Through simulating atmospheric corrosion accelerating test in laboratory for single-row tube\'s aluminium fines(A303) in acid rain area,the difference of air side resistance and thermodynamic property of single-row tube bundle before and after corosion has been studied.

Influence of form of train formation on running air resistance;

The influence of air resistance on the moving Coriolis projectile;

Influence of air resistance on the vibration period of compound pendulum;

This spatial configuration is caused mainly by air drag, but the exact form of the curve is complicated to calculate.

In studying the characteristics of increasing drag for different damper structures, the paper gives several structures and ten schemes for the damper of one-dimensional trajectory correcting fuze (1D TCF) for a mortar shell, measures the air drag on the mortar munition installed with one-dimensional trajectory correcting fuze under 0 degree nutation angle and low wind speed.

Experimental Investigation of Hydraulic Model for Aerodynamic Drag of High Speed Train in Tunnels;

Numerical simulation research on train aerodynamic drag affected by the train windshield;

Analytic Calculation of Piston Wind Velocity and Aerodynamic Drag in High-Speed Train Tunnel;

The earth rotation and the air drag force are both influencing to the kinematics of a projectile.

The kinematics of an east horizontal projectile in the northern hemisphere are both influenced by the air drag force and the earth′s rotation.

In order to comprehensively discuss the kinematical equation and the expression for drift of a projectile in the northern hemisphere, the influence of the earth ratation and the air drag force are both considered.
