Revision summary
Indian tradition speaks of vimanas in epics and in later Sanskrit technical lore. Vaimanika Shastra does not meet modern aeronautical-design tests, as an IISc review argued. Modern aeronautics is aerodynamics, propulsion, materials, and certification. DST funds that science through STIP, ANRF/SERB, TDB, INSPIRE, and supercomputing. NIF under DST is the honest bridge for testing traditional technological claims.
Model answer
Introduction
Indian Knowledge Tradition remembers flight as vimana in epic and later Sanskrit technical lore. Modern aeronautics is a physics-and-certification industry of lift, thrust, materials, and avionics. Comparison is useful as civilisational curiosity and as a warning against treating a text as a flight manual. Research policy for real aircraft and aerospace sits in DST windows that fund science, not mythology.
Body
Tradition-based aeronautics
- Epics describe Pushpaka and other vimanas as narrative craft. That is cultural memory of mobility and kingship, not a wind-tunnel report.
- Vaimanika Shastra, a modern Sanskrit compilation associated with Subbaraya Shastry and attributed to Bharadvaja, lists shapes, metals, and pilots. A 1974 Indian Institute of Science review found it unscientific as aeronautical design.
- Related IKT strengths that do feed engineering are geometry (Sulba), metallurgy, and observational astronomy — not powered flight as a documented ancient industry.
Modern aeronautics
- Modern flight rests on aerodynamics, propulsion (propeller, jet, turbofan), composites, fly-by-wire, and ICAO/DGCA certification.
- India’s modern line is HAL, CSIR-NAL, DRDO aircraft programmes, and civil aviation manufacturing — test, iterate, certify. Tradition texts do not replace that loop.
DST policies for research in this field
- Science, Technology and Innovation Policy frames public R&D; ANRF (succeeding SERB) funds investigator projects including fluids, materials, and sensors that aircraft need.
- Technology Development Board and DST’s Technology Development Programme back prototype-to-industry steps.
- INSPIRE and FIST grow the people and labs; National Supercomputing Mission (DST with MeitY) supplies the compute for CFD.
- National Innovation Foundation, autonomous under DST, documents grassroots and traditional technological ideas so that a genuine folk design can be tested, not worshipped unread.
- National Geospatial Policy (DST) and cyber-physical mission funds support navigation, drones, and materials — the live aeronautics-adjacent DST map.
The comparison should therefore honour IKT as literature and related science, and fund modern aeronautics through DST’s ordinary research rails.

Conclusion
IKT aeronautics is epic and later textual imagination, with a Vaimanika Shastra that did not survive scientific design review. Modern aeronautics is tested lift, engines, and certification. DST’s STIP, ANRF/SERB, TDB, INSPIRE, supercomputing, and NIF are the research policies that actually serve the field.

-
Did ancient India operate jet aircraft?
There is no scientific-historical evidence of certified powered flight. Epic vimanas are not engineering proof.
-
Does DST run HAL?
No. HAL and NAL sit under other departments. DST funds enabling science, prototypes, compute, and innovation scouting.

Highlight the key components of upstream and downstream activities in food processing supply chain management with suitable examples.
Food processing
Food-processing supply chains split into upstream gathering and downstream value-addition. Upstream covers farm output, FPO and mandi aggregation, and primary processing such as milling and chilling. PMKSY SAMPADA supports parks, cold chains, and clusters that join the two halves. Downstream covers secondary processing, FSSAI packing, branding, and organised retail or export. A chain fails if the cold link or the price signal back to the farmer is missing.

Give a brief account of measures adopted by the Government to provide adequate credit to the farmers.
Budget and financial system
KCC is the main short-term farm and allied credit instrument. Interest subvention and priority-sector rules cheapen and expand bank lending. NABARD refinances cooperatives and RRBs and funds rural infrastructure around the loan. PM-KISAN supports cash flow; PMFBY and warehouse receipts cut default risk. SHG and JLG routes try to reach those without land title.

Was the 'Bhoodan Movement' a part of land reforms in India? Discuss its major effects.
Land reforms
Bhoodan began with Vinoba Bhave in 1951 as a voluntary land-gift campaign. It belongs to the land-reform story in aim, not as a replacement for zamindari, tenancy, and ceiling statutes. Pledged acres exceeded securely mutated titles, so the legal harvest was thin. Gramdan tried community vesting of village land. The lasting effect is moral history plus some plots, not a finished redistribution.
