Abstract: A system and method for determining the wind force along the planned trajectory of a projectile are disclosed herein. A drone is flown along the expected path of the trajectory along a set heading. The drone is programmed to maintain the heading. As wind forces act upon the drone during its flight, the drone's electronic stability system provides automatic power and directional control to one or more motors that control the rotors and propellers that keep the drone aloft. By monitoring the changes in motor or drone state information over time in response to wind forces, the wind can be determined at various locations along the flight path. This information can be provided to a ballistics calculator to determine the launch heading of the projectile.

Abstract: The apparatus includes a gas diffuser plate having an integral heat pipe for accurately controlling the temperature of the diffuser plate during CVD processing to prevent unwanted tungsten (or other material) deposition on the diffuser plate. The apparatus is also useful as an RF plasma cleaning device in which the diffuser plate acts as an RF electrode, the heat pipe tube acts as an RF input lead, and the apparatus further includes a connector to an RF power source. Additionally, in combination, the heat pipe-cooled gas diffuser plate and RF electrode may be used advantageously in plasma enhanced chemical vapor deposition (PECVD).
