    An improved combined method of creating control forces and moments for an unmanned aerialvehicle by A. V. Lopuhov

    Published 2022-06-01
    “…improved combined (aerodynamic and gas-dynamic) method of creating control forces and moments.The objectives of the study are to analyze the basic model of the combined control method and the possibility of using an improved model of the combined control method, at which the invariability of the mass and dimensional characteristics of the upgraded control object will be achieved with a simultaneous increase in the target quality (reduction of the final miss).Research is based on the use of an improved method for creating control forces and moments, where the optimization of mass characteristics is made, for using of a smaller number of micropulse motors (only at the stages of acceleration and braking), and when setting the balancing position (maintaining a steady angle of attack), instead of impulse engines, a steering drive is used standard onboard stabilization system of an unmanned aerial vehicle aerodynamic control channel. …”

    RESEARCH ON THE OPTIMAL DESIGN METHOD OF U-SHAPED SECTION CONTAINMENT RING

    Published 2024-01-01
    “…U-shaped containment ring is usually used as protection device for turbine starters.Under the condition that the turbine rotor is contained,structural optimization of the U-shaped section containment ring was carried out to obtain a light and inclusive structure,which improved aircraft safety and thrust-to-weight ratio.An optimal design method for U-shaped cross section containment ring was proposed.The method adopted the optimal Latin hypercube design,numerical simulation,response surface modeling,and multi-island genetic algorithm to achieve the optimal design of multiple parameters of containment rings cross section.By combining simulation and experiment,the influence weights of different structural parameters on the residual kinetic energy of debris and the volume of containment rings were analyzed.The influence of different structural parameters of Ushaped containment ring on the containment results was studied.Containment test was carried out to verify the optimized containment ring.The results show that the thickness of the containment ring has the greatest influence on the residual kinetic energy of the debris,and the weight ratio is 38%.The main structural parameters affect the inclusion effect are thickness and groove depth.The error of inclusion ring deformation is less than 2%in the comparison between simulation and test results,which indicates that the optimization design method proposed is reasonable and reliable.The research results can provide prior knowledge and optimization methods for the quality reduction of U-shaped containment ring structures.…”
