Description
Technical field
The utility model relates to rudder wing technical field more particularly to a kind of rudder wingfold mechanisms.
Background technique
Folding rudder wing type steering engine is to seek the emitter of miniaturization in tactical missile so that transmitting, transport, storage are simple
Grow up in convenient situation.For guided missile, lateral dimension is reduced, convenient for the storage of case (cylinder) formula, transport and hair
It penetrates, saves the storing space of guided missile, increase the storage capacity of storing and transporting equipment, improve the fight capability of weapon system.
Folded surface is generally made of the part such as flexible wing face, fold mechanism and energy.Fold mechanism generally includes to fold
Unfolding mechanism, synchronization mechanism, location locking mechanism, release mechanism etc..The effect of folding and expanding mechanism is aerofoil can be made to fold,
Aerofoil in folded state can again expanded in place under certain condition.Synchronization mechanism be same after keeping the expansion of each pair of aerofoil
When in place and be arranged.The effect of locking positioning mechanism is that the movable wing for making to fold is accurately positioned in predetermined position, Er Qieke
It is locked by ground, and bears and transmit design load.
Differently, folding wings can have different classification.It is divided into all-wing folding by the tangential parting surface position of folding wings
It folds and partially folded two kinds.Partially folded folding wings, tangential parting surface is not in wing root, and in the middle part of aerofoil, therefore has and bomb body
The wing centre section of connection exists.By folding movement direction point, there are laterally folded formula and longitudinal folding formula.Laterally folded aerofoil is in aerofoil
Root or middle part, along airflow direction be arranged a tangential parting surface, make outer wing part can around on parting surface shaft foldable or exhibition
Open and longitudinal folding aerofoil expansion the direction of motion be consistent with the body longitudinal axis, the rotary shaft of aerofoil folded portion all with body indulge
Axis is vertical.By the energy point of expansion power, there are spring force formula, compressed air active force formula, gaseous-pressure formula and hydraulic actuation cartridge type
Deng.
The appearance of guided cartridge is employed for collapsible steering engine quickly on the body of common projectile, gathers around common projectile
There is the ability of precise guidance.However the restriction by shell launching condition, shell must be in close contact when emitting with bore wall.
Therefore, the various folding modes of rudder wingfold mechanism not necessarily all can be suitably used on guided cartridge.In view of grinding product miniaturization
The characteristics of, existing rudder wingfold mechanism can not be also utilized in the spatial dimension of small size.

Contracting state, it is entirely in-house to be in dynamic balance state, it remain stationary, to achieve the purpose that fold rudder wing ontology.Quality
Sliding block is under the action of the impact acceleration and vibration acceleration that body transmitting generates, since inertia emits opposite direction along body
Movement, spring continuation are compressed, and the torsion of torsional spring rotates rudder wing ontology upwards when not constrained by quality sliding block, then rudder
Wing ontology bounces rapidly, meanwhile, because of the presence of torsional spring, rudder wing ontology can also be always maintained at the state bounced.The utility model
Mechanical structure it is simple, realize miniaturization, reached body transmitting front rudder wing ontology be in fold, transmitting after rudder wing ontology it is fast
Speed is unfolded and keeps the good result of locking.
Further, the quality sliding block is equipped with 4 card slots, is equipped with rudder wing ontology in each card slot.
Further, the mounting rack is threadedly coupled with the guide post.
Further, the guide post is equipped with 4, and 4 guide posts are arranged on mounting rack at equal intervals.
The utility model has the beneficial effect that compared with prior art
Screw rod and quality sliding block are connected through a screw thread, when screw rod is in threaded hole of the gradually knob into quality sliding block, if
The spring set in fixing groove is compressed, and the elastic force of spring is transmitted to quality sliding block by screw rod, so that quality sliding block is received downwards
Tightly, it is fixed before the expansion of rudder wing ontology by the card slot of quality sliding block, spring and torsional spring are in compressive state, entire in-house
It in dynamic balance state, remain stationary, to achieve the purpose that fold rudder wing ontology.Quality sliding block is generated in body transmitting
Under the action of impact acceleration and vibration acceleration, since inertia is moved along body transmitting opposite direction, spring continuation is compressed,
The torsion of torsional spring rotates rudder wing ontology upwards when not constrained by quality sliding block, and then rudder wing ontology bounces rapidly, meanwhile,
Because of the presence of torsional spring, rudder wing ontology can also be always maintained at the state bounced.This law mechanical structure is simple, realizes miniaturization,
Reach rudder wing ontology rapid deployment after body transmitting front rudder wing ontology is in folding, emits and keeps the good result locked.
It takes up space small, structure is simple.
