P3 Compare the specific fuel consumption of a turbojet and a ramjet that are being considered for flight at M-1.5 and 50,000 ft altitude (ambient pres- sure and temperature: 11.6 kPa and 205 K, …

Question: A mixture of 65% N2 and 35% CO2 gases (on a mass basis) enters the nozzle of a turbojet engine at 60 psia and 1400 R with a low velocity, and it expands to a pressure of 12 …

7. Calculate the static thrusts of the rocket and turbojet engines described in the figure. The thrust T is the force necessary to prevent horizontal move- R ment of the engine. Both engines …

Q2) Air at 26 kPa, 230 K, and 220 rn/s enters a turbojet engine in flight. The air mass flow rate is 25 kg/s. The compressor pressure ratio is 11, the turbine inlet temperature is 1400 K, and air …

Question: Air enters the diffuser of a turbojet engine with a mass flow rate of 85 lb/s at 9 lbf/in^2, 420 R, and a velocity of 750 ft/s. The pressure ratio for the compressor is 12, and its isentropic …

Question: 9-132 Air at 7°C enters a turbojet engine at a rate of 16 kg/s and at a velocity of 220 m/s (relative to the engine). Air is heated in the combustion chamber at a rate 15,000 kJ/s, and …

An ideal turbojet flies at sea level at a Mach number of 0.75. It ingests 74.83 kg/s of air, and the compressor operates with a total pressure ratio of 15 . The fuel has a heating value of 41,400 …

Aug 11, 2010 · Re: OMC Turbojet 115 HP - Please help! They make a clunking noisy out of the water. Change the gear oil, use the good stuff.

Question: Consider an aircraft powered by a turbojet engine that has a pressure ratio of 9. The aircraft is stationary on the ground, held in position by its brakes.

9.60 Consider the addition of an afterburner to the turbojet in Problem 9.58 that raises the temperature at the inlet of the nozzle to 1260 K. Determine the velocity at the nozzle exit, in …
