The cut section is constructed model is of light and strong metal showing air intake, axial flow, double stage compressor, fuel supply, combustion chamber, turbine rotor, jet thrust, exhaust etc.
Complete on base.
A series of models to demonstrate different gearing systems.
With transparent slideplates, the gears may easily be seen and where necessary there is an index on the primary and secondary shafts to show the change in the direction of rotation and the relative speed of rotation.
A simple three-speed and reverse-gear system using spur gears.
Reverse gear is obtained by interposing a small lay-shaft mounted pinion between the two main shafts.
Gear selection is by means of a short ball-ended lever.
Represents internal structure and operating principles of an air cooled two-stroke engine.
All parts in aluminium alloy.
Ignition is shown by means of a miniature bulb.
Carburetter and fuel supply also sectioned. Mounted on base with printed diagram showing working.
Two-Stroke Petrol Engine Four-Stroke Petrol Engine are also available.
For showing potential energy in a wound-up spring and its conversion to electrical energy by driving a dynamo and lighting a lamp.
May also be used to wind up a weight on a cord showing the change from potential energy to kinetic and back to potential in the raised weight.
The steel shaft carries a clock spring with a free wheel device and winding ratchet, also an aluminium 'V' pulley 56 mm.
diameter.
One end of the shaft overhangs the base for use as line shaft when winding up a weight.
Dimensions 220 x 100 x 100 mm.
high Supplied complete with driving belt.
For use as a water turbine to drive a generator producing electricity or for use as a pump driven by a motor and raising a head of water to produce potential energy.
The rotor has eight 'bucket' blades and is housed in a block turbine chamber with a clear Perspex front.
Two inlet tubules (for turbine and pump operation respectively) and one outlet tubule are provided and the shaft carries a 15 mm.
diameter pulley.
With driving belt.
