Abstract

The invention discloses a photoelectric pod rack, including a reinforcement (1) and a rack (2). The reinforcement (1) is a II-type machining part with a groove and is fixed by rivets in the skin under the fuselage; the rack (2) is a centrosymmetrical cylindrical machining part; a top flange (5) of the rack (2) is provided with 4 ear piece s (6); each ear piece (6) is provided with a bolt hole; the rack (2) are screwed with the reinforcement (1) through the bolt holes on the ear pieces (6); the bottom of the rack (2) is a flange (7); 8 holes are uniformly distributed on the flange (7), which is in screw connection with photoelectric pod equipment through the 8 holes; and the tube wall of the rack (2) is provided with 4 rectangular openings (8). The invention has the advantages of simple structure, easy assembly, and good compatibility with the plane structure, avoids the adverse effect of large openings on the structural strength, and is suitable for a variety of aircrafts, particularly conducive to photoelectric pod installation on delivered aircraft.

Description

A kind of photoelectric nacelle hanger

Technical field

The invention belongs to avionics and field of airplane structure, relate to a kind of photoelectric nacelle hanger design.

Background technology

Photoelectric nacelle extensively in multiple airborne vehicle, load the airborne vehicle of this equipment can perform investigation, monitor, search and rescue, Identify, follow the tracks of, the multiple-task such as navigation, for installing photoelectric nacelle, the method the most often selected as shown in Figure 4, At ventral, construction opening is reserved when airplane design, because opening very conference causes some force transferring structures to be truncated, Have to the reinforcement structure doing complexity around opening, and for the aircraft of old model in early days, the method operates Difficulty is very big, even cannot implement.

Summary of the invention

The purpose of the present invention: propose a kind of photoelectric nacelle hanger, it is possible to compatible with multiple airborne vehicle platform, not only Can use when new machine designs, be also convenient for existing airborne vehicle is installed additional electro-optical pod.

Technical scheme: a kind of photoelectric nacelle hanger, including reinforcement (1), hanger (2), wherein Reinforcement (1) is that the Π type machine of trough of belt adds part, is fixed under fuselage on eyelid covering with rivet, and reinforcement (1) wraps Containing base plate (3), stud (4), base plate (3) downside rivets with fuselage skin, and base plate (3) upper vertical sets Vertical two studs (4), the base plate (3) between two studs (4) is provided with bolt hole；Hanger (2) is cylinder Shape machine adds part, and the centroid of hanger (2) is symmetrical, and hanger (2) top flange dish (5) is with 4 ears Sheet (6), each auricle (6) is provided with a bolt hole, and hanger (2) is by the bolt on auricle (6) Hole is spirally connected with the base plate (3) of reinforcement (1), and hanger (2) bottom is ring flange (7), ring flange (7) Being uniformly distributed 8 holes, and be spirally connected with electro-optical pod by described 8 holes, the barrel of hanger (2) is equal It is furnished with 4 rectangle openings (8).

Hanger (2) is distributed 8 ribs (9), ribs (9) upper end attachment lug (6) along barrel, adds Strong rib (9) lower end mounting flange (7), hanger (2) barrel hoop has reinforcement (10).

Advantages of the present invention

The present invention, by arranging reinforcement in fuselage interior, arranges the design of hanger at external fuselage, it is to avoid machine The impact on cylinder block strength of the big opening of body structure, especially implements easily, installs electro-optical pod joint additional for aircraft Province's funds, the present invention is good with multiple airborne vehicle platform compatibility so that cannot choose to install the aviation of photoelectric nacelle in the past Device chooses to install this equipment and is possibly realized.
