thrustpayload
Thrustpayload is a term occasionally used in aerospace engineering to describe a metric relating the thrust produced by a propulsion system to the mass of payload it is intended to accelerate. It is not a standard term in published aerospace nomenclature, and its precise definition varies by designer or project.
Definition: In many informal usages, thrustpayload is defined as TP = T / m_payload, with units of newtons
Applications: Thrustpayload can be used in early design studies to compare propulsion options for a given payload,
Limitations: The metric omits critical factors such as propellant mass, vehicle structure, staging, gravity and drag
