7–8. PROPULSION SYSTEM
The propulsion system is designed to meet the engine isolation requirements for
multi−engine rotorcraft that are defined by the Category A requirements of FAR
Part 29, paragraph 29.903(b).
Powerplant:
This system consists of two Pratt and Whitney Canada (P&WC) PW206E turbo
shaft engines mounted above the baggage compartment and pointing inboard
to drive into the main transmission gearbox (Ref. Figure 7−13 and Figure 7−14).
Each engine is mounted to the fuselage upper deck by a three point, adjustable
titanium mount. The air inlet which is in the middle of the engine is located
inside a titanium−walled inlet plenum that leads from a flush−mounted inlet
in the side of the cowling. The combuster end of the engine is surrounded by
titanium firewalls forward, aft, inboard side, and below. It is covered by a fairing
door, and is ventilated by an exhaust−driven ejector at the aft end of the compart
ment.
