摘要：
In order to research on performance of geared contra-rotating propfan engine, the model of gearbox and propfan were supplemented to the performance model of two spool turboprop, then the performance model of propfan engine were built by the introduction of new solver equation set. Through calculating, the performance parameters calculated at design point are similar with the calculation results of reference paper with the relative error no more than 0.1%. The current model can make it available that choosing pitch angles as controlled parameters of control schedule and the change of pitch angle has the biggest influence on performance parameters and rotating speed of corresponding propfan. Once one parameter of gas generator has been chosen as a controlled parameter, then selected two controlled parameters from pitch angles, rotation speeds of propfans, rotation speed of free turbine, 10 kinds of triple parameters control schedules combined all could be simulated in the model. It could be concluded that the performance model of propfan engine has good precision and convergence, which could be used to design control schedule and calculate performance of propfan engine. © 2019, Editorial Department of Journal of Propulsion Technology.
