Ascending to cruise altitude at 3900m

 

Liftoplane: ascending to cruise altitude at 3900m RSI: ascending to cruise altitude at 3900m

The time scaling is 1:10

During this operation, the rotors have a somewhat increased forward winding speed of about 13.5 m/s to compensate for the decrease in air density, consuming a power of 58.2 kW. The aircraft is not accelerating at all in any direction, having a horizontal speed of 59.38 m/s and a vertical speed of 5.04 m/s. Inflow increased somewhat to 2.08 m/s. The aircraft operates like a lift going up at a speed of 9.91 m/s under a gliding wing with the equivalent LDR of 12.6. The propulsion efficiency increased to 99.55 percent. The aircraft is handled by using the biangular handling based on angles of attack with values of 6.0 and -0.2. The rotors have a PGS-state (1.4, -18.9, -10) with a bit increased pitch and a somewhat decreased magnitude of the negative gain.
