Abstract:Fuel flow accurate measurement has an important impact on the aircraft engine performance determination. Compared with other types of traditional flowmeters, dual-rotor turbine flowmeter has many merits, and also a wide range of engineering application prospects. This paper presented the operation principle and calculation method of dual-rotor turbine flowmeter. Combined with the dual-rotor turbine flowmeter flight test data of certain aircraft engine, the calculation results were obtained. Compared with the supplier’s results, it showed that the two matched well and the calculation method was verified.
