System And Method For Control Of Aeroelasticity Effects

View page
US Patent:
8155794, Apr 10, 2012
Filed:
May 8, 2008
Appl. No.:
12/117010
Inventors:
Arun S. Mangalam - Williamsburg VA,
Siva M. Mangalam - Williamsburg VA,
Assignee:
Tao of Systems Integration, Inc. - Hampton VA
International Classification:
G06F 19/00
US Classification:
700282, 701 3, 702 45, 73147
Abstract:
A system is provided for control of a structure immersed in a fluid flow regime. The system comprises a plurality of flow sensors disposed on a surface of the structure, the flow sensors including at least one flow bifurcation point sensor. The system further comprises at least one structural sensor attached to the structure for measurement of a structural parameter. A data processor in communication with the flow sensors and the at least one structural sensor is configured for processing the data signals and for generating and transmitting one or more actuator command signals to effect a desired flow and structural state for the structure. The system also comprises at least one actuator in communication with the data processor. Each of the at least one actuator is configured for effecting, in response to an actuator command signal, one of the set consisting of a structural deformation in at least a portion of the structure, a change in configuration of a control surface of the structure, and an operational change in a flow control device embedded in the structure.

US Patent:
8306800, Nov 6, 2012
Filed:
Jul 8, 2009
Appl. No.:
12/499324
Inventors:
Siva M. Mangalam - Williamsburg VA,
Arun Mangalam - Williamsburg VA,
Assignee:
Tao of Systems Integration, Inc. - Hampton VA
International Classification:
G06G 7/48
US Classification:
703 9
Abstract:
A method is provided for calculating flow performance characteristics of a body immersed in a fluid under a set of fluid flow conditions. The method comprises providing a geometrical description of a surface of the body and determining the set of fluid flow conditions. The set of fluid flow conditions includes a combination selected from the combination set consisting of angle of attack and leading edge stagnation point location, angle of attack and flow separation point location, and leading edge stagnation point location and flow separation point location. The method further comprises calculating a velocity flow field for the body using a critical point potential flow methodology and calculating flow performance characteristics.

US Patent:
2007025, Oct 25, 2007
Filed:
Apr 20, 2007
Appl. No.:
11/737831
Inventors:
Arun S. Mangalam - Williamsburg VA,
Siva M. Mangalam - Williamsburg VA,
International Classification:
G06F 19/00
G01F 1/00
US Classification:
702 47, 702 1, 702 45, 702 50, 73861, 7320411, 7320414, 7320417
Abstract:
A temperature compensating fluid flow sensing system is provided that comprises a resistance-based sensor element that is included in a constant voltage anemometer circuit configured to establish and maintain a command voltage across the first sensor element and to provide a CVA output voltage corresponding to the resistance change in the first sensor element due to heat transfer between the first sensor element and the fluid. A controller is configured to establish the command voltage based on a desired overheat across the sensor and an actual overheat across the first sensor element. A PDR module is configured to determine at least one fluid flow parameter and an actual overheat value based at least in part on the CVA output voltage and to transmit to the controller the actual overheat for use by the controller in updating the command voltage.

US Patent:
2011024, Oct 6, 2011
Filed:
Mar 31, 2011
Appl. No.:
13/076901
Inventors:
Arun Mangalam - Williamsburg VA,
International Classification:
G01L 5/00
G06F 19/00
US Classification:
702 43, 702 41
Abstract:
A method is provided for determining an aerodynamic coefficient for a body immersed in a fluid under a set of fluid flow conditions. The method comprises obtaining surface flow parameter data for a plurality of locations on the body. These locations include body surface points straddling an area of the body surface where a leading edge stagnation point (LESP) is expected to be located. The method further comprises determining the LESP location and an angle of attack of the body with respect to freestream conditions of the fluid using the flow parameter data. The method also comprises determining the aerodynamic coefficient from the LESP location and the angle of attack using an aerodynamic model.

System And Method For Determining Fluid Speed

US Patent:
2013011, May 9, 2013
Filed:
Nov 2, 2012
Appl. No.:
13/667740
Inventors:
Tao of Systems Integration, Inc. - Hampton VA,
Arun Mangalam - Williamsburg VA,
Assignee:
Tao of Systems Integration, Inc. - Hampton VA
International Classification:
G01F 1/32
G01F 1/00
US Classification:
7386122, 73861
Abstract:
A flow speed sensor arrangement is provided for measuring a flow speed of a fluid stream relative to an object. The arrangement comprises a first obstructive body having a first forward facing surface and two lateral edges and a second obstructive body having a second forward facing surface. The second obstructive body is positioned in tandem relative to the first obstructive body so that the first and second forward facing surfaces face the same direction and so that when the first forward facing surface is presented to an incoming fluid stream, the first obstructive body is between the incoming fluid flow and the second obstructive body. A sensor array is disposed on the second forward facing surface. The first and second obstructive bodies are attachable to the object so that the first forward face is presented to an incoming fluid stream when the object is immersed in the fluid stream.
