Herrmann Ernest Edward. Exterior ballistics

Annapolis, Maryland: U.S. Naval Institute, 1935.Exterior ballistics: a textbook of those elements of exterior ballistics which are the fundamentals of naval gunnery, written for the use of midshipmen at the United States Naval Academy. /file/2266389/Definitions and introductory explanations Preliminary assumptions.
The equation of the trajectory in vacuum. The theory of rigidity of the trajectory.
The retardation of the projectile due to resistance of the atmosphere. The coefficient of form. The ballistic coefficient.
The differential equations of motion of a projectile in air and Siacci's method of solving them.
The solution of the trajectory in air by the numerical-integration method.
The construction and use of ballistic tables based on numerical integration.
The determination of initial velocity and coefficient of form by experimental firing at the proving ground. The determination of range-table values of range, angle of departure, angle of fall, time of flight, striking velocity, and maximum ordinate (range-table columns 1, 2, 3, 4, 5, and 8).

The determination of the effects of variations from range-table standards for initial velocity, weight of projectile, and atmospheric density (range-table columns 10, 11, and 12).
The determination of the effects of wind and motion of gun on the trajectory, and of motion of target on the point of fall with respect to the target (range-table columns 13—18).
