Updates from ISRO's annual report 2010.

Update on GSLV MK3

Significant progress has been made in the development of Geosynchronous Satellite Launch Vehicle GSLV Mark III which is currently under advanced stage of development for launching 4 ton class of communication satellites.
• The first static test of ISRO’s largest solid booster S-200 was conducted successfully on January 24, 2010 at SDSC SHAR, Sriharikota. S-200 is the third largest solid booster in the world, next to the RSRM solid booster of Space Shuttle and P230 solid booster of ARIANE-5. The S-200 solid booster will form the strap-on stage for the Geosynchronous Satellite Launch Vehicle Mark III (GSLV Mk III). Preparations for the static testing of one more S-200 solid booster is in advanced stage

• The second static testing of the liquid core stage (L-110) of GSLV Mk III was conducted successfully for its full flight duration of 200 seconds at Liquid Propulsion Systems Centre (LPSC) test facility at Mahendragiri on September 8, 2010.

• Development of subsystems of Cryogenic Engine for the upper stage for GSLV Mark III is progressing The development of cryogenic engine for GSLV Mk III is progressing well. The hot test of Integrated Turbo Pump (TP) with Gas Generator (GG) in bootstrap mode was conducted for 40 seconds on August 13, 2010. The bootstrap mode starting of CE20 turbo-pump system with stored gas start up system was carried out and safe ignition of gas generator demonstrated.

Subsystem level development tests have been completed in most of the areas. The project has entered into the phase of stage level tests for propulsion modules and vehicle level tests like Ground Resonance Test (GRT). Based on the development status of various subsystems GSLV MkIII vehicle, the Project has worked out the plan for achieving the first experimental launch during 2012.

Advanced Technology Vehicles and Sounding Rockets Project (ATVP)

The flight test of the new generation high performance sounding rocket developed by VSSC was successfully conducted on March 3, 2010 from the Satish Dhawan Space Centre (SDSC), SHAR. The Advanced Technology Vehicle (ATV D-01), weighing 3 tonnes at lift-off is the heaviest sounding rocket ever developed by ISRO. The successful flight testing of ATV D-01 is a step ahead towards the advanced technology initiative taken up in the area of Air-Breathing Propulsion.
The first flight of ATV D-01 was designated towards vehicle characterisation and used aerodynamic and mass simulated passive scramjet engine modules mounted at the aft end of the sustainer. The Nose Cone houses Telemetry, Tracking, Command, Real Time Decision (RTD), sequencing and instrumentation payloads. Real Time Decision (RTD) based second stage ignition was successfully implemented in flight and the required dwell time within “Mach number-dynamic pressure” (M-q) window was achieved.

ATV offers a cost effective test bed for demonstrating Air-Breathing Propulsion (ABP). Since the development of SLV, ASLV, PSLV and GSLV launch vehicles, ATV is a major rocket development activity taken up by VSSC towards the demonstration of Air-Breathing Engine Technology. ATV D-01 will be followed by flights of active scramjet engine testing and ramjet engine testing, finally leading to the full configuration of Dual Mode Ramjet (DMRJ) module testing in the Mach range 3 to 10.

Air-Breathing Technology and Scramjet Engines
Air-Breathing Propulsion along with Reusable Launch Vehicle technology is a viable option for meeting the ISRO’s futuristic challenge – low cost access to Space. Air-Breathing Propulsion, as the name indicates, uses atmospheric Oxygen for combustion of the on-board fuel in contrast with conventional rockets which carry both Oxygen and fuel onboard, leading to improvement in vehicle operability and significant reduction in size and overall costs.
VSSC has taken up a systematic R&D programme demonstrating stable supersonic combustion through a series of ground tests on the Air-Breathing Propulsion Technology and the flight demonstration is planned with the Advanced Technology Vehicle (ATV). Flight configuration combustor tests at high temperatures of 1950 K were carried out and stable supersonic combustion was established. A full mechanical / structural design cycle of the scramjet engine has been carried out. CFD computations were carried out for the generation of detailed flow parameters for heat transfer and load estimation. During the year, an engineering model of the active scramjet engine module has been realised. This includes all critical subsystems of the engine module.

Reusable Launch Vehicle–Technology Demonstrator (RLV-TD)
As a first step towards realising a Two Stage to Orbit (TSTO) fully re-usable launch vehicle, a series of technology demonstration missions have been conceived. For this purpose a winged Reusable Launch Vehicle Technology Demonstrator (RLV-TD) has been configured.
The RLV-TD will act as a flying test bed to evaluate various technologies, viz., hypersonic flight, autonomous landing, powered cruise flight and hypersonic flight using Air breathing propulsion. First in the series of demonstration trials is the hypersonic flight experiment (HEX). During the year, all design options were finalised with titanium elevon, composite movable fin and metallic wing leading edge. Mission design has been completed with revised vehicle mass. All design related issues have been addressed and presented to the National Review Committee and clearance obtained to go ahead.:victory:soon:agree:

Space capsule(SRE2)
SRE-2 is planned to be launched using PSLV-C19 during 2011.The main objectives of SRE-2 are:

1. To confirm, improve and refine the technology elements for re-entry of an orbiting module(read Indian OV).
2. Design, development and flight demonstration of Carbon-carbon Thermal protection system.
3. Provide more opportunities for Microgravity experiments
4. To validate in flight, the hypersonic aero thermo dynamic models and data.

The payloads/experiments considered for SRE-2 are as follows:
• Isothermal Heating Furnace Mk II: For measuring the gravitational effects during liquid phase sintering of powder metallurgy products/ study on tapping phenomenal potential of Carbon nano tubes for composites. This experiment is a collaborative effort between IIT, Kanpur and VSSC.

• CCMB Bioreactor: To study the Biological effects of microgravity on E-coli bacteria. The Bioreactor is developed by CCMB, Hyderabad.

• Japan India Microbial Cultivation Unit: To study the effect of microgravity on the growth of Cynobacteria. This is in collaboration between Japan and India.

• Biopan-Seed experiment: To study the effect of Microgravity and high-energy radiation on Gene Expression in relation to growth, yield and quality of medicinal plants, vegetables and rice seeds using a Biopan. This experiment is a collaborative effort of Kerala Agriculture University and Pune University.

• Space Radiation Dosimeter: To measure the energy deposited in the detector by high energy radiation and estimate the energy of the incident particle. This is developed jointly by PRL and BARC.

• Langmuir Probe: To generate a detailed electron density profile in the altitude range from 80 km to 40 km during the descent of SRE-2.

SRE capsule has four major hardware, namely Aero Thermostructure (ATS), Spacecraft platform, deceleration and floatation system and payloads. New technology developments for SRE–2 include Carbon-Carbon (C-C) Nose Cap, indigenous UHF Beacons, etc. The C-C proto hardware has been realised and qualification tests are under progress. The UHF beacon Engineering Model has been realised and link tests and pattern measurement completed. For SRE-2, thermal protection system (Silica tiles) integration on ATS and Propulsion system integration on spacecraft platform has commenced. Qualification models of Payloads have undergone functional testing. Parachutes and floats have been realised for deceleration and floatation system. Flight models of Inertial Measurement Unit (IMU) and re-entry electronics have been realised. Realisation of power electronics, Battery and S-band belt array antenna for spacecraft platform and design of Mission Management Unit (MMU) are the other highlights.

I am waiting for the RLV. hope ISRO conducts its test by end of this year.:toast_sign:

SRE2 will be the next step in getting technology maturity for INDIAN OV.
 
way for next gen engines for missiles or plane too . scrame jet will enter us in 6 th generation.
 
S-200 of GSLV mk III is the third largest solid booster in the world after RSRM solid booster of Space Shuttle and P230 solid booster of ARIANE-5.

What do you think about GSLV mk III? Its almost ready. Will be launched next year. As I said instead of mk II, they should concentrate on mk III.
 
Any one know about next flight of GSLV with our own cryogenic engine ???

I mean any official date??
 
Development of subsystems of Cryogenic Engine for the upper stage for GSLV Mark III is progressing The development of cryogenic engine for GSLV Mk III is progressing well.

I am seriously hoping this is indigenous one... This is the only news i want to hear from ISRO :pop:

Buddy, I think both are required as they suffice to different weight classes to GTO. GSLV mK3 will mostly be used for putting INSAT (heavy weight 4-5 ton) satellites. Mk2 will used for 2.5 ton class weights and will have lower launch cost.

As far I know, ISRO doesn't have facility for high altitude vacuum testing for mk2 cryo stage, but has the same for mk3 (both cryo stages are of different sizes). So I think that setbacks in mk2 doesn't affect mk3. Mk3 will also make us independent in launching all class of satellites:smokin:.

i know this but mk II problems could halt mk III launch thats what I was talking about.


So its 2012. Good to see lots of mini and micro sats are coming as well as large number of communication satellites. Chandrayaan-2 is on schedule.

The reason for the failure of the turbo pumps in mk2 was that they never tested the engine for high altitude vacuum conditions as they didnt have the facility. I read somewhere that for mk3 which has a bigger engine, they have this facility and so can check the engine for simulated vacuum conditions. So i think its just a matter of time when we operationalize the cryo stage.

But jewel of the Indian space transportation would be RLV. I am just dying to see it flying just like the boeing X37
