MINISTER OF STATE IN THE PRIME MINISTER`S OFFICE
(SHRI PRITHVIRAJ CHAVAN):
(a), (b), (c) & (d) A statement is laid on the Table of the House.
STATEMENT LAID ON THE TABLE OF THE LOK SABHA IN REPLY TO
PARTS (a), (b), (c) & (d) OF STARRED QUESTION NO.221 REGARDING
`TEST ON USE OF CRYOGENIC TECHNOLOGY` BY DR. THOKCHOM
MEINYA, FOR ANSWER ON DECEMBER 06, 2006.
(a) & (b) Yes, Sir. On 28th October 2006, ISRO has successfully carried out the ground
hot test of the indigenous Cryogenic Upper Stage at the Liquid Propulsion
Systems Centre test complex, Mahendragiri. The indigenous stage used the
cryogenic engine which produced a thrust of 69.5 Kilo Newton. During the
test, a number of stage elements like engine, insulated propellant tanks,
booster pumps, fill and drain systems, pressurization systems, interstage
structures, etc as per flight standards worked in unison. The test was for a
duration of 50 seconds and the performance was as predicted.
(c) Yes, Sir.
(d) While the recent stage level hot test has demonstrated the design adequacy
and performance of the integrated flight system, further qualification test for
this flight unit is planned for flight duration of 720 seconds. After completion
of the qualification test, the indigenous cryogenic stage is planned to be flight
tested in the Geo-Synchronous Satellite Launch Vehicle (GSLV- D3) mission
next year.
