Method of controlling aerodynamic characteristics of spiked flying object, and spiked flying object

摘要

To provide a method of controlling the aerodynamic characteristics of a spiked flying object with an easy method without using a complicated variable mechanism or fluid energy supply system. A plurality of injection holes that are communicated with an internal channel are disposed on the front portion of a hollow shaft, and a valve for opening/closing an outlet section is disposed on the outlet section of the hollow shaft, to change either or both the opening/closing speed Vf of the valve and the duty ratio DR of the valve by means of a valve driver, whereby the aerodynamic characteristics of the hollow shaft are suitably controlled.
