MIL-DTL-85110B(AS)
s. The RRHB shall be designed so that any internal failure will cause the indicator
devices(s) to show an unsafe condition, and prevent subsequent application of initial
tension loading.
3.3.4 Loads. Strength is required for the catapulting, ground handling, release, and a fatigue
loads as specified in 3.3.4.1 through 3.3.4.4.
3.3.4.1 Ultimate. The RRHB shall have ultimate load limits that will not damage or change
the operating characteristics when the ultimate load test conditions of (a) and (b) are performed
(see 4.2.3.1). Ultimate load test conditions are :
a. Maximum tensile load of the RRHB shall be (1.50) times (1.06) times the "R" value as
defined in MIL-A-8863.
b. RRHB rigidly supported at both ends and a 400 pound static load applied in any direction
at the midpoint normal to the longitudinal axis.
3.3.4.2 Endurance. The components must withstand the entire fatigue spectrum of Figure 1
for catapulting loads, including a scatter factor of 2.0 both by analysis and the endurance tests of
4.2.3.5.
3.3.4.3 Release. Release loads shall be those specified in MIL-A-8863.
3.3.4.4 Overload. The overload control section shall be designed in such a manner that the
aircraft will never be loads greater than 1.60R (see 3.3.3(p) and 3.3.4.1 (a)) due to the bar
malfunctioning.
3.3.5 Environmental. The RRHB shall operate satisfactorily with no malfunctions under any
of the following environmental conditions (see 3.3.5.1 through 3.3.5.7) or combinations of these
conditions as specified herein.
3.3.5.1 Temperature. The RRHB shall operate satisfactorily with no malfunctions when
subjected to the ambient temperature ranges and conditions of (a) and (b) and the high and low
temperature of 4.2.2.2 and 4.2.2.3.
a. Storage
- -70°F to +160°F for extended period of time.
b. Operating -
Air, -40°F to +160°F at sea level.
3.3.5.2 Low pressure. The RRHB shall operate satisfactorily with no malfunctions when
subjected to the low pressure atmosphere and the low pressure atmosphere and the low pressure
tests of 4.2.2.1.
