Abstract:
An example apparatus includes a power-factor correction (PFC) circuit 200 coupleable to a primary load 202 that exhibits a change in resistance with a change in applied voltage, with the respective voltage being a primary-load voltage, and current through the primary load being a primary-load current. The PFC circuit is configured to provide an auxiliary load and control current therethrough, with the respective current being an auxiliary-load current. In this regard, the PFC circuit is configured to control the auxiliary-load current such that the sum of the primary-load current and auxiliary-load current is a substantially-constant proportion of the primary-load voltage, the respective sum being a sum current.
Abstract:
An air data probe (10;26;42) includes an air data probe body (12;28;44) and an additively manufactured heater (100-900) on the air data probe body.
Abstract:
A pitot tube (10) includes a substantially cylindrical body portion (12) and a tip portion (14) extending along a pitot tube axis (16) from the body portion (12). The tip portion (14) includes an inlet opening (20) and a radially tapering outer surface (26) extending from the body portion (12) toward the inlet opening (20). Another pitot tube (10) includes a substantially cylindrical body portion (12) and a tip portion (14) extending along a pitot tube axis (16) from the body portion. The tip portion (14) includes an inlet opening (20). One or more electrical coils (34) including one or more coil wraps (46) are located at an interior (30) of the pitot tube (10). One or more bulkeads (58) are located between a forwardmost coil wrap (46A) and a drainage feature (58) to limit travel of particles ingested into the interior (30).
