Latest Patents

Grotz's latest patents include groundbreaking inventions aimed at improving the Coanda effect flow in aircraft. One of his notable patents is a boundary layer scoop designed to enhance the Coanda effect flow in STOL (Short Takeoff and Landing) aircraft. This invention features turbojet or turbofan engines mounted above and forward of the wing, allowing engine exhaust gases to flow over the wing's upper surfaces. The design includes a downwardly curved extendible flap that produces a downwardly turned exhaust flow, generating a significant vertical thrust component. The boundary layer scoop effectively prevents premature separation of the exhaust flow from the wing or flap, ensuring optimal performance.

Another significant patent by Grotz is a method and apparatus for enhancing Coanda flow attachment over a wing. This invention involves directing jet exhaust flow toward regions where the exhaust flow separates from the wing and flap surfaces. By creating outward velocity components and vortices on the wing and flap surfaces, Grotz's method promotes flow attachment and improves overall aircraft efficiency.
