GAS DYNAMICS 4.14 A supersonic inlet is to be designed to operate at Mach 3.0. Two possibilities are con- sidered, as shown in Figure 4.48. In one, the compression and deceleration of the flow takes place through a single normal shock (Figure 4.48a); in the other, a wedge-shaped Figure 4.47 A supersonic inlet.

Question 2.8 Refering to the figure below, a supersonic flow with upstream Mach number, M, static pressure, pi, and static temperature, Ti, as specified in the table below, encounters a corner with a turning angle ore Determine the angle of the oblique shock, ?, the angle of the reflected wave, q, the Mach numbers M2 and M, and the downstream static pressure Ps and static temperature Ty Mi P1 M3 P3 T3 Design Data Value Unit Mach number (M) Static...
Can you please do this question correctly. Thanks!! 08 Question 2.7 Two possibilities are considered for the design of a two-dimensional jet engine inlet as shown in the figures (a-b) below. The inlet is to operate at the Mach number Mi, shown in the table below. In the first design configuration, shown in figure (a), the deceleration of the flow takes place through a normal shock. For the second case, shown in figure (b), a wedge-shaped diffuser is used to...
Question 3 - 70 Marks In this question we are considering a scramjet engine. A scramjet engine is a high-speed propulsion engine which begins working at approximately Mach 5. Similar to a regular jet engine, the air is compressed in the inlet, fuel is added and combustion occurs in the combustion chamber and the higher pressure and temperature mixture is then exhausted through a nozzle to provide thrust. Unlike a conventional jet engine the air is compressed using the shock...
