either the IA or the IAF to be arming these with ATGM's when they can easily buy as many LCH and Rudra as they require. The armed Mi-17's of Kargil came a...

Ahuja sir, I have a question. In your analysis, have the blade properties of individual helicopters been considered? I'm not questioning your analysis but was just curious to know the methodology. Thank you and I really loved your analyses.

While there may be genuine difficulties, for HAL not to be able to get its act together after 2-3 months of Covid downtime while disappointing is indeed not uncommon. Look at their track record, each and every project even where they have been doing the same things over multiple years is always bey...

I dont think the tender should be cancelled. Let Naval Dhruv also participate and prove itself. If it meets the specs, take it. Eitherway HAL should also be asked to provide a guaranteed uptime and also a safety guarantee (the Naval guys are justifiably upset at their Gen1 machines) and focus shoul...

Both CG and IN have taken 32 nos naval Dhruv manual main rotor folding version. If it is not possible to fold at sea why would they take it. The 111 nos NUH tender is for manual folding. To fold 4 blades of LUH takes 10 minutes. To fold just two blades should take 5 minutes. If IN wants they can ha...

It's the same with many foreign helicopters and systems too. They are excellent and unbeatable in brochures

I have never really understood why these and the Chinooks are flown to & assembled in Hindon AFB. Why are these choppers not first flown to the B'lore HAL helicopter division, assembled, flight-tested and THEN handed over to the IA & IAF? I guess we dont want people of different nationality...

IIRC India and Israel have been working already on a uav cheetah for the Indian Navy since 2008. It's still not flown afaik suggesting that such things are not so easy in combat conditions. As such this does not obviate the need for manned 5 gen fighters. The NRUAV never took off. It has been broug...

Shakti does have HAL designed components. Not significant but it exists nevertheless and with the Shakti experience we are moving ahead with the HTSE 1200. Again I'm not saying that TOT from Shakti has enabled it, but just that the minor design contribution and experience with fixing issues has give...

will we export the same version as IAF? Or will there be an export version, that if compromised, will not compromise IAF's LCA More than tech compromises, we should be more worried about the product support mess that HAL will invariably create. We all know what happened with Ecuador. We can live wi...

You're wrong. ALH can fold all 4 blades but the folded dimensions are higher in this configuration. In a 3 blades folded configuration, the folded dimensions are within the helicopter's width. With 3 blades folded and and the tail boom folded, the dimensions are well within the customer specified d...

As i said ALH can fold only 3 of it's blades.. NOT the 4th one. It is no use able to fold only 3. It is actually a waste of resources trying to create another heli maker in India. The NUH should be brought off the shelf, if HAL cannot fold the 4th blade. You're wrong. ALH can fold all 4 blades but ...

F35 is truly a video game. I am pretty sure, IAF will ask for such lazy flying in AMCA. vGU3noa1PEU ACAH with auto trim is pretty common even in airliners. I frankly don't find the control system that advanced and even the LCA can be flown that way. With respect to the weapons and engagement sequen...

I dont think it is an issue of foreign trips and kickbacks but simply that HAL tries to always go for easy, proven solutions where their development team has it easy. This is a vice or virtue (depending on how you look at it, from indigenization or customer timeline perspective) common to several D...

Cross post from the IN ASW and AEW thread. https://hal-india.co.in/HAL%20Delivers%20Ch/ND__265 It seems the 8 new built chetak are only for utility role and not the Match variant for ASW role. Wasn't there a report saying that HAL did not have sufficient blades to service the existing Cheetah and C...

1 and 2, I cannot comment, 3 yes very much, 4 the rotors are not hingeless on the IMRH, 5 BERP is just but one of the tip shapes and our tip shape meets the speed requirement set by the services.

The "why" is the deeper design experience that you can never gain by assembly or building the airframe. It's about why you designed a certain thing in a particular way. Why helps define specs, select and develop materials for a specific application and drives the design of the aircraft. I...

The main rotors are also smaller in size along with fuselage for naval version with lower altitude ceiling of 4.5 Km optimized for naval operations. The dynamic system(rotor and transmission) is same for both versions barring the blade folding system. The lower altitude ceiling does not mean the he...

Please elaborate what this "why" is. Riveting structural components is not making helicopters. I have nothing against anyone who builds them but helicopter Design and development is much more than that and I'm convinced that only HAL has that capability and know how. I am looking forward t...

A simple Google search on the development cost of a comparable medium lift helicopter would have shown that the development cost of IMRH is very low and the second point here is that IMRH is effectively two helicopters in one project. A dedicated Naval variant which again has 3 sub variants and an A...

Is the Mk1A worth it at a quoted price of nearly Rs485 Cr? It’s a combination of 4.5 gen avionics, radar, EW and communications with a 3rd generation payload and endurance! Unless HAL figures out a way to drop the cost to around Rs.325/350 Cr doubt the IAF will bite, and they should not! If the MK1...

A new MGB is almost a new helicopter. And it really doesn't make economic sense to Design test and operationalize one for minor performance benefits given the numbers. Its better to build a bigger heli optimised for sea level ops which is what the NMRH or the IMRH-Navy is.
