Abstract
An apparatus integrated with micromachined (a.k.a. MEMS, Micro Electro Mechanical Systems) silicon sensor to measure air flow velocity on targeting correction for projectiles arms is disclosed in the present invention. The air flow velocity component perpendicular to the travel direction of bullets with respect to projectile arm body (e.g. bullets, shells, or arrows) has main effect to the targeting accuracy. Such effect is pretty much determined by the wind speed and the projectile travel distance. The integration with MEMS mass flow sensor has made the invented apparatus possible to be compact, low power consumption, low cost and high accuracy. The low power consumption characteristic of MEMS mass flow sensor is especially crucial for making the apparatus of present invention feasible by battery operated.
