Description
Technical field
The present invention relates to model in wind tunnel support and launch input, particularly relate to a kind of high speed ejection model and quickly discharge
Device, belongs to Aerospace Engineering field.
Background technology
Model free flight wind-tunnel technique is the research method of a kind of conventional exploratory flight device unsteady aerodynamic characteristic, this
Class technology is the most repeatedly model task service.The basic skills of test is to wait in wind-tunnel in Asia across super or hypersonic, will be freely
Flying model to be fixed on the trigger mechanism of wind-tunnel tulwar, model inversion airflow direction is stably ejected at a high speed by flow field afterwards, and model is short
Meeting free flight in wind-tunnel in time, is now used high-speed photography to be shot model by observation window, can obtain flight
The attitude track of device model free flight, the later stage processes through data and just can draw the dynamic aerodynamic parameter of aircraft.
Through wind tunnel test repeatedly, the test mechanism of this type of test exposes a lot of problem, specifically includes that
1), launching pawl, to open efficiency low, causes launching pawl and model collision, affects model firing attitude, test failure rate
High, with a low credibility.In order to resist the shock loading that wind-tunnel starts, free flight model is wrapped in multi-disc and launches in pawl by test mechanism,
And in order to ensure model initial transmissions attitude, the comparison that model all can wrap is tight.Pawl will be launched together with model time model is launched
Accelerating, after piston rod arrives extreme limit of travel, the transmitting pawl of original trigger mechanism opens around its axis of rotation by self inertia, mould
Type flies out straight.
But carefully studying it finds that the design of original mechanism exists serious irrationality, this have also been obtained test in test
Card.Original mechanism utilize launch pawl, retainer ring and launch model relative speed difference produce inertial acceleration open, but due to send out
The speed penetrating pawl direction of ejection wants all standing could produce inertial acceleration, and is to closely cooperate owing to launching pawl with model surface
, the difference of the two speed necessarily causes the generation of collision, and this is inevitable.And find through test of many times checking, by
In launching, pawl rotating shaft is close apart from self barycenter, and the arm of force causing moment of inertia is the least, and inertia force is not that continuous action is being sent out
Penetrate the power on pawl, but launching a power of the of short duration existence of coda, and test shows to be about 0.5 milli the action time of inertia force
Second, all these parameters all illustrate that moment of inertia is limited to launching the pawl effect of opening, and which results in appearance in test
Launch pawl and open extremely inefficient problem.And the emission rate of model is about 15m/s in supersonic flow field, high-speed photography is clapped
The picture display taken the photograph is launched pawl and to be opened within the millisecond magnitude time just without interference with model attitude, this inertia requiring to launch pawl
Moment the biggest could realize.Original mechanism different design closes the principles of science, there is also that action time is short, moment of inertia simultaneously
The problem such as the biggest result in the transmitting pawl of original trigger mechanism and easily collides with model, causes test failure.This becomes
The difficult problem that original mechanism cannot overcome, test mechanism must improve.
2), rigid impact cause part deformation, mechanical stability is poor.When each model of original mechanism is launched, steel piston
All with copper cylinder front pods generation rigid impact to reach deceleration purpose, after test of many times find rigid impact cause piston and
Cylinder front pods endoporus all deforms, and interferes between part, and piston movement resistance becomes big, and the most stuck, this causes mechanism
Poor stability, model emission effciency step-down, use extremely inconvenience, need to improve.
3), model firing attitude is single, it is impossible to meet more polytypic mission requirements.Original mechanism can only be by model according to solid
Fixed attitude angle ejects forward, and increasing model task to need model not only to have during free flight certain
Initial angle, in addition it is also necessary to have certain angular velocity, and original mechanism can not reach this target, needs to improve.
4), model emission rate repeatability the highest, affect test effect, even and if master cylinder piston bar at bleed pressure very
All can seem in the case of height and lack of staying power, original mechanism needs to improve.In order to more preferably pick out model by aerodynamic force, every time
Test us to be intended to photograph picture as much as possible.Concrete form is: model arrive observation window leading edge time and wind-tunnel
Relative velocity reduces to 0, the most slowly to observation window trailing edge backward.This model flight pattern needs model emission rate to have
The highest multiplicity.
