Varoon Shekhar wrote:Not sure if anyone mentioned this, but Claude Arpi, who normally writes sensibly, and is sympathetic to India, made an awfully sweeping dismissal of DRDO in his rediff.com article. He said they were essentially good for building bio-toilets. After all that has been accomplished, including most recently with the Sagarika series, how can anyone sweepingly denounce DRDO?

Arpi in his feature on Aero-India is really plumbing for the Rafale, and calling for private sector involvement in defense development. But it's one thing to advocate private sector participation in armaments manufacture, quite another to be blind to the real achievements of a government/public sector organisation. Don't let your feelings/prejudices on the public vs private sector issue, get in the way of acknowledging facts and visible achievements(Agni 5, AAD, K-15 et al).
That is why one must take any and every analysis of India from foreigners with a sackful of salt.

No,they do offer valuable insights into their objectives.If you read between the lines you often find what they want India to do in their own selfish interests.

Absolutely correct. We just need to know and be aware. The French, for instance, like to have people long term. True believers as it were. They understand that Indians, after a long time, simply accept and absorb, and even give equal (sometimes more) status/standing to someone who is not one of them. They are not the kind who will not utilise that exploit. We just need to be aware, observe.

Someone was looking for my post about single crystal bade from DMRL

Single crystal turbine blade story.

The gentleman from DMRL was very friendly and informative

1.The image below shows the development of tech (in SDREland) from plain casting (labelled equaxed), to "dirtectionally solidified" to single crystal.
Image


2. The image below is of examples of blades made by the three methods mentioned above
Image


3. For single crystal blades to have a hollow honeycomb interior, a ceramic core is used around which the crystals are grown. The core is leached off later. The image below shows ceramic cores with the hollow part of a blade visible.
Image


4. Here is a fully formed blade - the extra spiral bits needed for manufacture will be removed for finishing the blade.
Image


5. From the HAL stall - a single crystal blade used in Al 31

Thanks Shiv - so does HAL have tech to make SCB or is it just again screw driver technology. I am surprised SCB was not used in Kaveri.

Shiv Sir: thanks very much for sharing the Single Crystal pictures from DMRL and HAL. Did you get a chance to ask them if we are ready to mass-produce this? And whether the temperature resistance of the homegrown SC blades meet the requirements of an engine if we were to build a F404/414 equivalent?

The DMRL man said that their role is to develop the tech and hand it to anyone who needs it. He specifically named Kaveri. Later I was surprised to see a similar looking single crystal blade from HAL engines divn. I was unable to ask if this was via Russia or DMRL.

Must be from the Russians, must be from HAL Koraput for the Al-31. AFAIK SCB from DMRL tech hasn't yet been manufacture by HAL Koraput although tech to setup the production facility to do so has been transferred.

Exactly those were my thoughts

Displaying cores and some castings does not mean they have been adapted to manufacture in large scale and with acceptable quality.

The ceramic core is understandable, but why not ceramic coat itself?

Neat shot SagarAg! Both the indigenous fighter and helicopter in a single frame! :)

Here's one more from me...

Indian Army HAL Rudra attack helicopter

IMO, the black colour looks awesome on this attack chopper. Wonder if the army will keep it black or paint it in the camouflage livery!

Vivek Manvi,

Went through your album, and would like to compliment your composition skills. I'm a complete amateur in this field, but from my limited experience, I know it requires foresight, patience & timing to compose a good image.

I am using one with watermark and all - the watermark serves as a reminder of why my desktop takes my breath away every morning when I boot up.

That isn't really effective in stopping people from downloading the image. But the media abounds with photo-chors, so original photographers like pyogi have to at least try to stop them.

@shiv saar, Thank you :-)
@nachiket thank you for speaking my words

Hey guys what do you think of my watermark, i designed it with suggestions from fellow photographers some even from this forum.
One of the principles of the watermark is that it should be like a "bikini" :wink: which it is :-) and to give some one interested in higher resolution image to be able to contact me.
The placement is unobtrusive so please enjoy the image, leave a nice comment for me to cherish, I am thrilled by each of the views/reviews i get on my images :-)
I have a good number of images very high resolution, which can be printed into posters / hoardings!

The right click protection is no fool proof way of protecting images online am sure you geeks would agree. That said, I really cannot stop a determined image thief,
But yes, if it gets used for commercial value i *will* send a bill with a copyright notice.

Just for those who did not know, I am a full time photographer and i have hungry mouths to feed, the equipment that i use does not come cheap, even if its rented!

Cheers!

Oh ,please no watermarks in the middle ! BR has so many great photos in archives, but not a single one is usable in any way due to big ugly 3-D watermarks.
I dislike bloggers like Aroor for similar reason. He'll put his watermark on images which aren't his. He is not even paying a single rupee for hosting the images either, but a majority of slides from seminars, pictures from websites, press releases etc are marked with his watermark.
If the quality of pictures is as good as those clicked by Photoyogi, Kedar, Manvi, Abhishek and some others, I'm sure that a lot of people (including yours truly) will be more than happy to pay for such images, posters, and other stuff with or without watermarks. If it's just for hobby, content creator is usually happy with an acknowledgement of source, a backlink etc. But please, don't spoil such stunning images with intrusive watermarks.

An impressive display from the HAL guys with this variant of the ALH

@jamwal --> I will retain the watermarks to be unobtrusive so that most of you can get to view these lovely birds the way its to be viewed.
It will get copied, I guess its their form of flattery :-?
If you folks do see my images being used do let me know so i can follow up with them.
PS i have my watermarks in place on the aircraft so it can be identified even when printed.

Very nice pics Pyogi. You should probably put a stylish type of watermark right in the middle. Too many photochors like Prasun Chorgupta.

PS: Which camera and lens are you using?

Thanks. The current watermarking scheme is just fine. If you plan on selling these in any format, please let us know.

Tell me about it. Sengupta actually used a picture from my site for one of his 'breaking news'.
My point is that unless taken by professional photographers, these pictures are meant to be distributed for fans and jingos. You start putting big ugly watermarks for whatever reason and just spoil the experience. Just compare the number and quality of photographs related to Indian military to that of other countries. As one member wrote in this thread itself that some Indians in audience didn't even realise that the Tejas was Indian. People know more about F-16, Apache, Gripen than Indian weapon systems. You can't help change this mindset by taking some amazing pictures and then intentionally spoiling them.

People willing to pay just can't find the right sources every time. Not everyone has the time or resources. If it's hard to buy legally, people will just steal it.
