DANAUS

It has a 6.03'Ø 8-blade lift-rotor on the top, a 3.42'Ø 6-blade pushing thrust-rotor on the rear and 1.33'Ø 5-blade side-rotors built into each its four impact landing wheels, all driven by electric motors independently. A 120 lbs LiPo battery package-built into the under carriage fixed wings-powers the drive motors... The landing wheels have elastomeric fan blades as spokes to absorb a 5G landing impact. Between the wheels and the fixed wings, four flaps assist in aircraft attitude and flight control, including hovering for counter-torque by opposing angles at left and right. The wheel rotors counter the lift-rotor's torque exerted on the fuselage as well. The noise-to-ground is limited by very low rotor speeds of long-chord thin-airfoil rotor-blades (e.g., NACA 7501 on the lift-rotor)... Upon reaching cruising altitude, the thrust-rotor is gradually powered up and the lift-rotor is powered down. The vertical-horizontal flight transitions are therefore smooth. During cruising at..
