Aircraft configuration
An aircraft ( 1 ), in particular a passenger or cargo aircraft, with a fuselage ( 2 ), has a tandem wing arrangement and has at least two aero engines ( 5, 6 ) disposed on the upper surface of the rear wing ( 4 ). In this way the disadvantages of the known solutions of the prior art are avoided and an improved aircraft configuration with improved aerodynamics, namely clearly reduced induced drag, is provided. Moreover, the invention creates an environmentally friendly aircraft design which conserves resources, increasing the acceptance of such aircraft among the population.
1. An aircraft comprising:
a tandem wing arrangement comprising a front wing and a rear wing, and at least two aero engines disposed on the upper face of the rear wing, wherein the aircraft has a single fuselage and wherein both wings are constructed as trapezoidal wings having an aspect ratio (AR) in the range of 12≦AR≦25, in particular 16≦AR≦24;
wherein the at least two aero engines are disposed on pylons on the upper face of the rear wing;
wherein housing tubes are provided which extend between the front wing and the rear wing; and
wherein the housing tubes are fastened to the underside of the front wing and via the pylons connected to the upper face of the rear wing.
2. The aircraft according to claim 1 , wherein the two wings of the tandem wing arrangement are vertically spaced apart in the yaw axis direction.
3. The aircraft according to claim 1 , wherein the front wing is fastened to the top of the fuselage, whereas the rear wing is fastened to the underside of the fuselage.
4. The aircraft according to claim 1 , wherein the rear wings have a greater span than the front wing.
5. The aircraft according to claim 1 , wherein the lift distribution between the lift of the front wing and the lift of the rear wing is approximately 45:55, preferably 50:50.
