AbstractThe vortex valve solid variable thrust motor is a new solid motor which can achieve Vehicle system trajectory optimization and motor energy management. Numerical calculation was performed to investigate the influence of vortex chamber diameter, vortex chamber shape, and vortex chamber height of the vortex valve solid variable thrust motor on modulation performance. The test results verified that the calculation results are consistent with laboratory results with a maximum error of 9.5%. The research drew the following major conclusions: the optimal modulation performance was achieved in a cylindrical vortex chamber, increasing the vortex chamber diameter improved the modulation performance of the vortex valve solid variable thrust motor, optimal modulation performance could be achieved when the height of the vortex chamber is half of the vortex chamber outlet diameter, and the hot gas control flow could result in an enhancement of modulation performance. The results can provide the basis for establishing the design method of the vortex valve solid variable thrust motor.

Variational design is an efficient method for product design; statistics indicates that about 70% of product design is attributed to variational design. It is of vital importance for enterprises to achieve a complex new product through variational design while reusing the previous part model series, which can mostly improve their capability and efficiency of product design and development. Therefore, this paper puts forward an efficient variational design method based on a master model which is automatically generated from a part model series. Using the method, the designers can easily and efficiently create a new part from the master model only through feature selection and parameter modification. In this way, the work of the designers can be greatly alleviated and the design time can be greatly reduced. Experimental results show that the proposed method is effective.
