Unformatted text preview: 650:460 Aerodynamics Homework Assignment No. 9 Prof. Doyle Knight Tel: 732 445 4464, Email: doyleknight@gmail.com Office hours: Tues and Thur, 4:30 pm - 6:00 pm and by appointment Fall 2009 1 Problem 8.17 Consider the two dimensional inlet for a turbojet engine. The upper surface deflects the flow 10 , and the lower surface 5 . The freestream Mach number is 2.5 and the pressure p 1 = 5 10 3 Pa. Calculate the static pressure, the Mach number and the flow direction in regions (2), (3) and (4) and (5). Note that since regions (4) and (5) are divided by a fluid/fluid interface, that p 4 = p 5 and the flow direction is the same in regions (4) and (5)). 2 Problem 8.l7 Region2 The flow deflection angle 2 = 5 . From Fig. 8.12, 2 = 27 . 4 . Using the equations on pp. 413-414, p 2 p 1 = 1 . 380 M 2 = 2 . 292 Region 3 The flow deflection angle 3 = 10 . From Fig. 8.12, 3 = 31 . 9 ....
