Fig. 10From: Flight simulation from takeoff to yawing of eVTOL airplane with coaxial propellers by fluid-rigid body interactionSnapshots of flow fields (Isosurface of velocity magnitude \(10 \mathrm {~m/s}\)) around the aircraft during takeoff in the case where the target altitude is \(12\mathrm {~m}\): left at \(t = 0.72 \mathrm {~s}\), right at \(t = 1.76 \mathrm {~s}\). Wind of \(10 \mathrm {~m/s}\) reached a maximum distance of \(16.9\mathrm {~m}\) away from the center of the aircraft (One unit of ground scale is \(2\mathrm {~m}\))Back to article page
