Publication number: 20240017840Abstract: An ice protection system for an aircraft includes an ice detector disposed in an external aircraft surface, a temperature sensor, and a controller. The ice detector includes an ice sensor. The controller includes an icing threshold module which receives a temperature measurement from the temperature sensor, receives an ice accretion signal from the ice sensor, compares the temperature measurement to an icing threshold temperature, and determines whether the temperature measurement is above the icing threshold temperature.

Patent number: 10625869Abstract: Apparatus and associated methods relate to determining, based on a spatial extent of ice accretion, whether an atmosphere contains super-cooled water droplets that equal and/or exceed a predetermined size. A convex-shaped housing is mounted to an aircraft and exposed to an airstream. The convex-shaped housing has a testing region that is monitored for ice accretion by an ice detector. A boundary locator determines a specific location to be tested within the testing region. The determined specific location corresponds to a calculated boundary that separates an ice-accretion region from an ice-free region if the atmosphere contains super-cooled water droplets up to the predetermined size. If the ice detector detects ice accretion at the determined specific location, an alert is generated. The alert can advantageously inform a pilot of an atmosphere containing super-cooled water droplets that equal or exceed the predetermined size.Type: GrantFiled: June 28, 2016Date of Patent: April 21, 2020Assignee: Rosemount Aerospace Inc.Inventors: Vincent R.

Patent number: 10611488Abstract: Apparatus and associated methods relate to projecting a light beam onto an interior surface of an aircraft window so as to indicate a testing location to test for ice accretion. The testing location is determined, by a boundary locator, based on aircraft flight conditions, aircraft exterior shape, and a predetermined size of super-cooled droplets, which could present a hazard to the aircraft. The determined test location corresponds to a calculated boundary that separates locations where super-cooled water droplets of the predetermined size cause ice-accretion from locations where such particles do not cause ice accretion, for such aircraft flight conditions. The light beam is then projected onto the interior surface of the aircraft window at the determined test location. The projected beam of light can indicate, to an observer and/or a detector, a location to monitor for ice accretion caused by super-cooled water droplets of the predetermined size.Type: GrantFiled: May 5, 2017Date of Patent: April 7, 2020Assignee: Rosemount Aerospace Inc.Inventors: Vincent R.

Patent number: 10435161Abstract: Apparatus and associated methods relate to differentiating ice accretion caused by different supercooled water droplets on an airfoil of an aircraft. A sensor having a sensing surface region is mounted at a mounting location of the airfoil such that the sensing surface region is flush with a surrounding adjacent surface of the airfoil. Water particles of sizes less than or equal to a predetermined threshold do not impinge the sensor surface region at the mounting location when the aircraft is in flight. A sensor driver provides an excitation signal to the sensor. A signal detector detects a sensor signal responsive to the provided excitation signal. The sensor signal is indicative of water particles exceeding the predetermined threshold impinging the sensing surface region. In some embodiments, the sensing surface region is mechanically coupled to a resonant cavity. In other embodiments, the sensor is a surface resistance sensor configured to sense surface resistance.Type: GrantFiled: May 2, 2018Date of Patent: October 8, 2019Assignee: Rosemount Aerospace Inc.Inventors: Vincent R.

Patent number: 10124900Abstract: Apparatus and associated methods relate to determining, based on a spatial extent of ice accretion, a maximum size of super-cooled droplets contained in an atmosphere and/or if an atmosphere contains super-cooled water droplets that equal and/or exceed a predetermined size. A testing region on an exterior surface of an aircraft is monitored for ice accretion by an ice detector. A boundary calculator determines a specific location to be tested within the testing region. The determined specific location corresponds to a calculated boundary that separates an ice-accretion region from an ice-free region if the atmosphere contains super-cooled water droplets of no larger than the predetermined size. If the ice detector detects ice accretion at the determined specific location, an alert is generated. The alert can advantageously inform a pilot of the aircraft that the atmosphere contains super-cooled water droplets that equal or exceed the predetermined size.Type: GrantFiled: June 28, 2016Date of Patent: November 13, 2018Assignee: Rosemount Aerospace Inc.Inventor: Vincent R.

Patent number: 10093426Abstract: Apparatus and associated devices relate to a system for measuring a maximum size of super-cooled water droplets in a cloud atmosphere. The system includes a housing having a convex exterior surface on a forward end and having stabilizers projecting from an aft end. The system includes a gimballed mounting mechanism configured to attach the housing to an aircraft while permitting the housing to freely pitch and yaw with respect to the aircraft. When an airstream engages the stabilizers, the housing aligns with a direction of the engaging airstream. The system includes a sequence of indices on a corresponding sequence of ice-accretion regions of the convex exterior surface, each of the sequence of indices visible in the absence of ice accretion. The forward-most ice-free one of the sequence of indices is indicative of a maximum size of super-cooled water droplets.Type: GrantFiled: October 24, 2016Date of Patent: October 9, 2018Assignee: Rosemount Aerospace Inc.Inventor: Vincent R.
