The Council for Scientific and Industrial Research – National Space Laboratories (CSIR-NAL) said the main launch vehicle – the Mark III, or LVM3 – which carried Chandrayaan-3 On Friday, more than 3,000 units were tested in a wind tunnel at the Bengaluru facility.
A wind tunnel tests the aerodynamics of missiles and aircraft. It helps manufacturers understand the nature of the airflow over and around the missile and other aircraft.
An official from NAL said that more than 3,000 wind tunnel tests were performed to characterize the LVM3 vehicle and that these included force measurements, static and unstable pressure measurements, and nozzle load studies apart from surface and outflow visualization studies.
“Based on these wind tunnel tests, the configuration underwent significant design changes in 2014-2015. All LVM3 stages with Chandrayaan-3 payload fairings were acoustically tagged at this facility and allowed to launch, which was mission critical,” the official added. .
A statement from CSIR-NAL said that CSIR National Space Laboratories’ 1.2-meter triangular wind tunnel has served as the backbone of all national space programs since 1967.
A statement from CSIR-NAL said that CSIR-National Aerospace Laboratories’ 1.2-meter triangular wind tunnel has served as the backbone of all national aerospace programs since 1967. “All major high-speed aviation vehicles developed by the Defense Research Development Organization, ASRO graduated India, Hindustan Aeronautics Limited and the Aeronautical Development Agency from this facility.The highest speed of this tunnel is Mach 4.0, four times the speed of sound.The mission of this facility is to provide advanced technical solutions for national aerospace programs, such as combat aircraft, defense systems, launch vehicles and space systems.The The contribution of this facility to LCA-Tejas, PSLV, GSLV, RLV fighter aircraft and missiles like Agni, Prithvi, AKASH, Brahmos, etc. is remarkable.”
The triangular wind tunnel is capable of testing in three speed regimes – subsonic, transsonic, and supersonic.
The main launch vehicle, LVM3, which carried the Chandrayaan-3 module was extensively tested and featured at this facility. LVM3 testing began in 2001. The LVM3 (GSLV MK3) is designed for geosynchronous orbital missions and has a payload width of 5 meters to be capable of To accommodate large payload units such as space station parts. .
