Abstract
Abstract The invention relates to a rigid wing flying craft having at least one airfoil and at least one driving unit and a cabin for receiving loads. At least one air channel piercing the airfoil is provided in the surface center of the airfoil and at least two steering fins for steering the flight movements are pivotably supported in the air channel. The driving unit and the steering fins are arranged at least partially within said air channel and pivotably supported within the same around an axis of rotation which extends essentially vertically in relation to the axis of the driving unit.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
200 words
A rigid wing flying craft comprising at least one airfoil, at least one driving unit and a cabin for receiving loads, wherein at least one air channel piercing the airfoil is provided generally in the surface center of the airfoil for the airstream generated by the driving unit, at least two steering fins for steering flight movements are pivotally supported in the air channel near the mouth thereof, a radial guide vane system with guide vanes is provided coaxial with the axis of said driving unit for generating a counter torque, said steering fins and said guide vanes are pivotally supported around axes of rotation extending essentially perpendicular to the axis of said driving unit, said driving unit is pivotally supported to at least one inclined position in relation to said airfoil, and a common shell is provided surrounding said driving unit, guide vane system and steering fins whereby said steering fins are located in the airstream at any position of said driving unit, wherein said guide vanes are pivotally supported on said driving unit, on the one hand, and on said common shell, on the other hand, while said steering fins are pivotally supported on said driving unit only.
Claim 2
Dependent Claim
200 words
A rigid wing flying craft comprising at least one airfoil, at least one driving unit and a cabin for receiving loads, wherein at least one air channel piercing the airfoil is provided generally in the surface center of the airfoil for the airstream generated by the driving unit, at least two steering fins for steering flight movements are pivotally supported in the air channel near the mouth thereof, a radial guide vane system with guide vanes is provided coaxial with the axis of said driving unit for generating a counter torque, said steering fins and said guide vanes are pivotally supported around axes of rotation extending essentially perpendicular to the axis of said driving unit, said driving unit is pivotally supported to at least one inclined position in relation to said airfoil, and a common shell is provided surrounding said driving unit, guide vane system and steering fins whereby said steering fins are located in the airstream at any position of said driving unit, wherein said guide vanes are pivotally supported on said driving unit, on the one hand, and on said common shell, on the other hand, while said steering fins are pivotally supported on said driving unit only.
Claim 3
Dependent Claim
34 words
A flying craft according to claim 1, wherein the guide vane system for the generation of the counter torque is functionally coupled to a tail unit supported on the tail side of the airfoil.
Claim 4
Dependent Claim
31 words
A flying craft according to claim 1, wherein the axis of the driving unit and the axis of the air passage are arranged in the central longitudinal axis of the airfoil.
Claim 5
Dependent Claim
12 words
A flying craft according to claim 1, wherein the airfoil is delta-shaped.
