(s) Maximum and normal system temperature (estimated).
In estimating maximum and normal system temperatures, the following con-
ditions should be specified:
(1)
Location of temperature.
(2)
Altitude
(3)
Ambient temperature
(4)
Compartment temperature
(5)
Engine power setting
(6)
Time duration of flight at maximum system
temperature.
(t) Pressure and temperature pickup locations to be
installed for instrumentation purposes in accordance with MIL-T-5522 should
be indicated on the copies of the schematic diagrams submitted to the pro-
curing activity.
(u) Hydraulic system block diagram. (This may be a
separate sheet of the schematic diagram.)
Hydraulic system design report - The hydraulic system
6.2.4
design report should be submitted prior to or with the final schematic
diagram, The report should incorporate sufficient design calculations and
data to verify that the hydraulic system design complies with all design
requirements. A hydraulic system temperature survey (minimum through
maximum) should be included considering the location of the hydraulic system
in the vehicle. The time of flight at maximum system temperature and condi-
tions under which this temperature occurs should be included. Compartment
temperatures should be estimated. For primary flight-control systems, peak
and average flow rates and the power spectrum should be indicated. Duration
of peak flow rates should also be indicated. The minimum temperature at
which full performance occurs should be determined by the contractor and
submitted for approval.
Hydraulic system nonstandard component cross-sectional
6.2.5
assembly drawings - The cross-sectional assembly drawings for each non-
standard hydraulic component should contain sufficient information in order
that an evaluation of the unit can be made. Such information should include
the applicable specification, the material protective finish of each part,
and bearing data. This information may appear as a written addition to the
drawing. Reason for the use of a nonstandard component, where a standard
exists, should be submitted with the component drawing.
Functional mockup design report and test program - A
6.2.6
report describing the general design of the functional mockup and the
anticipated test-program should be-submitted to the procuring activity for
approval not later than 30 days prior to beginning construction of the mock-
up, in order that any modification of the mockup or revision of the test
program recommended by the procuring activity may be included.
