MIL-HDBK-336 -2

Abstract

This is the second volume in a four-volume design handbook for nonnuclear survivability of military aircraft. Each volume is structured to be used in conjunction with the other three volumes, as needed, in the design process. This volume contains specific subsystem design concepts, procedures, and other pertinent information. The information and design guidance contained in this volume is arranged in a manner to enhance its use in the conceptual design process, system research, design, test, and evaluation (RDT&E) programs, and existing aircraft modification programs where nonnuclear survivability features are required. Specific information pertinent to each subsystem is contained therein. This volume is arranged to permit the designer or analyst to select the specific area or subject of concern in the design or modification of an aircraft system and find the candidate design methods that may be considered for use. Table 1-I is a matrix of the general survivability enhancement methods and the subsystems associated with military aircraft. The general applicability of the listed methods, for each subsystem, is indicated by a dot in the matrix. This serves as a preliminary check list for the user to ensure that all potential candidate survivability enhancement methods are considered. The use of this chart is an essential step in the process of selecting the most effective combination of survival enhancement features for the given aircraft design concept. <br>The data contained in this design handbook have been arranged to support the development of both fixed and rotary wing military aircraft. Each has unique mission and performance characteristics that require specialized attention and design solutions. The subsystem design categories have been established with these considerations in mind. For example, the power train and rotor blade subsystems deal primarily with military helicopter applications, while the launch/recovery systems deal with those subsystem elements for both fixed and rotary wing aircraft landing gear systems and for those systems related to the assisted takeoff (launching) and deceleration (recovery) methods most used by the Air Force and Navy fixed-wing aircraft. <a name="TNSSDAAAAAAAAAAA-X7" id="TNSSDAAAAAAAAAAA-X7"><img alt="TABLE 1-I.
