Aerodynamic Accounting Technique for Determining Effects of Nuclear Damage to Aircraft. Volume 1, Empirical Methods
Abstract
This volume presents the methods, equations and substantiating data for an empirically based computer program which calculates lift, moment, and drag characteristics of an undamaged baseline aircraft in addition to calculating the aerodynamics of an aircraft which has sustained nuclear damage. The input requires a simple definition of the basic undamaged configuration geometry along with parameters specifying the mode of damage, magnitude, and dimension of the damaged area. Up to fourteen different modes of damage can be specified which can model most types of damage. The computer code has the capability of assessing the aerodynamics effects of damage, such as rough, bent, and burnt skins, boundary-layer thickness effects, and loss of radomes, panels, doors and covers. Also, the computer code has the capability of analyzing changes in drag due to lift and trim caused by asymmetric loss of parts of the wing or trim surfaces. The accuracy of the program is verified through comparisons of the predicted results with experimental data for several configurations.
