    Abstract: An aircraft freestream data system can include a first ultrasonic air data system (UADS) (101) configured to sense local acoustic properties at a first location on an aircraft, a first local air data module (103) operatively connected to the first UADS and configured to determine first local air data of the first location and to output first local air data, and a freestream data module (105) operatively connected to the first local air data module. The freestream data module can be configured to receive the first local air data from the local air data module, determine one or more freestream air data parameters based on at least the first local air data, and output the one or more freestream air data parameters to one or more aircraft consuming systems.

    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).

    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 translation: 大气数据探头（10）包括探头主体（18）和布置在探头主体（18）中的大气数据传感端口（20）。 探针主体（18）包括筒状区域，从筒状区域向前延伸的锥形头部区域以及锥形头部区域的最前端处的尖端。 空气数据感测端口（20）设置在探针主体（18）中的尖端后方的端口位置处。 探头体（18）具有产生湍流的几何形状，该湍流产生几何形状起始于尖端，产生从尖端延伸到端口位置的湍流的气流边界层。
