ISRO General News and Updates

[Krusty]

Honestly this just reminds how far we have to go. Developed nations had rockets more capable than GSLV back in 60s

We need to invest heavily into r n D.
And private sector must be brought in for usual launch operations so that isro can focus on argumenting capacity.

We need a 20-25 yeara strategic vision to atleast catch up if not surpass these. Nations.

PS : didn't wanted to be negative.

You aren't negative. You are just realistic. Yes, as far as LV's are concerned the heavyweights (US and USSR/Russia) had GSLV equivalent in the 60's. But imagine the headstart they had. And the fact that Nazi Germany Scientists, blueprints and knowhow were looted by these two countries after WW2 which formed the basis of their space programs which were massively funded during the Cold War. We didn't have any. So yeah, we have a Long way to go before we catch them. We are doing a good job, we have made our own cryogenic engine. It's by no means easy and only a handful of countries have mastered it. And we have bigger LVs coming out this decade. But we still have quite some distance to go...

Not sure if this has been posted already, but found a couple of interesting pictures for those who are intersted in rockets and where the current PSLV and GSLV stand in comparison to other launch vehicles and rockets of various countries

P.S: Rohini is on the list too :biggrin2:

Edit: for those who are interested, one of the Two largest rockets here (soviet) N1 was a complete and utter failure. 4 launches 4 failures and the program was scrapped. Whereas its US competitor Saturn 5 took man to the moon.

Interesting part is a look at Long March 2E.........

ULV program possibly cancelled, government will go ahead with GSLV Mk3.
@Chinmoy @ezsasa @shiphone @Akask kumar
This is from the abstract of a talk on 'Future of Space Transportation' by Shri. S. Somanath, Director, Liquid Propulsion Systems Center at National Space Science Symposium.

''The semi-cryogenic stage with 200 ton propellant loading will replace the present earth storable core stage of LVM3 to enhance the payload capability to 6 tons. A heavy lift launch vehicle having 8 to 10 ton GTO payload capability based on bigger solid boosters, a semi-cryogenic core stage and clustered cryogenic upper stage is configured and is under detailed study. A clustered semi-cryo booster stage with 4 to 5 engines and with 500 ton propellant loading can be the booster stage of future heavy lift vehicle or a two stage human rated vehicle. Such a semicryo booster stage can be recovered and reused as well taking advantage of the throttling capability of the engine.''
LVM 3 upgrade road map towards HLV.

HLV (?)

And they are contemplating partially reusable VTVL launchers with 5 engine clustered configuration for first stage. That stage looks good enough for a moon rocket !!!

Payload to GTO is some 14 tonne.

this is how i got it..
current GSLV load capacity- 4 tonne
with semicryo core stage it will be boosted to 6 tonne..
later clustered cryo stage will be used with bigger solid booster to give it 8-10 capability
then in future clustered semi-cryo stage core stage will be incorporated giving it recovery capability and more push..

so its evident now that the futuristic HLV will be a partially recovery rocket(minus the solid boosters)

its good that ULV is dropped ,which means more focus and fund will be directed to HLV. ISRO is being realistic..carrying two rocket development program side by side must be difficult and we are short on fund..

but there is a change according to earlier info future GSLV/HLV was having two cryo stage but this one is having one(clustered)

first thing first .. get the GSLV MK3 in air.. we have waited enough..

ULV was supposed to be a replacement of PSLV GSLV Mk2 and Mk3 by a common core and different solid boosters .

Both ULV and HLV are required for future missions .

So where does this 'ULV is cancelled' comes from ??

ULV is a medium to mid heavy capacity launch system family (this time with modular approach) but we have that already.

Story of the Week - Indian Space Research Organization
High Altitude Flight Acceptance test of CE20 Engine conducted successfully

GSLV MKIII, future launch vehicle of ISRO, capable of launching 4-ton class spacecraft in Geo Transfer Orbit (GTO) is in the advanced stage of realisation. It consists of two solid strap-ons (S200) motors, one earth storable liquid core stage (L110) and the indigenously developed C25 cryogenic stage. The C25 stage is powered by CE20 cryogenic engine. The first CE20 flight engine acceptance test was successfully conducted for duration of 25s in high altitude simulation test facility during December 2016. This flight acceptance is an important milestone for ISRO as it could successfully cross the major engine development endeavors in the maiden attempt. This engine was conceived, configured, designed, fabricated and developed by Liquid Propulsion Systems Centre (LPSC).

LPSC is the centre for design, development and realisation of liquid propulsion stages for ISRO's Launch Vehicles. Development of fluid control valves, transducers, propellant management devices for vacuum conditions and other key components of liquid propulsion systems are also under the purview of LPSC.

To test the Engine at flight identical conditions, High Altitude Test (HAT) facility was established at IPRC, Mahendragiri. This facility allows testing of the CE20 engine at its full area ratio in vacuum condition which otherwise would experience flow separation at sea level ambient pressures.

The successful engine testing in high altitude condition was preceded by multiple tests on two engines with sea level nozzle divergent (area ratio 10). The development test conducted on these engines provided confidence in the design. The design of the flight nozzle was also validated in the medium duration High Altitude Test programme.

The Engine High Altitude Test Programme contained a series of high altitude tests (5 hot tests with a cumulative duration of 41.20s) to demonstrate the vacuum ignition, validate the nozzle performance, propellant flow build up characteristics, chill down performance and demonstrate the ignition margins. All the test objectives were successfully achieved in this test programme. The testing of engine in HAT facility has also helped in finalising the engine start and shut down sequence for flight. Summing up, the test programme has imparted good confidence on the performance and functioning of CE20 Engine in GSLV MKIII (LVM3)-D1 mission.

The realisation of flight stage for the GSLV MKIII (LVM3)-D1 mission is in progress and the first mission is expected by early 2017.

Baap re baap!!

@Krusty Before you got this pic, kisi paki ne haath saaf kar liye iss par!

 

[indiatester]

I will change it to "Perfaarmance aassaam" after debut of big boy to ISRO in March.:biggrin2:

Hey... thats my favourite part. :-(

 

[Akask kumar]

ULV was supposed to be a replacement of PSLV GSLV Mk2 and Mk3 by a common core and different solid boosters .

Both ULV and HLV are required for future missions .

So where does this 'ULV is cancelled' comes from ??

ULV was for sats /sceintific payload launches.whereas HLV is for human space flight n heavy payload launches,may be sapce station too. by dropping ulv ISRO made human space flight,scientific mission to other heavenly bodies a reality..

 

[Akask kumar]

You aren't negative. You are just realistic. Yes, as far as LV's are concerned the heavyweights (US and USSR/Russia) had GSLV equivalent in the 60's. But imagine the headstart they had. And the fact that Nazi Germany Scientists, blueprints and knowhow were looted by these two countries after WW2 which formed the basis of their space programs which were massively funded during the Cold War. We didn't have any. So yeah, we have a Long way to go before we catch them. We are doing a good job, we have made our own cryogenic engine. It's by no means easy and only a handful of countries have mastered it. And we have bigger LVs coming out this decade. But we still have quite some distance to go...

not long path.. all we have to do is develop the HLV.. this rocket will help us to stand near the US , russia in terms of launch capability.. as per news by 2020 HLV will be a reality..

Launch capability, yes, but manned crafts, re-entry and space stations are entirely different beasts..

 

[kurup]

ULV is a medium to mid heavy capacity launch system family (this time with modular approach) but we have that already.

We already have that capability but with 3 entirely different LVs .... ULVs modular approach OTOH will help reduce the cost of launch even lower by using the same core .

ISRO can carry on with ULV and HLV as parallel programs .

 

[Indx TechStyle]

But as per the statement of Dr. Somnath (indirectly), ISRO is emphasizing the capability first, quality later.

yes they can but the speed would be low as funds and effort will get distributed.. dnt forget development of RLV is also going on..

Naeem Akhtar flags off students’ exposure visit to ISRO

Jammu and Kashmir Minister for Education, Naeem Akhtar, and Minister of State for Education, Ms Priya Sethi, today flagged off an exposure visit of 44 students for Space Application Centre (SAC) at Indian Space Research Organization (ISRO) under Rashtriya Avishkar Abhiyaan component of Rashtriya Madhyamik Siksha Abhiyaan (RMSA).

Naeem Akhtar, while interacting with the students, appreciated their keenness for knowledge and asked them to optimally utilize this educative tour to enlighten themselves with latest happenings and achievements in the field. He said that it is the endeavor of present dispensation to organize such exposure visits for state’s students with an objective to broaden their vision for a brighter future. Visits to institutes of repute such as ISRO, IITs, IIMs will enable the students to see the places of historical importance for better understanding of the cultural heritage of the country, he added.

Priya Sethi also interacted with the students and complemented the RMSA team for according equal representation to all the three regions with taking 24 students from Kashmir division with participation from both Kargil and Leh and 20 from Jammu division.

Under the scheme, about 2500 students of the state are being sent by the RMSA to various cities of the country for visits to Institutions of excellence and places of prominence.

State Project Director, RMSA/SSA, Saugat Biswas, informed that the idea behind the scheme is to foster scientific temper, as well as expose the students to various career options available to them across the country.

This tour has been organized with support from the Inspire team of SMVDU, Katra led by Dr Sunil Wanchoo.

During the tour, the students will also visit the IIM – Ahmadabad, the National Institute of Design and Gandhi Ashram.

ya but we have the tech and some tech like rendezvou is under development. all we need a vehicle and some more fund to test the tech in extreme conditions. 2025 is the fine date for human space flight .. by that time we will have fully tested HLV and relevant tech..
