A vehicle fairing includes an electrical routing for conducting power and/or control signals between spaced-apart components of a vehicle structure. The vehicle fairing includes an outer surface configured to form part of an outer surface of a vehicle body. The electrical routing includes a printed circuit board having a substrate and a first conductive path for conduction of electrical current or signals provided on the substrate. The substrate is substantially rigid and forms at least a portion of the outer surface of the vehicle fairing.

A tip structure for an aircraft airfoil, such as a control surface (ailerons, flaps, elevators, rudders, etc) and/or a lifting surface (wings, HTP's, VTP's) is a unitary body and includes a tip shell and a metallic material on the outer surface of the tip shell suitable to withstand a lighting strike. The tip shell has been obtained by a single-stage injection molding process using a thermoplastic composite material having fibers dispersed therein, and the metallic material has been integrally formed with the tip shell.

Method and system to deliver anti-ice fluid to an ice prone surface using a pressurized tank pressurized with engine bleed air. The method and system further uses an eductor to evacuate anti-ice fluid such that the anti-ice fluid's unwanted leakage is eliminated or reduced. The method and system further measures a flow rate of anti-ice fluid using a positive displacement fluid meter.

A structure adapted to traverse a fluid environment exerting an ambient fluid pressure is provided. The structure includes an elongate body extending from a root to a wingtip and encapsulating at least one interior volume containing an interior fluid exerting an interior fluid pressure that is different from the ambient fluid pressure. A method of retrofitting a structure adapted to traverse a fluid environment exerting an ambient fluid pressure, the structure comprising an elongate body extending from a root to a wingtip and having at least one interior volume is also provided. The method includes sealing the elongate body to encapsulate the at least one interior volume containing an interior fluid; associating at least one valve with the at least one interior volume; and modifying interior fluid content via the at least one valve to produce an interior fluid pressure that is different from the ambient fluid pressure.
