Selection and Characterization of Critical Missiles.

Aircraft subcategories identified in the site-specific hazard

study (see Chapter 5) should be considered as sources of

missiles for the facility being evaluated. The mass, velocity,

and stiffness characteristics and configuration of these aircraft

subcategories and their major heavy and rigid components

should be used to select the critical missiles.

Nondeformable missiles are the rigid and heavy components

(e.g., landing gear, engine shaft) of the aircraft. Deformable

missiles are relatively soft components (e.g., wings, fuselage).

As evidenced in some recent tests, aircraft engines deform

significantly upon impact with rigid barriers and hence can be

considered as deformable. Critical missiles should be

selected by considering the three adverse effects listed in

Section 6.1.1. The local damage evaluation should be

performed using relatively nondeformable components of the

aircraft as the candidate missiles. Typically, the aircraft as a

whole is critical for global response evaluation. For SSC

functionality evaluation, the whole aircraft and its rigid and

heavy components can be critical.

In selecting critical missiles, consideration should also be

given to the relative location, orientation, and configuration of

SSCs and their barriers at the facility.

When more than one missile can potentially impact a target,

select the missile with the maximum kinetic energy as the

critical missile for global response evaluation. For local

response, also consider the penetration characteristics of the
