Aeronautical Design Standard, United States Army Aviation and Missile Command - Air Vehicle Technical Description

This standard practice Aeronautical Design Standard specifies the air vehicle technical
data necessary to perform a detailed analysis of the performance, handling qualities, rotor
dynamics, airframe dynamics, acoustics and engine/drive train response characteristics of
proposed new development or derivative rotorcraft. The purpose of this standard is to
provide a clear technical description of the proposed air vehicle and its components at a
level of detail consistent with the current stage of its design. To this end, the data
requirements are divided into topics and the topics are divided into three levels: Level 1,
Level II, and Level III. Level I (minimum) requires sufficient information to conduct a
basic performance and stability and control analysis including the aerodynamic effects of
the rotor system and the fuselage. Level II (intermediate) requires all of the data required
for Level I plus additional data required for more detailed rotor and fuselage
aerodynamics analyses, a basic dynamic analysis of the rotors and the fuselage and a
basic analysis of engine/airframe response characteristics. Level III (detailed) is intended
to allow a very detailed aerodynamic and dynamic analysis.

This standard practice Aeronautical Design Standard is a communications tool. It is
intended to provide a standard nomenclature and format for providing a technical
description of the design. This standard contains a set of requirements designed to be
tailored for each contract by the contracting agency. The tailoring process intended for
this standard is the deletion of non-applicable requirements.
