Q. With reference to “PraVaHa” software developed by ISRO, which of the following statements is/are correct?
1. It is a path-breaking feat by Vikram Sarabhai Space Centre.
2. Initial aerodynamic design of space vehicles requires evaluation of a large number of configurations.
Select the correct answer from the codes given below:
a) Only 2
b) Neither 1 nor 2
c) Only 1
d) Both 1 and 2
Question from UPPSC Prelims 2024
Correct Answer: d) Both 1 and 2.
Explanation:
The “PraVaHa” software developed by ISRO is a significant advancement in computational fluid dynamics (CFD) specifically designed for aerospace applications.
1. It is a path-breaking feat by Vikram Sarabhai Space Centre.
This statement is correct. The PraVaHa software was developed at the Vikram Sarabhai Space Centre (VSSC), which is part of ISRO, and is considered a major achievement in indigenous aerospace technology aimed at enhancing India’s capabilities in human spaceflight missions.
2. Initial aerodynamic design of space vehicles requires evaluation of a large number of configurations.
This statement is also correct. The initial aerodynamic design indeed necessitates the evaluation of numerous configurations to determine optimal designs that can withstand the severe aerodynamic and aerothermal loads experienced during launch and re-entry.
Given that both statements are correct, the answer is:d) Both 1 and 2.
