A comparison of simulations are performed using both steady RANS with an actuator disk model to represent the propellers and URANS with full rotating blade geometry, for the Clean Sky 2 flying test bed 2, which is a regional turboprop with co-rotating propellers. The simulations are performed for a cruise configuration at Mach 0.2 and a Reynolds number of 11.933million for a range of angles of attack and side slip angles from zero to 20 degrees and 25 degrees respectively. The generation of the database for the actuator disk model is explained, along with the calibration of the blade angle to give a specified thrust. Aerodynamic coefficients for both the airframe and the propellers are extracted and compared with wind-tunnel data from an atmospheric wind-tunnel test undertaken in a previous Clean Sky 2 project (ReLOAD)
