Problems solved by technology

The disadvantage of such equipment is the limited installation space available and the limited capacity for carrying structural aerodynamic loads in the area of ​​​​the rudder assembly
It was also found that the yaw stabilizing effect of the rudder assembly was significantly reduced when such equipment was used
For the above reasons, this type of equipment can only provide a low level of achievable resistance

Embodiment Construction

[0025] figure 1 An aircraft 2 is shown with two wings 4 equipped with leading edge flaps 6 (slats) and trailing edge flaps 8 (flaps). Both the flaps 8 and the slats 6 are deployed during the landing approach and provide a greatly increased lift coefficient compared to cruising flight and allow the flight speed to be significantly reduced during the landing approach.

[0026] During a landing approach, in view of the prolonged descent flight, in addition to the reduction in thrust and the increase in the overall air resistance of the aircraft due to the deployed slats 6 and flaps 8, it is necessary to further reduce the aircraft 2 by braking the flaps speed or keep it constant. This is achieved in the present example by means of two braking flaps 10 which are arranged in the region of the aircraft fuselage 12 above the plane defined by the wing 4 .

[0027] The braking flaps 10 have a configuration such that, in their most extended position, they are substantially perpendicul...

Abstract

The invention concerns an apparatus for and a method of producing aerodynamic resistance on an aircraft, comprising at least one braking flap, wherein the at least one braking flap can be extended into the airflow around the aircraft. In accordance with the invention at least one braking flap is arranged on the fuselage of the aircraft in a region over the wings of the aircraft.

Description

technical field [0001] The invention relates to a device and a method for generating aerodynamic drag on an aircraft, said device having at least one braking flap, wherein the at least one braking flap can be deployed into the airflow surrounding the aircraft. The invention also relates to an aircraft equipped with at least one braking flap, wherein said at least one braking flap is deployable into the airflow surrounding the aircraft. Background technique [0002] During a landing approach of the aircraft, the speed of the aircraft is reduced to the lowest possible value in order to limit the length of the required landing runway. Furthermore, in order to reduce flight noise on the ground, it is desirable to minimize the area of ​​noise pollution by means of a near-vertical landing approach. For this, a high lift coefficient is required in order to be able to provide low speed approaches. In order to achieve a near-vertical and low-speed approach flight path, in addition ...
