Bengaluru: India’s first privately-held Polar Satellite Launch Vehicle (PSLV), built by a consortium of HAL and L&T, will be powered by a technology demonstration satellite (TDS-1) that tests up to 35 new indigenous technologies.
ISRO Chairman v Narayanan revealed this in an exclusive interview with TOI, with the launch scheduled for the third quarter of this year as the first PSLV manufactured by the private sector under five rocket contracts He said he would mark the
The vehicle is in a “high-level stage of realization” and ISRO provides technical guidance to its industrial partners.
“It’s called the Technology Demonstration Satellite (TDS-1)… There are 35 experimental ones, particularly those that use electric propulsion along with chemical propulsion. Also, indigenous atomic clocks , demonstrates quantum payloads. So there’s a lot of stuff in the store. And now the payload is being realized.”
The final number of experiments targeted at 35 will be confirmed later. In the TDS-1, ISRO will test the electric propulsion thruster of a 300 Milli-Newton (300mn) developed at ISRO’s Liquid Propulsion System Center (LPSC). The new thruster is currently undergoing lifecycle testing.
He said that Isro has previously tried 75mn thrusters on the GSAT-9, but what will happen with the TDS-1 “is the first time a completely indigenous system has been deployed.” The organization previously developed related components internally, such as power supply processing equipment, control systems, and propellant tanks.
NGLV progresses
In a wide range of interviews, Narayanan also detailed information about ISRO’s Next Generation Launch Vehicle (NGLV) program. “… Our first launcher, SLV-3, had the ability to throw about 35-40 kg into low Earth orbit (LEO). Then, our heaviest rocket (LVM-3) ) can consume about 8,500 kg in Leo. Currently, at NGLV, the lift in mass is about 1,000 tons, the vehicle height is 93m, and the height of a 30-35-storey building is I will,” Narayanan said.
“The NGLV features three propulsion stages and two strap-on boosters. The core stage is powered by nine rocksmethane engines, each producing 110 tons of thrust, with a propellant load of 475 tons. In the two stages, 128 tons of propellant is used using two Loxmethane engines of the same class. In the upper stage, the Lox Hydrogen Cryogenic Engine (C-32) with a propellant capacity of 32 tons I use it,” Narayanan said.
He said the compositional studies have been completed and the ISRO is in the process of developing subsystems such as engines. “The design of the 11 Loxmethane engines (9 core stages and 2 in stage 2) has been finalized and we are in the process of providing clearance for production,” he said.
Although the mission research has been completed, he says rocket structures and tank designs are ongoing, adding that Isro is currently in discussion with industry partners for manufacturing, and is developing the necessary test facilities at the same time. Ta.
