TU R BIN E
-Don Hyzer, me'46
THE    gas turbine has been a natural development fol-
   lowing the gasoline engine, just as the steam turbine
followed the steam engine. Its actual development was
started in the eighteenth century, but it never came into
its own until recent years.
  The oil burner in the home with modifications is a type
of gas turbine which can be used to show its operation. A
typical oil burner has an electric motor which drives an
air blower. The air and fuel come together in the firebox
to produce a flame which heats the boiler. In the gas tur-

bine unit, instead of the gases escaping they go into the
turbine which replaces the boiler and produce power. The
power is used to operate the blower and also a generator
which replaces the motor. The generator is used as a
motor when starting the unit.
  The gas turbine has the advantage over other engines
in that it operates at higher temperatures. This advantage
is because in "heat engines" if the input temperature is
high the efficiency is high, other factors remaining equal.
The fact that it is very simple with no recipitating parts
          puts its above its mate, the gas engine. Besides
          there is no chance of it freezing up, because of
mosie    the absence of freezable liquids. Odd it is that
jto C. k  the colder the outside temperature becomes the
          more efficiently the machine runs. This fact
          makes it especially applicable for use on air-
          planes.

THE ELEMENTARY GAS TURBINE
  Many turbocharged diesel locomotives have
been built, but the only one built using the gas
turbine in place of the diesel is in Switzerland.
The gas turbine is being used in industries
where hot gases are given off because of some
manufacturing process.
  A central power station using a gas turbine
as the power unit was built in Switzerland by
Brown, Boveri, & Company. It is installed as
a bombproof unit to furnish power in case of
an emergency. The advantages are that it is
cheap, light, simple in design, small, and is not
dependent on any water supply. It has also
shown its value on relieving peak loads, al-
though it cannot yet compete with the modern
steam plant on base loads.
  One of the greatest developments of the gas
turbine has been for supercharging airplane en-
gines, a subject which will not be covered here.
Its use as a prime mover and stationary engine
is becoming more widespread with those in use
showing good qualities which insure its growth.
