Question
Now suppose that your supersonic vehicle is cruising at a velocity of 2178 m/s and the estimated engine specific impulse is 1050 sec. It cruises at a constant lift-to-drag ratio of 2.5. The vehicle takeoff weight is 70 kN, and 40% of this weight is the fuel. Compute the range in km. Will you make it from LA to Tokyo with this amount of
fuel ?

- An airplane approaches at an altitude of 10 km flying at 600 km/hr. 1. What would you hear, and when would you hear it, if the plane were "hypersonic", traveling three times the speed of sound, or "Mach 3"? That's approximately the fastest military aircraft in routine service today. note: To have higher speeds in the air takes considerably more energy. For example, after two and half minutes of flight, when the first-stage main engines of the Space X Falcon shut down, it is 80 kilometers high and moving at Mach 10 on its way to Earth orbit. The Mach number depends on the temperature of the air.arrow_forward!arrow_forwardb) degree. Calculate the static temperature of the air and the velocity of the projectile when the relative total temperature of the air in which it is travelling is 15 °C. The ratio of specific heats for air is 1.4 and its gas constant is 287 kJ/kg-K.

The NASA X-43 flies at a Mach number of 9.4 at an altitude of 30,000 m, where thepressure is 1171.8 Pa and the temperature is 226 K. If a supersonic wind tunnel isdesigned to reproduce these conditions, calculate the following:(a) The velocity (m/s), total/stagnation temperature (K), and total/stagnation pres-sure (kPa) in the test section.(b) The velocity (m/s), total temperature (K), and total pressure (kPa) behind thenormal shock formed in front of a blunt surface in the test section.(c) The change in entropy across this normal shock.arrow_forward

- Please show all work of a,b,&c. A supersonic converging-diverging nozzle is near the exit of a turbojet engine. Its cross-section is circular. The gas has the properties of air, and the flow is isentropic. At the throat location (the minimum area) the air flow is choked (is Mach one) and the throat has diameter of 20 cm.arrow_forward5.7 When the reservoir pressure and temperature of a supersonic wind tunnel are 15 atm and 750 K, respectively, the mass flow is 1.5 kg/s. If the reservoir conditions are changed to p, 20 atm and T, = 600 K, calculate the mass flow.arrow_forwardLong flights at midlatitudes in the Northern Hemisphere encounter the jet stream, an eastward airflow that can affect a plane's speed relative to Earth's surface. If a pilot maintains a certain speed relative to the air (the plane's airspeed), the speed relative to the surface (the plane's ground speed) is more when the flight is in the direction of the jet stream and less when the flight is opposite the jet stream. Suppose a round-trip flight is scheduled between two cities separated by 3200 km, with the outgoing flight in the direction of the jet stream and the return flight opposite it. The airline computer advises an airspeed of 810 km/h, for which the difference in flight times for the outgoing and return flights is 72 min. What jet-stream speed is the computer using?arrow_forward
