[00:00:12]Okay.

[00:00:23]Basically, I liked mechanical engineering.

[00:00:26]>> Engineering.

[00:00:27]>> Engineering. Yes, of course.

[00:00:32]Which one you prefer? Civil orchan.

[00:00:35]Okay. Actually max.

[00:00:41]Okay.

[00:00:52]Okay. So I chose mechanical and I got it also.

[00:00:54]>> Okay.

[00:00:56]other US success through that and you all the credit all >> alone great success and that project was considered to be probably number one for so many years I'm talking about 19 65 actually okay sir you decided >> I decided that I I liked aerospace mechanical engineering.

[00:01:26]>> Yes.

[00:01:32]Actually I I joined group right >> group rocket engineering division.

[00:01:40]>> Okay.

[00:01:41]>> Shortly known as red >> red. Okay.

[00:01:44]>> And is known as rocket engineer.

[00:01:46]>> Yes.

[00:01:49]Being an Indian.

[00:01:54]Yeah. Yeah.

[00:01:58]Golden person.

[00:01:59]>> Yeah. Yeah. He's a great person. Great person. Okay.

[00:02:12]What is it behind?

[00:02:19]I took a model along with me.

[00:02:23]explain. I'll take the model with me.

[00:02:25]Yeah, sure. Sure, sure.

[00:02:36]No idea what is happening inside this actually.

[00:02:46]No problem. No problem. Now this is a model of GSLV the one which we launched.

[00:02:53]Okay I think that that is exactly this model. Oh >> this is a three-stage vehicle.

[00:02:59]>> Okay and the first stage.

[00:03:08]Okay they are liquid stages. So liquid stage that is second stage. Third also is liquid stage. Okay.id.

[00:03:25]>> Oh, which is this attached?

[00:03:27]>> Yeah. No, no, that's a main booster.

[00:03:29]>> Oh, okay. Okay.

[00:03:30]>> What you are seeing inside the center.

[00:03:32]>> Okay. That is about 139 tons of solid propellant.

[00:03:39]Each strap on will be 40 tons 4060 t >> liquids is going to be 160 tons solid is 139 tons. So approximately 300 tons take off sort of thrust. Second stage is nothing but this same that is 37.5 37.5.

[00:04:11]>> The third one is a cryogenic.

[00:04:13]Now this is one of the dream vehicle which we should have launched maybe in 199 perhaps even before 20 2000 though we are late by 15 years. Now this vehicle I mean you see the whole thing is called a vehicle.

[00:04:32]>> You may confuse between an ordinary vehicle.

[00:04:35]>> Ah correct.

[00:04:39]So I want to know the detail very simple that vehicle carries people. This vehicle carries a satellite. Now the satellite is called the payload. Oh satellite shield. Oh heat shield. This is to protect the satellite.

[00:04:58]>> Oh, I satellite.

[00:05:00]>> Okay.

[00:05:01]>> So, this is actually but for the core stage.

[00:05:06]>> Oh, okay.

[00:05:07]>> So, I we and our team particularly myself we have contributed for example all the liquid stages uh these 40 tons and then 37.5 t and cryogenic I was the project director everything is today. So the whole thing is called GSLV that is called TV that isat communications phone communication satellite apart from this lot of applications are there for example you have weather predictions you know you have and then there are satellites which will be working for Watchdog as a watchdog.

[00:06:02]There is a satellite and then there are satellites for example fisherman.

[00:06:20]These are all going on. This is there.

[00:06:22]So actually we have reached a stage where we cannot live without a satellite.

[00:06:33]>> What will be your situation?

[00:06:35]>> Television television working there is no satellite. There are no television channels or you are not able to dial somebody through your cell phone.

[00:06:45]>> Oh it's impossible.

[00:06:51]You have gone abroad. You have experienced a lot of experiences.

[00:06:58]How do you travel?

[00:07:01]It's a it's a big story.

[00:07:07]When I was in London, I think that is a time I was in Rolls-Royce. Roll you know they make the rocket complete hydraulics laboratory.

[00:07:29]>> Okay. So let me place it here.

[00:07:31]>> Hydraulics laboratory laboratory in charge there is a director mutual discussion. I asked him actually he was feeling sort of guilty that the Britishers were sort of standing in our way of development because of >> before freedom.

[00:07:49]>> Yes. Before freedom in fact he was working as a captain or colonel in India during that time.

[00:07:55]>> Oh.

[00:07:56]>> So he was feeling guilty.

[00:07:58]>> Guilty. Okay.

[00:07:59]>> So he said that how see you think I I want to do something for you. So I asked him can you give the hydraulics slab? He said, "Yes."

[00:08:10]>> And that would have been at least $400 million.

[00:08:15]Oh, >> correct.

[00:08:16]>> Then Dr. Sarai agreed to spend money to transport it here >> which we did.

[00:08:24]I had an opportunity to know about the so-called engine version is called M4.

[00:08:37]>> Okay.

[00:08:40]L7ation soal Viking too. Oh >> and then that part of it is what is called engine. Okay.

[00:09:02]>> We are using it all through this vehicle today.

[00:09:08]Okay.

[00:09:10]Difference various versions are there.ID4 But the preparation time is more you should be able to once you decide you want to launch then you must act quickly but >> because of the low temperature storage.

[00:09:44]>> Okay. Okay. Then handling difficulty loading the propellent you have to keep it always readily on the launch give a command it will go.

[00:09:56]>> Oh I see.

[00:09:57]So cryogenic was never used as a missile.

[00:10:00]>> Oh I see.

[00:10:01]>> Nowhere in the world you have a cryogenic missile.

[00:10:04]>> Oh I see. Okay.
