3. The Rolls-Royce Olympus 593 is the turbojet engine used to power the Concorde. It has a static sea-level thrust (To) of 28,800 lbf when operating at maximum continuous power on a standard day. a. What is the thrust at Mach 0.3 if the engine is operating at sea level? (1 point) b. What is the thrust at Mach 0.3 if the engine is operating at 10,000 ft? (1 point) 4. The Cessna 172 is a propeller-driven general aviation aircraft. It features a propeller with a diameter of 76 inches which is driven by Lycoming O-360 reciprocating engine. The O-360 produces 180 horsepower at sea level. c. What is the shaft brake power if the vehicle is operating at Mach 0.15 at sea level? (1 point) d. What is the shaft brake power if the vehicle is operating at Mach 0.2 at 10,000 ft? (1 point) e. The aircraft is cruising at 10,000 ft, maintaining a velocity of 192 ft/s with the propeller spinning at 2500 revolutions per minute. What is the advance ratio of the propeller at this condition? (1 point) f. While in the cruise condition above, the engine throttle is set to approximately 60%. Assuming a propeller efficiency of 0.85, what is the available power produced by the propeller? (1 point) g. For the same cruise condition, what is the thrust produced by the propeller? (1 point) 3. The Rolls-Royce Olympus 593 is the turbojet engine used to power the Concorde.
