AMT Olympus
AMT Netherlands
AMT Netherlands designs and manufactures small gas turbines for the propulsion of :
- target drones,
- radio-controlled flying aircraft,
- experimental aircraft development,
- full size gliders.
The original Olympus design was redesigned in 2004 to the HP version, in 2010 the engine is converted to a direct kerosene starting system.
The engine is highly used in the "model jet scene" but also professionals are using the Olympus HP. A spinoff of the Olympus HP is being certified by EASA for the use as a "bringing home device" for a full size glider. For universities a "special" layout is available with measuring points.
The Olympus engine has been constructed from a single radial compressor and an axial turbine.

The time required for the turbine to spool up and down is influenced by the low mass of its axial turbine Wheel :
- from min. RPM to max. RPM in less than 4 seconds
- from max. RPM to min. RPM in less than 2 seconds.
The combustion chamber is of the annular type, which is provided with a unique low pressure fuel system, developed by AMT.
From this same fuel system both hybrid bearings are also lubricated. A separate oil supply for lubrication is therefore no longer necessary.
The turbine is protected by means of a microprocessor controller (ECU) that regulates the maximum turbine performance within the software limits. The ECU is fully automatic and needs no adjustment
