Abstract

Sonda de medición de presión de aire con calefacción de eliminación de la cubierta de hielo. Una sonda de medición de presión de aire para aeronave y propulsiones de vuelo aeróbicas presenta una calefacción de eliminación de cubierta de hielo (7) y una tubería de presión (5) que desemboca frente a una masa de aire a una circulación de aire que tiene que ser medida. Las ondas de medición de este tipo sirven, por ejemplo, para el cálculo de la presión estática de aire en la entrada de aire de motores a reacción. Estas están dotadas de una calefacción eléctrica para evitar la cubierta de hielo, para recibir valores correctos de aire también en caso de uso bajo condiciones de formación de la cubierta de hielo. La calefacción (7) de eliminación de la cubierta de hielo está dotada en un soporte de calefacción (8) para un consumo mínimo de corriente con la prestación fiable de la eliminación de la cubierta de hielo, dentro del cual discurre un segmento de la tubería de presión (5), que está envuelto concéntricamente por al menos un elemento de calefacción (9) de PTC en forma de anillo, en donde el soporte de calefacción (8) presenta una brida (11) configurada coaxial entre el elemento (9) de calefacción y la abertura (4) de la tubería de presión (5), en cuya superficie frontal (12) en forma de anillo apoya plano el elemento de calefacción (9) en enlace de conducción de calor.Air pressure measurement probe with ice cover elimination heating. An air pressure measurement probe for aircraft and aerobic flight propulsions has an ice cover elimination heating (7) and a pressure pipe (5) that flows in front of a mass of air into an air circulation that has To be measured. Measuring waves of this type are used, for example, to calculate the static air pressure at the air inlet of jet engines. These are equipped with an electric heating to avoid the ice cover, to receive correct air values also in case of use under conditions of ice cover formation. The ice cover elimination heating (7) is provided in a heating support (8) for a minimum current consumption with the reliable provision of the ice cover elimination, within which a segment of the pipe runs pressure (5), which is concentrically wrapped by at least one ring-shaped heating element (9) of PTC, wherein the heating support (8) has a flange (11) configured coaxially between the element (9) of heating and the opening (4) of the pressure pipe (5), whose heating surface (12) in the form of a ring supports the heating element (9) in a heat conduction link.
