ya it is around merlin engine

Merlin has Sea level ISP of 285sec...our SCE-200 will have 300sec....Sea Level ISP

@Moonlander ISRO will use ADMIRE test vehicle to prove Supersonic retro propulsion & vertical landing, SpaceX used Grasshopper to do the same.
1.How you guys are gonna prove VTVL tech, Are you also planning for a similar kind of tech demonstrater?
2. Isn't it good way to develop a Falcon1 like small LV with a single engine in 1st stage to prove the basic techs instead of directly going for medium LV with 9 engine?

1. We will surely do a hop test.
2. See when designing rockets the major R&D part contributes to man power before component testing and designing. a small rocket is completely different than designing a big one, if you remember spacex wrapped work on Falcon 1 after 4 launches yet it took them 6 more years to come up with falcon 9. If I go with this approach then i am increasing my time and money involved by significant margin while gaining very less on the technology aspect.

Ya'll Nibbiars then why not modularity like the ISRO straps boosters?.

Yes , small LV is completely different than large LV, it will have different aerodynamics, control Laws etc....I agree with this ...but my point is.....small LV is cheaper than a bigger LV....in small LV u can afford failures when compared to the bigger one....also, the experience, Know-how & know-why we gain during the small LV development will reduce uncertainties during the development of larger LV, which also may reduce the chances of failure for the bigger one.

I don't fully agree on that, everything will change surely launching a SLV first will bring confidence and failure in that will cost less money but there is no guarantee that you will succeed in developing a HLV after developing a SLV, like what happens with GSLV or what happened with FALCON 9 in the beginning.

More the number of boosters involved more complex will be the reusability.

 

[Haldilal]

Ya'll Nibbiars The H3 would be again on the launch pad this time ready to launch in few months.

 

[SKC]

Ya'll Nibbiars @Moonlander Nibba what you thoughts on the PNG/CNG powered LV?.

Their Energia system was best if had managed to survive till now.
Each booster could land like a plane.

nice place

I had asked a question above, that how much time does it takes to develop a liquid rocket engine.

what are your estimates ??

Will have good sleep on sofa. Are washroom equipped with shower then?. I can spend a whole weekday there.

I have worked with teams who took less than 3 months to design, manufacture and build a 18kN engine and i have worked with teams who took over 2 years for 25kN engines. So at the end everything is about how would you like to approach your engine development. Are you willing to flood in some extra money and do rapid prototyping and shorten the team frame required or do you want to follow an economical methodology of hit and trial, followed by computation simulations and analytical approach which for sure slow things down or you can come up with a hybrid, you get what I am saying right ?

Scale of economics.

Scale of economics.

Kind off and risk taking abilities, things can blow out of proportion very fast in rapid prototyping.
