fit_aero — DRIVE `ball` op

• Data kinds: signal × points × table → table

• Call: import fullseye as fs; fs.ledger.fit_aero(t, p, omega, bp: 'dict', *, iters: 'int' = 15, dt: 'float' = 0.001) -> 'dict' (to call the implementation directly, import ballistics; ballistics.fit_aero(t, p, omega, bp: 'dict', *, iters: 'int' = 15, dt: 'float' = 0.001) -> 'dict'; from the registry, opsdrive.get("fit_aero"))

Usage

> This operator's description has not been translated yet. The original text follows as it is.

軌跡から 空力係数も 同定する: (p₀, v₀, C_d, C_L) の 8 パラメータを Gauss–Newton(ω は既知、C_L は定数として当てる)。

抗力は速さの 2 乗、マグヌスは ω × v なので、直線的でない軌跡(スピンあり・十分な長さ)でないと C_L は決まりにくい

(`rms と一緒に cond = ヤコビアンの条件数を返すので、それで判る)。返り値 {"p0", "v0", "cd", "cl", "rms", "cond", "iters"}`。

真値の軌跡(C_L 定数で作った)なら 1e-6 で戻る(門)。
