Iron Man's Repulsor Flight.
What receives a repulsor’s opposite momentum?
What receives a repulsor’s opposite momentum?
Fit the assemblies, choose the inputs, then run the test.
An ordinary jet sends reaction mass backward and pushes the rig forward. Exhaust speed trades mass flow against power demand. Tilting changes lift and torque. A separate fictional reactionless mode records missing external momentum and unknown power; it cannot pass the ordinary-physics challenge.
Clamped force-balance rig, not free-flight simulation. 100 kg test mass, three identical-tilt jets. Palm carries 20% thrust; boots each 40% plus/minus the balance percentage. Boot lever 0.35 m, palm height 0.8 m. Assumed exhaust speed and 65% kinetic efficiency; ambient pressure term omitted. Reactionless mode has unspecified power and requires an unexplained external momentum reservoir.

Support 100 kg, keep torque within 20 N·m and input power below 1 MW using reaction jets.
Balance the three thrust units and identify their reaction momentum.
