GPT4 analysis is based on given prompts on sanskrit verses on Shakuna Vimana from Vimanashastra which are translated by GPT4 , natural language processing A I Model of OpenAI of Microsoft

Propulsion method :

Based on the translated verses, the propelling method used in this flying machine involves a wind-drawing mechanism that produces air and a set of four wind-drawing tubes. These tubes appear to generate and direct the air, creating propulsion for the flying machine. The verses also mention an external propelling tube and peg, which may be part of the overall propulsion system. The specific details of how the mechanism works are not explicitly described in the provided verses.  

Shape of the Aircraft:

Considering the bird-like shape described in the verses, a modern post-1900 aircraft that comes to mind with a similar design is the ornithopter. An ornithopter is an aircraft that flies by flapping its wings, imitating the flight mechanism of birds. While most modern aircraft do not use this method, the concept of ornithopters has been explored and experimented with in various forms over the years, including some small-scale and experimental models.  

Note here Shakuna means bird in Sanskrit  

Resemblance to Modern Aircraft :

The verses provided seem to describe an ancient flying machine with some resemblance to modern aircraft principles. The mention of a propulsion mechanism using air or wind, as well as the reference to bird-like wings and the importance of balance and control, suggest some parallels with contemporary aviation principles. However, the technology and methods described are quite different from modern aircraft, which use engines to generate thrust and have fixed wings for lift. While the verses do not directly correspond to any specific modern aircraft, they do offer an intriguing glimpse into early ideas about flight and aviation.  

Fuels used in the Shakuna Aircraft :

In the verses provided, oil and electricity seem to play a role in the operation of the described flying machine. The oil appears to be used for fueling a fire or providing a source of heat, as mentioned in verse 121: "तैलप्रज्वलनार्थाय दीपचुल्ली प्रतिष्ठिता" (For the purpose of igniting the oil, a lamp or flame is established). This suggests that the machine might have used some form of heat or combustion process, possibly to generate power or propulsion.

In verse 122, there is a mention of विद्युद्यन्त्र (vidyudyantra), which can be translated as an "electricity device" or "electrical mechanism": "तस्मिन् दीपप्रतिष्ठार्थं मग्न्युत्पत्त्यर्थमेव तु। विद्युद्यन्त्र स्थापित स्यात्कीलकैस्सुदृढ यथा" (In that, for the purpose of establishing a flame and generating fire, an electrical device is installed and fastened securely with pegs). This indicates that electricity was considered an important component in the operation of the flying machine, possibly for igniting the oil or for other control or power generation purposes.

These descriptions, while not directly corresponding to modern aircraft technologies, suggest that the use of energy sources such as oil and electricity was an important aspect of the operation of this ancient flying machine.

Design of the aircraft :

Based on the verses provided, it is difficult to create a precise visual representation of the aircraft, but we can gather some general ideas about its appearance and features.

1. Measurements: The verses mention various measurements for different components of the aircraft. For instance, verses 129-130, 133, and 135-136 discuss the dimensions of specific parts. These descriptions might suggest a relatively compact or small-sized aircraft.
    
2. Propulsion technology: The aircraft appears to use a combination of wind (or air) propulsion and a heating mechanism fueled by oil. The verses mention a "wind attraction device" (वाताकर्षणयन्त्र) and an "electricity device" (विद्युद्यन्त्र) which could be related to the propulsion system. Moreover, there is a reference to the use of oil to generate heat or combustion, which might also be a part of the propulsion mechanism.
    
3. Fuel: Oil seems to be an essential component of the flying machine, as it is used to generate heat or power. The role of electricity is also mentioned, possibly as a means to ignite the oil or to control other aspects of the aircraft's operation.
    

Considering these factors, the aircraft might resemble a bird-like structure, with a compact size, and wings or other elements designed for air propulsion. The aircraft could have an oil-fueled heating or combustion system, possibly combined with an electrical system for ignition and control purposes.

However, it is important to note that these descriptions are based on ancient Sanskrit verses and might not directly correspond to modern aircraft technologies or designs. The actual appearance and functioning of such an ancient flying machine would likely be quite different from contemporary aircraft.

Units mentioned in design of the Shakuna Aircraft :

The units mentioned in the translated verses include:

1. Vitasti (a unit of length, approximately 12 inches or 30.48 centimeters) - used to describe various dimensions of the aircraft.
    
2. Angula (another unit of length, approximately 0.75 inches or 1.905 centimeters) - used in describing specific measurements of certain parts of the aircraft.
    

These units were commonly used in ancient Indian texts to describe measurements and dimensions.
