aircraft-engine based units for ground application. SUBSTANCE: gas-turbine unit has inlet housing, compressor, and rotor speed transducer. Sensing element of transducer is mounted through bracket on housing. Transducer inductor is mounted on rotor shaft and is made in the form of ring with peripheral T-shaped toothed rim; t = 1.5-2.5 d, where t is width of toothed rim and d is diameter of transducer sensing element. The latter is reliably sealed to prevent its fouling. There are no intermediate parts between shaft and transducer. EFFECT: improved reliability and precision of rotor speed measurements. 2 dwg
