FIELD: engines and pumps.SUBSTANCE: invention relates to systems of gas turbine engine rotor RPM measurement with circulating lubrication system of bearing supports, including oil supply and breathing systems, in particular to systems for measurement of ground use gas turbine engine rotor RPM. Technical result is achieved by fact that on turbo compressor rotor, namely to fastening nut compressor turbine, light-reflective coating is applied, which is illuminated with laser light emitter, which reflection is reflected on receiving device, which signal is supplied to reading electronic converter.EFFECT: higher reliability and easy servicing micro gas turbine rotor RPM measurement system with engine based on turbo-compressor of internal combustion engine.1 cl, 2 dwg |
