Speaking to Dt Next, Dr K.Sivan, director of ISRO’s VikramSarabhai Space Centre, said earlier ISRO imported a few components from abroad,but now it has embarked on a mission to produce parts in India. “If the weightof the upper stage in the launch vehicle (rocket) is higher, then the mass ofthe payload would decrease as rockets cannot carry payloads of higher mass.
As we have to bring down weight in the upper stage of therocket, we (ISRO-VSSC) are developing materials which will have high strengthto weight ratio, as the weight has to be less and withstand load too,” he said.Pointing out that VSSC has developed a sponge type base material for Titaniumused in the rocket, the VSSC director said that it has transferred thetechnology to industries so that they could produce it for ISRO so thatindustries too get developed.
“We have replaced Aluminium with Titanium, whichbrought down the cost of the vehicle significantly. We have now replaced aspecific type of steel in the launch vehicle, which too has saved the cost ofvehicle by Rs.10 to 20 crore. We have also changed the manufacturing processand the farm welding technology, which we use now has facilitated us to cutdown cost by Rs. 20 crores, he ended.
