Inside the mast at the height of 4 feet above the peetha, three wheels should be provided, of 15½ feet diameter, with holes. The wheels above and below should be fixed with bolts, and unmoving. In order to revolve the middle wheel keys should be fixed outside on the mast, As there are holes in the wheels, as two wheels do not move, and as the middle wheel revolves in a group with the other two wheels, movement of air is, allowed or stopped by the turning of the key outside. Similarly at the height of 44 feet above the peetha three wheels corresponding to those below should be fixed and operated similarly.
4. Window dome:
The window dome should be of 15½ feet outside circumference. Its inside should be five feet wide and it should be 2 feet high. It should be fixed on the top of the mast.
5. Sun-crystal:
A sun crystal 7 feet round, and 2 feet wide and 2 feet in height should be fixed so as to crown the window dome. 10 feet above the bottom peetha, on a floor-board 3 inches thick, three floors or tiers should be built, each 14 feet high, with 3 inch floor-boards, the upper two floors being supported by pillars fixed at 10 feet intervals with screw joints and strong bolts. In the four corners 4 heating yantras should be fixed, 10 feet in circumference and 8 feet high. On the ground floor along the supporting pillars accommodation for passengers should be provided in the form of individual boxes.
On the second floor booths should be constructed to accommodate the anga-yantras, or the various mechanisms recommended for the safety of the vimaana. It should be 60 feet wide and 14 feet high with 3 inch thick ceiling board. The third floor should be 40 feet wide and 14 feet high. The partitioning boxes for passengers as well as the booths of the various machines should be divided off by railings starting from the hollow mast to the side walls in all the four directions.
Beneath the ground-floor board a 7 feet high cellar should be constructed. In it the several necessary yantras should be located. In the centre is the foot of the hollow mast. On the four directions from it 4 air pumping machines should be fixed. In order to stimulate them 4 steam engines also should be installed.
On the two sides of the vimaana two air expelling machines, and an air heater machine, and 2 machines to keep the heater supplied with air from outside, should be erected. In order to enable the wings on either side to spread and flap, proper hinges and keys should be provided for, safely fixing them to the sides of the vimaana, and for enabling them to fold and open easily.
The revolving tractor blades in the front should be duly fixed to the heating engine with rods so that they could dispel the wind in front and facilitate the passage of the vimaana. The wings are two, one on each side, very strongly fixed to the vimaana with bolts and hinges. Each wing should be fixed in a 11 foot scabbard up to 20 feet length, where it would be 10 feet wide, widening further up to 40 feet at the end of its 60 feet length, besides its. first 20 feet of scabbard length. The tail should be 20 feet long, and 3½ feet wide at the start, and 20 feet wide at the end.
6. The Air Blower and Heater
The length of the air-blower should be 15 feet, and width 3 feet. The naalaas or pipes should be 3 feet wide, and their outer circumference should be 4 feet. The rods and hinges and other equipment should be suitably prepared.
The vaatapaa yantra or air blower should be 12 feet long and 9½ feet wide. Inside it should be covered with circling wires. A pipe should be fixed inside, for air flow. By the hot oil fumes from the heated tank, the air becomes heated and should be passed into the owshmya yantra or heater, while the cold air from outside should also be let in. Tubes and fixings should be provided in the yantra. In order to emit the fumes of the oil flames to the outside, a 6 inches pipe should be fixed from the yantra to the foot of the mast.
Air blowers should be installed with 10 feet wheels to pump in fresh cold air from outside. To the east of the air machine should be placed a light burner in order to aid combustion of the oil. An electric generator provided with switches should light the burner. When the light is off the oil should be kept duly sealed. A rope should be tied to the tail joint, for the pilot to manipulate the fluttering of the tail to help the ascent or descent of the vimaana.
Similarly ropes should be tied to the hinges of the two wings, and passed to the pilot like reins, so that he might spread them out or close them as needed. Ten feet beneath the passenger floor of the vimaana, to a height of 2½ feet from the bottom plate there should be a cellar-like enclosure. The bottom of the vaatanaala mast should be fixed in its centre with firm screw joints. In this cellar should be located two oil tanks 15 feet by 9½ feet by 4 feet, with water jackets. Four bellows of 15 feet by 2½ feet by 6½ feet, should be provided for storing the air pumped in by the air-blowers, and letting it out as required.
And underneath, on all the four sides wheels of 7 feet circumference should be fixed for the movement of the vimaana on the ground.
