sathishramyen | Every
scholar knows the Vaimanika Shastra, a collection of sketches the core
of which is attributed to Bharatvaj the Wise around the 4th century B.C.
The writings in the Vaimanika Shastra were rediscovered in 1875. The
text deals with the size and the most important parts of the various
flying machines. We learn how they steered, what special precautions had
to be taken on long flights, how the machines could be protected
against violent storms and lightning, how to make a forced landing and
even how to switch the drive to solar energy to make the fuel go
further. Bharatvaj refers to no fewer than 70 authorities and ten
experts of Indian air travel in antiquity!
The description of
these machines in old Indian texts are amazingly precise. The difficulty
we are faced with today is basically that the texts mention various
metals and alloys which we cannot translate. We do not know what our
ancestors understood by them. In the Amarangasutradhara five flying
machines were originally built for the gods Brahma, Vishnu, Yama, Kuvera
and Indra. Later there were some additions.
Four
main types of flying Vimanas are described: Rukma, Sundara, Tripura and
Sakuna. The Rukma were conical in shape and dyed gold, whereas the
Sundata were like rockets and had a silver sheen. The Tripura were
three-storeyed and the Sakuna looked like birds. There were 113
subdivisions of these four main types that differed only in minor
details. The position and functioning of the solar energy collectors are
described in the Vaimanika Shastra. It says that eight tubes had to be
made of special glass absorbing the sun’s ray. A whole series of details
are listed, some of which we do not understand. The
Amaranganasutradhara even explains the drive, the controls and the fuel
for the flying machine. It says that quicksilver and ‘Rasa’ were used.
Unfortunately we do not yet know what “Rasa’ was.
Ten sections deal
with uncannily topical themes such as pilot training, flight paths, the
individual parts of flying machines, as well as clothing for pilots and
passengers, and the food recommended for long flights. There was much
technical detail: the metals used, heat-absorbing metals and their
melting point, the propulsion units and various types of flying
machines. The information about metals used in construction name three
sorts, somala, soundaalika and mourthwika. If they were mixed in the
right proportions, the result was 16 kinds of heat-absorbing metals with
names like ushnambhara, ushnapaa, raajaamlatrit, etc. which cannot be
translated into English. The texts also explained how to clean metals,
the acids such as lemon or apple to be used and the correct mixture, the
right oils to work with and the correct temperature for them.
Seven
types of engine are described with the special functions for which they
are suited and the altitudes at which they work best. The catalogue is
not short of data about the size of the machines, which had storeys, nor
of their suitability for various purposes.
This text is
recommended to all who doubt the existence of flying machines in
antiquity. The mindless cry that there were no such things would have to
fall silent in shame.
