Disclosed are a method and a device for estimating an air speed using a propeller performance analysis method. The method for estimating an air speed using a propeller performance analysis method according to an embodiment of the present invention comprises: a step of calculating an equivalent lift force coefficient and an equivalent drag force coefficient as propeller equivalent aerodynamic data in relation to a flight vehicle of a propeller propulsion method; a step of writing each of the equivalent lift force coefficient and the equivalent drag force coefficient into an equivalent lift force coefficient polynomial expression and an equivalent drag force coefficient polynomial expression which are a function of an angle of attack; and a step of estimating the air speed of a flying object during the flight by finding an advance ratio corresponding to an input shaft power coefficient of the flying object with the equivalent lift force coefficient polynomial expression and the equivalent drag force coefficient polynomial expression.
