3.1.18.3
(Cont)
considered as a source of vibration. When packed for shipment, the target and
all components shall be capable of withstanding without damage the acceleration,
shocks, noise and vibration encountered in shipping and storage.
In
addition, the following shall be included in the design of targets to be operated}
stowed or transmitted on naval vessels:
(1) Shipboard high impact shock conditions.
(2) Adequate consideration shall be given to thexneans of
restraining or gripping targets along each axis during
handling and uncrated stowagee
(3) Adequate protection against shock and vibration, consistent
with other design criteria for unpackaged targets, to preclude
the necessity for special shipping or handling containers aboard ship and for
extensive shipboard shock mitigation systems.
VIBRATION NOISE ESTIMATES. - Realistic, rational estimates
3.1.18.3.1
of natural and induced environments which result in vibratory
Loading of structures and equipment during launch and flight for application to
all target and component design are required. Consideration shall be given in
derivation of estimates to all operating conditions in service and to the effects
of the design configuration on the induced conditions in service and to the
effects of the design configuration on the induced environments The environments
covered shall include structural vibration, radiated and pseudo noise and
oscillatory pressures associated with engine jet effluxes, boundary layer and
wakes, and other similar sources.
3.1.19
- Adequate buoyancy shall be provided to meet the
BUOYANCY.
flotation
requirements specified in the type or detail
specification. Buoyancy maybe
provided by the installation of sufficient approved
bulk flotation material or by
the incorporation of adequate watertight compartments*
3.1.20
MATERIALS AND STANDARD PARTS. - Materials and standard parts
shall conform to applicable specifications and standards
specified herein.
3.1.20.l
SELECTION OF MATERIALS. - Particular attention shall be given
to the selection of parts and materials such as tubing, tie
rods, cables, bolts, nuts rivets, steels, aluminum alloys, etc. to facilitate
interchangeability, stocking and replacement in service. The number of different
types, sizes and strengths of fastenings shall be kept to a minimum. Mere con-
venience in design, procurement, or shop processing is not justification for use
of intermediate sizes, nonstandard parts, or materials which do not conform to
applicable specifications.
