An aircraft is flying at 440 km/hr at 3 km on a standard day. What is the aircraft Mach Number?
Stagnation pressure and temperature probes are located on the nose of a supersonic aircraft. At 35,000 ft altitude a normal shock stands in front of the probes. The temperature probe indicates T0 = 420F behind the shock. Calculate the Mach number and air speed of the plane. Find the static and stagnation pressures behind the shock. Show the process and the static and stagnation state points on a Ts diagram.
QUESTION 14 The fan of a turbofan engine is tested at high speed. The flow approaches the fan tip at a relative Mach number M1rel = 1.19. An oblique shock forms at the fan tip leading edge, with a shock angle B = 87 degrees. Use cold-air- standard assumptions and the two-dimensional oblique shock formulae to determine the relative Mach number M2rel after the shock. State your answer to two decimal places. Partial credit is awarded for a reasonable approximation to the correct numerical answer. %3D
