ISRO on Saturday successfully demonstrated a new technology using an inflatable aerodynamic reducer (IAD). It states that it is a game changer with multiple applications for future missions. Designed and developed by the Vikram Sarabhai Space Center (VSSC), his IAD successfully completed a test flight on a ‘Rohini’ acoustic rocket from the Thumba Equatorial Rocket Launching Station (TERLS).

The IAD was initially folded and stored inside the rocket’s payload bay. At an altitude of about 84 km, the IAD inflated and descended into the atmosphere with the payload portion of the sounding rocket.of

A system for expansion was developed by the Liquid Propulsion Systems Center (LPSC).

The IAD systematically slowed the payload through aerodynamic drag to follow the predicted trajectory.

“This is the first time an IAD has been specifically designed for spent phase recovery. All mission objectives have been successfully demonstrated,” the Bengaluru-based space agency said in a statement. increase.

“IADs have great potential for a variety of space applications, including recovering spent rocket stages, landing payloads on Mars or Venus, and creating space habitats for manned spaceflight missions.

The Rohini Sounding Rocket is routinely used for flight demonstrations of new technologies being developed by scientists in India and abroad as well as ISRO.

Today’s flight successfully flight-tested new elements along with the IAD, including a micro video imaging system that captured the IAD’s bloom and flight, a small software defined radio telemetry transmitter, a MEMS-based acoustic sensor, and a number of new methodologies. did. ISRO said.

“These will be deployed on major missions later. Sounding rockets provide an exciting platform for experiments in the upper atmosphere,” it said.

“This demonstration opens the door to cost-effective spent stage recovery using inflatable aerodynamic reducer technology, which can also be used on ISRO’s future missions to Venus and Mars,” said Dr. ISRO President S Somanath, who witnessed the launch, said:
