Description

 The invention relates to aircraft, and more particularly to aircraft with variable bearing surfaces, and can be used in air-to-surface aircraft.

 A known aircraft with expandable bearing surfaces (see French application N 2559894 in class F 42B 13/053), which contains a retractable feather pivotally connected to a fixed base in each expanding bearing surface.

 Also known is the BGL guided aerial bomb (UAB) (see "Foreign Military Review", N7, 1985, p. 44), which contains a plumage that is made in the form of stabilizers, each of which consists of a fixed base and a pivotally connected to it pen. The specified bomb was selected as a prototype, as it is closest to the claimed technical solution.

 The design flaws of the BGL UAB can be attributed to the fact that due to the folded stabilizers, at the time of separation from the carrier the bomb has low stability and can come into contact with the carrier under certain reset conditions.

 The aim of the present invention is to remedy this drawback, namely improving the functional and operational characteristics by increasing the safety of separation of the aircraft from the carrier.

 To achieve this goal, it is necessary to create additional aerodynamic force, which helps to separate the aircraft from the carrier and does not further affect the flight path of the aircraft.

 This goal is achieved by introducing into the design of the aircraft with the opening plumage of threaded adjusting stops installed perpendicular to the plane of symmetry of the fixed base and in its root chord in pairs, coaxially and on both sides of the retractable feather, while in the initial position, each of the stops rests on one of its ends pen. The plane of symmetry of the retractable pen is deflected using stops at a predetermined angle, which ensures the creation of additional aerodynamic force that takes the aircraft away from the carrier at the time of separation. In the open position, the retractable pen and the stops are not connected, and the plane of symmetry of the retractable pen and the fixed base are aligned. In this case, the value of the specified deviation angle of the retractable pen is within the elastic deformations.

 In Fig.1 depicts an aircraft with a drop-down plumage in the initial position, Fig. 2 section AA in the initial position, in FIG. 3 shows a section AA with stabilizers open.

 An aircraft with a drop-down plumage consists of a compartment with a payload 1, an instrument compartment 2 docked to it, on which stabilizers 3 are attached. Each stabilizer 3 consists of a fixed base 4 and a retractable stylus 5. Each fixed stabilizer 4 of each stabilizer 3 is screwed in and coaxially threaded adjusting stops located perpendicular to the plane of symmetry of the fixed base 4, and one of its end 6 retractable feather 5. Retractable feathers 5 are made protruding from the fixed base 4. The retractable pen 5 is deflected from the symmetry plane of the fixed base 4 by a predetermined angle using the adjusting stops 6. The angle is within the elastic deformations of the retractable pen 5. The plumage fixing mechanism in the initial position 7 is made, for example, in the form of shear elements, and the mechanism for opening plumage 8 in the form of a pusher.

 The device operates as follows. In the initial position, the stops 6 deflect the retractable feather 5 of each stabilizer 3 from the symmetry plane of the fixed base 4 and hold them in this position. Since the retractable feathers 5 are made protruding from the fixed bases 4, when separating the aircraft, the interaction of the deflected retractable feathers 5 with the aerodynamic flow leads to the creation of an aerodynamic force that facilitates the separation of the aircraft from the carrier.

 When the plumage opening mechanism 8 is triggered, the shear elements 7 are destroyed and the retractable feathers 5 come out of contact with the threaded stops 6, since the retractable feathers 5 deviate from the symmetry plane of the fixed bases 4 within elastic deformations, the feathers 5 retract open in position, providing their symmetrical location relative to the plane of symmetry of the fixed bases 4, and do not create disturbances during further flight of the aircraft to the trajectory and.

 The use of this technical solution makes it possible to improve functional and operational characteristics by increasing the safety of separation of an aircraft with a plumage from the carrier. In addition, the proposed design of the aircraft reduces the vibration of the retractable feathers during transportation and joint flight of the aircraft with the carrier. YYY2
