Latest Patents

Kumasaka holds a patent for a jet engine noise suppressor. This invention features a compressor bleed air passageway that includes a duct with an upstream section terminating in a baffle. The downstream duct section surrounds the baffle and allows bleed air to flow through openings in the baffle wall. This design effectively reduces the velocity of the bleed air stream at the duct discharge port to a value equal to or less than Mach 1.0. The baffle has minimal impact on low-velocity, low-pressure air streams, and the downstream duct section may be perforated to form sound-absorbing chambers.
