ball op• Data kinds: table → table
• Call: import fullseye as fs; fs.ledger.thrust_ode(p0, v0, thrust, bp: 'dict', t_end: 'float', dt: 'float' = 0.001) -> 'dict' (to call the implementation directly, import ballistics; ballistics.thrust_ode(p0, v0, thrust, bp: 'dict', t_end: 'float', dt: 'float' = 0.001) -> 'dict'; from the registry, opsdrive.get("thrust_ode"))
• GPU: none (CPU reference implementation only)
RK4 for gravity + drag + a constant specific thrust (thrust per unit mass [m/s²], fixed in direction and magnitude in world coordinates). No spin (ω = 0). Returns {"t" (N,), "p" (N, 3), "v" (N, 3)} (t = 0, dt, …, ≤ t_end). With a zero thrust it matches flight_ode (ω = 0) to 1e-12, and in vacuum (rho = 0) it matches the closed form p₀ + v₀ t + ½ (a_T − g ẑ) t² to 1e-9 (gate). The smallest model for "almost a rocket" footage; a thrust fixed to the body that turns with it is only approximated (the shorter the segment, the better). t_end / dt must be finite numbers, bp the table from ball_params (a missing key, a non-finite value or zero mass is a ValueError), and the step count t_end / dt is capped at 5×10⁶ (this stops a t passed in ms instead of seconds).
Empty input (thrust with 0 elements) raises ValueError.
