Программа позволяет производить вычисление аэродинамических коэффициентов самолетов. В архиве содержится исходный код на языке фортран, а также инструкция по запуску программы и описание теории, на основе которой программа была написана.

In preliminary design operations, rapid and economical estimations of
aerodynamic stability and control characteristics are frequently required. The
extensive application of complex automated estimation procedures is often
prohibitive in terms of time and computer cost in such an environment. Similar
inefficiencies accompany hand-calculation procedures, which can require
expenditures of significant man-hours, particularly if configuration trade studies
are involved, or if estimates are desired over a range of flight conditions. The
fundamental purpose of the USAF Stability and Control Datcom is to provide a
systematic summary of methods for estimating stability and control characteristics
In preliminary design applications. Consistent with this philosophy, the
development of the Digital Datcom computer program is an approach to provide
rapid and economical estimation of aerodynamic stability and control
characteristics.
Digital Datcom calculates static stability, high-lift and control device, and
dynamic-derivative characteristics using the methods contained in Sections 4
through 7 of Datcom. The computer program also offer a trim option that
computes control deflections and aerodynamic data for vehicle trim at subsonic
Mach numbers.
The program has been developed an a modular basis as illustrated in Figure 1.
These modules correspond to the primary building blocks referenced in the
program executive. The modular approach was used because it simplified program
development, testing, and modification or expansion.
