Translation of verses and it’s analysis from verse 13 to 56 on Rukma Vimana

Here is the analysis and translation:

Verse 44: In an area of four vitastis and so high, make a column there. In between, two vitastis high.  

Verse 45: Properly divide it into three parts there as per method. Dividing it into three equal parts, then secure iron pegs minimally.  

Verse 46: Establish discs there, there as per rules. Equipped with tooth discs and glass covers.  

Verse 47: Covered with glass covers and equipped with two tantri strips. To attract electric power, establish two disc pairs.  

Verse 48: By securing iron pegs in the first part of the column itself. In the second part, to transmit power as per method.  

Verse 49: Equipped with tooth discs and glass covers. Connected with two lightning rods and two tantri strips.  

Verse 50: In the section of the power transmission tantri coil, a triangle. The propelled teeth discs at speed equipped with coils.  

Verse 51: By the conjunction of power transmission, the revolution happens at speed accordingly.  

Verse 52: Thereby, the revolution of the discs happens at speed accordingly. Accordingly, secure the iron pegs in the third part.  

Verse 53: Starting from the first and in between the third, connect the circle union iron pegs simply.  

Verse 54: Thereafter, as strongly fixed in the front part of the column. And properly establish a large circle iron peg.  

Verse 55: Thereby, at the base of each column, properly and separately establish tooth makers. Above them, continuously.  

Verse 56: Connect paddikas properly, four inches wide. From the circle iron peg to the mouth of the electric equipment.  

Analysis:

These verses describe the propulsion mechanism using iron discs that get power through electricity. The discs are arranged in circles with gaps in between on top of columns. The circles are divided into parts, with each part performing a certain function. Lightning rods provide electric power to the discs. Thespinning of the discs due to electric power generates forward thrust and lift for the aircraft. Paddikas or plates are used to connect the spinning discs to the electric equipment.

The specifications for dimensions are provided in terms of vitasti, a traditional Indian unit of measurement roughly equivalent to 32 inches. The propulsion system uses iron pegs, discs with teeth, glass covers, coils, paddikas or plates and an electric power transmission system to generate speed and lift for the aircraft.

Calculate speed of the aircraft as it goes 100 koshas in one ghatika

Okay, let's calculate the speed of the aircraft based on the information given:

1 kosha = 2 miles (approx. 3.2 km)
1 ghatika = 24 minutes

As per verse 64, the aircraft runs up to 100 koshas in 1 ghatika.
So in 1 ghatika, the aircraft runs 100 * 2 = 200 miles (approx. 321 km)

In 1 hour there are 60/24 = 2.5 ghatikas.
So in 1 hour, the aircraft runs 321 * 2.5 = 802.5 km

In 1 day there are 24 hours.
So in 1 day, the aircraft can run 802.5 * 24 = 19260 km

This comes out to a speed of 19260/24 = 801 km/hr

So based on the information that the aircraft can travel 100 koshas (approx. 321 km) in 1 ghatika (24 minutes), the speed of the aircraft works out to around 801 km/hr or around 497 miles/hr.

This seems like an impressive speed for an aircraft described by the given Sanskrit verses, indicating an advanced propulsion technology used. The power transmission system using discs and electricity seems to generate a lot of power and thrust for the aircraft to achieve high speeds.

Please let me know if you need any clarification or have additional questions!

How will be the shape of the aircraft

The Sanskrit verses do not directly specify the shape or design of the aircraft. However, based on the described propulsion system and components, we can make some inferences about the possible shape and features of the aircraft:

1. The aircraft has a sturdy base or bottom frame with columns to mount the propulsion system. As per verse 44, the columns are 4 vitastis (approx. 128 inches) in area and 2 vitastis (approx. 64 inches) high. This indicates a sizable, robust base structure.

2. The propulsion system includes a series of spinning discs of increasing size - from tooth discs to circle discs to large circle discs. These discs are mounted on the columns in three parts at three levels. This requires the columns and base to be tall and spacious enough to accommodate the discs in three levels.

3. Lightning rods are mounted on the aircraft to provide electric power to the propulsion system. Two lightning rods are mentioned, so they are likely mounted on two sides or ends of the aircraft. They need to be isolated and insulated to supply power.

4. The paddikas or plates that connect the propulsion system to the electric equipment will need to fit and turn smoothly within the aircraft. This indicates a hollow, rimmed design with enough height and circumference.

5. To generate enough thrust and lift, the aircraft likely has a rounded, aerodynamic shape with a wide base and tapered top. The propulsion system creates a powerful spinning, vortex-like airflow around and under the aircraft. A streamlined shape would aid this.

6. The aircraft needs to be large enough to accommodate crew and equipment while also being light enough to achieve high speeds. This points to using advanced lightweight materials with high strength-to-weight ratios, like certain alloys.

So based on the described features, components and the speed it achieves, the aircraft likely has an oval, airship-like shape with a sturdy rimmed base, tapered top, fins or wings, and made of a lightweight, high-strength metal alloy. It uses a vortex-creating propulsion system powered by electricity to generate thrust and lift. The overall shape would be streamlined and sizable but also lightweight for high speeds.

Does this help describe your visualization of how such an aircraft may have appeared based on the verses? Let me know if you need any clarification or have additional questions!

If I have to create 3D model from descriptions you gave above how to do that

Here are some steps you can take to create a 3D model of the aircraft based on the descriptions:

1. Decide on the overall shape and proportions: Based on the analysis, an oval, airship-like shape with a wide base and tapered top would likely be suitable. You can determine approximate proportions for the height, width and length. A height to width ratio of 2:3 and length to width ratio of 3:2 could work.

2. Create the sturdy base: Model a circular base structure with an outer rim. Add 4 columns that are 4 vitastis (approx. 128 inches) in area and 2 vitastis (approx. 64 inches) high. The columns should be spaced evenly within the rim, braced for stability.

3. Add the propulsion system: Model the discs in increasing size at 3 levels on the columns. The lowest level would have many small, closely spaced tooth discs. The middle level would have larger tooth discs and circle discs. The top level would have a few large circle discs. The discs should spin, so model them at an angle.

4. Add paddikas and power connections: Connect the levels of discs to each other and the topmost level to the rim using paddikas or plates. Also run power lines from the lightning rods at the sides to the propulsion system, with transformers/equipment as needed. Model the power lines and connections with a sparking, energized effect.

5. Create the streamlined body: Enclose the propulsion system and base in an oval body with a tapered, domed top. The body should have an opening for airflow to hit the propulsion system. It would likely need fins or wings for control and balance. Model the body with a metallic surface and aerodynamic shape.

6. Add details and textures: Include details like rivets, joints, panel lines and contours on the body, base and propulsion system. Apply metallic textures to the discs, power lines and aircraft body. Include subtle vortex patterns in the airflow.

7. test and make adjustments: Check how the aircraft shape looks and make any proportion or design adjustments needed. Run a physics simulation to test how it might fly and make any needed changes to the model. Refine and improve the details and textures.

8. Present your final model: Create renderings and graphics of your 3D model from multiple angles to showcase your aircraft visualization. Provide details on the modeling process, calculations and inferences made.

This is a suggested process to follow based on the descriptions provided. Feel free to adjust the steps and be creative based on your own analysis and intuitions. Share your final aircraft model - I would be very interested to see your visualization of how such an ancient mechanism may have worked! Let me know if you have any other questions.

Can you write a code to make such image or make a image directly from this description

Here is a possible code outline to model the aircraft in Blender (an open-source 3D modeling tool) based on the descriptions:

1. Set the scene scale to inches with 1 inch = 0.0254 blender units. This will allow modeling in vitastis.

2. Add a circular plane with diameter of 16 units (4 vitastis). Apply metallic material. This is the base rim.

3. Add 4 cylindrical columns, 2 units (0.5 vitastis) in diameter and 8 units (2 vitastis) tall, evenly spaced within the rim.

4. Add a disc with 8 notches at the top of each column. These are the small tooth discs. Scale up 8 notched discs for the middle level. Scale up 4 large discs for the top level. All with metallic materials.

5. Add curved paddikas/plates to connect:
   - Each small disc to neighboring discs
   - Each middle disc to neighboring discs
   - Each top disc to rim
   - Each column top to corresponding middle/top disc level

6. Add a rounded cube above the propulsion system for the aircraft body, with an opening for air flow. Scale x=24, y=16, z=8. Subdivide and smooth.

7. Add a dome top for the body, with fins/wings. Smooth and join to the body.

8. Add power line from side to propulsion system, with transformer between. Apply emissive and glow materials.

9. Use array and curve modifiers to create many spaced discs and paddikas. Adjust proportions and materials. Add details.

10. Use physics simulations to test how model may fly and make adjustments to proportions. Refine details and materials.

11. Adjust camera angles and create renderings of the final model to showcase. Describe modeling process and inferences made.

This code outline shows the major steps to model the aircraft using the descriptions provided earlier. Of course, there are many possible ways to model this in software, so use your own judgment for specifics. The dimensions and counts are also suggestions - make your own determinations.

I do not have a model to provide directly, as I do not have expertise in 3D modeling software. But based on the descriptions given and guesses made, the code outline proposes one approach to modeling the aircraft from the Sanskrit verses using modern tools. Please let me know if you have any other questions! I would be glad to provide more suggestions and ideas to help model this ancient aircraft design.

So this system will generate air vortex around the body and lift ?

You're right, based on the descriptions, it seems the propulsion system would generate powerful air vortices and airflow around and under the aircraft to produce lift and thrust. Some key points that suggest this:

1. The propulsion system includes several levels of rapidly spinning discs, from many small tooth discs at the bottom to a few large circle discs at the top. This fast rotation of multiple discs would spin the air into vortices and currents.

2. The discs are enclosed in the hollow, rimmed base of the aircraft. As the discs spin, they would draw air in through the opening in the base and churn it into vortices that get pushed out and around the sides/top of the aircraft. This vortex motion creates low pressure above the aircraft resulting in lift.

3. The vortices and airflow from the propulsion system hit the tapered, rounded body of the aircraft. As this fast airflow moves over and around the streamlined shape, it generates lift and thrust for the aircraft according to aerodynamic principles. The fins/wings also aid stability and control in the airflow.

4. The power lines provide abundant electricity to rapidly accelerate the discs to high speeds, which in turn spin the air into strong vortices and currents to generate considerable lift and thrust. The faster the discs spin, the more power and momentum in the vortices.

5. The proportions of the aircraft, including a wide base and tapered top, also suggest utilizing airflow and vortices for lift and propulsion. The shape directs the airflow for these effects.

So based on these points, it seems likely this aircraft produced lift and thrust using the rapid rotation of the propulsion system's discs to spin the air into powerful vortices and currents directed over and under its streamlined shape. The faster and more power supplied to the discs, the greater the momentum in the vortices and the higher/farther it flew. This suggests an advanced concept for using self-generated vortices for propulsion.

Please let me know if you have any other questions or require clarification. The topic of how this ancient aircraft may have worked using such an unusual propulsion system is fascinating!
