ENGINE COOLING SYSTEMS 1. What is meant by pressure cooling of an aircraft engine? - CORRECT ANSWER -Air cooling in which air is forced to flow through baffles and cylinder fins by a pressure differential across the engine. 2. What is the purpose of an augmentor tube in the cooling system of an aircraft reciprocating engine? - CORRECT ANSWER -The augmentor tube uses the velocity of the exhaust gases to produce a low pressure on one side of the engine that helps pull cooling air through it. 3. Where is the highest temperature located in a turbine engine? - CORRECT ANSWER -At the inlet to the high-pressure turbine. 4. How are the turbine inlet guide vanes and the first-stage turbine blades in some turbine engines cooled? - CORRECT ANSWER -High-pressure compressor bleed air flows through the hollow guide vanes and hollow turbine blades. 5. Which side of an air-cooled engine cylinder has the greatest amount of cooling fins? - CORRECT ANSWER -The side of the cylinder in which the exhaust valve is located. 6. What should be done to repair a bent cooling fin in a cast aluminum cylinder head? - CORRECT ANSWER -It is normally best to leave a bent cast fin alone if it does not restrict the flow of air. Cast fins are brittle and could break off. 7. What is used in a helicopter to increase the amount of cooling air that flows over the engine cylinders? - CORRECT ANSWER -A belt-driven fan. 8. What should be the position of the cowl flaps on a reciprocating engine when it is run on the ground? - CORRECT ANSWER -They should be wide open when operating the engine on the ground.
