So, on which day are you planning to visit the Expo ? I might be there on 13th /14th.
Mods - any BRF meet on the sidelines ? Do we have a stall for ourselves ? Like we had at AI, many moons ago.

Bob V

I guess its the same procedure when visiting any restricted area. Bring your Govt. IDs, no bags/food/water bottles, no phones etc. What I am concerned about, is the exact location where these ships are berthed & how to reach there ? I have been to the port only once & that too, only to the c...

Bob V

Had done so, a couple of days back. They don't even bother to reply. Have noticed several people on twitter posting similar questions to their handle but haven't seen a single response to them. Typical sarkari mentality in this age of SM.

Bob V

I did check that but they update the info only on the vessels which are berthed on that particular day or are planning to berth.

Bob V

I can't seem to find any reference online regarding the terms & conditions for the port visit. No mention anywhere of the exact pier/pontoon where these are docked & how to reach that location ? What type of permissions are required ? What kind of IDs are accepted for verification ? Whether ...

Where did you get this picture from ?

Oops! Just realized that you are not visiting both the events on the same day. My bad!

Bob V

whoa! that's good. Atleast there's a full blooded frigate on show but why no destroyer :cry: Btw, make sure you plan properly because the Exhibition ground & the Port are on the opposite ends of the city; would take a solid 1 hour to travel, not counting the weekend traffic. Expo opens at 9am, I...

It appears that there is a Delhi/Kolkata class destroyer, anchored off Marina, right now. My eyesight is poor but that's what I could make out, during my morning run. Look at the center of the pic below - https://imgur.com/a/kQvzZ Wish they would allow civvies for a quick visit onboard. I have never...

I thought it was a much better broadcast from DD. The cameras tracked the vehicle well during lift off and initial phase of flight, without losing sight of the vehicle as happened during some earlier launch coverage's. Also the resolution of the video seemed to be better (HD?). Yep. The camera trac...

Bob V

low-level clouds hampered any chances of taking good shots. I was waiting with my tele-photo lens, on the terrace.

Bob V

Looks like its highly unlikely that i'll be able to make it to the Defexpo.Just too far out of town.Madras ,sorry,this is new extended Chennai,traffic is a b*tch.Hate it.Plus the weather there is going to be roasting hot. Hotels nearby would've all been filled up.so too the clubs. Sir, Chennai is n...

Bob V

And I am barred, but here's my solution. Explosive charge at rotor hub triggered during ejection sequence to separate the rotors a second before ejection seat fires. Similar to line charges for shattering the canopy. That is the most commonly thought out solution. I think Ka-50 had tried to/has imp...

Bob V

What was the name of that Russian ship, which had first implemented this concept & was discovered subsequently by the US intelligence ? I can't seem to find any reference of it, on the internet.

Bob V

Are those bow thrusters on that OPV, a new feature on locally designed boats ? I haven't seen anything similar on our bigger boats. Although it's a cold war concept & was successfully used with cruisers then, it is still relevant today

Bob V

Did anyone discuss here regarding the weight reduction initiatives, undertaken on Arjun, especially the plans to introduce carbon-fibre based wheels ? Would it lead to a significant reduction in the tonnage ?

Bob V

Yep. Was about to post it here. Looks like a great opportunity for final year engineering students/ those looking for internships in DPSUs.
The first 2 challenges are rudimentary; solutions for these have already been developed by other nations/aviation conglomerates.

She survived the hard landing but was hit on the back of the head by the slow moving rotor blade, when she stepped out.

^^This is the first year and the novelty may not have caught on. Gen visitor pass may work IMHO Alright. But the last expo I visited was the DRDO exhibition at HVF Avadi, last year. There was a mad rush on the last day, with local folks coming over & kids running around. It resembled more like ...

Bob V

I'll be visiting the expo, just to gaze at the mechanical monsters. Is it worth taking a Business Pass for that or will a General visitor pass be enough ? Also are there any restrictions on the movement/visibility to the displays, for General visitor pass holders ? I understand visitors are allowed ...

Bob V

Is there a thread to discuss the upcoming Defence Expo ?

Bob V

It seems that the Reliance 2G & 4G networks are down, across several cities. There was no prior intimation & the service disruption was abrupt. Anybody knows the reason behind this ? I heard that they were planning to phase out 2G services, due to stiff competition, by Nov 30 ( inspite of th...

Bob V

Although this is a great achievement for his team, but is this the very first time someone has built an experimental aircraft in India ? I know there are few amateur aircraft associations in India, like Intermeridian & they usually assemble 2 seaters from kits (4/6 cylinder, prop based ones). Pe...

Bob V

Good effort. But did his team actually manufacture the parts or is their role limited to just assembling the a/c ? LG & props seem to be off-the-shelf. There's no mention anywhere, of the type of powerplant being used. The fuselage shape looks a bit odd, especially the mainplane roots. Overall, ...

"SC: Engineering degrees secured since 2001 via correspondence invalid" That's a poor judgement. The judge seems to have failed to understand the difference between a degree obtained via Distance Mode ( while attending classes at a study centre ) & those via correspondence. I have wor...

Government to frame rules for civilian drone use

Better late than never !

Bob V

Well, I can attest that adherence to quality & testing of components was mandatory, till a few years ago - experimental or not. The inspectors were hard-nosed ones & were stickler for the rules. You couldn't fool them by passing off auto parts for aviation purposes. A simple example - I trie...

^^There are indeed cities like that. I grew up in a Tier III city in N.India & we had all those amenities as mentioned above, since early 80s : wide roads & well-planned layouts, road maintenance done every 2 yrs irrespective of the road's condition (2 layer tarring - bitumen followed by san...

Bob V

before we condemn our babus, I'm not sure if a technologically sound and safe aircraft can be built on someone's terrace. I doubt the journalist has the slightest idea what is takes to build an aircraft. I'm surprised no one is discussing this, on the forum. How do you even manage to build a full s...

Mi-17 helicopter crash-lands in Uttarakhand

Bob V

Yes, infact such a concept was indeed put into practice. The system was called NOTAR . I guess McDonnell Douglas played around with this concept in the late 80's or early 90's & I think they were quite successful with it. I had seen the civilian versions of it more than a decade ago, not sure if...

The fuel tank is located under the cabin floor but the fuel dump system is not prominently visible from outside. The protruding pipe that you see, is part of the drainage system, connected to the cabin floor to ensure it remains clean, all the time (I'm now 400% sure).

Bob V

(2) is HF antenna....take it FWIW, coz I usually have an upper hand on these matters

Bob V

(1) Not exactly sure, but I remember it to be a basic drainage line connected to the cabin floor OR maybe I'm mixing things up & it might be part of the fuel dump system.
(2) It is the HF antenna.
(3) What light blue? where ? Are you talking about the tail rotor ?

Bob V

NAAARMAL so far.

Happy Independence Day !

BRF is back !....AoA...AoA..AK phyrr....RPG phyrr.

The bleed air is derived from the HP compressor section which is just ahead of the combustion chamber.
