Description
Technical field
The present invention relates to aircraft manufacturing field, particularly relate to a kind of installation structure of helicopter earth observation device.
Background technology
Helicopter earth observation equipment is indispensable instrument helicopter obtaining ground observation data, have observation method various, the feature such as to be widely used.Existing helicopter earth observation equipment mounting means comprises head rotary type tower, forward fuselage structure formula and rotor shaft rotary type.Head rotary type tower is installed on helicopter head place, but is generally used for installation airborne radar herein; Forward fuselage structure formula is installed on forebody side, but forebody both sides are generally provided with emergent floating drum; Rotor shaft rotary type is large owing to having rotor inertia, gives prominence to and limit its use to the impact of helicopter control and stability.Because helicopter earth observation equipment is numerous, not only there is TV/infrared/laser gondola, take the photograph photographic camera, radar, also comprise optical spectrometer, boat magnetic machine etc., existing earth observation equipment mounting means is difficult to fully meet the complete requirement of helicopter earth observation means due to itself feature, and then limits the application of helicopter earth observation equipment.
Summary of the invention
The technical problem to be solved in the present invention: design a kind of installation structure of helicopter earth observation device, not by the restriction of existing helicopter earth observation equipment installation site.
Technical scheme of the present invention: a kind of installation structure of helicopter earth observation device, comprising:
A transition platform, transition platform comprises a cell type part, screw hole cell type part having the opening consistent with earth observation equipment capstan head top bore and connect; An earth observation equipment is installed and maintenance lid; Transition platform also comprises upper and lower covering and front and back and sidepiece fairing, respectively supports front and back covering by an angle section before and after cell type part.Cell type part is bolted on the strengthening rib of camber beam by two rows.
A camber beam, camber beam comprises three strengthening ribs arranged between front and back longeron, front and back longeron, upper and lower covering, side, front and back fairing.The front end of camber beam supports front side fairing by three angle sections, and rear end supports rear side fairing by two angle sections.Front side member is with the ears sheet be connected with top connection before helicopter.
A structure transition apparatus, structure transition apparatus comprises a monaural angle section be connected with camber beam floor side member; Two ends are with the transition structure part of ears sheet; An ears sheet be connected with top connection after helicopter; A monaural angle section be connected with camber beam strengthening rib, two ends are respectively with the connection pipe of monaural sheet and ears sheet, and two auricles are connected with thread forms with connection pipe, so that adjustment during assembling; An ears joint, is connected with lower adaptor after helicopter.
Connecting bridge on a machine, on machine, connecting bridge comprises four permanent joints, rivets or is bolted on helicopter structure, is fixed by self-locking screw with structure transition apparatus and camber beam.
Beneficial effect of the present invention: by change earth observation equipment camber beam course width and section shape, structure transition apparatus connector interface size and towards, transition platform interface size thus meet the installation requirement of different tonnage, the helicopter of different aerodynamic configuration and distinct interface size, dissimilar helicopter earth observation equipment, there is the features such as commonality is good, applicability is strong.
