EXTENDABLE DEFLECTOR FOR DISCHARGING STRUCTURE-DAMAGING FLUIDS
First Claim
1. A deflector for an aircraft, comprising:
- a discharge pipe for leading a fluid to be drained from the aircraft by way of an outlet end to the environment of the aircraft,an actuator, coupled to the discharge pipe for swinging out, when required, the discharge pipe to at least one activation position,wherein in the at least one activation position the outlet end is arranged so as to be spaced apart from the exterior skin of the aircraft, and the deflector guides the fluid to be drained so that it exits outside a flow boundary layer that is present on the exterior skin,wherein the actuator comprises an axially slidably supported piston that is designed to be moved by the fluid to be discharged, so as to extend the discharge pipe.

Abstract
The invention relates to a deflector for an aircraft, comprising a discharge pipe for leading a fluid to be drained from the aircraft by way of an outlet end to the environment of the aircraft; an actuator, coupled to the discharge pipe, for swinging out, when required, the discharge pipe to at least one activation position, wherein in the activation position the outlet end is arranged so as to be spaced apart from the exterior skin of the aircraft, and the deflector guides the fluid to be drained so that it exits outside a flow boundary layer that is present on the exterior skin. The deflector according to the invention is activated when required and is able to discharge structure-damaging fluids to the environment in such a way that the exterior structure of the aircraft does not become wet, and at the same time the deflector according to the invention, normally accommodated within the contour of the aircraft, does not result in any additional aerodynamic resistance.

15. A method for leading fluids out from the interior of an aircraft, the method comprising the steps of:
-
opening a cover on the exterior structure of the aircraft; extending a deflector by means of an axially slidably supported piston that is designed to be moved by the fluid to be discharged, so as to extend the discharge pipe; holding the position of the deflector; and draining the fluid without wetting the exterior structure of the aircraft. - View Dependent Claims (16)

18. An aircraft comprising at least one deflector, the deflector comprising:
-
a discharge pipe for leading a fluid to be drained from the aircraft by way of an outlet end to the environment of the aircraft, an actuator, coupled to the discharge pipe for swinging out, when required, the discharge pipe to at least one activation position, wherein in the at least one activation position the outlet end is arranged so as to be spaced apart from the exterior skin of the aircraft, and the deflector guides the fluid to be drained so that it exits outside a flow boundary layer that is present on the exterior skin, wherein the actuator comprises an axially slidably supported piston that is designed to be moved by the fluid to be discharged, so as to extend the discharge pipe.
