The invention refers to a quick released system for coupling (1) and drogue (2) assembly comprises a crown coupling connector (4) suitable for being fixed to the coupling (1) and comprising cavities (14); a plurality of balls (3) housed in the cavities (14) with an emerging part and radially movable
The invention refers to a quick released system for coupling (1) and drogue (2) assembly comprises a crown coupling connector (4) suitable for being fixed to the coupling (1) and comprising cavities (14); a plurality of balls (3) housed in the cavities (14) with an emerging part and radially movable; a crown drogue connector (5) suitable for being fixed to the drogue (2), configured to engage and disengage the coupling connector (4) and comprising first recesses (26); and a crown locking ring (6) rotatable between a locked and a released position and comprising second recesses (31). The second recesses (31) are arranged in correspondence with the first recesses (26) when the system is in a released position and, the locking ring (6) in contact with the balls (3) and the first recesses (26) engaged with the emerging part of the balls (3) when the system is in a locked position.

1. A quick release system for a coupling (1) and drogue (2) assembly of a hose and drogue system for in-flight refueling, the quick release system comprising: a coupling connector (4) suitable for being fixed to the coupling (1), the coupling connector (4) having a circular crown configuration with
1. A quick release system for a coupling (1) and drogue (2) assembly of a hose and drogue system for in-flight refueling, the quick release system comprising: a coupling connector (4) suitable for being fixed to the coupling (1), the coupling connector (4) having a circular crown configuration with outer (17) and inner (18) surfaces, wherein the coupling connector (4) includes a plurality of passing-through cavities (14) arranged in radial positions around the crown and wherein each cavity (14) has accesses from both surfaces (17, 18);a plurality of metallic balls (3) housed in the cavities (14) and radially movable therein, each ball (3) having a diameter smaller or at least equal than the outer surface (17) access and larger than the inner surface (18) access, so that each ball (3) can have a partially emerging part through the inner surface (18) access;a drogue connector (5) suitable for being fixed to the drogue (2) and configured to engage and disengage with the coupling connector (4), the drogue connector (5) having a circular crown configuration and having a parametric wall (25) configured to engage with the inner surface (18) of the coupling connector (4), said parametric wall (25) having a plurality of first recesses (26) around the crown in correspondence with the cavities (14) positions;a locking ring (6) having a circular crown configuration having a contacting surface (30), wherein the locking ring (6) is mounted on the outer surface (17) of the coupling connector (4) and being rotatable between a locked position and a released position, the locking ring (6) having a plurality of second recesses (31) around the contacting surface (30) of the crown in correspondence positions with the first recesses (26), the second recesses (31) configured to receive a part of the balls (3) when they are radially moved,wherein the second recesses (31) are arranged in correspondence with the first recesses (26) when the system is in a released position, such as the system is disengaged, and,wherein the contacting surface (30) of the locking ring (6) is in contact with the balls (3) and the first recesses (26) are engaged with the emerging part of the balls (3) when the system is in a locked position, such as the system is engaged. 2. The quick release system of claim 1 further comprising a circlip (7), and wherein the coupling connector (4) has an end suitable for being fixed to the coupling (1) and a free end, and a circumferential groove (15) provided at its free end configured to receive the circlip (7). 3. The quick release system of claim 2, wherein the drogue connector (5) comprises a thickened rim (24), said rim (24) configured to match the circlip (7). 4. The quick release system of claim 1, wherein the coupling connector (4) and the locking ring (6) comprise at least one outwardly extended radial projection (16, 8). 5. The quick release system of claim 4, wherein both the coupling connector (4) and the locking ring (6) include two outwardly extended radial projections (16, 8) at diametrically opposed positions. 6. The quick release system of claim 4, wherein at least one of the outwardly extended radial projection (16, 8) comprises a hole (9, 10). 7. The quick release system of claim 1 further comprising a locking means for retaining the quick release system in a locked position. 8. The quick release system of claim 7, wherein the locking means includes locking pins (27) introduced into the coupling connector (4) and locking ring (6) holes (9, 10), and wire (28) to fix the projections (16, 8) of the coupling connector (4) and the locking ring (6) together. 9. The quick release system of claim 1, wherein the parametric wall (25) of the drogue connector (5) has a flared end (29). 10. The quick release system of claim 1, wherein the coupling connector (4) and the drogue connector (5) include threaded holes (11, 21) for fixing the coupling connector (4) and the drogue connector (5) include threaded holes (11, 21) with the coupling (1) and with the drogue (2). 11. The quick release system of claim 1, wherein the cavities (14) of the coupling connector (4) are of spherical shape. 12. The quick release system of claim 1, wherein the first recesses (26) of the drogue connector (5) are of cylindrical shaped. 13. The quick release system of claim 1, wherein the second recesses (31) of the locking ring (6) are of cylindrical shaped.
