Problems solved by technology

Unfortunately, with current fabrication techniques, the probe body gradually develops a gap around the heat source, resulting in reduced mechanical strength as well as hot spots within the heating cable and cold spots on the outer surface of the probe

Abstract

The present invention relates to forming an atmospheric data probe from a porous cover and brazing material. Provides the probe section of the Atmospheric Data Probe. The probe portion includes: an inner skeleton structure having an outer surface; a heating cable disposed along the outer surface of the inner skeleton structure; a porous shield surrounding the inner skeleton structure and the heating cable; and a brazing filler material substantially filling the heating cable with the inner skeleton The gaps between the skeletal structures and substantially fill the gaps in the porous metal cover.

Description

Background technique [0001] Conventionally, air data probes are made by brazing components together to assemble a probe having a given aerodynamic shape. These atmospheric data probes include mechanisms to generate heat to de-ice and maintain ice-free conditions when operating in adverse weather conditions. Anti-icing and de-icing requirements are the subject of numerous aerospace standards and recommended aerospace practices. In 2014, the Department of Transportation and the Federal Aviation Administration issued new regulations to improve probe safety by addressing supercooled large droplet icing conditions, mixed phase and ice crystal icing conditions. As a result of these new regulations, the challenge of meeting anti-icing and de-icing requirements for atmospheric data probes has become much more demanding. [0002] One way to meet these new requirements is to place the heating source (eg, heating cable) closer to the outer surface of the probe portion of the air data p...
