Fig. 5 is the software architecture diagram of the present invention in the integrated design platform of solid propellant rocket is implemented.
The concrete building method and the structure of this platform are described below in conjunction with a typical solid rocket engine powder column design cycle:
The design object of present embodiment is solid rocket motor grain of design; Fig. 6 is the original flow process of the typical solid rocket engine powder column design of collecting before the design, and this flow process comprises: 1) specify desirable thrust-time plot of height above sea level and hypothesis; 2) set propellant type, combustion chamber pressure, burning area and jet pipe physical dimension; 3) set the propellant shape; 4) calculate thrust and specific impulse.If thrust and specific impulse are suitable; Just obtained a kind of potential feasible design scheme,, just need return for the 3rd step and revise the propellant shape if improper; If it is still improper; Just returned for second step and continue to revise,, just need return first step modification thrust-time curve if still can not get thrust and the specific impulse wanted.
Step 1 according to design object, is collected data and the resource that need use in this design process.
Step 2, the grouping of data arrangement that step 1 is collected is stored into database, forms the Various types of data library file of format specification.
Step 3 through type of database and the file that generates according to concrete design object in the step 2, is constructed each effector.
Step 4, platform design person confirms that through the original flow process of this concrete design of research this flow process can realize with the gang form mode like Fig. 7.According to this array mode, need to generate four independently templates.Fig. 8-Figure 11 has showed the concrete structure and the function of these 4 independent templates:
Fig. 8 has showed the 26S Proteasome Structure and Function of template 1.At first; ATT (height above sea level, thrust, time) is input to the template middle layer through input layer; The knowledge integration module in middle layer can be searched for similar product according to ATT from knowledge base; Can from product database, read information such as product parameters in some cases, these parameters are integrated in the template through the knowledge integrator, and ATT and SPP (like product parameter) can be outputed in the next template subsequently.
Fig. 9 has showed the 26S Proteasome Structure and Function of template 2.At first, ATT and SPP are input to the template middle layer through input layer.Subsequently, the propellant in middle layer selects module from normative database, to search for the propellant selective rule according to input, and this rule is grown up to be a useful person through specifications set and is integrated in the template subsequently, selects suitable propellant to help the user; One group of combustion chamber pressure, burning area, jet pipe physical dimension can be supposed through SPP in the middle layer then.After the propellant type is selected; Can from product database, read the characteristic parameter of this propellant; It is embedded into template inside; At last with ATT, SPP, CBN (combustion chamber pressure, burning area, jet pipe physical dimension) and PCP (propellant characteristic parameter) are delivered in the middle of the next template as output.
Figure 10 has showed the 26S Proteasome Structure and Function of template 3.After obtaining input; The grain configuration in middle layer selects module from normative database, to search for the grain configuration selective rule according to input; This rule is grown up to be a useful person through specifications set and is integrated in the template to help the user to select grain configuration, like shapes such as wheel shape, star and dendriforms; The burning performance parameter of this shape also can be integrated in the template simultaneously, and when selecting a kind of powder column, this selection result GS (grain configuration) can be imported in the middle of the next template.
Figure 11 has showed the 26S Proteasome Structure and Function of template 4.As all design parameter (SPP; CBN, PCB GS) is input to after this template; The powder column in middle layer burning computing module will be from relevant set of algorithms searching algorithm; These algorithms are grown up to be a useful person through set of algorithms and are integrated in the template, and subsequently, the powder column burning is calculated these different algorithms of module invokes and calculated specific impulse (I
Sp) and thrust (Thrust), the user can therefrom do and relatively obtain the higher result of fiduciary level.If thrust and specific impulse meet the demands, so just obtained a kind of potential feasible design proposal, if do not satisfy, just return template 3 or template 2 or template 1 and restart design.
Step 5 is in the same place four form assemblies that step 4 generates with data stream according to the logic flow that the flow process resolver is parsed, and forms a solid rocket motor grain design platform based on template, and its sketch is as shown in Figure 7.
In the platform user use; Only with the input and output of operating each template; And the complex operations, the complicacy conversion of isomeric data, complex rule, the complicated algorithm that need not to focus onto software design; Simultaneously can also be real-time in design process call existing knowledge as a reference, to reach the purpose of quick design.
In this case, the user uses the time of a design of this platform renders to be merely tens minutes, and does not use this platform and use the additive method of prior art to reproduce this design and need expend several hours at least.When in the face of new product designs the time; Owing to need more design parameter change and iteration; Use this platform can significantly reduce the quantity of user operation, can reduce design time 30% at least, and user's income that obtains that from heavy software operation, frees can't be estimated.
Above-described specific descriptions have been carried out further explain to purpose, technical scheme and the beneficial effect of inventing, and institute is understood that; The above is merely specific embodiment of the present invention; Be used to explain the present invention, and be not used in qualification protection scope of the present invention, all within spirit of the present invention and principle; Any modification of being made, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
