poliastro2.math.threebody.flybys

Low level computations for flybys.

Functions

compute_flyby(v_spacecraft, v_body, k, r_p, ...)

Computes outbound velocity after a flyby and the turn angle.
poliastro2.math.threebody.flybys.compute_flyby(v_spacecraft, v_body, k, r_p, theta)

Computes outbound velocity after a flyby and the turn angle.

Parameters:

  • k (float) – Standard Gravitational parameter.

  • r_p (float) – Radius of periapsis, measured from the center of the body.

  • v_spacecraft (float) – Velocity of the spacecraft, relative to the attractor of the body.

  • v_body (float) – Velocity of the body, relative to its attractor.

  • theta (float) – Aim angle of the B vector.

Returns:

  • v_spacecraft_out (float) – Outbound velocity of the spacecraft.

  • delta (float) – Turn angle.
