aerodynamic trajectory
1.Objective:To observe clinical effect and complications of treating ureterolith through aerodynamic trajectory lithotrity by ureterorenoscope(URS).
2.Conclusion:The treatment of ureterolith through aerodynamic trajectory lithotrity by URS has such advantages as high cure rate and safety,minimal invasiveness,reduced complications and low expense,etc. It may serve as a choice of method to treat ureterolith.
3.The importance of VV&A (Verification, Validation & Accreditation) was discussed. Several basic principles of VV&A of aerodynamic missile trajectory simulation were put forward.
4.A GREEN FUNCTION METHOD FOR THE INVESTIGATION OF AERODYNAMIC IMPACT UPON THE INITIAL TRAJECTORY OF THE BOMB
5.The article introduces a method about setting up a model of plane trajectory aerodynamic coefficient on reentry segment.
6.In the sensitivity analysis of the trajectory were considered the sensitivities to variations of aerodynamic models, release parameters, control commands and to gusts.
7.The particle trajectory is calculated with certain amoune of selected control rules by establishing mathematical mod els such as whole missile mass calculation model,aerodynamic estimation model and turbojet engine performance interpolation.
8.In this paper, the optimization problem of reentry trajectory and aerodynamic heating history of the space shuttle has been discussed using the modern control theory by selecting the attack angle and the bank angle as control variables.
