Introduction to T-45C Configuration
T-45C TS, ADV & IUT ENG-01
1.
Description: two independent systems (HYD 1 and
HYD 2) consisting of engine-driven pumps (EDPs)
reservoirs, and accumulators. An associated part of
HYD 2 is an emergency HYD system, with ram air
turbine (RAT) supplying emergency hydraulic power
back-up for HYD 2 EDP
2.
Function: both independent systems provide
constant 3000 psi
a.
HYD 1 powers flight controls (stabilator and
ailerons) and general services (speed brakes,
flaps, slats, landing gear, wheel brakes, anti-
skid, launch bar, nose wheel steering, and
arresting hook)
b.
HYD 2 powers flight controls and emergency
assembly package
c.
RAT powers flight controls through emergency
HYD system following a failure of the HYD 2
EDP
3.
Control location: HYD 2 RESET button--left
console, forward of throttle, both cockpits
E.
Flaps/slats, speed brakes 1.4.19.3.1.1
NOTE: Since during normal operation full slat extension
occurs with any half or down flap condition, reference to
slats is omitted in some subsequent discussion of flaps.
1.
Description: flaps inboard at trailing edge of each
wing, slats full span on leading edge of wing, and
speed brakes on each side of aft fuselage
2.
Function
a.
Flaps augment lift at lower airspeeds
b.
Slats decrease stall speed and increase aircraft
control and stability
