Novel diagnostic methods for performance of a launch vehicle are disclosed. A method may include computing energy for a pre-flight trajectory of a vehicle using angular momentum of the vehicle, and comparing a difference in energy between the energy for the pre-flight trajectory of the vehicle and energy for a flight trajectory of the vehicle.
Keywords: angular momentum, diagnostic, launch
