abstract = "Deflectable nose control is a new trajectory correction method. In this paper, the aerodynamic andtrajectory characteristics of a typical mortar projectile with a deflectable nose are investigatedwith respect to its flight conditions. Using the method of wind tunnel testing, the aerodynamiccoefficients of four kinds of mortar models were measured under the conditions of differentangles of attack from-10° to 10° and Mach numbers from 0.3 to 0.9. Based on the aerodynamiccoefficients, the trajectory ranges at different nose deflection angles and times were calculated.Furthermore, a trajectory optimization was performed by reducing the static margin. The resultsand discussions show that the nose deflection provided limited lift, while the pitching momentvaried significantly. The mortar obtained the extended flight range and trajectory correctionability with nose deflection. This is an extended abstract of a paper that will be published inDefence Technology, 2019.",
