Recuperative descent at altitude 600m

 

Liftoplane: recuperative descent at altitude 600m RSI: recuperative descent at altitude 600m

The time scaling is 1:10

During this operation, the rotors have a moderate backward winding speed of about 11.6 m/s, providing a power of 42.7 kW, which is used to recharge the accumulators. The aircraft is not accelerating at all in any direction, having a horizontal speed of 48.19 m/s and a vertical descending speed of 11.11 m/s. Inflow is only 1.80 m/s. The aircraft operates like a lift going down at a speed of 7.31 m/s under a gliding wing with the equivalent LDR of 12.8. The aircraft is handled by using the biangular handling based on angles of attack with values of 5.0 and -1.7. The rotors have a PGS-state (0.7, 32.7, -5) with the high positive gain.
