The aft section includes the structure for the tailboom attachment and en-
gine compartment. Access to the engine compartment is provided through
clamshell doors contoured to the shape the fuselage.
The lower section is divided by the center beam and provides a housing for
the two fuel cells. Provisions for the attachment of a cargo hook are located
on the bottom of the fuselage in line with the center beam.
The tailboom is a monocoque structure of aluminum alloy frames and skin.
The tailboom is the supporting attachment structure for the stabilizers, tail
rotor transmission and tail rotor. The tailboom also houses the tail rotor
transmission drive shaft; the one−piece dynamically balanced shaft requires
no intermediate couplings or bearings.
Landing gear:
The landing gear is a skid−type attached to the fuselage at 12 points and is
not retractable. Aerodynamic fairings cover the struts. Nitrogen charged
landing gear dampers act as springs and shock absorbers to cushion land-
ings and provide ground resonance stability. Provisions for ground handling
wheels are incorporated on the skid tubes.
Helicopter interior:
The standard MD 500E requires a minimum crew of one pilot seated on the
left side of the cockpit. The passengers sit to the right, abreast of the pilot.
Seat belts are provided for all positions. In the military version, the center
seat is eliminated.
An instrument panel is located forward of the seat at the aircraft center-
line. The panel incorporates standard flight and engine instruments in addi-
tion to warning and caution lights. The panel also contains adequate space
provisions for various arrangements of communication and navigation equip-
ment.
Seat belts are provided with several styles being offered. The seats and
belts are easily removed. Cargo compartment bench−type seats may be easi-
ly folded out of the way or completely removed for accommodating cargo.
During cargo carrying operations, the compartment floor serves as the cargo
deck. Removable and interchangeable cargo tiedown fittings are available.
Four doors are installed on the helicopter−two on each side. The two for-
ward doors permit access to the forward compartment for pilot and passen-
gers. The two aft doors allow entry to the passenger/cargo compartment.
Transparent tinted windows are contained in the doors.
Power plant:
The power plant used is either the Allison Model 250−C20B or 250−C20R/2
gas turbine engine with a takeoff power rating of 420shp for the C20B and
450shp for the C20R/2. Only 375 shp at 103 percent N2 RPM is used for
takeoff; 350 maximum continuous shp provides sufficient power for all other
flight modes.
