Abstract:
1. An aircraft having a user region therein bounded at least in part by boundary walls within which pressurized air at selected pressures can be maintained using an environmental control system provided in the aircraft, and a utility region outside a utility boundary wall of the user region within which selected equipment for the aircraft is located, the aircraft comprising: an internal combustion engine provided as an intermittent combustion engine in the utility region having an air intake coupled to combustion chambers therein and a rotatable output shaft also coupled to those combustion chambers for generating force; an air transfer duct extending between an opening in the utility boundary wall, so as to be capable of having pressurized air in the user region enter that air transfer duct at one end thereof, and also being connected to the air intake at an opposite end thereof so as to be capable of conveying pressurized air therein to that air intake; a supercharger capable of receiving air from the atmosphere through an emergency supply duct located in the utility region and providing compressed air in a supercharger duct interconnected to the air transfer duct to provide the compressed air to the air intake of the intermittent combustion engine; a radiator and a pair of hoses connected thereto and to coolant passageways in the intermittent combustion engine to allow circulation of a coolant between those passageways and the radiator to thereby cool that engine; a radiator fan that is rotatable to draw air through the radiator; a vent in the utility region through which the radiator fan draws air; and a heat removal duct extending from the radiator fan to an outlet vent in the utility region.
