Cruise at altitude 4016m

 

Liftoplane: cruise at altitude 4016m RSI: cruise at altitude 4016m

The time scaling is 1:10

During this operation, the rotors have a low forward winding speed of about 9.4 m/s, consuming a power of 27.2 kW. The aircraft is not accelerating at all, having a speed of 62.84 m/s. The inflow decreased somewhat to 1.98 m/s. The aircraft operates like a lift going up at a speed of 4.63 m/s, compensating for the sink of a gliding wing above it with the equivalent LDR of 13.7. The propulsion efficiency increased to 99.87 percent. The aircraft is handled by using the biangular handling based on angles of attack with values of 3.1 and 0.0. The rotors have a PGS-state (1.0, -14.0, -4) with a bit decreased pitch and a somewhat decreased magnitude of the negative gain and skew. Variations in the skew are used for a fine-tuning of the horizontality of the flight path.
