    摘要: An electrothermal ice protection system (IPS) installed on an aircraft includes a sensor, a parting strip assembly, and a controller. The sensor monitors a direction of a local incident airflow that is imparted on the sensor. The parting strip assembly is coupled to the critical surface and includes a plurality of heating sections. The controller is in signal communication with the sensor and the parting strip assembly. The controller determines a direction of surface airflow incident on a critical surface of the aircraft based on the local incident airflow and selectively concentrates power to at least one targeted heating section among the plurality of heating sections with respect to non-targeted heating sections among the plurality of heating sections based on the direction of the surface airflow.

    摘要: A heating element includes a first bus bar disposed to receive current from a power source, and a second bus bar non-adjacent to the first bus bar. The heating element further includes a polymer ink section extending between the first and second bus bars, and the section includes a plurality of PTC polymer inks each different from one another. The second bus bar is electrically connected to the first bus bar via the polymer ink section.

    摘要: Disclosed is an attachment between a bus bar and a nano-carbon heater used for de-icing and/or anti-icing in an aircraft or other vehicle. The attachment between the bus bar and the heater is created through a coupling agent, a pre-preg glass fabric, and a conductive adhesive. This attachment allows for electrical connections to be made to the heater via the bus bar, and the attachment is strong enough to withstand stress from thermal cycles.
