Propulsion thrust equation

WebbThrust equation of Jet propulsion 2.1 Introduction:- The designer of an aircraft engine must recognize the differing requirements for take-off, climb, cruise, and maneuvering, the relative importance of these being different for civil and military applications and for long- and short-haul aircrafts. WebbF = 2 R S A c sin 2 θ = 9.113 × 10 − 6 R A D 2 sin 2 θ Where, F is the thrust; R is the fraction of incident light; D is the distance from the Sun in astronomical units; S the solar flux in W / m 2; c the speed of light; A the sail area in m 2 and θ the sail tilt angle. Does this formula calculate instantaneous thrust?
