SATISH DHAWAN, India (ISRO PR) — In the quest to reduce the cost of access to space and to extend the frontiers of space exploration, ISRO has ventured into Reusable Launch Vehicle (RLV) and Re-entry missions, Air-breathing propulsion technology demonstration and Interplanetary missions. These missions encounter design criticalities at Hypersonic Mach number regime and need rigorous aero-thermodynamic characterisation at these Mach numbers.

In order to cater to the above need, Industrial type Hypersonic Wind Tunnel and Shock Tunnel have been established at Vikram Sarabhai Space Centre (VSSC).


ISRO Establishes Rocket Nozzle Testing Facility

ISRO_logoBANGALORE, India (ISRO PR) — Performance improvement in propulsion systems is essential towards achieving cost effective launch vehicles. Apart from propellant energetics, the nozzle plays a vital role in improving propulsion system performance. Therefore by improving performance of existing nozzles and by developing new nozzle concepts, which can operate at both low and high altitude regimes, it is possible to obtain significant gains in the delivered specific impulse of rockets. With these objectives, ISRO has established Nozzle Testing Laboratories (NTL) at Vikram Sarabhai Space CentreĀ (VSSC), Thiruvananthapuram.
