Flybys

poliastro.threebody.flybys.compute_flyby(v_spacecraft, v_body, k, r_p, theta=<Quantity 0. deg>)

Computes outbound velocity after a flyby.

Parameters:

• v_spacecraft (Quantity) – Velocity of the spacecraft, relative to the attractor of the body.
• v_body (Quantity) – Velocity of the body, relative to its attractor.
• k (Quantity) – Standard gravitational parameter of the body.
• r_p (Quantity) – Radius of periapsis, measured from the center of the body.
• theta (Quantity, optional) – Aim angle of the B vector, default to 0.

Returns:

• v_spacecraft_out (~astropy.units.Quantity) – Outbound velocity of the spacecraft.
• delta (~astropy.units.Quantity) – Turn angle.
