Description
Technical field
It the utility model is related to low thrust jet nozzle feeder in a kind of wind tunnel test, and in particular to a kind of wind-tunnel spray
Stream tests the single jet pipe of medium and small propelling nozzle, the high-pressure air feed device of multi nozzle combination, belongs to wind-tunnel technique field.
Background technology
With the gradual development of contemporary aircraft, jet control is short with its reaction time, and control efficiency is high, suitable at full speed
Domain, full spatial domain, small, the features such as stealth effect is good is influenced by environment and speed, and is used by numerous aircraft.When jet flow works,
Acted on board the aircraft by three kinds of modes：First, the thrust of jet flow itself, thus it is possible to vary the flight attitude of aircraft or
Track；Second, the suction ejector action of jet flow, takes away the air on surface near jet pipe, produces low pressure zone, this low-pressure area
Itself thrust direction of action direction and jet flow is opposite；Third, the outgoing of jet flow can cause to block to incoming, formed in spout upstream
Higher-pressure region, further influences jet flow itself thrust.Above-mentioned Article 2, Article 3 influence to cause the generation of aircraft surface flow field huge
Change, it is possible to create the power and torque opposite with jet direction, offsets the effect of even reverse jet flow, and therefore, jet flow is to flight
The influence of device aerodynamic characteristic must be studied.
Jet control is divided into two ways according to purposes：Attitude control jet, applied to normal direction, lateral, pitching, yaw, rolling
Deng the gesture stability of passage, installation site, controling power and torque are different, feature be away from barycenter, thrust it is small, in chamber pressure
Greatly, flow is small；Rail control jet flow, applied to the orbits controlling of aircraft, feature be proximate to barycenter, thrust it is big, in chamber pressure is small, stream
Amount is big.In actual aircraft, jet flow is provided by engine gas, can meet the jet power demand of various uses.And on ground
Interview is tested, and realizing for true jet engine combustion gas stream be complex, there are problems such as explosion danger, environmental pollutions,
It can not possibly be used for the acquisition of mass data, therefore, Russian proposes feasible wind tunnel test methods within 1964, using high pressure
Air simulates actual engine combustion gas as jet flow medium, and more than 60 years in the past, and present cold hot jet simulation technology is ripe day by day.
In wind tunnel test, rail control jet nozzle (abbreviation rail control jet pipe) and Attitude control jet jet pipe (abbreviation attitude control jet pipe) basis
The difference of thrust size, generally there is two kinds of mounting structures.The first is known as the connection of separate type, and jet pipe is separated with model, the two
It does not interfere with each other, balance measurement model aerodynamic force and perturbed force, but not measures jet flow thrust, such case is suitable for jet flow thrust
With model aerodynamic force on the same order of magnitude or when few an order of magnitude, such as rail control jet flow and the larger attitude control spray of thrust
Stream；Second of referred to as monoblock type connection, jet pipe connect together with model, balance measurement model aerodynamic force, jet flow thrust and jet flow
Perturbed force, suitable for the less situation of jet flow thrust.
Because independence in room, jet pipe separates separate structure with model, so, same room of staying can be for multiple jet pipes at the same time
Supply, number can increased or decreased；Jet pipe is connected on room when working, will closure in room when jet pipe does not work.Because jet pipe and mould
Gap between type can lose the confusion area of jet flow, reduce the Jet enterference power that can be measured, cause wind-tunnel measurements distortion, institute
During testing, when needing, the jet flow thrust that measures and pneumatic perturbed force are smaller, when accounting for less than the 1% of model whole aerodynamic force, point
From formula structure with regard to improper.
Monolithic construction can retain the confusion area of jet flow well, but it is there is also problem, the spray with sharp processing
Pipeline section repeatability precision is difficult to ensure that；The same jet pipe quantity that can be supplied in room cannot arbitrarily increase and decrease, unlike separate type
It is easy for installation；And pipeline may be impacted by repeatedly assembling and disassembling nozzle section, gas leakage cannot be tested, more seriously damage equipment or
The person is damaged.
After actual aircraft is by a reduced ratio, the size and thrust of its Attitude control jet jet pipe are all smaller, sprays
Stream thrust, jet flow and perturbed force (abbreviation perturbed force) value caused by incoming interaction only account for model aerodynamic force itself (referred to as
Aerodynamic force) 1% less than.If using separate type, then the perturbed force of jet flow is unable to complete measument；If every kind of jet pipe is all processed
One nozzle section, then process funds, set-up time, model damaged degree all greatly increase, and experimentation cost and difficulty will also improve
Very much.
Such as the venturi of jet pipe is less than 1mm, the thrust of jet flow is less than 1N, jet flow torque 0.5Nm or so, and model is pneumatic
Power reaches 600N, and moment values reach 12Nm.In another example the jet pipe of the symmetrical aircraft in certain face is located at afterbody, jet pipe 1, the outgoing side of 2 jet flows
To vertical, for controlling pitching and the roll attitude of aircraft；Jet pipe 3, the exit direction of 4 jet flows are horizontal, fly for controlling
The sideslip of device and roll attitude；45 ° of the exit direction angle with horizontal plane of jet pipe 5,6 jet flows, for control aircraft pitching,
Break away, roll attitude；The exit direction of 7 jet flow of jet pipe is used for the roll attitude for controlling aircraft.Jet pipe 1~7 all may be individually
Work, and the possible work in combination of jet pipe 1~7, up to tens kinds of jet flow combination.According to separation design, then jet flow pushes away
Power and its perturbed force fundamental measurement are less than according to traditional integral design, then processing capacity is huge, and model installation accuracy is difficult to
Ensure.
Low thrust jet nozzle device and method is the improvement in monolithic construction, the former had both remained Jet enterference area
Area, and realize on same nozzle section, the increase and decrease of jet flow number；Effectively reduce model and replace number, ensure model
With the integrality of supply air line.The latter then simply can retain Jet enterference area area, can not realize the mesh for simplifying test procedure
, while the processing capacity of model is more compared with the former, experiment hidden danger is larger.
