Richard A Oman, Kenneth M Foreman: Variable stator, diffuser augmented wind turbine electrical generation system. Grumman Aerospace Corporation, Richard G Geib, Mellor A Gill, February 21, 1978: US04075500 (102 worldwide citation)

A wind powered electrical generating system having a suitable shaped aerodynamic duct or shroud within which a wind turbine having a fixed pitch blade is mounted, as by means of a stator means at the inlet of the duct or shroud with the stator means including mechanism for varying their effective an ...

Kenneth M Foreman, Barry L Gilbert: Diffuser for augmenting a wind turbine. The United States of America represented by the United States Department of Energy, Jeannette M Walder, Walter L Rees, Michael F Esposito, November 13, 1984: US04482290 (30 worldwide citation)

A diffuser for augmenting a wind turbine having means for energizing the boundary layer at several locations along the diffuser walls is improved by the addition of a short collar extending radially outward from the outlet of the diffuser.

Kenneth M Foreman, Richard C Jenkins: S-shaped jet engine inlet diffuser. Grumman Aerospace Corporation, Pollock VandeSande & Priddy, February 5, 1991: US04989807 (13 worldwide citation)

A horizontal inlet section of a jet engine diffuser extends to a transitional curved section which, in turn, extends to a horizontal outlet section offset from the horizontal inlet section to shield observation of infrared and microwave signals from a downstream jet engine. A vane between the inlet ...

Kenneth M Foreman, Richard A Oman: Acoustic emission flow measurement system. Grumman Aerospace Corporation, Morgan Finnegan Pine Foley & Lee, May 25, 1976: US03958458 (12 worldwide citation)

Pseudo sound created by the interaction of fluid flowing over a discontinuity in a conduit is sensed by a transducer. The transducer signal is reduced to a frequency-amplitude distribution and the amplitude at the characteristic frequency is used to calculate fluid flow rate using a dipole model. Th ...

Kenneth M Foreman, Algirdas Maciulaitis: Hypersonic gasdynamic laser system. Grumman Corporation, Scully Scott Murphy & Presser, May 22, 1990: US04928286 (3 worldwide citation)

A visible, or near to mid infra-red, hypersonic gasdynamic laser system incorporated in a hypersonic vehicle which provides high enthalpy ram air for thermodynamic excitation of the laser gases. The hypersonic vehicle defines therein a laser cavity, and ram air directed therethrough supports gasdyna ...
