Abstract:
A wall for a heated faceplate includes a base and tines protruding from the base and spaced from each another. The tines are configured to accumulate ice in a manner which promotes shedding of small ice formations to prevent large accumulations of ice father aft on the faceplate.
Abstract:
An air data probe (10) includes a probe body (18) and an air data sensing port (20) disposed in the probe body (18). The probe body (18) includes a barrel region, a tapered head region extending forward from the barrel region, and a tip at a forward-most end of the tapered head region. The air data sensing port (20) is disposed in the probe body (18) at a port location aft of the tip. The probe body (18) has a turbulence-producing geometry originating at the tip that produces a turbulent boundary layer of airflow that extends from the tip to the port location.
Abstract:
An air data probe (16) includes a housing and a probe head (18) with a body (28), total pressure (44) and alpha (46A, 46B) chambers, total pressure (34) and alpha ports, and alpha drain ports (40A, 40B). The total pressure chamber (44) extends through a radial center of the body (28). The alpha chambers (46A, 46B) are disposed radially outward from the total pressure chamber (44). The total pressure port (34) is disposed in a distal end of the body (28) is collinear with a centerline axis of the body (28). The total pressure chamber (44) is in fluid communication with the total pressure port (34) and with the housing. The alpha ports (36A, 36B) are disposed downstream of the total pressure port (34) and upstream of the housing. The alpha chambers (46A, 46B) are in fluid communication with the alpha ports (36A, 36B). The alpha drain ports (40A, 40B) are disposed downstream from the alpha port (36A, 36B) and upstream from the housing. The alpha drain ports (40A, 40B) fluidly communicate with the alpha chamber (46A, 46B).

A wall (20) for a heated faceplate (10) includes a base (30A; 30D) and tines (32A; 32D) protruding from the base (30A; 30D) and spaced from each another. The tines (32A; 32D) are configured to accumulate ice in a manner which promotes shedding of small ice formations to prevent large accumulations of ice father aft on the faceplate (10).
Abstract:
A device is disclosed for measuring total pressure of a fluid flow comprises a tubular member having an inlet chamber with an inlet opening at a first end of the tubular member. The tubular member also comprises an outlet chamber having an outlet opening at a second end of the tubular member. The inlet opening has a diameter transverse to the longitudinal axis and the outlet opening has a second diameter transverse to the longitudinal axis. The ratio of the first diameter to the second diameter is from 3:1 to 10:1. The tubular member also includes a transitional chamber between the inlet chamber and the outlet chamber. Total pressure can be measured in the inlet chamber.
