INTRODUCTION
• Gasoline and other petroleum products are non-renewable
sources which will very soon be extinct. Hence there rises a
need to find alternative solutions to power vehicles in the near
future. This is the basis on which our project is based on.
• Compressed air is used to power turbines directly at lower
speeds and with the help of a vortex chamber in case of higher
speeds which will in turn help to power the wheels.

COMPONENTS
• Pressurized tanks
• A centrifugal compressor
• A vortex flow chamber
• A primary turbine
• A secondary turbine
WORKING• At low speeds the compressed air from the pressurized air tanks
is used to run the secondary turbine. The power developed by
this turbine is used to power the vehicle. A part of the power
developed by the secondary turbine is used to run the compressor
which feeds compressed air to the primary turbine through the
vortex chamber.
• At higher speeds, the air coming to the primary turbine through
the compressor and the vortex chamber will have optimum
flow characteristics to run the turbine at a speed sufficient enough to
power the vehicle. At this point the primary turbine alone will be
powering the motion of the vehicle.
• Due to the constraints of time and costs we plan to concentrate
more on the design at lower speeds.
• The compressed air from the cylinder acts as an input to the
turbine.
• Here we plan to use a ‘Tesla Turbine’ as it is simple in
construction and lighter in weight
METHODOLOGY
• We first plan to design a Tesla turbine and then fabricate the
same.
• After fabrication we experimentally test the Tesla turbine for
various loading conditions and pressure output from the
compressor and optimize the performance of the turbine.
• After optimizing the performance of the turbine we design the
variable stroke pump.
• The torque converter used to get the required torques at the
wheels is also designed.
• The gears required to reduce the speed are designed.
• The chassis is designed and a stress analysis is carried out for
the same.
ADVANTAGES• Air cars are emission-free at the exhaust.
• Compressed air engines reduce the cost of vehicle production,
because there is no need to build a cooling system, spark plugs,
starter motor.
• Expansion of the compressed air lowers its temperature, this may
be exploited for use as air conditioning.
• Air is used as the fuel, which is a renewable source of energy.
• The rate of self-discharge is very low opposed to batteries that
deplete their charge slowly over a period of time.
EXPECTED OUTCOME
• To successfully design and fabricate a tesla turbine and optimize
the performance:
• To successfully design a system which runs on power from a
tesla turbine driven by compressed air at lower speeds.
• To obtain optimum results of power and torque.
• A brief report on the use of vortex chamber driven turbine at
higher speeds as a future prospect.
