[B] Projectile Flight: The Problem Formulation, Solution, Predictions
Abstract
This report is dedicated to the issue of calculating air resistance to the flight of projectiles. The method used was previously developed in the work "On the Air Resistance to a Projectile Flight".
The same examples as in the soars are used to determine additional flight parameters. Their numerical values can be used for the selection of appropriate means to solve the problem – air removing from the trajectory.
Formulas have been developed to determine the flight design functions.
A computational assessment has been carried out for range and speed performance in the presence of air resistance two times lower than existed.
The obtained data can be used for both functional and commercial evaluation of solutions.

[C] 155 mm Projectile Flight Design Function
Abstract.
This work defines the flight characteristics of the 155 mm projectile with enhanced aerodynamic properties. The optimization of properties was carried out based on an original physical flight model with atmospheric air resistance.
An example of comparative calculations of projectile flight along an overhead trajectory is provided.
As a result, the impact (damage) radius, compared to the standard projectile shape, can be increased by more than one and a half times.
