Roping Ari at Speed

Side view, to scale. She arrives at 79 km/h and has to get over a trolleybus on her own two wires. Four ways to do it. Three start from the pulled gait, hanging from her pole tips, with as little as she can: a tip brake alone, a tip brake with one pull of the poles, or no brake at all, a short flare and one pull. The fourth starts from the lifted gait, flying ahead of her tips: she drops out of it, ropes over the bus with hoop and circle, and swings back into flight. The playback stops at each key moment and shows its numbers.

Point-mass sketch, 4 kg, still air, every phase on the wire solved: a body on rigid poles pinned at tips whose speed along the wire follows simple rules, with wing lift and drag, flare drag, narrow-body drag and drag along the poles. From the pulled gait, the tip brake (for the flare kick, the flare) is the gentlest one that lands her tips 2.5 m ahead of the windscreen, found by scanning; the release gap keeps her behind the bus's collector shoes as she rises through the wire plane; her turn in the air is trimmed by up to a third. From the lifted gait, three numbers are tuned against targets (the tip brake in the drop, the tip brake in the circle, the run past cruise speed) and the gait itself is held by a small balance rule on her angle of attack. No pole bending, no wire sag, no gusts; whether her tips can grip the wire that hard is assumed.
