Description
Technical field
The invention belongs to aerostatics tests, field of taking a flight test.Aerostatics static balance attribute testing technical field is particularly belonged to, is fitted
Static balance characteristic ground experiment technology for flexible body aerostatics.
Background technique
Aerostatics Limit of Wind Speed static balance attribute testing is to test the important means of aerostatics performance, mainly there is wind-tunnel at present
Two kinds of test methods of free flight test of test and true environment.
Wind-tunnel technique：One of static balance specificity analysis main means of aircraft are exactly using wind tunnel test data as base
Plinth is analyzed, but since large and medium-sized captive balloon is soft structure, length is even more big up to 50m, and when wind tunnel test is necessary
Carry out model contracting ratio, but contract ratio after, mold strength, rigidity be difficult to completely it is similar, buoyancy is similar to be more difficult to accomplish, access phase
Document and patent are closed, without finding the wind tunnel test similarity criterion or test method of soft stressed-skin construction, therefore can not be used
Soft model wind tunnel test completes this item work.
The free flight test of true environment：Captive balloon is anchored by tether cable in ground, unpowered systems, therefore
Under natural conditions, it is difficult to directly progress free flight test；For the wind loading rating of captive balloon up to 40m/s, this weather can simultaneously
Chance can not be asked, therefore the free flight of captive balloon is difficult to be simulated in true environment.
Summary of the invention
It is the safety of captive balloon object of the present invention is to simulate the static balance characteristic of captive balloon by ground towing trial
Property design with early warning provide a kind of effective, reliable Laboratory Simulation.
The Limit of Wind Speed static balance specificity analysis of captive balloon is completed by the method that ground trailer pulls.Experimental design
When, certain contracting can be formulated according to factors such as trailer performance, buoyancy, aerodynamic force, gravity, and than ratio, (contracting is than ratio no more than 5:1,
Far smaller than wind tunnel test contracting is more nearly legitimate reading than ratio), and the model after the ratio that contracts guarantees suffered by captive balloon
The same contracting ratio of external force and torque, to guarantee that static balance characteristic can reflect the characteristic of true captive balloon.
When towing trial, tether cable is connected on the winch of trailer, and towing trial balloon and tether cable, drag winch
The towing trial system that vehicle forms a whole simulates the wind speed that towing trial balloon is subject to, analysis by trailer travel speed
Influence of the wind speed to towing trial balloon.
The technical scheme is that：

Property.
Beneficial effect
According to this invention, the contracting of captive balloon can be made to reduce than ratio, captive balloon is smaller or trailer power foot
In the case where enough, even without contracting ratio is accomplished, that is, true captive balloon can be used and pulled, even if carrying out contracting ratio, contracting ratio
Ratio is also smaller, and contracting is not more than 5 than ratio:1, far smaller than wind tunnel test contracting is than ratio (the wind tunnel test contracting ratio that early period carries out
Ratio reaches 45：1), be more nearly legitimate reading, and hawser, buoyancy, gravity and related torque can be simulated etc., compare wind-tunnel
It tests more true；By contracting than criterion (aerodynamic force, gravity, buoyancy and related torque same contracting ratio) establish scale model
Mechanical characteristic, test result can reflect the static balance characteristic (pitch angle variation) of true captive balloon；Moreover, pass through
The technology, also can analyze the influence to captive balloon static balance characteristic such as hawser, lift-off height, internal pressure, and raising is tethered at gas
The level of ball safety Design.
