Abstract: Noise produced by the blades of a wind turbine electric generator is reduced by creating randomly varied serrations on the trailing edge of the blade, thereby creating vortices of varying size, energy, and distance from the trailing edge. This configuration creates vortices that tend to cancel one another while avoiding the creation of adjacent, mutually reinforcing vortices.

Abstract: Muzzleloader systems include a pre-packaged propellant charge and primer for providing efficient loading and unloading of the muzzleloader. The breech end accepts the propellant and means are provided to prevent breech loading of the projectile. A propellant cartridge conforms to a constriction portion to minimize ullage. A projectile is inserted in the muzzle end seats on the constriction portion. The propellant cartridge may be received in a removable breech plug. The constriction portion may be part of the breech plug or a separate component secured in the barrel by way of the breech plug.

Projectiles have sliding components that have an axial elongate position and an axial shortened position and may be loaded with a ramrod having an engagement portion for each of the two pieces whereby the projectile doesn't prematurely collapse.

Abstract: A system for firing shell-cased projectiles including multiple barrels and a breech assembly, which includes multiple detonators each aligned to a corresponding one of the barrels. Each detonator may include a plunger coupled to a firing pin, and a solenoid for driving the plunger and firing pin toward the corresponding barrel upon firing, and an actuator-driven mechanical safety device including a slide plate switchable between first and second lateral positions. The slide plate may include multiple entrapment pins, each corresponding to one of the detonators. When the slide plate is in the first lateral position, each of the entrapment pins are positioned so as to obstruct movement of the plunger in the corresponding detonator, thereby rendering the corresponding detonator inoperable to fire even if the corresponding solenoid is actuated. On the other hand, when the slide plate is in the second lateral position, each of the detonators is operable to fire when the corresponding solenoid is actuated.
