When shall we be seeing a high resolution X-band SAR like the one on RISAT-2?

X band Sar will come after RISAT 3, probably around 2016-17.

bhai sab kushal mangal hai??

 

[BlueDot_in_Space]

@BlueDot_in_Space A few questions-

1) When will ISRO's L-band radar be operational?

2) When will the follow on launch to the ATV-D01 occur, its been nearly three years now since that test?

3) Is that, the pic that S-DUCT picked out, really a KKV?

1) 3 years.

2) Not sure. Last I know, engine and other components were under manufacturing.

3) Nop. Thats phased array X-band antenna for communication on RISAT1.

Is it a KKV.?

Phased Array X band antenna for satellite communication using beam forming. Remote sensing sats are highly agile, so PAA antenna is used to keep the data bean focused on the receiver station on earth, while the satellite is maneuvered.

ISRO's Semi-cryogenic Engine specifications :

Thrust (vacuum) - 2000 kN
Isp (vacuum) - 3285 N-s/kg
Chamber Pressure - 18 MPa
Mixture Ratio - 2.65
Thrust Throttling - 65-105 (% of nominal thrust)
Engine gimbal - 8 degrees (in two planes)

More info:Will have staged combustion power cycle with single preburner.

they must get cryogenic working in gslv next year

 

[S-DUCT]

they must get cryogenic working in gslv next year

Next year or in this december.?

@BlueDot_in_Space

Is there a C 50 cryo stage underdevelopment?Do ISRO has any plans to replace the L 110 stage on LVM3 with a semicryo one?What will be the LEO and GTO capability in that case?

Next year or in this december.?

just giving them one more month...........

In mission mode | Frontline

You asked about the Unified Launch Vehicle. It is a future expendable launch vehicle concept. It is modular in shape, comprising semi-cryogenics as booster, a cryogenics as upper stage and strap-ons of different magnitudes made of solid rockets. It can be S-200, S-139 or S-9, depending on the payload requirement. The ULV is slightly futuristic.

ULV Upper stage might consist of CE-7.5,CE-20,CE-60 cryoengines.The choice of CE wil depend upon the type and payload.

The only cryo stage presently under development is C25. Regarding LVM3, Yes ISRO plans to replace the L110 with SC160 semi-cryo stage. GTO will be 6tons and LEO willl be close to 15 tons.

We need following for heavy lift capability.

1) Composite motors like Agni Series Missile.(Second and third stage If not possible in First stage)
2) Advance fuel (Like used in Bulava Missile of Russia) in first stage motor. Can it be NEPE?
3) Kerosene cryogenic boosters in first stage.

My 2 cent.
