s2: setting a reference state of a flight platform;
s3: after the flying platform is adjusted to a reference state by using the mechanical control surface, locking the mechanical control surface;
s4: and controlling the flight platform by utilizing the jet flow control surface to verify the control performance of the jet flow control surface.
In the verification process, after the flight platform is adjusted to the reference state by the mechanical control surface, the control performance of the jet flow control surface is verified by controlling the flight platform by the jet flow control surface. On the other hand, the jet flow control surface is not needed to be adopted when the flying platform is adjusted to the reference state, the use ratio of the jet flow control surface in the verification process is reduced, the control performance of the jet flow control surface of the flying platform is not needed to be tested on the premise of ensuring the balance of the flying platform in the reference state, and the control performance of the jet flow control surface of the flying platform in the reference state is directly verified.
That is to say, once the jet flow control surface actuates, its effect of actuating can directly reflect on the attitude change of flight platform, can verify and aassessment the control performance of jet flow control surface more accurately.
Compared with the mode that the control performance of the jet flow control surface is verified after the flight platform is adjusted to the reference state by the jet flow control surface, the energy efficiency of the part of the jet flow control surface for enabling the flight platform to keep the reference state is not required to be deducted in the verification process, the verification difficulty is greatly reduced, and the accuracy of the verification result is improved.
As the mechanical control surface is a traditional mature technology, the flying platform is adjusted to the reference state by adopting the mechanical control surface, and the stability of the reference state and the controllability of the experimental process are better ensured. If the jet control surface is used for replacing a mechanical control surface to adjust the flight platform to the reference state, the control performance of the jet control surface needs to be verified, the actual control performance of the jet control surface is not mastered enough, the difficulty that the flight platform is stably kept in the reference state by the jet control surface is high, and the verification of the jet control surface needs to be continuously carried out subsequently on the basis of the reference state, so that the flight state of the flight platform is very unstable, the potential risk is very high, the safety of the verification process cannot be guaranteed, and the reliability of the verification result cannot be guaranteed.
Through the special design of the technical scheme of this embodiment, overcome above problem effectively, the technical risk and the safety risk of greatly reduced efflux verification process effectively ensure the accuracy and the security of efflux verification process for efflux verification process can reliably, stably implement, has reduced the technical degree of difficulty of efflux verification process.
On the basis, as the mechanical control surface and the jet flow control surface are arranged on the flight platform at the same time, different reference states can be preset, and then the control performance of the jet flow control surface is verified respectively under the different reference states, so that under the condition of keeping the adjustment range of the jet flow control surface unchanged, the actual verification range of the jet flow control surface on the flight platform can be effectively widened, the attitude regulation and control limit of the aircraft can be more accurately determined, positive significance is provided for mastering the actual performance and the performance limit of the aircraft, and reference is provided for the use safety standard of the aircraft. These all contribute to the push for the intensive research and practical application of jet control technology.
Referring to fig. 2, in the present embodiment, the method for verifying the jet control flight further includes the following steps:
s5: and when the jet flow control surface is abnormal, closing the jet flow control surface and activating the mechanical control surface.
When the jet flow control surface is abnormal, after the jet flow control surface is closed, the mechanical control surface still keeps the deflection state in the previous reference state, and once the jet flow control surface is closed, the flying platform can return to the previous reference state again under the action of the mechanical control surface. In order to ensure the safety of the flying platform in the process of returning to the previous reference state, the mechanical control surface is reactivated, the mechanical control surface can be reasonably adjusted according to the actual attitude of the flying platform, and the flying platform can more stably and safely return to the trim state.
Through the design, the safety of the verification process can be effectively improved. If not set up mechanical control surface, appear unusually as the efflux control surface, no matter continue to open the efflux control surface or directly close the efflux control surface, all lead to the flight platform to destroy easily. The technical scheme of the embodiment can solve the problems, and the safety of the flight platform can be still ensured under the condition that the jet flow control surface is abnormal.
Further, referring to fig. 3, step S5 includes the following steps:
s51: determining the failure direction of the jet flow control surface when the jet flow control surface is abnormal;
s52: closing the jet flow control surface in the failure direction;
s53: the mechanical control surface in the failure direction is activated.
When the jet flow control surface is abnormal, if the jet flow control surface is not completely unusable, the failure direction of the jet flow control surface can be determined firstly, the actual failure condition of the emergent jet flow control surface is evaluated, if the regulation and control capability is lost in some directions, such as one or both of transverse direction, longitudinal direction and yaw, the jet flow control surface in the failure direction can be closed only, the control authority of the jet flow control surface which is not failed is reserved, and meanwhile, the mechanical control surface in the failure direction is reactivated.
And in the failure direction, the flight platform is controlled again by utilizing the mechanical control surface so as to ensure the safety and the stability of the flight platform. And in the direction without failure, the jet control surface in the direction can still work normally, so that the verification work of the jet control surface in the direction can be continued.
Specifically, referring to fig. 4, step S5 further includes the following steps:
s54: and after the flying platform returns to the reference state in the failure direction, the flying platform is controlled by the jet control surface in the non-failure direction so as to continuously verify the control performance of the jet control surface.
Through the design, the safety of the flight platform is guaranteed, the fault resistance and the risk resistance of the verification process are greatly improved, the verification process can be carried out to the greater extent, the condition that the whole verification test is interrupted due to the fact that one part of the jet flow control surface breaks down is avoided, the verification progress is improved, and the verification cost can be reduced.
Referring to fig. 5, the method for verifying the jet control flight further includes the following steps:
s6: and verifying the attitude callback performance of the mechanical control surface in the process that the flying platform returns to the reference state through the mechanical control surface.
When the jet flow control surface is abnormal, the mechanical control surface returns to the reference state again in the failure direction, in the process, the attitude callback performance of the mechanical control surface on the flight platform can be verified, the actual guarantee capability of the mechanical control surface on the safety of the flight platform is evaluated, and therefore the jet flow control surface can be matched with the appropriate mechanical control surface for different jet flow control surfaces in the subsequent verification process, so that the safety requirement is met.
Further, referring to fig. 6, in the present embodiment, step S3 includes:
s31: selecting a verification direction;
s32: adjusting the flying platform to a reference state in the verification direction by using a mechanical control surface; and
s33: the machine control surface is locked in the verification direction.
Step S4 comprises the following steps: and controlling the flight platform by utilizing the jet flow control surface in the verification direction so as to verify the control performance of the jet flow control surface in the control direction.
In the actual verification process, if the control performance of the jet flow control surface in some directions only needs to be verified, the directions can be selected as verification directions, and the control performance of the jet flow control surface in the verification directions is verified in a targeted manner. This is advantageous in improving the verification efficiency.
In order to further improve the safety of the verification process and the pertinence of the verification of the jet control surface, the step S33 includes: and the control authority of the mechanical control surface in the non-verification direction is reserved, and the control authority of the mechanical control surface in the verification direction is limited.
Accordingly, step S4 includes: and controlling the jet flow control surface to act in the verification direction, so that the flight platform reaches a new balancing state, and the control performance of the jet flow control surface in the verification direction is verified.
