AERODYNAMIC LAYOUT OF A CONTROLLED GLIDING AERIAL BOMB Russian patent published in 2022 - IPC F42B10/00 F42B25/00 

FIELD: aviation technology.

SUBSTANCE: invention relates to aviation technology, in particular to guided aerial bombs. A guided gliding aircraft bomb (GGAB) contains a hull that consists of sequentially connected bow, center and aft parts. The bow of the body at the base has a square shape with a square side of length ɑ and passes into a sphere at the top of the bow. The central part is made square in cross-section with the side of the square length ɑ. The aft part has a square shape with the side of a square with a length of ɑ at a larger base, smoothly turning into a smaller base of circular cross section, while the side of the square with a length of ɑ is located at an angle of ϕ=45° relative to the vertical plane of symmetry. Body length Lf= 14.4ɑ. In the central part of the body, there are vehicle suspension elements and the wing made using the biplane aerodynamic scheme consisting of four consoles with magnitude equal to Lk=11.1 ɑ and Lk=2.25 a, respectively, for the expanded and retracted position of the wing, with angles of sweep on the leading edge of χ₀≈30° and χ₀≈84.5°, respectively, for the expanded and retracted position of the wing with a chord of the wing equal to b=0.67 a, with a curved double convex profile, the relative thickness of which is the relative concavity of the profile . The wing consoles in the open and retracted positions are interconnected by end posts in the form of flat plates with a height equal to h_p =ɑ and a chord equal to b_p = 0.5b, with a relative thickness equal to , located in the open position of the wing parallel to the chord of the wing consoles, along the flow, and in the retracted position at an angle of α_p≈57°.

EFFECT: creation of an aerodynamic layout of the GGAB, which implements longer flight ranges than analogues.
