Before touchdown at altitude 0.4m

 

Liftoplane: before touchdown at altitude 0.4m RSI: before touchdown at altitude 0.4m

The time scaling is 1:10

During this operation, the rotors have a high forward winding speed of about 19.9 m/s, consuming a power of 34.0 kW. The aircraft is decelerating horizontally at a rate of about 0.216g, having a horizontal speed of 22.11 m/s. At the same time, the aircraft has a vertical descending speed of 0.53 m/s, which is decreasing at a rate 0.077g. Inflow increased to 3.78 m/s. The aircraft operates like a lift going up at a speed of 5.25 m/s under a gliding wing with the equivalent LDR of 2.1. The aircraft is handled by using the biangular handling based on pitches with values of -14.6 and 58.0. The rotors have a PGS-state (17.0, -60.1, -5) with the gradually increased magnitude of the negative gain.
