Sundara Vimana in Vaimanika Shastra: Complete Structure, Energy Systems, and Propulsion Explained

Mathomathis presents this article as a continuation of the study of the Vaimanika Shastra (Vimana Shastra) attributed to Maharshi Bharadwaaja, propounded by Venerable Subbaraya Shastry, and translated and edited by G. R. Josyer.

Following the detailed explanation of Shakuna Vimana (Article 101), we now explore the Sundara Vimana, a highly advanced Kritaka (mechanically constructed) aircraft described with intricate detail in the Shastra.

Bodhaananda Vritti – Overview of Sundara Vimana

The Sundara Vimana is described as consisting of eight primary components:

Key Structural Components

• Peetha (base platform)
• Smoke chimney (Dhooma system)
• Five gas engines
• Bhujyu metal pipe
• Wind blower (Vāta system)
• Electricity generator (Vidyud system)
• Four-faced heater (Agni system)
• Outer covering (Aavarana)

👉 Explanation:
Unlike simpler Vimanas, the Sundara Vimana integrates multiple energy systems simultaneously. It combines vāta (air), dhūma (smoke), agni (heat), and vidyut (electricity) into a unified propulsion framework. Therefore, it should be understood as a multi-energy aircraft system, not a single-engine design.

Peetha (Base Platform)

Technical Specifications

• Material: Raajaloha metal
• Shape: Square or circular
• Circumference: 100 feet
• Thickness: 8 feet
• Treatment: Heated 7 times with Manchuka oil

Structural Layout

• 24 kendras (energy centers)
• Distance between centers: 10 feet
• Each kendra size: 15 feet
• Central structure:
  • Dhooma-prasaarana naala (12 feet height)

👉 Explanation:
The Peetha is not just a base. It acts as a load-bearing platform + energy distribution grid. The 24 kendras indicate a structured layout, possibly designed for balancing mechanical and energetic forces across the Vimana.

Naalastambha (Hollow Mast)

Dimensions

• Height: 56 feet
• Diameter: 4 feet

Internal Components

• Gas vessel → 8 ft long, 4 ft high
• Water vessel → 6 ft size
• Oil tank → 4 ft (central)
• Electric crystal → 1 ft size

Fuel Ratios

• 12 parts Dhoomanjana oil
• 20 parts Shukatundika oil
• 9 parts Kulakee oil (red arsenic)

Control System

• Triple perforated wheels inside
• External rotating control wheels
• Electrical wires connected to crystal

👉 Explanation:
The Naalastambha functions as a central reactor system. It combines chemical storage, electrical conduction, and airflow control. The presence of oils, arsenic compounds, and crystals suggests an attempt to describe energy transformation mechanisms.

Dhoomodgama Yantra (Dhūma Propulsion System)

Alloy Composition

• Hima Samvardhaka → 32 parts
• Soma → 25 parts
• Sundaala → 38 parts
• Heating temperature: 712 degrees

Functional Setup

• Central pipe → 10 feet height
• Two steam pipes (north & south)
• Oil + water vessels
• Electrical input → 80 linkas
• Heat generated → 100 degrees (kakshya)

👉 Explanation:
This system produces dhūma (smoke/fumes) through heated oil and steam. When combined with pressure and electrical stimulation, it creates expulsive force, similar to the concept of jet thrust, but expressed in ancient terminology.

---

Shundaala System (Directional Control)

Structure

• Height: 12 feet
• Width: 1 foot

Functional Features

• Rolls like a snake (inactive)
• Extends like an arm (active)
• Connected to smoke channels

Air Intake

• 82 linkas of fresh air enters

👉 Explanation:
The Shundaala acts as a directional exhaust system. The Shastra clearly states:

👉 “Direction of dhūma flow determines direction of movement.”

This resembles modern thrust vectoring systems used in advanced aircraft.

---

Vidyud Yantra (Electric System)

Key Concepts

• 32 methods of electricity generation
• Uses Saamyojaka method (combination-based generation)

Components

• 5 energy vessels
• Chemical mixtures
• Mercury
• Crystals
• Copper wiring

Storage

• Vessel made of Chapala-graahaka metal

👉 Explanation:
This describes a complex electro-chemical energy system. Although not explained in modern scientific terms, it shows a conceptual understanding of:

• energy generation
• storage
• distribution

---

Vaata-prasaarana Yantra (Vāta System – Air Propulsion)

Material

• Vaatamitra metal

Components

• Air pumping wheels
• Tubular poles
• Bellows system
• Air intake & exhaust pipes

Bellows Dimensions

• Length: 6 feet

Air Speed Output

• Naala airflow → 100 speed units
• Bellows airflow → 2000 prenkhana
• Top stambha airflow → 2600 prenkhana

👉 Explanation:
This system generates vāta (air force). The increasing speeds indicate pressure amplification, suggesting an understanding that higher airflow = higher propulsion.

---

Brihat Naala Stambha (Main Air Column)

Dimensions

• Height: 30 feet
• Width: 4 feet

Function

• Collects airflow from all systems
• Releases controlled air pressure

👉 Explanation:
This acts as a central airflow distributor, ensuring stability and balanced lift across the Vimana.

---

Chaturmukha Owshnya Yantra (Agni System – Heat Engine)

Material

• Kundodara metal

Capability

• Withstands 2000 degrees heat

👉 Explanation:
This is the thermal core of the Vimana. It generates agni (heat energy), which amplifies pressure and enhances propulsion efficiency.

---

Integrated Propulsion System

The Sundara Vimana operates using three combined forces:

Primary Forces

• Vāta (Air Force)
• Dhūma (Smoke Force)
• Agni (Heat Force)

👉 Explanation:
Unlike modern engines, this system uses multi-force propulsion, where each energy type contributes to motion.

---

Speed Calculations (Preserved Exactly)

Individual Speeds

• Dhūma speed → 2113 linkas
• Vāta speed → 2500 linkas
• Naala wind speed → 600 linkas
• Agni heat force → 3400 linkas

Final Speed

👉 400 yojanas (~3600 miles)

👉 Explanation:
The text attempts to mathematically combine forces. While not scientifically accurate, it reflects a systematic effort to quantify motion and speed.

---

Vimana Aavarana (Outer Covering)

Material

• Raajaloha metal

Structure Includes

• Compartments
• Machinery enclosures
• Central heating zone

👉 Explanation:
The covering protects the Vimana from:

• internal heat
• external environmental forces

---

Final Understanding

The Sundara Vimana is a multi-layered energy machine, combining:

• Vāta (air)
• Dhūma (smoke)
• Agni (heat)
• Vidyut (electricity)

into a single integrated system.

Conclusion

The aircraft described is known as the SUNDARA VIMAANA.

This Vimana represents a highly sophisticated conceptual framework where mechanical systems, energy processes, and structural design operate together. Rather than interpreting it purely as modern engineering, it should be understood as an ancient integrative model of flight, combining physical and energetic principles.
