Abstract: A noise suppression system for an electric generator having a housing including an internal combustion engine and air-cooled alternator. A fan draws ambient cooling air into the housing for cooling the alternator. The system may include an acoustically designed noise suppression shroud forming a cavity which contains a plurality of parallel flow baffles. The baffles define air flow passages there-between which receive cooling air heated by the alternator. In one system, the baffles are configured and arranged to block a straight line of sight between the entrance and exit of each passage. The baffles may each further include sound deadening materials on one or both sides in some configurations. Heated cooling air flows into the shroud and through the passages before being discharged from the housing. The shroud is operable to suppress noise produced by the cooling air discharge flow. Various shroud configurations may include additional sound proofing features.

Abstract: Some embodiments relate to a power generation system that includes a first side member and a second side member that is parallel to the first side member. At least one cross member extends between the first side member and the second side member. In some embodiments, the power generation system includes a first cross member and a second cross member. The first cross member includes a pair of flat mating surfaces that are parallel to the first cross member. The first cross member further includes a pair of angled mating surfaces that are at an angle relative to the first cross member. The power generation system further includes a power source that includes an alternator and an engine that drives the alternator to generate power. At least one of the engine and the alternator is mounted to the pair of flat mating surfaces or pair of angled mating surfaces.

Abstract: The towable power generation system includes an internal combustion engine and an alternator driven by the internal combustion engine to generate electrical power. The towable power generation system further includes a trailer configured to be attached to a vehicle that is adapted to tow the trailer. A base (e.g., a skid) is attached to the trailer such that the internal combustion engine and the alternator are mounted on the base. The trailer includes one or more axles, wheels, a frame and a tongue for attaching the trailer to a towing vehicle. An enclosure houses the internal combustion engine and the alternator. The enclosure is detachably connected to the base using fasteners such that when the fasteners are removed only the enclosure is removed from the base and every other part of the towable generator system remains in place.
