Abstract:
An electronic system of a device includes first (102) and second circuit boards (104) and a flexible connector configured to electrically connect the first and second circuit boards. The flexible connector includes a serpentine portion (28) that includes first, second and third legs (30, 32, 34). The first leg (30) that extends in a first direction, the second leg (32) extends in a second direction opposite of the first direction, and the third leg (34) extends in the first direction. The first, second and third legs (30, 32, 34) are configured in a common plane when the device is in an operational state.

A total air temperature probe (10) includes a housing (12) having inner surfaces defining an airflow passage, a first section of the airflow passage of the housing (12) having an airflow inlet scoop with a first cross-sectional area and an inertial separation bend downstream of the airflow inlet scoop, wherein the airflow passage is configured to be substantially straight; and a second section of the airflow passage of the housing having a main exit channel and an elongated outlet with a second cross-sectional area, wherein the airflow passage is contoured to direct particle deflections to the elongated outlet, wherein the second section is downstream from the first section, and wherein the first cross-sectional area is greater than the second cross-sectional area.
Abstract:
A pitot tube includes a substantially cylindrical body portion (12) having an interior defining a flow passage and a tip portion (14) extending along a pitot tube axis from the body portion. The tip portion includes a disk (250), a tip cover (254) and a high thermal conductive insert (252) disposed between the disk and the tip cover and in thermal contact with both.
Abstract:
A system (100) including an aircraft interface device (104) configured to communicate with an aircraft avionics system (102) and a tablet interface module (106) configured to communicate with the aircraft interface device (104) and with one or more tablets (108). The aircraft avionics system (102) includes a plurality of sensors for an aircraft and the tablet interface module (106) provides the one or more tablets (108) with information received from the aircraft interface device (104).
Abstract:
A total air temperature sensor includes a probe head (102), a strut (104), and a turbulence inducing surface (116). The probe head has an airflow inlet (106) and an airflow outlet (108). The strut defines a leading edge (110) and an opposed trailing edge (112) extending along a longitudinal axis (A), and connects between the probe head and an opposed probe mount (114). The turbulence inducing surface is defined in the strut aft the leading edge. The turbulence inducing surface is configured to trip a fluid boundary layer passing over the strut to transition from laminar to turbulent for moving flow separation toward the trailing edge to reduce acoustic noise emission from the total air temperature sensor.
