Definition

A constant parameter α in the fuel-optimal control model governing the rate of propellant mass depletion, appearing in the mass equation dm/dt = -α||T||. It is determined by the engine specific impulse and directly relates thrust magnitude to fuel consumption rate.

Application Value

This concept is fundamental to cislunar orbital mechanics and mission analysis, providing essential theoretical support for trajectory design and operational planning.
