If the Mach number at the nozzle exit is 3, calculate the exit pressure. 0.37x104 N/m2 1.37x104 N/m2 2.37x104 N/m2 3.37x104 N/m2 1 2 3 4 None When five is added to three more than a certain number, the result is 19. What is the number? a) 10 b) 11 c) 12 d) 13 None The regime of flight from the critical Mach number up to M = 1.3 is called the A. transonic range B. supersonic range C. hypersonic range D. subsonic range None Air passes a normal shock wave. Which of the following statements is correct? A. The temperature increases B. The pressure decreases C. The temperature decreases D. The velocity increases None A commercial jet aeroplane is performing a straight descent at a constant Mach Number with constant weight. The operational limit that may be exceeded is: A. VNE B. VD C. MMO D. VMO None The static pressure is acting A. only perpendicular to the direction of the flow B. only in the direction of the total pressure C. in all directions D. only in direction of the flow None When the air has passed through a normal shock wave the Mach number is A. lower than before but still greater than 1 B. equal to 1 C. higher than before D. less than 1 None Climbing at a constant Mach Number up to FL 350 the TAS will: A. remain constant B. decrease C. first increase, then decrease D. increase None The 16-ft wing of an airplane is subjected to lift which varies from zero at tip to 360 lb/ft at the fuselage according to w=90x1/2 lb/ft where x is measured from the tip. For questions VA is? A. the speed that should not be exceeded in the climb B. the maximum speed at which maximum elevator deflection up is allowed C. the maximum speed at which rolls are allowed D. the speed at which a heavy transport aeroplane should fly in turbulence None Lift is generated when? A. a certain mass of air is accelerated downwards B. the shape of the aerofoil is slightly cambered C. an aerofoil is placed in a high velocity air stream D. a certain mass of air is retarded None Please fill in the comment box below if you have questions or concern : Time's upTime is Up!
