Patent number: 4932612Abstract: A method and apparatus for reducing the skin friction on objects in relative motion to a field of fluid. The areas of relative low speed motion are fixed to align with a series of ridges on the surface of the object. The areas of low speed motion aligned with the ridges are removed by suction from the turbulent boundary layer which results in a reduction of drag on the object. An alternative embodiment injects fluid into areas of relative high speed between the ridges to reduce the shear and the drag caused by it. Selective suction and injection are combined in one apparatus in a second alternative embodiment. A fourth embodiment injects a polymeric solution to reduce drag. A fifth embodiment heats the fluid in specified areas to reduce drag. A sixth embodiment uses a compliant material in specified areas of the surface in contact with flowing fluid to reduce drag.Type: GrantFiled: October 26, 1987Date of Patent: June 12, 1990Inventors: Ron F.

Patent number: 4697769Abstract: The lift generated by delta wings is due primarily to large vortices associated with the flow separation near the leading edge. The invention includes a perturbation device to control the separation shedding of those vortices and manipulate their frequency and pairing. This results in different growth rates of the vortices downstream of the device and thus the lift produced by the large bound vortices may be controlled. If the invention is applied to both leading edges, the total lift of the wing will be altered; if the perturbation is preferentially applied on only one side of the wing, the moment around the roll axis of the aircraft is controlled. A first embodiment uses a piston coupled to a cavity and slot to produce the desired perturbation. Alternative embodiments are described which achieve the results without moving parts.Type: GrantFiled: April 23, 1984Date of Patent: October 6, 1987Assignee: Flow Industries, Inc.Inventors: Ron F. Blackwelder, Mohamed Gad-el-Hak, Randy A. Srnsky

Patent number: 4671064Abstract: A heat exchanger having annular construction for a constant operation at high temperatures and pressures. A series of heating walls at high temperature surround the fluid to which heat is desired to be transferred in annular spaces. Counterbalancing pressures in areas filled with high pressure fluid and insulating gases allow use of thinwall construction for the heating walls to reduce cost and increase heat transfer. Spacers that are placed under compression are provided to maintain dimensional stability and transmit forces. Embodiments describing the use of the device as a heater or cooler and operation in either direction are illustrated. A second embodiment illustrates a heater with single sided heating of the fluid desired to be heated.Type: GrantFiled: November 30, 1984Date of Patent: June 9, 1987Assignee: Stirling Engine AssociatesInventors: Maurice A.

Patent number: 4665944Abstract: This invention relates to a high pressure valve of the dump type. The valve body contains a slideable, hollow spool with ports connecting its interior and exterior. When the valve is in the on position, all ports are located in the pressurized portion of the valve body, and fluid flows to an outlet connected to the hollow spool. In the off position, at least one port is outside the pressurized area of the valve body, thereby relieving fluid pressure. The ports slide through a seal of self-pressurizing construction. The valve may also be used as a high pressure swivel, or combination valve swivel, by rotating the spool, if the spool is supported by bearings.Type: GrantFiled: February 14, 1985Date of Patent: May 19, 1987Assignee: Flow Industries, Inc.Inventors: Gerald F.
