Measuring the e ects of lift and drag on projectile motion.

Irrespective of its speed, the drag force (the air resistance) acts in the opposite di- rection of the motion retarding its movement. In Figure 1, a snapshot of a flying ball with its instantaneous ve- locity and the drag force are shown with vand F D, respectively. To obtain an accurate prediction of the spinning effect on individual drag components and total drag of a projectile for the shell design, the implicit, diagonalied, symmetric total variation diminishing (tvd) scheme, accompanied by a suitable grid, is employed to solve the thin‐layer axisymmetric navier‐stokes equations associated with the.

Measuring the Effects of Lift and Drag on Projectile Motion.

5. Conclusions. The article establishes a seven-DOF projectile trajectory model of a dual-spinning projectile. After analyzing the ballistic characteristics of the dual-spinning projectile with the method of numerical simulation, it can be seen that the major distinction between the dual-spinning projectile and the traditional spinning projectile is that the forebody and the afterbody show.

Values of angles of attack and different spin rates. The former is varied in the range of 0-34 , and the non-di-mensional spin rates considered are X = 0.03, 0.04 and 0.05. At all these conditions, various aerodynamics forces such as lift, drag and side forces are measured using a three-component strain gauge balance connected to a digital load.

Aerodynamic characteristics of an ogive-nose spinning projectile.

Minimizing the aerodynamic drag has been a major concern in the field of ballistics in order to increase the performance of projectiles and missiles. The reason behind the increase in aerodynamic drag acting over the projectile is due to the flow separation occurring at the rear end of the body leading to the formation of wake.

. Previous research studies indicate that the proportion of Magnus force at the spinning projectile tail position is very high. Meanwhile, the large mutations of aerodynamic characteristics are found after adding boattail structures. In order to study the influences of boattail structures on aerodynamics of a spinning projectile, a 6.37-diameter long tangential-ogive-cylinder projectile is..
