Embodiment Construction

[0032] The different advantageous embodiments recognize and take into account a number of different considerations. As used herein in reference to items, "plurality" means one or more than one item. For example, "a plurality of different considerations" means one or more than one different considerations.

[0033] The different advantageous embodiments recognize and take into account that in some applications where coaxial tubing is desired, it is desirable to provide an electrostatic connection between the inner and outer tubes of the coaxial tubing. For example, it is desirable to provide electrostatic bonding between the inner and outer tubes of coaxial ducts in aircraft to support safe operation of the aircraft in various electromagnetic operating conditions and environments.

[0034] The different advantageous embodiments recognize and take into account that an electrostatic connection between tubes of coaxial tubes can be made using bonded jumpers / jumpers. For example,...

Abstract

A method and apparatus for electrostatically bonding coaxial tubing. An outer tube (602) comprises an electrically conductive material and has an inner surface. An inner tube (604) comprises material and has an outer surface. The inner tube (604) and the outer tube (602) are positioned to define a channel (606). A bridging structure (608) comprising an electrically conductive material is positioned such that the bridging structure forms mechanical contact and an electrostatic connection between electrically conductive material on the tubes. The bridging structure is in mechanical contact with the inner surface of the outer tube at a first plurality of points and in mechanical contact with the outer surface of the inner tube at a second plurality of points.

Description

technical field [0001] The present disclosure relates generally to coaxial duct systems used in vehicles such as aircraft. More specifically, the present disclosure relates to forming an electrostatic connection between outer and inner pipes of a coaxial piping system without creating inconsistencies in the pipe surface. Background technique [0002] Piping systems are used to carry various fluids through aircraft and other vehicles. For example, piping may be used in aircraft to carry hydraulic fluid used by hydraulic systems on the aircraft. As another example, piping is used in aircraft to carry fuel between fuel tanks and aircraft engines. Piping systems may be used to carry other fluids on aircraft and other vehicles. [0003] It is desired that ductwork used on an aircraft may have a variety of characteristics to enhance aircraft performance and safety. For example, utilizing lighter ductwork in aircraft can improve aircraft performance by increasing fuel efficienc...
