Appl. No.:

10/862068

Inventors:

John A. Severson - Eagan MN, US
Kenneth J. Freeman - Eagan MN, US
Dennis J. Cronin - Shakopee MN, US

Assignee:

Rosemount Aerospace, Inc. - Burnsville MN

International Classification:

G01K 1/00

US Classification:

702130

Abstract:

A temperature sensor is provided with at least two thermometers or temperature sensing elements that have different recovery factors, and which are in the same airflow. The recovery factors for the respective thermometers are determined for the sensor and stored in a memory of a processor. The temperature measured by each of the thermometers is provided to the processor, and the processor establishes ratios using the recovery factors and measured temperatures to determine total temperature and static temperature of the airflow in which the thermometers are placed.

Appl. No.:

7/590142

Inventors:

Kenneth J. Freeman - Eagan MN

Assignee:

Rosemount Inc. - Eden Prairie MN

International Classification:

H05B 102

US Classification:

219497

Abstract:

An ice detector circuit controls heating of a probe detecting ice. The circuit generates an icing output as a function of a temperature output generated by the probe. A control circuit cyclically controls a start time of the heating. A time measurement circuit measures a warm-up time to a first temperature threshold below the melting temperature, and measuring a melting time to a second temperature above the melting temperature. A comparator compares the melting time to a stored comparison parameter adjusted by the warm-up time and provides the icing output.

Kenneth J. Freeman - Eagan MN

International Classification:

H01R 909

US Classification:

439 76

Abstract:

An air data module connector and filter that provides a shielded housing 12 for supporting a standard air data signal carrying cable connector 22 on an exterior wall thereof, and having an access opening that has a cover plate 34 on an opposite wall from the mounting wall for the connector. The cover plate 34 has a plurality of tubular filters 36 installed therein with pins 40 extending into the housing toward the cable connector. A flexible circuit board 44 has opposite ends which fit on the pins of the connector 23, and the pins 40 of the filters 36 extending through the cover plate, respectively, so that the flexible circuit board 44 can be installed on the cable connector 23 and on the pins 40 for the filters on the cover plate 34 prior to assembly of the cable connector and the cover plate 34 in the housing 12.

Alexander N. Reid - St. Louis Park MN, US
Timothy DeAngelo - Edina MN, US

International Classification:

B64D 43/02
B64D 15/12

Abstract:

An angle of attack sensor includes a housing, a heated chassis positioned at least partially within the housing and defining a pocket, a mounting plate positioned adjacent the heated chassis and having a circular opening, an external surface facing away from the housing, and an internal surface facing toward the housing, and a vane assembly extending through the circular opening of the mounting plate. The vane assembly includes a vane extending from a root to a tip and a vane base connected to the root of the vane and positioned within the pocket of the heated chassis such that the vane base is offset inwardly from the external surface toward the housing.

G01F 1/684

Abstract:

An angle of attack sensor includes a housing having an open first end and a closed second end, a heated chassis positioned within the open first end of the housing, a mounting plate positioned on the heated chassis adjacent the open first end of the housing such that an internal chamber is formed between the heated chassis and the mounting plate, a transducer compartment between the heated chassis and the closed second end of the housing, and a water management system located adjacent the internal chamber and the transducer compartment. The water management system includes an annular chamber positioned in the internal chamber, a first tube at a first end of the annular chamber, and a second tube at a second end of the annular chamber. The first tube has a hole such that the first tube is in fluid communication with the annular chamber and the internal chamber, and the second tube is in fluid communication with the annular chamber and the transducer compartment.

Kenneth Freeman - Eagan MN, US

International Classification:

G01P 13/02
B64D 43/02
B64D 15/12

Abstract:

An angle of attack sensor includes a vane that is freely rotatable to align with a direction of an oncoming airflow over the vane. The airfoil includes a root proximate a vane hub that connects to a rotatable shaft, a tip opposite the root, a leading edge, a trailing edge opposite the leading edge, a first lateral face, a second lateral face, and a heating element disposed within the airfoil between the first and second lateral faces proximate the leading edge. The first lateral face extends from the leading edge to the trailing edge. The second lateral face is opposite the first lateral face and extends from the leading edge to the trailing edge. The first and second lateral faces are symmetric about a chord of the airfoil and each have an outer surface profile that is nonlinear and geometrically convex from the leading edge to the trailing edge.
