Flying Saucer
+
The air is being blown down through the blade and the
motor rotation locks the fan on the shaft. When the
motor is turned off, the blade unlocks from the shaft
and is free to act as a propeller and fly through the air.
If speed of rotation is too slow, the fan will remain on
the motor shaft because it does not have enough lift to
propel it. The motor will spin faster when the batteries
are new.
Description
Push the press switch (S2) until the motor reaches full
speed, then release it. The fan blade should rise and
float through the air like a flying saucer. Be careful not
to look directly down on fan blade when it is spinning.
If the fan doesn’t fly off, then turn the switch on and off
several times rapidly when it is at full speed.
Operation
Build the circuit as shown and place the fan on the
motor (M1). Be sure the “+” side of the motor is on the
left.
Assembly
!
WARNING: Moving parts. Do not
touch the fan or motor during
operation.
!
WARNING:
Do not lean over the motor. Fan may
not rise until switch is released.
Snappy says: This circuit is
similar to project 54 but
may launch the fan a little
higher. Project 54 has the
slide switches and more
blue snap wires; together
these add a slight amount
of additional resistance to
the circuit.
