With reference to the Vikas engine of ISRO, consider the following st...
Option a is correct.
Statement 1 is correct. Vikas belongs to family of liquid fuelled rocket engines conceptualized and designed by ISRO’s Liquid Propulsion Systems Centre in the 1970s.
Statement 2 is correct. It is the workhorse liquid rocket engine powering second stage of India’s Polar Satellite Launch Vehicle (PSLV), second stage and four strap-on stages of Geosynchronous Launch Vehicle (GSLV) and is part of first stage i.e., twin engine core liquid stage (L110) of GSLV Mk-III.
Statement 3 is incorrect. The early production VIKAS engines used imported French components which were later replaced by domestically produced equivalents. ISRO and the French Space agency signed a deal to co-develop a 60-ton liquid-fuel engine. While the engine was not an all-new model, it was an improvised version of a smaller French engine in the Viking series. The French had named their engine Viking, but the Indian-side, led by Nambi Narayanan, that negotiated the contract had decided on an Indian name - Vikas.
Knowledge Base: Liquid-fueled engines are more fuel-efficient as they can be switched on and off, they can lift heavier payloads/satellites. Liquid engines also have lesser vibration and can burn for longer durations when compared to their solid counterparts. While a solid engine burns out after use, the liquid engine can be tested, re-used after cleaning and reassembly. Most advanced rockets in the world are primarily dependent
on liquid-fueled engines. If and when solids are used, they are only for the initial thrust (using boosters) at lift-off.
A cryogenic rocket engine is a rocket engine that uses a cryogenic fuel or oxidizer, that is, its fuel or oxidizer (or both) are gases liquefied and stored at very low temperature.

With reference to the Vikas engine of ISRO, consider the following st...
The correct answer is option 'A', i.e., statements 1 and 2 only.
Let's analyze each statement:
Statement 1:
The statement is correct. The Vikas engine belongs to the family of liquid-fueled rocket engines. It uses liquid propellants, specifically Unsymmetrical Dimethylhydrazine (UDMH) as fuel and Nitrogen Tetroxide (N2O4) as oxidizer. Liquid-fueled rocket engines have the advantage of being able to be throttled or shut down completely, providing better control over the rocket's trajectory.
Statement 2:
The statement is correct. The Vikas engine is used to power both the Polar Satellite Launch Vehicle (PSLV) and the Geosynchronous Satellite Launch Vehicle (GSLV). The PSLV is primarily used for launching satellites into polar orbits, while the GSLV is used for launching satellites into geostationary orbits. The Vikas engine is a crucial component of these launch vehicles, providing the necessary thrust for the initial stages of the launch.
Statement 3:
The statement is incorrect. The Vikas engine has not been indigenously designed and made with no foreign contribution. In fact, the Vikas engine is based on the French Viking engine, which was developed by the French space agency CNES. The Indian Space Research Organization (ISRO) obtained the technology for the Viking engine and modified it to suit their requirements, resulting in the Vikas engine. Therefore, there has been a foreign contribution in the design and development of the Vikas engine.
In conclusion, statements 1 and 2 are correct, while statement 3 is incorrect. The Vikas engine belongs to the family of liquid-fueled rocket engines and is used to power both the PSLV and GSLV. However, it has been developed based on the French Viking engine, indicating foreign contribution in its design and development.
